Non-timber Forest Product Harvest does not Affect the Genetic Diversity of a Tropical Tree Despite Negative Effects on Population FitnessbackgroundThe authors investigated a relationship between exploitation of economically important mahogany in Benin and the species genetic diversity. The study is base on the theory that disturbances in forest habitats can lead to a decrease in diversity due to population fragmentation and increased inbreeding. Open access copy available |
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.

Participatory Forest Monitoring: An Assessment of the Accuracy of Simple Cost–Effective MethodsbackgroundThis article examines the feasibility of implementing participatory forest monitoring to conserve biodiversity and improving livelihoods for local communities. Long-term monitoring of forest conservation sites by professional scientists, is often cost prohibitive and uses techniques irrelevent to local community members, while simpler methods could be learned and implemented by local communities and more affordable.

Coffee Agroforests Remain Beneficial for Neotropical Bird Community Conservation across SeasonsBackgroundThis study compares bird community composition in coffee agroforestry systems with secondary forest fragments, while accounting for seasonal bird migration and differences in bird detectability between habitats. It was conducted in the San Luis Valley of northwest Costa Rica, a montane forest region that encompasses many microhabitats. Open access copy available |
Bird Perches Increase Forest Seeds on Puerto Rican LandslidesBackgroundForest regeneration is typically difficult after landslides due to loss of above- and below-ground vegetative structure, the soil seed bank, soil nutrients, and soil structure. Landslides are a common occurrence in Puerto Rico due to its steep topography and heavy rainfall periods and often transform into grass- or fern-dominated terrain. Insufficient seed rain is thought to be one contributing factor. Open access copy available |
Connecting sustainable agriculture and wildlife conservation: Does shade coffee provide habitat for mammals?BackgroundShade coffee systems are believed to support diverse wildlife. However, most research on wildlife in shade coffee has focused on bird and insect diversity, with few studies that have focused on mammals living within coffee-dominated landscapes.

Community Action for Biodiversity and Forest Conservation and Adaptation to Climate Change in the Wild Coffee Forests (CAFA)BackgroundLocated in southwest Ethiopia, the Kafa Biosphere Reserve is an important area for water quality, carbon storage, and a range of endangered and endemic species. Moreover, around 65,000 people live in the reserve, most of whom depend on subsistence agriculture for their livelihoods. Coffee also grows wild in the region, which locals often harvest for sale. Still, poverty and population growth is common within these communities, causing increasing strain on natural resources. To address these needs, Nabu began a community action project.

Biodiversity–Productivity Relationships in Small-Scale Mixed-Species Plantations Using Native Species in Leyte Province, PhilippinesbackgroundThe growth of tropical reforestation in recent decades has given rise to a debate between the relative productivity, biodiversity, and general merits of mixed-species vs. single-species plantations. To further investigate the relationship between tree species diversity, productivity, and abiotic factors such as climate and soil, this study investigated the growth of mixed-species plantations in Leyte province in the Philippines. These smallholder plantations were planted in 1992 to meet social, economic, and environmental needs through the Rainforestation Farming system. Open access copy available |
Carbon Footprint: Great Rift Valley, KenyaBACKGROUNDThis project takes place in the Kikuyu Escarpment, Western Kenya. The Kikuyu escarpment forest has a high biodiversity and the services the ecosystem provides, particular water, is a key source for neighboring communities' livelihoods. Environmental degradation through charcoal burning, logging for timber and fuel wood, ring-debarking for medicinal trees and overgrazing are negatively affecting these services and depleting the area of important vegetation cover.

Effects of Fragmentation of the Atlantic Forest on Mammal Communities in South-Eastern BrazilBackgroundThe author presents a detailed analysis of the community of large and medium-sized mammals present in six remnants of the low Atlantic forest in Brazil. The six remnants had varying sizes: small (200 ha), medium (2,000 ha) and large (20,000 ha). The study seeks to (1) identify the mammal species richness and the relative abundance of individuals surviving in each reserve, and (2) analyze changes in the structure of the mammal community contrasting the relative abundances of orders and dietary categories between reserves of differing sizes.
