Consequences of broadscale timber plantations for biodiversity in cleared forest landscapes of tropical and subtropical AustraliaBackgroundIn Australia, as in many countries, there has been a shift in timber production from native forests to plantations. While plantations are primarily considered an efficient means of producing timber, there is increasing interest in their potential contribution to biodiversity conservation. This paper conducts a literature review of the impacts of plantations on biodiversity and assesses plantation scenarios proposed for cleared rainforest landscapes in tropical and subtropical Australia.

Mapping Species Composition of Forests and Tree Plantations in Northeastern Costa Rica with an Integration of Hyperspectral and Multitemporal Landsat ImagerybackgroundThis article discusses the improvement in accuracy of remote sensing to monitor and evaluate reforestation projects by combining moderate-resolution and hyperspectral imagery with multi temporal, multispectral data. The combination of these technological monitoring methods allows researchers to accurately classify general forest types and tree plantations by species composition. Open access copy available |
Creating Woodland Islets to Reconcile Ecological Restoration, Conservation, and Agricultural Land UseBAckgroundThe paper recognizes that there exists an agriculture and conservation paradox - agriculture is frequently in conflict with the other environmental services that forests provide. Thus, the authors review existing approaches to woodland restoration and consider the use of the woodland islets approach. Open access copy available |
Mapping Priority Areas for Forest Landscape Restoration and Improvement of Rural Community Livelihoods in Guatemala's San Marcos HighlandsbackgroundThis study maps priority areas for forest landscape restoration in three watershades of south-western Guatemala. This rural region has received attention from local government and international socio-economic development projects. Research Goals & MethodsThis study used GIS and Multi-criteria decision analysis to generate maps. These tools enabled the integration of a wide variety of complex information to evaluate different contexts and dynamics of the landscape. Open access copy available |
The Political, Social, and Ecological Transformation of a LandscapeBackgroundIn 1951 the Chinese Government issued the Decision on Cultivating Rubber Trees, which resulted in the establishment of large-scale rubber plantations in the tropical regions of China, including Xishuangbanna in southern Yunnan. These rubber plantations, worked by relocated Han Chinese, were a manifestation of state power on the landscape. Open access copy available |
Forest Cover and Deforestation Patterns in the Northern Andes (Lake Maracaibo Basin): A Synoptic Assessment using MODIS and Landsat ImageryBackgroundSouth America has the highest deforestation rates in the tropics. Yet, the science is often questioned when determining these rates. For example, Venezuela, which has the second highest rate in the region, produces government reports on deforestation that are continually questioned by third parties. This paper stresses the need for more accurate and consistent data on forest cover and greenhouse gase emissions from deforestation. Available with subscription or purchase |
The Savannization of Moist Forests in the Sierra Nevada de Santa Marta, ColombiaBackgroundThis study in the Sierra Nevada de Santa Marta seeks to determine if savannas are natural or caused by anthropogenic factors. The authors use climate data from the past and present, the location of vegetation, and land use history to test their hypothesis. Available with subscription or purchase |
Facilitation of Forest Landscape Restoration on Abandoned Swidden Fallows in Laos using Mixed-Species Planting and Biochar ApplicationbackgroundThis article aims to assess the feasibility of a plantation with eight mixed native species fertilized with rice husk biochar as a technique for soil amendment at a specific site in Laos. Research Goals & MethodsThe use of biochar was compared to inorganic (NPK) fertilizer and to no fertilization. The effects on the planted seedlings establishment and growth were monitored for four years. Open access copy available |
Modelling the Effect of Forest Cover on Shallow Landslides at the River Basin ScalebackgroundThis study analyzes soil models that can be used to help predict soil erosion which are useful to prioritize reforestation areas of watersheds. Research Goals & MethodsThe researchers tested the models in a river basin in Ecuador. They collected data for soil moisture/matric potential, depth, and rainfall. Vegetation (overland flow resistance coefficient) and root cohesion data were derived from the literature, as was the evapotranspiration rate. Open access copy available |
Effect of Vegetation Restoration on Soil and Water Erosion and Nutrient Losses of a Severely Eroded Clayey Plinthudult in Southeastern ChinaBackgroundIn this study, researchers compare erosion from reforested and degraded sites in subtropical southeastern China. Goals & MethodsThe objective of the study was to estimate the long-term influences of reforestation on soil and water erosion and nutrient losses in regions of southeast China that are characterized by severely eroded bare land derived from Quaternary red clay. The study examined surface runoff, soil erosion, and soil nutrient content. Available with subscription or purchase |
