Biodiversity–Productivity Relationships in Small-Scale Mixed-Species Plantations Using Native Species in Leyte Province, Philippines

background

The 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.

Early Effects of Four Fast-Growing Tree Species and Their Planting Density on Ground Vegetation in Imperata grasslands

background

This study aims to test the success of fast-growing exotics tree species and alternative planting densities on the development of ground vegetation. The study was conducted in Riam Kiwa, South Kalimantan, Indonesia in Imperata grasslands. The four fast-growing exotic tree species used in the study were Acacia mangium, Acacia crassicarpa, Gmelina arborea, and Paraserianthes falcataria.

Priority Setting for Scaling-Up Tropical Forest Restoration Projects: Early Lessons from the Atlantic Forest Restoration Pact

Background

The Atlantic Forest Restoration Pact (AFRP) serves as a network of different stakeholders at all scales, from local farmers and landowners with a few hectares on local scales to environmental action groups and policy makers on an ecosystem scale. There are currently over 200 stakeholder partners involved in the network, though it is not an NGO yet as of the publication of this article. The AFRP seeks to restore 15M ha of deforested land by 2050, the majority of which is land that, compliant with the Brazilian Forest Code, should be forest land.

Overcoming Ecological Barriers to Tropical Lower Montane Forest Succession on Anthropogenic Grasslands: Synthesis and Future Prospects

Background

This review attempts to address the difficulty in restoring grasslands to secondary tropical forest through reforestation. Proposed strategies are discussed for future recruitment methods for woody vegetation.

Research Goals & Methods

This study examines work conducted in Knuckles Forest Reserve (KFR) in the lower montane tropical rainforest and grasslands of Sri Lanka.

Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, Brazil

Background

Gold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil.

Seeding ecological restoration of tropical forests: Priority setting under REDD+

Background

Tropical deforestation continues to be the major driver of biodiversity loss and a considerable contributor to climate change. Increasing numbers of forest-dependent rural poor rely on degraded forest for their livelihoods. Ecological restoration of tropical forests has the potential to not only contribute to biodiversity conservation and climate mitigation, but also poverty alleviation. REDD+ provides a potentially powerful mechanism for supporting ecological restoration of tropical forests in developing countries.

Drought, Fire, and Tree Survival in a Borneo Rainforest, East Kalimantan, Indonesia

Background

While draughts and fires are seen as important components of tropical forests, large-scale assessments of the effects of these events are scarce. This paper compares the forest stand level impact between severe drought and a subsequent extensive fires on forest stand in a lowland rainforest in East Kalimantan.

Degraded Lands Worth Protecting: the Biological Importance of Southeast Asia's Repeatedly Logged Forests.

Background

The study examines the impacts of second logging cycles on biodiversity by comparing species richness, species composition and population-level responses of birds and dung beetle species across unlogged forest, first rotation forest, and second rotation forest in Sabah, Malaysia.

Research Goals & Methods

The authors sample 18 sites, 6 for each forest type, over a two year period. They use point count and mist net censuses for bird species and pitfall traps to count dung beetles.

Interactions among Amazon Land Use, Forests and Climate: Prospects for a Near-Term Forest Tipping Point

Background

This study concerns the interaction of anthropogenic and natural threats on the Amazon forest and considers the possibility of a tipping point in the near future. The authors argue that the interaction of various factors may lead to a large-scale forest dieback, for example a deforestation of about 31% of the Amazon closed-canopy forest formation.
