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.

Effects of Fragmentation of the Atlantic Forest on Mammal Communities in South-Eastern Brazil

Background

The 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.

Modification of Tropical Forest Patches for Wildlife Protection and Community Conservation in Belize

background

This chapter highlights the forest management practices that are practiced in a fragmented tropical forest in Belize.  The project began in 1985 and includes 8 villages home to approximately 450 people. The forested area is fragmented but howler monkeys are not hunted and have coexisted at the site with humans for many years. The project area includes 45 km² , but approximately half is cleared, and remaining forest is centered in the riparian areas.

Patch Size Effects on Avian Foraging Behaviour: Implications for Tropical Forest Restoration Design

background

This study looks at bird behavior in restoration sites in southern Costa Rica. While multiple studies examine the presence of birds in restored forest, few studies examine behavior in these sites.

The Value of Rehabilitating Logged Rainforest for Birds

Background

This study examines a lowland, dry dipterocarp forest in Sabah, Malaysia that had been selectively logged in 1988-89. One area was rehabilitated (enrichment planting and liberation cutting of vines, bamboos, and noncommercial species). This area was surrounded by a naturally reforesting area. The authors suggest that rehabilitation of selectively logged forests is a more effective carbon sink than plantations.

Seed Dispersal and Potential Forest Succession in Abandoned Agriculture in Tropical Africa

Background

Forest succession on disturbed and post-agrarian lands is often slow because the resources necessary for succession – such as soil nutrients, seeds, and moisture – are depleted. In such areas, succession may depend on bat- and bird-dispersed seeds arriving from distant forest patches.

Seed Dispersal Distances and Plant Migration Potential in Tropical East Asia

Background

Most predictions of vegetation responses to anthropogenic climate change over the next century are based on plant physiological tolerances and do not account for the ability of plant species to migrate over the distances required in the time available, or the impact of habitat fragmentation on this ability. This review assesses the maximum routine dispersal distances achievable in tropical East Asia and their vulnerability to human impacts.
