Abstract:
It is important to build a scientific and effective indicator system for the assessment and management of regional ecological construction. A theme-based and network coupled framework provides a useful approach to solve some problems in establishing indicator systems, such as lack of systematic study on indicators connotation and non-transparent processes of indicators selection. Based on the ecological construction practice in Fujian province, China, this paper (1) analyzed the main challenges of the ecological construction,implementation and development processes, summarized the currently main themes for ecological construction, and built a theme-based indicators framework; (2) established indicators selection criteria matrix and alternative indicators matrix by using network analysis method; (3) built a multi-objective selection model considering the economic cost, social effect and ecological integrity by genetic algorithm to quantitatively select operational indicators of ecological construction. Our study will contribute to deeply understanding the connotation and improving the science and validity of the ecological indicators system for ecological construction assessment and management applications.

Abstract:
Indicators can monitor ecological environment changes and help maintain ecological balance. Bioindicators are divided into animal, plant, and microbial indicators, of which animal and plant indicators have previously been the most researched, but microbial indicators have drawn attention recently owing to their high sensitivity to the environment and their potential for use in monitoring environmental changes. To date, reviews of studies of animals and plants as indicator species have frequently been conducted, but reviews of research on microorganisms as indicator species have been rare. In this review, we summarize and analyze studies using microorganisms as indicator species in a variety of ecosystems, such as forests, deserts, aquatic and plateau ecosystems, and artificial ecosystems, which are contained in wetlands, farmlands, and mining ecosystems. This review provides useful information for the further use of microorganisms as indicators to reflect the changes in different environmental ecosystems.

Abstract:
- The use of socio-economic indicators in the analysis of health outcomes is not straightforward because those conditions act in a mediated and indirect way through the adoption of life styles, the characteristics of job or the capabilities of utilizing the opportunity of wellbeing offered by the modern health systems. Validity analyses of the national deprivation index based on indicators derived from national Census are summarized. Spatial and temporal stability of the association between deprivation and mortality are reviewed and Italian examples presented. Mutual standardization bias and ecological fallacy when using census tract data are also illustrated with original data based on longitudinal census cohorts studies. Keywords: material deprivation, mortality, validity, ecological fallacy, epidemiology, ecological bias. Parole chiave: deprivazione materiale, mortalitÀ, validazione, distorsione ecologica, epidemiologia, bias ecologico.

Abstract:
The evidence of the effects of human mediated climate change is already evident in most ecosystems. The IPCC projects that there could be as much as a 4˚C increase in global average temperatures by the end of this century. In Mpumalanga the average temperature is projected to increase by as much as 2.8˚C, and annual precipitation levels by as much as 60 mm. Climate change, along with other human mediated factors such as land use changes and the over exploitation of natural resources, will lead to increasing pressures on biodiversity. Anthropogenic climate change will have significant impacts on biodiversity. These include impacts on distribution, abundance and ecological interactions. It is important to adopt biodiversity monitoring programs to understand the effects of anthropogenic climate change on the biota, which will enable best practice management and conservation of biodiversity. So far however, very few existing monitoring programs allow for the detection of climate change effects, as shown by the European project EuMon and the South African National Biodiversity Institute. In a cost-constrained world, the efficient use of resources for conservation has become crucial in ensuring the success of mitigating the effects of global change. Two methods of identifying indicators for the assessment of the effects of climate change on biodiversity were developed. The first method included the development of a pragmatic approach to the identification of suitable indicators and was tested in the Mpumalanga province. This approach identifies suitable species and ecosystem indicators, by subjecting candidate indicator candidates through a series of filters. The second method used a combination of climate and biodiversity data to identify indicators in areas of greatest and least climatic change within the Mpumalanga province. It is recommended that a combination of both methods be used, in order to be most useful in informing current and future monitoring programs.

L'objectiu d'aquesta tesi és contribuir a l'ús dels peixos continentals com a indicadors de l'estat ecològic a la conca Mediterrània. En el primer treball es va detectar que encara que tots els índex biològics estaven correlacionats significativament, els peixos integren i expressen els estressos de manera i a una escala diferents, aportant una informació complementària als altres índexs. Al segon article es van estudiar els cabals de sis conques catalanes. S'ha mostrat que els règims hídrics estan alterats amb una tendència a la disminució del cabal i del nivell dels aqüífers. S'ha detectat quatre mètriques de peixos que es troben significativament afectades en zones més castigades per manca d'aigua degut a l'activitat humana. Es discuteix la necessitat de conèixer en profunditat el règim hídric de cada conca abans d'utilitzar els índex biològics. Al tercer article es va detectar que la composició d'espècies capturades va variar significativament al llarg del buidat amb un augment de l'alburn (A. alburnus) a les aigües pelàgiques durant els dies de pitjor qualitat de l'aigua, confirmant que l'alburn és més tolerant a la mala qualitat de l'aigua que la madrilleta vera (R. rutilus) i suggereix el seu potencial com a bioindicador. La condició d'aquestes dues espècies va canviar significativament al llarg del buidat de manera molt estreta amb la qualitat de l'aigua. Al quart capítol es va estudiar la biologia dels peixos d'un embassament altament contaminat (Flix). El percentatge de DELT anomalies i la presència de paràsits externs era major en la zona impactada que als punts de control i els valors més alts de pes eviscerat i pes del fetge estaven als punts de control. Les respostes van ser diferents per cada espècie i la carpa va ser la que va mostrar més clarament els impactes.

The aim of this thesis is to contribute to the use of freshwater fish as ecological indicators in the Mediterranean basin. In the first article we found that although most biological indices were correlated, fish reflected different ecological aspects due to their particular features. In the second article the stream flow regimes of six Mediterranean basins were studied. A decrease of streamflow and aquifer levels was detected, despite no observed decrease of rainfall precipitation. Of the thirty metrics tested to detect sites impacted by water abstraction, we detected four significant fish metrics. Furthermore, the role of biotic indices when the river is artificially dry is discussed. In the third article we found that species composition in the pelagic zone varied significantly during the drawdown with higher proportion of bleak (A. alburnus) during the days of worst water quality, confirming that bleak is more tolerant than roach (R. rutilus) to poor water quality. The weight-length relationship of roach and bleak also varied significantly during the drawdown with close relationship between water quality and fish condition. In the fourth article the condition and fecundity of freshwater fishes were assessed in a highly polluted reservoir (Flix reservoir). We have shown significant increases of DELT anomalies and ectoparasite prevalences and decreases in condition and fecundity of several freshwater fish at the impacted area. The responses to the pollutants were species-specific and common carp was the species that showed more markedly the effects.

Abstract:
As concerns mount about the impact of human activities on the biosphere, cities are in the frontline of initiatives to change the course of human society onto a more sustainable path. This thesis seeks to make clear the foundations of the concept of Cities as Sustainable Ecosystems, and to develop a set of indicators to chart a more sustainable course. To achieve this, the concept of sustainabllity; the characteristics and strategies of sustainable ecosystems and sustainable societal-ecological systems; the dynamics of current cities; and a range of indicator approaches, were investigated through a review of literature, including texts, journals and online resources. From this a sustainability assessment tool was devised to apply the ideas and indicators at a subdivision level, and it was used in two case studies of new urban developments in Perth, Western Australia. The concept of Cities as Sustainable Ecosystems offers the opportunity to integrate various sources of wisdom to provide guidance in rebuilding connections between people, between people and place, and in designing integrated systems, based on the characteristics and strategies of sustainable systems. A major conclusion of this research is that cities need to be viewed as part of their bioregions, and their ecological footprints need to match their bioregions. Indicators provide feedback about progress towards sustainability. They are most powerful when they are devised by communities working with experts. Crucial too is the visibility of ecological processes in cities as well as linkages to the bioregion, providing immediate and tangible indicators feedback to complement quantitative indicators. Response indicators such as the degree of civic participation provide some of the strongest signs of future improvements or decline. The sustainability assessment tool represents an attempt to provide a systemic approach to the assessment of urban developments, and to identify issues that need to be considered in the design.

Abstract:
More than 270,000 km of rivers and streams are impaired due to fecal pathogens, creating an economic and public health burden. Fecal indicator organisms such as Escherichia coli are used to determine if surface waters are pathogen impaired, but they fail to identify human health risks, provide source information, or have unique fate and transport processes. Statistical and machine learning models can be used to overcome some of these weaknesses, including identifying ecological mechanisms influencing fecal pollution. In this study, canonical correlation analysis (CCorA) was performed to select parameters for the machine learning model, Maxent, to identify how chemical and microbial parameters can predict E. coli impairment and F+-somatic bacteriophage detections. Models were validated using a bootstrapping cross-validation. Three suites of models were developed; initial models using all parameters, models using parameters identified in CCorA, and optimized models after further sensitivity analysis. Canonical correlation analysis reduced the number of parameters needed to achieve the same degree of accuracy in the initial E. coli model (84.7%), and sensitivity analysis improved accuracy to 86.1%. Bacteriophage model accuracies were 79.2, 70.8, and 69.4% for the initial, CCorA, and optimized models, respectively; this suggests complex ecological interactions of bacteriophages are not captured by CCorA. Results indicate distinct ecological drivers of impairment depending on the fecal indicator organism used. Escherichia coli impairment is driven by increased hardness and microbial activity, whereas bacteriophage detection is inhibited by high levels of coliforms in sediment. Both indicators were influenced by organic pollution and phosphorus limitation.

Abstract:
A broad range of environmental indicators were evaluated to determine their suitability for describing the early onset of nutrient enrichment in south-west Australian estuaries. The southwest of Australia experiences a Mediterranean climate with hot dry summers and cool wet winters. Most of the south-west estuarine catchments have been extensively cleared for agricultural and urban development and have been loosing unacceptably high loads of nutrients. Symptoms of nutrient enrichment have been observed in many south-west estuaries. An evaluation of fifty years of historical water quality data defined the range of normal behaviour for these systems together with the nature of rarer extreme events. It was found that south-west Australian estuaries are highly variable in space and time and appear to be more susceptible to nutrient enrichment than those observed elsewhere in Australia. While there may be significant fluctuations in physico-chemical conditions and the structure of biological communities in ecosystems subjected to natural variability and anthropogenic stressors, it is possible that the junction of biological communities in these situations is less affected by these types of perturbations. Several indicators of biological function (rates and processes) were developed and evaluated to determine whether they offered a greater degree of diagnostic precision (early warning) than measures of stocks and status (inventory). In evaluating various environmental indicators, it was found that no single indicator was able to unambiguously define the interactions between physic-chemical and biological processes and the response of these systems to anthropogenic and natural stressors. It has been concluded that a broad range of potential indicators must be evaluated simultaneously, in order to define baseline conditions, measurement endpoints and trends to inform catchment and estuarine management and restoration. Increased confidence in the selected indicator suite can flow from an evaluation of the monotonicity of correlated indicators, especially when assessments show consistent patterns for physico-chemical measures and measures of biotic community structure across several trophic groups. Traditional physic-chemical indicators have provided reliable information in me past, but problems have arisen when relating these measures to biological endpoints, particularly for estuaries with significant seasonal and inter-annual variability. In the absence of biological data for estuarine ecosystems experiencing significant seasonal and inter-annual variability, socio--economic indicators of catchment land use practices may be the only option. Paleolimnological investigations may also provide additional insight into patterns of natural variability over the longer term, but the degree of taxonomic resolution required and requirements for supporting stable isotope analysis, may consume considerable resources. Autotrophic protistans (periphyton, phytoplankton), appear to be useful for describing nutrient enrichment, salinity and other physico-chemical conditions, but complicating factors such as the nature of coupling of secondary predation need to be identified. Autecology of local indicator species also needs to be defined. Zooplankton appear to be limited as environmental indicators, but because of their potential role in grazing and materials transfer, they may be useful as elements of biotic indices across several trophic groups. One of the major impediments to using planktonic organisms for inferring the condition of estuarine health is the considerable vertical, horizontal and temporal heterogeneity displayed by these organisms in both disturbed and undisturbed systems. More recently, benthic macro-invertebrates have been successfully used to describe the nature and magnitude of organic enrichment of estuaries. Community structure, biomass and relative abundance of functional groups and indicator species have also been developed and used as environmental indicators. Problems may occur in the use of these organisms to infer health in south-west estuaries because of the presence of naturally immature communities and variable colonization dynamics where there is significant seasonal and inter-annual variability. Inventory measures of community structure have problems because of a lack of information about exchange pathways connecting system components and unknown interactions between diversity, stability and resilience of the ecosystem. Species richness, diversity indices and measures of biomass have probably been the most widely used indicators in the majority of published works, but generally without appropriate critical analysis of their utility. Biomass appears to have less inter-annual variability than do other measures of community structure. A myriad of biotic indices (ratios of functional groups) within and across trophic levels have been described in the international literature. There are problems in defining weightings and concordance methods for elements contributing to biotic indices and the loss of valuable information during these types of data reduction limit their potential. Detailed autecology of members of functional groups are required for biotic indices and this type of information is potentially available for some cosmopolitan species, but generally lacking for endemic species which may describe important nuances of the local environment. As with biotic indices, there is a range of combined metrics described in the literature. Metrics generally combine physico-chemical elements, and may include some biological information. Many of the problems with biotic indices apply equally to metrics, but when calibrated for a particular local situation, they offer considerable discriminatory power. Assessment of early colonisation dynamics and the responsiveness of periphyton communities to nutrient additions provided insights into some key processes in south-west estuaries. Periphyton communities in estuaries with a past history of nutrient enrichment responded well to nutrient additions while communities in less disturbed estuaries did not respond as readily. This infers that opportunistic species able to respond rapidly to nutrient additions may become established in estuaries having a nutrient enrichment history while they may be less able to maintain a viable presence in less enriched estuaries. While showing promise, additional testing and refinement of these process indicators would better define their potential as early warning indicators of nutrient enrichment for south-west estuaries. For describing the ecological health of south-west Australian estuaries, physico-chemical indicators of catchment and estuarine water quality and socio-economic measures of catchment land use history may be of use. If assumptions about the linearity of interactions between the diversity of biotic communities and the stability and resilience of ecosystem function are valid, then conventional measures of community structure will also provide useful insights. The ongoing selection, evaluation and refinement of environmental indicators for assessing the ecological health of south-west Australian estuaries, needs to proceed as a close partnership between land and waterway managers and scientific specialists.

Abstract:
No contexto da aplicação da Directiva-Quadro da Água, a ictiofauna é considerada como um relevante elemento biológico. Pela primeira vez foi desenvolvido um sistema de classificação para avaliação do estado ecológico dos ecossistemas aquáticos em Portugal, apesar dos constrangimentos impostos pela variedade e ubiquidade das pressões humanas e pelas peculiaridades dos agrupamentos piscícolas. Foram definidos grupos piscícolas para posterior estabelecimento de uma tipologia nacional de rios, foram seleccionadas métricas responsivas ás pressões humanas e foi desenvolvido um índice biótico piscícola. Os resultados evidenciam a necessidade de diferenciar correctamente a resposta da ictiofauna ás perturbações naturais e antropogénicas, considerando quer a variabilidade espacial, quer temporal dos agrupamentos piscícolas, típica dos cursos de tipo Mediterrânico. O uso de solo tem fortes consequências na degradação dos rios e na integridade da ictiofauna, sendo importante que a avaliação dos impactos considere a interacção entre diferentes pressões. A compreensão da influência relativa dos factores ambientais e humanos na ocorrência e abundância das espécies não nativas permitiu evidenciar o potencial papel das mesmas como indicadores biológicos. Esta tese contribuiu para o desenvolvimento e aperfeiçoamento de ferramentas de avaliação ecológica em Portugal, permitindo igualmente um aumento do conhecimento sobre a ecologia das comunidades piscícolas e funcionamento dos ecossistemas em rios de tipo Mediterrânico, com vista à sua conservação e reabilitação; ABSTRACT:Under the implementation of the Water Framework Directive fish fauna is considered a useful biological element. For the first time a Portuguese classification system to assess the ecological status of aquatic ecosystems was established, despite several constrains posed by the variety and ubiquity of human pressures and by the peculiarities of the fish assemblages. It was possible to define fish-based geographical groups for the subsequent establishment of a national river typology, to select metrics responsive to human pressures and to develop a fish biotic index. Results underline the needs for accurately differentiate between fish responses to natural and anthropogenic disturbances by accounting for the spatial and temporal variability of fish assemblages. Land use may lead to strong impacts on stream degradation and fish assemblages integrity and this evaluation must consider the interaction of different pressures. Understanding the influence of environmental and human factors in the occurrence and abundance of non-native species enlightened their role as a reliable tool in the ecological assessment of rivers. This thesis represents an important contribution to improve the ecological assessment tools in Portugal, while increasing knowledge on the ecology of fish communities and ecosystem functioning in Mediterranean climate rivers in view of their urgent conservation.

Full text
Abstract:
Passing sediment from reservoirs to downstream channels is a potential solution to aging infrastructure and reservoir storage capacity loss, which is a pressing challenge nationwide. The US Army Corps of Engineers (USACE) sediment management actions at reservoirs such as flushing may drive ecological changes that may be beneficial or detrimental to downstream ecosystems. However, these potential effects are currently not well understood or documented. An exploratory study of the potential ecological effects of releasing sediment downstream from reservoirs is presented in this technical note (TN). We focus on Tuttle Creek Reservoir in Kansas and use fish species as indicators of ecological change. A literature review of Kansas fishes was conducted and three conceptual models illustrating potential benefits or negative effects of releasing sediment downstream of Tuttle Creek Reservoir was developed. Some fish species may benefit from sediment releases, while others may be negatively affected. Further research and tools are needed to develop a greater understanding of these effects.

Technical Report on Assembling Indicators to Monitor Climate-Driven Change in Northeastern Forests. Forest Ecosystem Monitoring Cooperative, September 2021. http://dx.doi.org/10.18125/99o4tq.

Full text
Abstract:
Forest ecosystems are experiencing the impacts of climate change in many forms, however, comprehensive monitoring efforts are not always available to identify changing baselines. In order to improve our understanding of the impacts of climate change on ecosystem processes, the FEMC developed the Forest Impacts of Climate Change: Monitoring Indicators tool (Version 1.0). The Forest Impacts of Climate Change: Monitoring Indicators tool was developed for use by researchers and professionals to be able to easily access protocols used to monitor high priority indicators of the impacts of climate change in New England and New York. The monitoring protocols provide information for landowners and managers to implement their own monitoring programs that will be comparable to other studies being conducted across the region. By centralizing information about this network of monitoring sites, more data will become available to the community to help discern how forest ecosystems are changing. This report describes the methods and implementation used to build this tool. To develop the Forest Impacts of Climate Change: Monitoring Indicators tool, FEMC formed a committee of partners to select indicators and provide guidance about the literature review and eventual tool. The committee identified four ecological categories as important for monitoring climate change in the Northeast: Wildlife, Forest Systems, Trees, and Aquatic Systems. FEMC identified who is currently conducting monitoring efforts, what monitoring protocols are available for replication, gaps in monitoring data, and how we can make data and monitoring information easily available so that land managers can have the most up-to -date information possible. The developed tool compiles over 350 studies across 24 different indicators of the impacts of climate change. Through a filterable webtool users can find these studies, as well as 168 replicable protocols to direct implementation. The tool helps to identify gaps in monitoring efforts and provides a platform for users to contribute to regionally cohesive datasets. Monitoring of indicators across systems is critical for tracking and understanding climate change impacts. The Forest Impacts of Climate Change: Monitoring Indicators tool, developed for use by researchers, professionals, and land managers across the region, lets users find methods and protocols for monitoring climate change impacts and see where these monitoring efforts are already being conducted in our region. In addition, you can quickly visualize where there are gaps in our monitoring. As contributors in the Cooperative region share more information about their own monitoring efforts, this will become available to the community through this tool, increasing our ability to track and identify change in our forested ecosystems.

Abstract:
The study of taxonomic composition and ecological characteristics of wood species on devastated lands as a theoretical basis for the phytomelioration of environment remains relevant nowadays. It was discovered 32 species, 25 genera and 15 families in the course of the analysis of woody plant community from devastated lands of Petrovsky waste rock dumps. Among them, allochthonous species (59.38%) have an advantage over autochthonous (40.63%) according to the quantitative indicators. It was established, hemiapophytes predominate among apophytesspecies andneophytes predominate among anthropophytesaccording to the time of entry, according to the method of invasion ergasiophytes, according to the degree of adaptation ergasiophytes and agriophytes. The results of our analysis indicate that the investigated woody plant communitycorresponds to the conditions of localization.

Abstract:
In our time, a very urgent problem is the cessation of negative impacts on the environment and the return to the practical use of the territories of devastated lands. In this regard, it is important to find out the basic laws of primary soil formation in the area of these man-made neoplasms. The initial soil formation conditions were analyzed on 19 experimental sites which represent the main varieties of devastated land in the Kryvyi Rih Iron Mining and Metallurgical District (Central Ukraine): (i) waste rock dumps of old iron mines (old name “Forges”), (ii) tailing storage facility of underground iron mines, (iii) waste rock dumps of the Iron Ore Mining and Dressing Plant, (iv) waste rock dumps of the Granite Quarry Plant. It was established that on the devastated lands in Kryvyi Rih District, the initial soil formation occurs in very difficult conditions. Therefore, over 25- 100 years only very primitive soils were formed. The following features are inherent to them: (1) primitive soil profile (thickness 10-100 mm), (2) low levels of soil organic substance content (9.5-11.5 %), (3) alkaline indicators of the soil solution (pHH2O – 8.08-8.92, pHKCl – 7.42-8.23), (4) low levels of cation exchange capacity (6.34-8.47 mMol /100 g). By results of correlation calculations, among the factors of soil formation time (duration of soil formation) and input of plant ash elements’ fall are characterized by the maximum number of statistically significant correlation coefficients and their numerical values. In terms of chemical composition of the technosol, the values of organic matter content and exchangeable acidity (pHKCl) were the most predictable soil formation factors. Generally physical / chemical characteristics of geological rocks (as parent material) and time were the two most important factors in determining the initial pedogenesis on devastated lands in the Kryvyi Rih Iron Mining & Metallurgical District (Ukraine).

Full text
Abstract:
Breeding colonies of wading birds (orders Ciconiiformes, Pelecaniformes) and seabirds (orders Suliformes, Pelecaniformes) serve as important indicators of aquatic ecosystem health, as they respond to changes in food abundance and quality, contaminants, invasive species, and disturbance. The Comprehensive Everglades Restoration Plan, Restoration Coordination & Verification program (CERP-RECOVER) has identified wading-bird colonies as an important ecosystem restoration indicator. The National Park Service South Florida/Caribbean Inventory & Monitoring Network (SFCN) ranked colonial nesting birds eighth out of 44 vital signs of park natural resource conditions for ecological significance and feasibility. However, while large-scale monitoring efforts are occurring in the rest of the Greater Everglades Ecosystem, only minimal historic data collection and no extensive ongoing monitoring of wading bird and seabird nesting have occurred in Biscayne National Park. Consequently, due to their high importance as biological indicators and because they are a gap occurring in regional monitoring efforts, the network has initiated a monitoring program of colonial nesting birds in Biscayne National Park. This protocol provides the rationale, approach, and detailed Standard Operating Procedures for annual colonial bird monitoring within and close to Biscayne National Park and conforms to the Oakley et al. (2003) guidelines for National Park Service long-term monitoring protocols. The specific objectives of this monitoring program are to determine status and long-term trends in: Numbers and locations of active colonies of colonial nesting birds with a special focus on Double-crested Cormorants, Great Egrets, Great White Herons, Great Blue Herons, White Ibises, and Roseate Spoonbills. Annual peak active nest counts of colonial nesting birds in Biscayne National Park with a special focus on the species mentioned above. An annual nesting index (i.e., sum of monthly nest counts) with a special focus on the species mentioned above. Timing of peak nest counts for the focal species.

Full text
Abstract:
The Heartland Inventory and Monitoring Network monitors plant communities at Tallgrass Prairie National Preserve and evaluates a variety of environmental variables that affect vegetation patterns, including climate and ecological disturbances such as fire and grazing. Here we report on 2002–2018 trends in management actions (fire and grazing) and key plant community indicators. Temperature has increased over the past 50 years in the region. Precipitation and a standardized precipitation-evapotranspiration index included a high degree of interannual variability and did not demonstrate directional change. We documented a decline in disturbance intensity (i.e., less frequent prescribed fire and lower stocking rates) since 2006. A preserve goal is to maintain 30 to 60% of the area as bare ground (soil and rock) for ideal greater prairie-chicken habitat. Bare areas have been in decline and minimally meet the goal preserve wide. Bare areas vary by pasture and year, with bare areas exceeding the threshold in earlier years and Big Pasture and Red House Pasture falling short in some recent years. Although the preserve-scale mean minimally met the objective, there was a great deal of heterogeneity across monitoring sites. Litter cover and depth were greater than ecological recommendations for the greater prairie-chicken, especially in 2018. Litter depth demonstrated a great deal of variability and included deep litter. Woody plants were targeted to remain below 5% cover. Preserve- and pasture-scale cover means were well below this threshold but are increasing. Species richness on a per site basis (alpha diversity) and preserve-wide richness (gamma diversity) showed no apparent directional change when corrected for differences in sample size. Comparison of native species composition between 2002 and 2018 revealed a 36.9% difference in the Sørensen Index, although observer error accounted for almost 2/3 of this apparent change. The preserve continues to have characteristic tallgrass prairie species, and nonnative species continue to be low. Similar to targeted invasive plant monitoring, we found the target species Kentucky bluegrass to be below park thresholds. Continued evaluation of fire frequency and grazing intensity will be critical to achieving ecological goals including conserving the greater prairie-chicken. Development of a grazing plan may assist with prescribing stocking rates that are consistent with the preserve’s ecological and cultural objectives and could include alternative herbivores, such as goats or expansion of bison.

Full text
Abstract:
Natural Resource Condition Assessments (NRCAs) evaluate current conditions of natural resources and resource indicators in national park units (parks). NRCAs are meant to complement—not replace—traditional issue- and threat-based resource assessments. NRCAs employ a multi-disciplinary, hierarchical framework within which reference conditions for natural resource indicators are developed for comparison against current conditions. NRCAs do not set management targets for study indicators, and reference conditions are not necessarily ideal or target conditions. The goal of a NRCA is to deliver science-based information that will assist park managers in their efforts to describe and quantify a park’s desired resource conditions and management targets, and inform management practices related to natural resource stewardship. The resources and indicators emphasized in a given NRCA depend on the park’s resource setting, status of resource stewardship planning and science in identifying high-priority indicators, and availability of data and expertise to assess current conditions for a variety of potential study resources and indicators. Puʻuhonua o Hōnaunau National Historical Park (hereafter Puʻuhonua o Hōnaunau NHP) encompasses 1.7 km2 (0.7 mi2) at the base of the Mauna Loa Volcano on the Kona coast of the island of Hawaiʻi. The Kona coast of Hawaiʻi Island is characterized by calm winds that increase in the late morning to evening hours, especially in the summer when there is also a high frequency of late afternoon or early evening showers. The climate is mild, with mean high temperature of 26.2° C (79.2° F) and a mean low temperature of 16.6° C (61.9° F) and receiving on average 66 cm (26 in) of rainfall per year. The Kona coast is the only region in Hawaiʻi where more precipitation falls in the summer than in the winter. There is limited surface water runoff or stream development at Puʻuhonua o Hōnaunau NHP due to the relatively recent lava flows (less than 1,500 years old) overlaying much of the park. Kiʻilae Stream is the only watercourse within the park. Kiʻilae Stream is ephemeral, with occasional flows and a poorly characterized channel within the park. A stream gauge was located uphill from the park, but no measurements have been taken since 1982. Floods in Kiʻilae Stream do occur, resulting in transport of fluvial sediment to the ocean, but there are no data documenting this phenomenon. There are a small number of naturally occurring anchialine pools occupying cracks and small depressions in the lava flows, including the Royal Fishponds; an anchialine pool modified for the purpose of holding fish. Although the park’s legal boundaries end at the high tide mark, the sense of place, story, and visitor experience would be completely different without the marine waters adjacent to the park. Six resource elements were chosen for evaluation: air and night sky, water-related processes, terrestrial vegetation, vertebrates, anchialine pools, and marine resources. Resource conditions were determined through reviewing existing literature, meta-analysis, and where appropriate, analysis of unpublished short- and long-term datasets. However, in a number of cases, data were unavailable or insufficient to either establish a quantitative reference condition or conduct a formal statistical comparison of the status of a resource within the park to a quantitative reference condition. In those cases, data gaps are noted, and comparisons were made based on qualitative descriptions. Overall, the condition of natural resources within Puʻuhonua o Hōnaunau NHP reflects the surrounding landscape. The coastal lands immediately surrounding Puʻuhonua o Hōnaunau NHP are zoned for conservation, while adjacent lands away from the coast are agricultural. The condition of most natural resources at Puʻuhonua o Hōnaunau NHP reflect the overall condition of ecological communities on the west Hawai‘i coast. Although little of the park’s vegetation...
