Restoration and Management Strategies
Public Awareness Generation for the Reforestation in Amazon Tropical Lowland RegionbackgroundThis study compares two plots of native tree species, one that was planted with small numbers of species representing potential natural vegetation and another that was planted with many species, including fast-growing pioneers. Research Goals & MethodsAfter 9 years, tree height, DBH, species composition, stand volume, tree density and species diversity were measured in both plots. Open access copy available |
Optimising Seedling Management: Pouteria sapota, Diospyros digyna, and Cedrela odorata in a Mexican RainforestbackgroundThis study compares the height growth of three native tree species (Pouteria sapota, Diospyros digyna, and Cedrela odorata) during the first two years after transplantation from a nursery in three plot types (primary rainforest, secondary forest, and open pasture) in Veracruz, Mexico. Research Goals & MethodsThe effects of canopy closure, leaf nutrients, initial seedling height and seed mass on the final height of the plant after two years were analyzed.

Experiments on Ecological Restoration of Coal Mine Spoil using Native Trees in a Dry Tropical Environment, India: A SynthesisbackgroundThis article outlines a series of experiments on the growth performance of 17 native tree species, as well the suitability of select species for use in plantations and to restore soil fertility on an abandoned coal mine in India. All 17 species grew in degraded mine soil, with A. catechu, B. racemosa, D. strictus, L. coromandelica and T. arjuna showing the highest biomass accumulation in mine soil; certain species showed higher biomass accumulation in mine soil fertilized with full or half doses of NPK.

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 |
Agroforestry for Ecosystem Services and Environmental Benefits: An OverviewbackgroundThis article reviews research on the ecosystem services and environmental benefits of agroforestry, focusing on the following: 1) carbon sequestration, 2) biodiversity conservation, 3) soil enrichment, and 4) air and water quality. Open access copy available |
Carbon sequestration in tropical agroforestry systemsBackgroundAgricultural lands are considered to be a major potential carbon sink, especially if trees are re-integrated with crops and/or animal agriculture. However, agroforestry systems are very diverse and are frequently used in small-scale settings, presenting challenges to carbon sequestration estimates. Available with subscription or purchase |
Applying Indigenous Knowledge to the Restoration of Degraded Tropical Rain Forest Clearings Dominated by Bracken FernbackgroundThe indigenous Lacandon Maya people of southern Mexico use a rotational agriculture system known in Spanish as the milpa for production of maize and other crops. This system rotates production to different plots, allowing the forest and soil to recover in the fallow years between production periods. In some cases, the Lacandon people actively manage forest recovery, sowing Balsa trees to prevent plots from being taken over by the invasive Bracken fern. Available with subscription or purchase |
Creative Ecology: Restoration of Native Forests by Native TreesbackgroundThis article describes how the "native forests by native trees" restoration method used in Japan was applied to reforestation in Malaysia, and later in Brazil, Chile, and parts of China. Open access copy available |
Assisted Natural Regeneration: Methods, Results and Issues Relevant to Sustained Participation by CommunitiesBackgroundThis article describes forest restoration in Kandis village on Palawan Island, Philippines, an assisted natural regeneration (ANR) project, and focuses on the social issues that affect success of ANR projects. research goals & methodsThe ANR approached used includes fire prevention, ring-weeding, and flattening of grasses.

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.
