Natural Regeneration
Colonization of Non-Planted Mangrove Species into Restored Mangrove Stands in Gazi Bay, KenyaBackgroundAs mangroves are being recognized as some of the world’s most productive ecosystems, restoration efforts are being undertaken around the world. Not all projects are successful, however. This study will potentially help mangrove restoration practitioners with species selection. Available with subscription or purchase |
Influence of species richness and environmental context on early survival of replanted mangroves at Gazi bay, KenyaBackgroundMangrove restoration is often unsuccessful, thus this study involves long-term large-scale experiments measuring a range of ecosystem functions in replanted mangrove stands in Ghazi in Kenya funded by Earthwatch.

Consequences of plantation harvest during tropical forest restoration in UgandaBackgroundTimber plantations have recently received considerable attention as a forest restoration strategy for heavily degraded lands in the humid tropics. Plantations can facilitate secondary forest regrowth by providing an understory environment more favorable for native plant recruitment than unmanaged degraded habitats. This study explores how using plantations as a restoration tool affects forest succession; how initial floristics affect successional pathways; and the effect of fire exclusion or other interventions.

Seed Dispersal Distances and Plant Migration Potential in Tropical East AsiaBackgroundMost 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. Available with subscription or purchase |
Helping Forests to Help Themselves—Accelerating Natural RegenerationbackgroundThis chapter walks through the basic techniques of accelerated (or assisted) natural regeneration (ANR), describing when it is appropriate, when it should be combined with other techniques, how to increase the seed rain, and areas of needed research.

Fire in the Seasonal Semideciduous Forest: Impact and Regeneration at Forest EdgesbackgroundThis study looks at a fragment of semi-deciduous forest in Brazil to determine the effects of fire on vegetation at varying distances from the fragment’s edge, as well as the recovery of forest structure and species diversity after fire.

Releasing Rain Forest Succession: A Case Study in the Dicranopteris linearis Fernlands of Sri LankabackgroundThis study evaluates the effectiveness of different site treatments for controlling the invasive fern Dicranopteris linearis which has arrested forest succession in areas of the Sinharaja Man and Biosphere (MAB) reserve in lowland Sri Lanka. The fernlands, which had existed in the reserve for 10-20 years before this study, are favored by forest clearance for swidden agriculture and periodic fires.

The Potentials of 20 Indigenous Tree Species for Soil Rehabilitation in the Atlantic Forest Region of Bahia, BrazilbackgroundThis research presents the effects of 20 native tree species planted in 1974-1975 on different soil conditions in Bahia, Brazil. Research Goals & MethodsIn pure stands of the native species (some nitrogen-fixing) as well as a nearby 25 year old secondary forest, primary forest, and mixed-species plantation, soils were evaluated for the following conditions: depth, % carbon, % nitrogen, phosphorous, potassium, calcium, magnesium, dry weight of forest floor litter, pH, and nodules.
