Factors Limiting Tropical Rain Forest Regeneration in Abandoned Pasture: Seed Rain, Seed Germination, Microclimate, and SoilbackgroundThis research evaluates the ability of seeds to be dispersed into and germinate in areas of abandoned pasture. Research Goals & MethodsSeed rain, germination of tree seedlings, percent herbaceous and woody cover, soil moisture, phosphorous, air temperature, and other microclimate conditions were tested in plots located 250m and 25m from the forest edge as well as within the primary forest.

Dalbergia Sissoo Mortality in Bangladesh Plantations: Correlations with Environmental and Management ParametersbackgroundThis research seeks to correlate environmental and plantation conditions with the widespread mortality of Dalbergia sissoo trees planted in Bangladesh. Goals & MethodsIn order to understand the relationship between D. sissoo mortality and environmental and plantation characteristics, the authors examined 72 mixed plantations across five districts in Bangladesh.

Reforestation of Abandoned Pastures: Silvicultural Means to Accelerate Forest Recovery and BiodiversityBackgroundDespite the 2736 native tree species in Ecuador, the majority of forestation activities in the country are based on exotic pines and eucalypts. In this book chapter, the authors describe the reason for this neglect being the lack of knowledge on the ecology and silvicultural treatment and the lack of nurseries growing these species.

Initial Performance and Reforestation Potential of 24 Tropical Tree Species Planted Across a Precipitation Gradient in the Republic of PanamabackgroundThe authors of this study planted trees from 22 native species and two exotic species to use in selection trials testing the growth and survivability of trees in plantations in three different sites. Research Goals & MethodsThe sites were chosen for their precipitation gradient from Soberania National Park (2226mm mean annual rainfall), Los Santos (1946mm rainfall), and Rio Hato (1107mm rainfall). Survival, basal diameter, height, crown diameter and wood volume index (VI) were calculated after two years of growth. Available with subscription or purchase |

Institutional Dimensions of Payments for Ecosystem Services: An Analysis of Mexico's carbon Forestry ProgrammebackgroundIn recent years, Mexico has established a payment for environmental service (PES) program where governments pay rural communities and farmers for environmental service provisions: water quality, carbon fixation, biodiversity, etc. These PES programs have been more effective when designed by both providers and users collaboratively. In 2004, the Mexican government developed the program Payments for Carbon, Biodiversity and Agro-forestry Services (PSA-CABSA). Available with subscription or purchase |
Value and Risks of Expiring Carbon Credits from Afforestation and Reforestation Projects under the CDMbackgroundOne of the main concerns with afforestation and reforestation being part of the Clean Development Mechanism (CDM) is the issue of liability about the length and quality of the project (the risk of the forest or plantation being harvested or otherwise destroyed). To account for the non-permanent carbon storage of afforestation and reforestation projects, Credits for Emissions Reductions (CERs) can expire. Available with subscription or purchase |
Effects of Above- and Below-Ground Competition of Shrubs and Grass on Calophyllum brasiliense (Camb.) Seedling Growth in Abandoned Tropical PasturebackgroundThis article evaluates the above and below-ground competition between grasses, shrubs, and woody seedlings in abandoned pastures in montane Costa Rica. Research Goals & MethodsOne-year-old seedlings of Calophyllum brasilense, a native early-successional tree species, were planted in patches of shrub growth and grass coverage. Seedlings were treated in one of four ways: reduction of root competition, reduction of above-ground competition, reduction of both forms of competition, and control (untreated).
