Secondary & Degraded Forest Restoration
Rehabilitation of Degraded Forest with Shorea leprosula and S. selanica CuttingsbackgroundThis article describes limits to dipterocarp-based reforestation due to irregular flowering pattern, short seed storage period, and uncertain planting techniques in Southeast Asia. In West Java, Indonesia, the authors test the effectiveness of vegetative propagation for two species of fast-growing dipterocarps: Shorea leprosula and Shorea selanica. Open access copy available |
Effects of Nutrient Addition, Mulching and Planting-Hole Size on Early Performance of Dryobalanops aromatica and Shorea parvifolia Planted in Secondary Forest in Sarawak, MalaysiabackgroundIn this study, three methods were tested for their ability to improve growth of dipterocarp seedlings planted in west Sarawak, Malaysia.

Release from Root Competition Promotes Tree Seedling Survival and Growth Following Transplantation into Human-Induced Grasslands in Sri LankabackgroundThis study evaluates the growth and survival of four native tree species planted as seedlings in grasslands situated in previously abandoned tea plantations. Research Goals & MethodsEach seedling underwent one of eight different treatments based the various combinations of: with or without root competition, shoot competition, and vertebrate herbivory. Seedlings that died within the first month were replaced. Growth and survival was evaluated at 18 and 28 months. Available with subscription or purchase |

Restoration of seasonal semideciduous forests in Brazil: influence of age and restoration design on forest structureBackgroundWith the high rates of deforestation in tropical regions, the restoration of degraded lands has become an important way for maintaining the diversity of plant communities and for creating wildlife habitats. Evaluating the success of restored areas is essential for improving restoration designs and for successfully restoring such complex ecosystems. Open access copy available |
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.

Enrichment Planting of Dipterocarps in Logged-Over Secondary Forests: Effect of Width, Direction and Maintenance Method of Planting Line on Selected Shorea SpeciesbackgroundIn this study, three different planting design experiements were conducted using three Dipterocarp tree species planted in a heavily logged area of South Kalimantan. The area was logged in 1979 and used for shifting cultivation until 1988. Available with subscription or purchase |
Experimental Tree Assemblages on the Ecological Rehabilitation of a Cloud Forest in Veracruz, MexicobackgroundThis research evaluates the survival of 10 native tree species planted in a heavily degraded montane forest in Veracruz, Mexico. Available with subscription or purchase |
Central Kalimantan Peatlands Restoration ProjectBackgroundIn Central Kalimantan, Indonesia, the peatswamps have been increasingly destryoyed by drainage, illegal logging and fire, which has impactd local livelihoods, the economy, and wildlife habits, along with contributed to greenhouse gas emissions. The Central Kalimantan Peatlands Project (CKPP) was started to respond to this problem. Open access copy available |
