Ecosystem Services and Ecological Processes
Promoting Biodiversity Co-Benefits in REDDbackgroundThis article describes the potential for maximizing biodiversity conservation as a co-benefit of REDD (Reduced Emissions from Deforestation and Degradation). Open access copy available |
The Agua Salud Project, Central PanamaBackgroundThe Agua Salud Project is located in the watershed that includes and surrounds the Panama Canal, an engineering feat that largely relies on natural hydrological systems. Much of this watershed has been deforested, thus an official policy has been put into place to reforest and regain ecosystem services. This project seeks to utilize the globalize role of the canal to bring attention to the ecosystem services of the region. Open access copy available |
Large-scale Ecological Restoration of Degraded Tropical Forest Lands: The Potential Role of Timber PlantationsbackgroundThis study offers suggestions for how timber plantations can be designed to yield timber and improve biodiversity on cleared and degraded lands.

Application of Mycorrhizal Roots Improves Growth of Tropical Tree Seedlings in the Nursery: A Step Towards Reforestation with Native Species in the Andes of EcuadorbackgroundEcuador’s tropical mountain rainforests are rich in biodiversity but are facing the highest deforestation rate in South America (1.7%). Tree plantations are one method being used to restore these forests, however these plantations often use fast-growing introduced species rather than native species. To improve the success of native species in order to encourage their greater use in plantations, this study proposes inoculation of nursery seedlings with the arbuscular mycorrhizal (AM) fungi that is associated with these native species in the forest.

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.

Conceptual Framework for Mangrove Restoration in the Yucatán PeninsulaBackgroundIn the Yucatán Peninsula, mangroves were lost at a rate of around 1.84% per year between 1976 and 2000. In 2000, the North American Wetlands Conservation Council gave the state government of Yucatán $800,000 towards mangrove restoration projects. Some research shows that the projects funded by this grant did not fully meet restoration goals. Open access copy available |
Site and species selection — Changing perspectivesBackgroundPlantation forestry in the tropics today is characterized by increasing refinement of matching species with site and increasing emphasis on non-industrial purposes for growing trees. This perspective comments on the increased number of objectives that a tropical forester or scientist is called upon to fulfill. Available with subscription or purchase |
Rationale and Methods for Conserving Biodiversity in Plantation ForestsbackgroundWhen compared to degraded lands, developed lands, or areas of intensive industrial agriculture, forest plantations can positively contribute to biodiversity conservation. However, when monoculture stands of exotic trees, or native trees not typically found in single-species stands are used for plantations, they have been found to have impoverished flora and fauna compared with natural forest.

Understory Development in Young Cordia alliodora PlantationsbackgroundThis article presents the findings of a study evaluating the biomass and composition of understory plants in 1- and 5- year old plantations at the La Selva Biological Station in Costa Rica. Reserach Goals & MethodsThis study sampled plantations of Cordia alliodora in monoculture plots and in polyculture plots with trees interplanted with monocots (Euterpe macrospadix, Euterpe oleracea, and Heliconia imbricata).

Tropical Forest Restoration: Tree Islands As Recruitment Foci In Degraded Lands Of HondurasBackgroundMethods to accelerate forest recovery must address a number of impediments including limits on seed dispersal and microclimactic extremes. This study evaluates the ability of tree islands to serve as recruitment foci for additional seeds in a two-year study in northern Honduras. Available with subscription or purchase |
