Full textAbstract:
Population growth in regions of the Intermountain West has resulted in rapid growth of residential neighborhoods. In Utah, the landscapes associated with these expanding neighborhoods consume vast quantities of treated water. This is a concern in all states of the Intermountain West, as water becomes increasingly scarce. Traditionally used turfgrasses, trees and other plants in Intermountain West landscapes require significant amounts of supplemental water considering the intense sunlight, dry winds and sparse rainfall typical of the region. Characterizing the interactions between turfgrass and tree species in these landscapes can aid in the identification of candidate species that consume less nutritional and water resources, while maintaining satisfactory appearance. A study was conducted investigating the nature of interactions between tree and turfgrass species in a constructed landscape of the Intermountain West. An experiment was performed investigating differences in rooting length and volume between combinations of two tree (Robinia pseudoacacia L., Gleditsia triacanthos var. inermis L.) and three turfgrass [Poa pratensis L., Buchlöe dactyloides (Nutt.) Engelm., Festuca arundinacea Schreb.] species. A minirhizotron system was used to obtain root images at three times during the growing seasons of 2006 and 2007 at depths from 1-15 cm in each tree-turfgrass rooting zone. Images were analyzed to determine combined total volume, length, and surface area of turfgrass and tree roots. This research shows that root growth differences occur in turfgrass-tree combinations containing all three turfgrass species. Buffalograss best resisted possible root growth inhibition, regardless of tree combination. Further evidence shows that Robinia secondary growth is vulnerable to presence of turfgrass in proximity.

Full textAbstract:
The purpose of this thesis is to design a landscape plan for Teaching Gardens at the Western Kentucky University Agriculture Research and Education Center. The landscape plans were selected based upon the available 5.3 acres surrounding the greenhouse, vineyard, and Exposition Center. Planning included goals and objectives, analysis of the available site, landscape design plans, and connecting the Teaching Gardens to the current curriculum. This thesis also includes related areas to the development of Teaching Gardens such as: summary of courses with related topics to Teaching Gardens, programs that will be used throughout the community, and a listing of current and estimated future costs/expenses plus funding avenues to support this endeavor. The implementation of the Gardens in this thesis has created an area of learning for the Agriculture Department, university, and local community. The Teaching Gardens are an extension of the classroom learning experience, which provide research opportunities, harvest/care information, and promote healthy nutrition. The Teaching Gardens provide a naturally beautiful atmosphere for the enjoyment of students, faculty and staff, and the local community.

Full textAbstract:
This thesis project created a landscape design framework for the Student Garden at the College of Charleston that took into account stakeholder needs and landscape constraints, thereby allowing the Garden to better fulfill its mission. Steps for this project were to perform a stakeholder analysis to determine perceptions of mission, vision, and needs for the Garden. This was then paired with a landscape suitability assessment. The assessment was performed in GIS using available soil data from the Soil Survey Geographic Database (SSURGO) to analyze for agricultural suitability.
Based on interview data, stakeholders considered the main mission of the Garden to lie in three areas: education, student research projects, and vegetable production. Landscape suitability analysis determined that the Garden was situated in the least favorable location within its available land area from an ecosystem standpoint. The landscape design incorporated the stakeholder needs of education, research, and production while proposing an expansion in a new, more centralized location that has soil better suited for agriculture along with new infrastructure. It incorporated a centralized building with office, rest area, and shaded work area that has facilities approved for vegetable processing for the CSA. Adjoining the building are beds showcasing sustainable agricultural techniques, greenhouses for seed starting and production, area for a food forest, and open fields for row crops.

Full textAbstract:
ABSTRACT EFFECTS OF RECYCLED WATER ON LANDSCAPE PLANTS Casey Ray Miranda Recycled water is water that has been previously used, has suffered a loss of quality, and has been properly treated for redistribution (Wu et al. 2001). The use of recycled water as an alternative to fresh water in the landscape can have positive and negative effects. Experimentation on 40 different plant species during a 32 week period (2 phases of 16 weeks), was conducted to analyze the effects of recycled water irrigation on the appearance of landscape plants. Each species of plant was planted into 10 individual number 2 pots and irrigated with recycled water daily. Media and water were tested for nutrients and other constituents. In phase I there were four different species of grasses and grass-like plants, five different perennials, five species of shrubs, and four annuals tested; while phase II tested four species of herbaceous perennials, eight different species of shrubs, six species of groundcovers, and four species of annuals. All tests were conducted at the Paso Robles Waste Water Treatment Plant. Of the grasses and grass like species Yucca spp. and Buchloe spp. performed best. Osteospermum fruticosum, Lavandula angustifolia, Rosmarinus officinalis, Phormium tenax, and Pennisetum setaceum had the best appearance of the herbaceous perennials tested. For the shrubs, Coprosma repens, Cistus purpureus, Dodonea viscosa, Eleagnus pungens, Baccharis pilularis, Ceanothus thysiflorus, Thuja orientalis, and Nerium oleander had the best appearance when irrigated with recycled water. The best annuals were Senecio cineraria, Antirrhinum majus, Primula spp., Viola spp., and Calendula officinalis. Of the groundcovers Heuchera spp., Lonicera japonica, Vinca major, Hedera helix, and Ceanothus griseus had the best results. From the experiment a list of tolerant and non-tolerant plants was compiled (Appendices 1 and 2). While many plants were capable of developing and growing normally, other plants were sensitive to recycled water irrigation. In order to prevent salt damage to plants and expand the use of recycled water, salt tolerance of landscape plant material must be identified (Niu et.al, 2006).

Pine bark (PB) has been the principal component of nursery crop substrates in the United States for more than 60 years. Substrate material used for the purpose of growing ornamental plants in the Great Plains is generally shipped a great distance, primarily from the Southeastern U.S., due to a lack of pine plantations in this region. Eastern redcedar (Juniperus virginiana L.; ERC), an aggressively weedy tree species, has been identified as a possible alternative to PB for nursery substrates. The objective of this thesis was to evaluate the establishment of Miscanthus sinensis N.J. ‘Little Kitten’ (dwarf maiden grass), Rosa (L.) ‘Radtkopink’ (Knockout® rose), Ilex glabra (L.) A. Gray ‘Compacta’ (holly), Ulmus parvifolia Jacq. ‘Emer II’ (Allee® lacebark elm), Sedum telphium L. ‘Autumn Joy’ (sedum), Hosta Tratt. ‘Sum and Substance’ (hosta), and Hemerocallis L. ‘Charles Johnston’ (daylily) in three substrate mixes. These substrate mixes consisted of 80% PB: 20% sand, 80% ERC: 20% sand, and 40% PB: 40% ERC: 20% sand. At the end of the production phase differences in growth were observed in maiden grass, holly, lacebark elm, and sedum. At the end of the landscape establishment phase, no differences in growth were observed in any species except holly and hosta. To attempt to overcome the sub-optimal physical properties of ERC (high air space and low container capacity), cyclic irrigation was used to evaluate growth of Sedum spectabile Boreau ‘Autumn Fire’ (sedum), Rudbeckia fulgida Aiton ‘Goldstrum’ (black-eyed susan), and Hibiscus moscheutos L. ‘Luna White’ (hibiscus) in the same 3 substrates. The objective of this study was to evaluate the affect of irrigation frequency (1x, 2x, 3x, or 6x per day) and substrate ERC content on plant growth. Sedum had the greatest growth index (GI) shoot dry weight in PB and when irrigated 1x and 2x per day had the greatest root dry weight regardless of substrate. Irrigation frequency had no significant difference for GI and shoot dry weight Black-eyed susan had the greatest GI and shoot dry weight when grown in PB. Irrigation frequency only had an impact on shoot dry weight of black-eyed susan; plants irrigated 1x, 2x, and 3x per day had the greatest growth. Hibiscus had greatest growth in PB: ERC mix. Irrigation frequency had no impact on growth of hibiscus. Cyclic irrigation does not overcome low water holding capacities in these three species. Overall, ERC can be used as a partial replacement to PB (up to 50%). However, further research evaluating effects of different fertility regimes on ERC substrate is warranted.

The relationship of building to site is the most fundamental aspect in the creation of architecture. As man is a product of nature and his environment the way in which he chooses to after that environment in the process of building reveals not only his attitude towards his physical surroundings, but his purpose and justification for dwelling there. Not all attitudes will be the same, just as purpose will vary from person to person and structure to structure.
Mario Botta has said, “The first step in the architectural act is taking possession of the site. It is a conscious act of transforming a unicum, an awareness that grounds the new intervention in the geography, history, and culture of a particular site. The architecture is the constriction of this site. There can be no indifference toward the site. It is the very territory of architecture as well as the primary condition determining the laws by which one must build.”
Within the scope of my project I hoped to define this awareness within myself, this conscious act of defining and creating architecture against a background that demands the site be recognized as a primary generator of architectural form and attitude.Master of Architecture

In 2005, turfgrass was estimated to cover approximately 20 million ha of urbanized land. That area is increasing with rapid urbanization, stressing the importance of water conservation in the lawn and landscape industry. Turfgrasses have been identified for replacement by presumably more water-efficient ornamental plant species to conserve water. However, research comparing drought resistance and evapotranspiration (ET) of turfgrasses with ornamental landscape plants is limited. Two studies were conducted to evaluate water use and performance under drought stress of several ornamental and turfgrass species. An online course was developed to educate students about critical water issues related to irrigation in urbanizing watersheds. In a field study, ET was measured using lysimeters and plant water status was evaluated under deficit irrigation (100%, 60%, and 20% ET) in Festuca arundinacea Schreb., Buchloe dactyloides (Nutt.) Engelm. ‘Sharps Improved’, and Ajuga reptans L. ‘Bronze Beauty’. Evapotranspiration was similar between A. reptans and F. arundinacea, and was 32 and 35% greater than ET of B. dactyloides. In a greenhouse study, the performance of one turfgrass (Poa pratensis L. ‘Apollo’) and eight landscape species (Achillea millifolium L., Ajuga reptans L. ‘Bronze Beauty’, Liriope muscari Decne., Pachysandra terminalis Siebold and Zucc., Sedum album L., Thymus serpyllum L., Vinca major L., and Vinca minor L.) was evaluated during a severe dry down and subsequent recovery. S. album, L. muscari, and P. terminalis performed the best, requiring 86 to 254 d to decline to a quality rating of one (1-9 scale: 1=dead/dormant, 9=best quality). The remaining species required 52 to 63 d. The only species to recover were P. pratensis [46% pot cover (PC) after 60 days], S. album (38% PC), and V. major (35% PC). A survey was developed to measure student learning as it relates to the level of sense and meaning present in the content of a new online course entitled “Water Issues in the Lawn and Landscape.” Survey results were compared with student learning as measured through a post-test. Post-test scores declined as the difference between sense and meaning increased (r =-0.82; P=0.03), indicating student learning is higher when both sense and meaning are present.

Full textAbstract:
Our understanding of the natural world is constantly evolving and strengthening as more observations are made and experiments are performed. For example, we understand that tree stems grow toward the light (positive phototropism; Darwin 1880, Loehle 1986, Christie et al. 2013) and against gravity (negative gravitropism; Knight 1806, Hashiguchi et al. 2013). We also know that plants respond to mechanical stimulus and perturbation (thigmotropism; Braam 2005). Genes and their resulting proteins have been described to uncover some of the mechanisms for these environmental responses, but relatively speaking, we have just scratched the surface (Wyatt et al. 2013). While the discovery of the molecular mechanisms responsible for these behaviors is certainly dependent on the ever-improving lab technology available, every molecular discovery is dependent on a macroscopic observation.
In this manuscript I present the two novel macroscopic observations I made on members of Araucaria in the urban forest. The first describes a hemisphere-dependent lean in A. columnaris, and the second provides genetic and morphological evidence that hybrids exist between A. columnaris and A. heterophylla.
Araucaria columnaris (J.R. Forst.) Hooker, or the Cook Pine is a conifer with a narrow native range that has been cultivated worldwide and grows unlike any other tree known. The initial observation we made was that trees in California and Hawaii lean south, and trees in California lean to a greater extent than trees in Hawaii. Measuring 250 trees in 16 regions worldwide, however, produced statistically significant evidence for a hemisphere dependent directional leaning pattern. Trees in the northern hemisphere lean south, and trees in the southern hemisphere lean north. Additionally, the lean becomes more pronounced at greater distances from the equator.
We also gathered morphological and genetic evidence in the California urban forest that A. columnaris and A. heterophylla (Salisb.) Franco are hybridizing. Many individuals have intermediate characteristics of both species, which originally led me to believe that hybrids exist in cultivation. After analyzing several individuals with microsatellite genetic markers, I have enough evidence to conclude that hybrids between A. columnaris and A. heterophylla exist. This is an important observation mainly for municipalities and arborists interested in properly identifying trees in the urban forest. Knowing the proper identity of trees is imperative to informing decisions about their protection or removal.
As we continue to ask questions about the inner workings of nature we will continue to gain a better appreciation for what we still do not know. The evidence provided in this manuscript better informs our future questions about a leaning pattern in A. columnaris and about the history of the cultivation of Araucaria.

The Midwest and southern Great Plains regions of the United States are known for historic and severe droughts. However, short-term recurring drought events are more common and can limit tree survival in landscape and production settings. The pressure of environmental stress combined with numerous diseases and pests are decimating existing Pinus L. spp. (pine) plantings and driving the effort to identify alternative species. Four species of conifer were grown in a pine bark substrate and subjected to recurring moderate to severe drought in a controlled environment glass greenhouse as well as field planted to observe root and shoot growth during the initial 12 months after transplant. The species utilized were Abies nordmanniana (nordmann fir), Cupressus arizonica (Arizona cypress), Picea engelmannii (engelmann spruce), and Thuja x ‘Green Giant’ (‘Green Giant’ arborvitae). Results indicate that C. arizonica exhibited extraordinary growth after establishment and was able to maintain growth and photosynthesis following several drought cycles. Thuja x ‘Green Giant’ exhibited significant increase in root and shoot growth after transplant. Under conditions of moderate and severe drought, only minimal reductions in height and shoot dry weight were observed while root growth and photosynthesis were unchanged. Abies nordmanniana experienced minimal increases in root and shoot growth throughout the growing season and was unaffected by drought. In contrast, P. engelmannii had only modest increases in root dry weight after transplant, while shoot growth was non-existent. Under conditions of severe drought, photosynthesis was reduced. Cupressus arizonica, a known drought tolerant species, with its ability to establish quickly and endure drought may have an advantage when establishing in harsh climates such as the Midwest and southern Great Plains. Thuja x ‘Green Giant’ is known to be a rapid grower, however, it established slowly during the current study and may require additional time before resuming rapid growth and maximum drought tolerance. Slow establishing species such as A. nordmanniana and P. engelmannii may require greater attention to season of planting to coincide with rapid root growth. However, P. engelmannii may not be a suitable choice for the Midwest due to the inability to maintain photosynthesis during periods of drought.

Full textAbstract:
My thesis research concerns Thomas Charles George Weston (1866-1935). Its principal
focus is his landscape vision for Australia's national capital in its founding days and his
innovative horticultural and arboricultural work in that vision's execution. Between 1913
and 1926 his work involved reversing, by afforestation planting and conservation measures,
the existing process of degradation of the site's landscape. He also achieved for the
new city a densely planted landscape using indigenous and exotic trees and shrubs.
Weston's pioneering work made a significant contribution to Canberra's contemporary
'city in the landscape' image.
Part of my research is about understanding the context of Weston's earlier professional
experiences in Britain and New South Wales in the period 1878 to 1912. A brief
insight into his personal life and career shows how the people he worked for, the skills he
acquired, and the type of landscapes he worked in shaped his approach to his landscape
activity at Canberra. Of particular note are the valuable influences of David Thomson
and Joseph Maiden, respected figures in botany and horticulture in Britain and Australia
respectively.
My research on Weston's achievements in Canberra demonstrates his technical and
professional thoroughness. I have documented all his work on a project-by-project basis
to provide accurate reference material for on-going professional practice and research.
His afforestation and conservation work from 1913 onwards and his urban planting in
the crucial 1921 to 1926 period reflects the depth of his training and skills and understanding
of landscape. Analyses of disputes between Weston and others including Walter
Burley Griffin demonstrate the soundness of his professional judgment.
I have concluded that Charles Weston had a clear vision of what he wanted to achieve,
the necessary skills and experience to achieve that vision and a thorough understanding
of the national capital site. He also possessed the necessary personal qualities to achieve
his vision which responded sensitively to the aspirations of Australians for their national
capital. Largely because of Weston Canberra will remain a highly significant step in the
development of Australian landscape architecture.

An analysis of the green industry of Virginia was completed in the year 2002 using a mail survey sent to industry participants. The survey was conducted by the Virginia Agricultural Statistics Service (VASS). This data was used to run an economic impact analysis of the industry using IMPLAN Professional software. Additionally, the software was used to determine the approximate affects of drought and water restrictions on the green industry. VASS received a total of 1,146 surveys for a response rate of approximately 27%. Of these responses, 42 surveys indicated that they plan to have future green industry sales but were not presently involved in the business. Another 525 responses claimed to be no longer actively involved in the industry. Therefore, the actual response rate was much closer to 15%. This necessitated the use of numerous alternative data sources to create a more complete model representation of the green industry as a whole. Two separate model scenarios were created, the first using purely survey response data, the second including data from additional sources and factoring out for possible double-counting errors. Direct employment generated from the industry was predicted to be between 29 and 36 thousand jobs, depending on which model scenario is consulted. The total economic impacts predicted from the different models are $2.03 billion and $2.41 billion, respectively. The analysis of the affects of drought and water restrictions predicted a decrease in overall impacts by 33% and 23%, respectively.Master of Science

Full textAbstract:
The flora of Crete in its multifarious micro-landscapes offers the possibility of selecting native species with high ornamental value for use in urban landscapes and commercial horticulture. To assess this potential eight species were selected: Staehelina petiolata, Ptilostemon chamaepence, Otanthus maritimus, Prasium majus, Convolvulus dorycnium, Campanula pelviformis, Sternbergia sicula and Colchicum macrophyllum. The biological cycle in situ, sexual and asexual propagation as well as their cultural requirements and adaptability in urban landscape were studied. In addition to identifying the light and temperature requirements for seed germination of the species, Other factors were important including after-ripening for P. chamaepence and S. petiolata, scarification for P. majus and C. dorycnium and imbibition in 20°C for C macrophyllum and S. sicula. Propagation by stem cuttings was influenced by mist, addition of IBA, the season and the substrates. IBA solutions at 4000, 2000 ppm and 2000 ppm in powder promoted on rooting of S. petiolata, P. chamaepence and P. majus stem tip cuttings with the highest rooting level of 50, 70 and 72%, respectively, while both IBA at 0 or 2000 ppm on Otanthus maritimus produced 100% rooting. Best substrates were peat-moss+vermiculite, vermiculite, sand and vermiculite and best seasons autumn, spring or late autumn, early summer, and spring for Staehelina. Ptilostemon, Otanthus and Prasium, respectively. Cross-cutting and BA on the base of Sternbergia sicula increased the bulblets from 1-3.5 to 12.8 and 13.5 per bulb yearly, respectively. Colchicum macrophyllum had a very low asexual reproductive activity producing one corn per year. The wounding of the replacement bud stimulated development of the reserve bud so that each corm could produce two or more cormlets. Morphogenesis was achieved in vitro by the affect of BA; callogenesis and rhizogenesis by NAA, and rhizogenesis by IBA on S. petiolata and P. chamaepence seedlings. Adventitious bulblets and plantlets formed on scales and clumps of shoots of S. sicula by the addition of BA and NAA producing over 20 bulblets per bulb. 2,4-D, BA, NAA and combinations produced callus, shoots and new corms on buds of C. macrophyllum. All studied species were established successfully in pots and in an urban landscape. The ornamental characteristics and use of eight species was determined and a master plan was designed using indigenous plants of Crete.

Urban environmental pollution continues to be exacerbated by a number of factors relating to human population growth including sewage discharged directly into the urban rivers designed with concrete-sealed riverfronts. This has left a number of rivers with deteriorated water quality. Where a riverfront could be the highlight and magnet of the city, it may instead become a stain and waste place. In 1969 American landscape planner McHarg proposed the landscape planning theory, “Design with Nature." His primary argument was that natural processes provide self-regulatory functions that need to be reflected in our plans and designs. Ecological design aims include restoring or promoting natural processes and automatic (bio-physical, regenerative, and adaptive) stabilizers. A wide range of scientific knowledge is available to help guide the designer, but designers usually have limited time to complete their designs. Unfortunately, much of this information is diffusely dispersed in research literature and not easily collected and synthesized by the design community. The purpose of this review is to help provide a synthesis of current thought and to help establish the basis for principles that can aid the designer, offering easy-to-understand design guidelines related to the use of aquatic plants in ecological redevelopment along urban riverfronts. This report focuses on using aquatic plants as the main material to help solve two key problems along riverfront developments: water pollution and flooding. As such this report can serve as a guide for the designer helping them to select aquatic plants using an ecological design approach for the redevelopment of urban riverfronts. It also addresses the essential need to adapt designs based on local site problems and requirements. Since this report provides a review and a basis for where to start in designing with aquatic plants in ecological redevelopment of urban waterfronts, it should not be considered as an exclusive source for the designer but rather a complement to local guidelines and information to derive design solutions.

Full textAbstract:
Since the mid-1800's the Philippi Horticultural Area (PHA) has been of agricultural significance to Cape Town, producing food for the city. The Area also forms part of the remnant floodplain, and is essential in maintaining the recharge of the Cape Flats Aquifer, an important water source for Cape Town. Conflicting land use agendas are the major threat to resources in the PHA. Besides agriculture, there is an increasing demand on the City of Cape Town to provide housing in close proximity to the city centre. In light of this, re-zoning land in the PHA is being considered. While rezoning will address the demand for housing, it will put even further pressure on the current natural systems and water resources, as well as the historic presence of agriculture in the PHA. A new approach is required using landscape-based urban design to tackle what would usually be a planning predicament. Densification and development could be viable if they do not impact or encroach on the natural systems and agricultural land in the area, but rather help to sustain them. This requires introducing development typologies that work within the existing landscape and reconfiguring urban form to facilitate positive interfaces with both natural and agricultural systems. This project investigates integrating land use and experimentation with landscape and urban morphology as design tools in reconciling agendas, securing the agricultural and water resources in the PHA. The structuring land uses utilised are the urban fabric, agricultural land, natural systems and public open space. These are explored through a combination of geo-spatial mapping, collages, and a series of typologies that interrogate land use relationships in the PHA. Experimentation at multiple scales was used, a smaller area being used as a prototype for the larger area. Property lines significantly inform the framework for development, with consolidation and subdivision being the main tools for intervention. The project will re-organise the PHA in a way that enables mutually supportive land-use relationships, to secure the natural resources and function of the PHA while facilitating necessary development.

Full textAbstract:
Water conservation in the Intermountain West will be an important issue in the future as population and demand for limited water resources increases. In Utah, outdoor water use accounts for up to 60% of total per capita water use with 67% of that outdoor water being used to irrigate non native plant species to maintain a uniform green appearance. The objective of this study was to measure intra landscape changes in soil water potential during a 21.5 day dry down from DOY 215 to 236.5 in the summer of 2005 and 2006. Four, 2 x 2 replicated traditional and drought tolerant landscapes were instrumented with inexpensive resistance blocks at four points and three depths (15, 45, and 90 cm) at the Utah Botanical Center, Kaysville, Utah. Each mixed vegetation landscape consisted of a drainage lysimeter planted with annual and perennial shrubs, bunch grasses, turf grasses, and a 1.5 m coniferous tree. Mean soil water potential varied significantly between landscape treatments (p 0.05).and was most negative at 15 cm at the end of the dry down under Kentucky bluegrass (Poa pratensis. L) (-428 ± 50 kPa). In contrast, Buffalograss (Buchloe dactyloides) was significantly more negative at 45 cm and 90 cm (-291 ± 50 kPa and -197 ± 50 kPa), respectively, compared to Kentucky bluegrass, suggesting greater soil water extraction by deeper roots. Mean soil water potentials were less negative under the shrub and conifer treatments compared to turfgrasses at the end of the dry down on DOY 236.5, suggesting lower plant water use and/or hydraulic redistribution.

Full textAbstract:
Herbaceous perennials are planted worldwide in public gardens, and commercial and home landscapes. Little research based information exists on response of herbaceous perennials to fertilizer nitrogen (FN) rate and timing and the potential for loss of applied N via leaching. Therefore, we constructed simulated landscapes and installed canna lily (Canna L. 'President'), coreopsis (Coreopsis verticillata L. 'Moonbeam' ), purple coneflower (Echinacea purpurea L. 'Magnus'), iris (Iris siberica L. 'Caesar?s Brother'), switchgrass (Panicum virgatum L. 'Shenandoah'), sedum (Sedum L. 'Herbstfreude'), and sage (Salvia x sylvestris L. 'East Friesland') to determine how FN rate and timing affected growth and performance of herbaceous perennials and potential N leaching. Porous ceramic cup lysimeters were installed in situ in each landscape plot 38 cm below the soil surface to examine the effects of FN rate and timing on soil solution N concentrations. The experiment was a 4 x 4 factorial in a randomized complete block design with four replications. Four rates of FN: 0, 7, 14, and 28 g?m-2 N were divided equally into two applications and applied at the following times: 1) winter (Jan. 15 and Feb.15), 2) spring (Apr. 15 and May 15), 3) summer (June 15 and July 15), or 4) fall (Sept. 15 and Oct.15) beginning 2001. Soil solution samples were collected approximately every 2 weeks from Jan. 30, 2002 to Nov. 3, 2003 and analyzed to determine soil N (NO3- and NH4+) concentrations. Data collected in 2002 and 2003 for each species included the following number of flowers, plant visual evaluations, growth index (GI), and top dry weight. In 2003, mineral nutrient concentration was determined for each species. Plant response to treatments varied in 2002 and 2003. Our results indicated that despite statistical significance differences, many differences were small and FN treatments had little impact on the growth and ornamental qualities of these species. However, applying no N may not advisable, as some perennials species did benefit from an FN application during a specific time. Soil N concentrations remained above 10 mg?L-1 for 110 days, 62 days, 52 days, and 192 days when applied during January/February, April/May, June/July, 2002 and September/October in 2001 respectively. In 2003, soil N concentrations from FN rates of 7 g?m-2 N (1.5 lbs?1000 ft-2) and 14 g?m-2 N (3.0 lbs?1000 ft-2) applied in January/February, June/July, April/May and September/October remained below 10 mg?L-1 until the end of the study (Oct. 14, 2003). Nitrogen concentrations increased to 19 mg?L-1, 38 mg?L-1, and 21 mg?L-1, after 28 g?m-2 N (6.0 lbs?1000 ft-2) was applied in January/February, April/May, and June/July, respectively. To cover the needs of a wide variety of perennial species that usually exists in one landscape as well as minimize N concentrations in the soil solutions, we recommend a low to moderate rate of FN (5 g?m-2 to 15 g?m-2 ) be applied in split applications in spring and early fall.

Full textAbstract:
Many plants are not commercially produced due to a lack of accessible information on their horticultural requirements and landscape potential. Members of the Legume Family (Leguminosae) are often conspicuous components of the vegetation of arid and semi-arid subtropical regions. Many of these plants are suitable for landscaping use in areas suited to their cultivation. Coursetia glandulosa, Erythrina flabelliformis, Eysenhardtia orthocarpa, Haematoxylon brasiletto, Lysiloma watsonii, Pithecellobium mexicanum, and Sophora arizonica are woody legumes native to the Sonoran Desert region which offer a variety of form, texture, color and function. All of these plants grow readily from scarified seed. E. flabelliformis and E. orthocarpa are easy to propagate from stem cuttings. Some irrigation is necessary for establishment and reasonable growth in the landscape. Maintenance and pests are minimal. Freezing temperatures are the primary limiting factor to several of the plants. S. arizonica is slow growing and is prone to rot in the nursery.

The recent growth of low-density urban developments in the Mediterranean coast has led to an increase in the number of private domestic gardens. This thesis examines the flora, features and management practices of 258 private gardens in the Alt Empordà region in Catalonia. We also calculated water requirements of gardens based on species composition and land cover, and determined whether they can be predicted from the socioeconomic, demographic and cultural characteristics of households. Of the 635 taxa identified, 68% were exotic. Moreover, 39 species have been considered potentially invasive in Spain, although only 25 were present within the limits of the adjacent Aiguamolls de l’Empordà Natural Park. The distribution of garden floras was significantly related to different socioeconomic and demographic gradients, such as the occupancy rate of the house, the origin of the residents, their income level and the percentage of unemployed members.L’augment recent dels espais urbans de baixa densitat a la costa mediterrània ha comportat un increment del nombre de jardins privats.

També es van calcular les necessitats hídriques dels jardins d’acord amb la seva composició i estructura vegetal, i es va determinar si es podien predir a partir de les característiques socioeconòmiques, demogràfiques i culturals de les llars. Dels 635 tàxons identificats, el 68% eren exòtics. A més, 39 espècies han estat considerades com a potencialment invasores a Espanya, encara que només 25 són presents dins dels límits del Parc Natural dels Aiguamolls de l’Empordà. La distribució de la flora del jardins es va relacionar significativament amb diferents gradients socioeconòmics i demogràfics, com ara la taxa d’ocupació, l’origen dels residents, el nivell d’ingressos o el percentatge de membres en atur.

ABSTRACT Issues on global warming and climate change have brought about the increasing attention to the importance of environmental greening and protection. The landscape and horticulture industry, which is considered the promoter of environmental greening, has been maturely developed in Taiwan yet encountering increasing challenges. Performing business transformation has become the key to business sustainability; however, very few studies have focused on the key success factors of the landscape and horticulture industry. Accordingly, the study explores key success factors of the business transformation of the landscape and horticulture industry and attempts to rank these factors based on their significance to the transformation process. To explore key success factors and the ranking, the study selects numbers of possible factors from previous research and professional suggestions and uses Analytic Hierarchy Process (AHP) to evaluate and analyze feedbacks from professionals and experts of landscape and horticulture industry in Taiwan. Research findings reveal that the top five key success factors of the transformation of the landscape and horticultural industry are market size, international economic trends, labor cost and human resources, market demand, and product or service differentiation. In the case of rapid changes in the internal and external environment, companies should grasp critical elements to strengthen their adaptability. This study proposes suggestions and expects to assist managers in landscape and horticultural industries to successfully undergo a business transformation.

The flower industry in Taiwan is very competitive among the world. With the gifted natural resources, we can plant outstanding flower products via proper cultivating devices. By the 30 years of development, there are more than 30 kinds of products which are selling abroad. Many ornamental flowers can be produced in a large extent by being planted with suitable cultivating devices. Except the farmers keep improving the technique of planting flowers, the government, such as the Council of Agriculture, Executive Yuan, is also positive on extending the flower industry. With the cooperation and effort of both the public and the government, the flower industry in Taiwan can not only fulfill the domestic requirement but also own the ability of cultivating species which have high economical value and are able to be sold abroad. Yet, with the lake of management, there are only less than 10 kinds of new products being released annually according to the statistics. We are now facing challenges on creativity and marketing. Comparing with Holland the South Africa, which separately releases 30 kinds of and 25 kinds of new flower products, the flower industry in Taiwan is low competitive globally. Accordingly, this research is aim at improving the global competitiveness of our flower industry through developing new flower species with proper techniques and devices. According to the researches, Freesia and the Baby's Breath are two of the most profitable export products among various kinds of flowers. With facilities gardening, we can control the time of the flowers' germination and blooming, accordingly, control the flower season and yield. Consequently, we can get the hugest profit.

Full textAbstract:
Throughout time nature has been a prescribed healer of stress on the human condition. Its vital integration into our daily lives has been proven by scientific evidence. The majority of Americans spend approximately 1/3 of their life working, whatever that job may entail. Therefore, it makes sense that the environments that we spend so much of our life in for work at extremely important to our physical and mental health, however, current workplace models are not acknowledging that. Redefining the workplace to integrate nature would start to change work life in this country and how work itself is viewed.
This thesis focuses on creating healthy and holistic production spaces for workers in areas like Western Massachusetts. Because this area shares urban and rural qualities while being primarily suburban of major Northeastern cities such as Boston and New York, it provides unique ground for a wide array of work occupations and work types. On a chosen site of Northampton, MA, a new work model will be developed around the exposure to nature integral to a collaborative co-op/ incubator space for small businesses in the area who need office and production spaces in a community setting.
The progression of this research will lead to a developed incubation space with a positive environmental impact. Precedent research of archetypes such as Michael Singer’s Alterra Atria, and Miller Hull’s Bullitt Center exemplify sustainable criteria in relation to office architecture. By using concepts underlying an even further integration with the community ideas from John Dinkeloo & Kevin Roche’s Ford Foundation Headquarters, Candilis, Josic and Woods’ Freie University Berlin and BIG & Heatherwick’s New Google Headquarters. By creating a building that addresses the diverse makeup of the larger community of Northampton, MA, this co-op space would become an example of how a workplace can work with nature towards a greater impact on the environment post-occupancy.

Gardens played a significant role in the lives of European peoples living in the thirteenth and fourteenth centuries. By producing texts in which gardens and other cultivated landscapes are used as symbol and setting, medieval writers provide us with the opportunity to gain insight into the sociocultural conventions associated with these spaces in the late medieval period. By building our understanding of medieval horticulture through an examination of historical texts, we position ourselves to achieve a greater understanding into the formation of contemporary cultivated literary landscapes and their attendant conventional codes. This study provides a map of current medieval garden interpretation, assessing the shape and validity of recent literary criticism of this field. With a focus on the hortus conclusus (the walled pleasure garden) and arboricultural spaces (including hunting and pleasure parks), this study provides an historicist reinterpretation of horticultural landscapes in Chaucer’s Troilus and Criseyde, Sir Orfeo, and Sir Gawain and the Green Knight, furthering our understanding of the authors’ use of such conventionally-coded spaces in these canonical romances.

Doutoramento em Arquitectura Paisagista - Instituto Superior de AgronomiaThe aim of this dissertation is to bridge the gap which existed in terms of our knowledge on parks ans gardens designed by landscape gardners from Porto, in the final decades of the 19th century and early decades of the 20th century, before the implementation of the teaching of Landscape Architecture in Portugal and the blooming of modernism in garden art. It has been organized and developed through the research and the review of the work of two horticulturists and landscape gardeners - Jeronymo Monteiro da Costa and Jacintho de Mattos - in the period between 1855 and 1938 - and through the characterization of the horticultural context in which their work as designers emerged and developed. The conclusion is that, given the quality, significance and expression of the parks and gardens designed by these landscape gardeners, they correspond to referential concepts in landscape art in Portugal, by following the formal typologies in vogue in Europe, by adjusting to the shift in conceptual paradigms and, up to a certain extent, by embracing models characteristic of the period which preceded modernism in garden art

The purpose of this study is to investigate the impact of using Minecraft to teach students garden landscape designs. This study adopted the quasi-experimental research method. There were two classes with a total of 68 twelveth grade students from a technical high school horticulture department in Taipei City. One class was asigned to be the experimental group and and the other the control group. The teaching intervention lasted for 14 sessions. The experimental group used creative mode in Minecraft to carry out garden landscape design teaching. The control group received the conventional teaching method. For data collection, a design pre-and post- test were administered, and students were asked to fill out the ARCS learning motivation scale. The results showed that there were no significant difference between the experimental and control group in their learning performance and learning motivation.

Full textAbstract:
At the turn of the twentieth century, apples served as a catalyst for far-reaching social and environmental change in the North American West. As people debated the future of North American society as a rural or urban civilization, rural advocates found their answer in horticulture. Steadfast in their conviction that urban environments were corrupt, immoral, and disordered, people on both sides of the international boundary engaged in a boisterous promotional campaign that culminated with the creation of an orcharding landscape that spanned British Columbia, Washington State, and Oregon. Consequently, countless communities found new purpose or came into existence organized around the cultivation of apples and other assorted fruits. Fully aware of negative stereotypes that depicted farming as backwards and unfulfilling, horticulturists argued that fruit farming would lead to the creation of a modern countryside. Guided by scientific agriculture, refined and intelligent settlers would transform rural life by uniting in partnership with “Dame Nature,” leading to bountiful harvests as nature was finished to its “intended end.” As a result, the orcharding landscape would organize an alternative modernity that stood in juxtaposition to the urban-industrial axis of development. Despite their location in different political projects, fruit farmers on either side of the International Boundary bore striking affinities that were affirmed and reinforced through publications, associations, exhibitions, and educational initiatives, underlining the significance of the border as a vantage to appreciate divisions as well as continuities. While the creation of a modern countryside was sustained by high hopes, growers did not anticipate that nature’s bounty would in many instances stand as a curse rather than a blessing. Through two world wars, growers wrestled with the changing contours of rural life, particularly as it related to rural growth. While orcharding endured, its original conception as the nucleus of a progressive and middle class rural society did not.
