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.

The Role of Seed Banks in Vegetation Dynamics and Restoration of Dry Tropical Ecosystems

Background

This paper reviews studies on seed banks in tropical dry forests, comparing them with wet tropical and subtropical vegetation.

Research Goals & Methods

Seed banks in dry tropical forests tend to be low and they are density dependant on moisture levels of the area in question. Subtropical seed banks had similar values to dry tropical forests. Majority of the seeds are from pioneer forests.

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.

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 Dry Tropical Forest Fragmentation on the Reproductive Success and Genetic Structure of the tree Samanea saman

background

Tropical trees are particularly vulnerable to forest fragmentation due to low population densities and reproductive self-incompatibility. Forest fragmentation is likely to decrease gene flow, increase endogamy, and eventually produce a high differentiation among remnant populations.

Self-restoration of post-agrogenic soils of Calcisol-Solonetz complex: Soil development, carbon stock dynamics of carbon pools

Background

Abandoned land may move towards self-restoration without human intervention. In the European part of Russia, over half a million km2 was abandoned between 1987 and 2007; another 200,000 km2 was abandoned in Eastern Russia. The majority of abandonments occurred in unirrigated dry steppe, land that is arable but less favorable for agriculture. This study compares differences in self-restoration based on underlying soil types, climate, and land-use history across a chronosequence of abandoned land in the dry steppe zone of Russia in a Calcisol–Solonetz complex, reporting on vegetation and soil characteristics.

Vegetation Structure, Species Diversity, and Ecosystem Processes as Measures of Restoration Success

Background

This article provides an example of how to evaluate forest restoration using integrative methods, including measures of vegetation structure, species diversity, and ecosystem processes. Specifically discussed are four measures of vegetation structure, four measures of species diversity, and six measures of ecosystem processes.

Assessing and Monitoring Forest Biodiversity: A Suggested Framework and Indicators

background

This study looks at afforestation and reforestation (A/R) projects that are part of the Kyoto Protocol's Clean Development Mechanism. The study seeks to determine whether large-scale A/R projects meet the twin goals of carbon sequestration and sustainable development, using projects in India's Karnataka State as case studies.
