Live Fences and Landscape Connectivity in a Neotropical Agricultural LandscapeBackgroundThis article describes the role and importance of live fences in the tropical regions of Central America. The study site covered an area of 4483ha and is located in a wet tropical forest zone in the Province of Heredia, Costa Rica. The landscape is dominated by cattle pasture and possesses a small, fragmented and homogenous structure with small patches of forests. Open access copy available |
Indigenous Fruit Trees of Madagascar: Potential Components of Agroforestry Systems to Improve Human Nutrition and Restore Biological DiversitybackgroundThis study focuses on three sites in the humid forest of Eastern Madagascar, namely Masoala, Andasibe and Ranomafana. Research Goals & MethodsA total of 150 wild fruit tree species from 82 genera and 42 families were identified through interviews with the local populations, from which a further 26 indigenous and exotic fruit species were shortlisted based on taste, nutritional value, income generation potential, diversification from currently planted species and biodiversity protection.

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 Fragmentation and its Correlation to Human Land Use Change in the State of Selangor, Peninsular MalaysiaBackgroundThis paper uses a simple fragmentation index comprising three landscape metrics- non-forest area, forest edge bordered by human land use, and patch size coefficient of variation- to study changes in forest fragmentation in the state of Selangor, in peninsular Malaysia between 1966, 1981 and 1995. Research Goals & MethodsThe study utilized digitized land use maps developed by the Soil Management Division of the Department of Agriculture, Malaysia, to study changes in land use over time.

Land Cover Change in Colombia: Surprising Forest Recovery Trends between 2001 and 2010backgroundThis study mapped annual land-use and land-cover from 2001 to 2010 in Colombia using MODIS (250 m) products coupled with reference data from high spatial resolution imagery (QuickBird) in Google Earth. Research Goals & MethodsThe authors evaluated land cover change at four spatial scales: country, biome, ecoregion, and municipality. Open access copy available |
Sixty-Seven Years of Land-Use Change in Southern Costa RicaBackgroundHabitat loss and fragmentation of forests are among the biggest threats to biodiversity and associated ecosystem services in tropical landscapes. This paper uses the vicinity of the Las Cruces Biological Station in southern Costa Rica as a regional case study to comment on seven decades of land-use change in one of the most intensively studied sites in the Neotropics.

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 |
Neotropical Secondary Forest Succession: Changes in Structural and Functional CharacteristicsBackgroundThis paper reiviews the main biotic and abiotic factors that influence patterns of secondary forest succession in the Neotropics after complete forest clearance due to human activities. Research Goals & MethodsThe authors look at patterns of species replacement and various processes that occur during succession and suggest that the sequence of processes may be predictable even if species composition is not.

Identifying Hotspots of Deforestation and Reforestation in Colombia (2001–2010): Implications for Protected AreasbackgroundThis article uses satellite imagery, MODIS MOD13Q1 Vegetation Indices 250 , the Virtual Interpretation of EarthWeb-Interface Tool (VIEW-IT) to conduct a land-use analysis of Colombia, mapping trends and "hotspot" areas of deforestation and of reforestation from 2001 to 2010. Research Goals & MethodsThe authors identify four hotspots of deforestation (clustered particularly in lowlands in the north of the country) and four of reforestation, mainly in the Andes highlands.

Reforestation of mangroves after severe impacts of herbicides during the the Viet Nam war: the case of Can GioBackgroundDue to years of armed conflict and the extensive use of toxic chemicals in Vietnam in the 1960s, tens of thousands of hectares of mangrove forests were destroyed. In 1978, the People's Committee of Ho Chi Minhi City recognized this lost and began investing in reforestation efforts. Open access copy available |
