In China a substantial plantation industry involving 5.4 M ha of exotic eucalypts and up to 50 000 ha of exotic acacias, has been built on a foundation of collaborative R&D sponsored by both China and Australia over the past 40 years. Germplasm derived from some of the early collaboration still provides the majority of trees deployed in current eucalypt plantations in China. But, whilst the past 2 decades has been the best of times for plantation eucalypts in China, the past decade has simultaneously been the worst of times for plantation acacias. Improved plantation productivities achieve

Abstract We examined the worldwide literature on biodiversity in forest plantations for the indicator organism assessed, species composition (native versus exotic), tree species diversity, and appropriateness of the comparisons made. Fifty percent of the studies used invertebrates, 36% birds, 6% mammals, and 6% vascular plants as bioindicators. We found that 76% of the existing literature compares exotic plantation forests to native/natural forests, 9% of studies compare native plantations to native/natural forests, and 3% examine plantations to plantations.

Data were collected in summer and winter in a 15-year-old plantation of Pinus taeda, at Clouds Creek, north-eastern New South Wales. In summer, diversity and abundance of bird species declined over a distance of 900 m into the plantation. However, in winter this progressive decline in bird densities was limited to within the first 200 m of the plantation periphery. At greater distances into the plantation, the floristic and structural characteristics of the vegetation (including windrows) were of more importance than the proximity of the plantation edge in accounting for variations in the abun

Reduced biodiversity and high number of endemics characterize island ecosystems. Island natives and endemics are considered more vulnerable than continental species to exotic species invasions and habitat changes. The effect of replacing a native forest by an exotic wood plantation was studied on the assemblage of native and endemic ant species. The main hypothesis was that endemic and native ant species were more vulnerable to habitat changes than the exotic ant species. Nevertheless, it was found that native ants were more numerous and specious in both native and exotic plantations. Also, hi

Today, tree plantations play a crucial role in supplying wood and wood-based products. They supply almost half of global demand, as well as supporting a diversity of ecosystem services. In tropical and subtropical areas, where tree growth is optimum and large tracts of land are available, forest restoration is presented as one of the most effective strategies for climate change mitigation. For these reasons, large-scale tree plantations are being encouraged in Africa, Asia and Latin America.

This study compared carbon (C) and nitrogen (N) distribution at a stand level in an exotic Japanese cedar (Cryptomeria japonica D. Don) plantation and a natural Serrata oak (Quercus serrata Murray) stand growing under similar site conditions in South Korea. The aboveground biomass (stems, branches, and leaves) of 20 trees (10 of each species), the forest floor, and the mineral soils to a depth of 30 cm were sampled to determine C and N concentrations. Except in branches, C concentrations were significantly higher (p < 0.05) in the Japanese cedar plantation than in the Serrata oak stand, whe

The Valdivian temperate rainforest (VTR) is a biome on the South American continent with high endemism that has experienced an intensive land-cover change in recent decades due to the expansion of agriculture, plantations of introduced forests, and urban growth. Today, the biome hosts key parts of the country’s agricultural and forestry industries. Previous studies focused on quantifying native forest and plantation cover area and exotic forest plantation area, among others. However, the importance of mountain areas as refuge of native forest in Chile remains unexplored. The aim of this resear

Abstract. The classification of tree species by remote sensing is an important task with a broad range of applications, including forest management, environmental monitoring, and climate change studies. Hyperspectral imaging has proven to be a valuable tool for this classification. Additionally, deep learning techniques have obtained outstanding results in hyperspectral classification. In this study, we apply a neural network to the classification of aerial hyperspectral images of trees. The study was conducted at a research station in southern Chile with 32 tree species.

This article focuses on the development of plantation farming close to the Zimbabwe-Mozambique border and its effects on the Ndau people. Colonial incursions on the Zimbabwe/Mozambique border areas resulted in the development of estate farming in the Chimanimani/Chipinge region. European settlements in the borderland led to land expropriation by the colonial state and multi-national companies for estate farming. These estates ranged from natural and exotic forests, coffee, tea to sugarcane plantations. The majority of the plantations lie along the Zimbabwe/Mozambique border. The estates are va

Abstract Globally, urban ecosystems provide important green spaces for biodiversity conservation. Many exotic species are grown in tropical urban ecosystems, and their harmful effects on native species and pollinator communities have been widely documented. Therefore, the purpose of this research is to determine the origin (native or exotic to Indonesia, sexual and reproductive system) of tree species on the University of Sumatera’s (USU) campus. Field inventory methods were used in this study for observed tree species on the USU campus. All tree species were observed, their flowering observed

Urban parks are an important part of the city's green infrastructure and serve as an indicator for the city's natural environment. Six urban parks in Faisalabad were evaluated, split into two categories: Old parks (OP) and New parks (NP). A thorough census of tree populations was conducted in specified urban parks, and many parameters were studied. The composition of trees, species richness, and distribution of native and exotic trees were evaluated among two types of parks. Tree stem count was used to calculate the diversity benchmark (10/20/30) for tree inventories in selected urban parks. T

Abstract The potential productivity of native and exotic larch plantations in the northeastern United States and eastern Canada is summarized. Attainment of high productivity over short rotations depends on the application of silvicultural practices that differ from those that are commonly applied to other, more tolerant, northern conifers. Practices leading to the successful establishment and management of larch plantations are discussed. North. J. Appl. For. 4:18-20, Mar. 1987.

ABSTRACT The response of microbial functional diversity as well as its resistance to stress or disturbances caused by the introduction of an exotic tree species, Acacia holosericea, ectomycorrhized or not with Pisolithus albus, was examined. The results show that this ectomycorrhizal fungus promotes drastically the growth of this fast-growing tree species in field conditions after 7 years of plantation. Compared to the crop soil surrounding the A. holosericea plantation, this exotic tree species, associated or not with the ectomycorrhizal symbiont, induced strong modifications in soil microbia

Abstract A permanent test plantation consisting of a single provenance of Japanese larch and six provenances of European larch was established in central Wisconsin in the spring of 1982 by hand planting 2-0 stock grown from seed originating in Europe. A randomized complete block design with seven replications was used. Altogether 294 trees (6 trees/plot X *** plots/block x 7 replications) were installed in the test. After five growing seasons in the field, plantation survival was 98%. Nineteen percent of the trees had suffered bark damage by deer, and 22% had terminals clipped by grasshoppers.

Abstract Swiss needle cast (SNC), caused by Nothophaeocryptopus gaeumannii, is a foliage disease of Douglas-fir (Pseudotsuga menziesii), that reduces growth in native stands and exotic plantations worldwide. An outbreak of SNC began in coastal Oregon in the mid-1990s and has persisted since that time. Here we review the current state of knowledge after 24 years of research and monitoring, with a focus on Oregon, although the disease is significant in coastal Washington and has recently emerged in southwestern British Columbia.
