Infuence of tree cover on diversity, carbon sequestration and productivity of cocoa systems in the Ecuadorian AmazonBackgroundIn this study, Jadan et al. objective was to evaluate the relationship between richness and floristic diversity, carbon storage, ecosystem services, agricultural productivity, and forest use potential under three land use systems in the Ecuadorian Amazon: cocoa-based agroforestry, cocoa monoculture and primary forest. In this region, one of the most important cultivation systems is the “Chakra”, a traditional organic farming production system, mainly practiced by indigenous peoples, that consists in the cultivation of staple crops in combination with commercial valuable species such as cocoa, obtaining multiple benefits.

Patterns of local wood use and cutting of Philippine mangrove forestsBackgroundHarvesting for wood in mangroves is a common practice yet there has been limited studies. This paper takes a unique approach through integrating ecological and ethnographic methods in order to study local wood use and cutting of mangrove forests in two areas of the Philippines. Goals & MethodsThe author conducted a series of 202 household interviews to determine how villagers used mangrove resources in North and South Bais Bay and Bindoy, Negros Oriental, and on Banacon Island, Bohol.

Tree species selection for a mine tailigns bioremediation project in PeruBackgroundThis article explains a project in southern Peru where tree plantings were used as bioremediation for treating tailings water from a copper mine. A variety of 25 tree species were selected for trial plantings on the site that could also be suitable for fuel and construction wood in the future. Available with subscription or purchase |
Dominant species' resprout biomass dynamics after cutting in the Sudanian savanna-woodlands of West Africa: long term effects of annual early fire and grazingBackgroundGiven widespread anthropogenic disturbance and land degradation across the Sudanian savanna-woodlands of West Africa, these researchers examined the impacts of early annual fire and grazing on 6 dominant plant species in terms of: shoot mortality, height and girth. Though rather unoriginally, they hypothesized that forest biomass reconstitution is affected by disturbances such as fire and grazing. Open access copy available |
Using artificial canopy gaps to restore Puerto Rican Parrot (Amazona vittata) habitat in tropical timber plantationsBackgroundThis study tests whether or not man-made canopy gaps can restore native tree diversity as food sources for the endagered Puerto Rican Parrot (Amazona vittata). The site is located within a non-native blue mahoe (Hibiscus elatus) plantation in the Río Abajo forest in central Puerto Rico, where the researchers planted native species in assisted natural regeneration. The gaps were created in 20m x 20m plots by girdling and applying herbicide on non-native trees and by clearing leaf litter and vegetation, creating space for planted and naturally established advance regeneration seedlings.

Early effects of four fast-growing tree species and their planting density on ground vegetation in Imperata grasslandsBackgroundThe study aimed to test the early effects of four successful reforestation fast-growing exotics tree species and alternative planting densities on the development of ground vegetation. The study was conducted in Riam Kiwa, South Kalimantan, Indonesia in Imperate grasslands. The four fast-growing exotics tree species used in the study were Acacia mangium, Acacia crassicarpa, Gmelina arborea, and Paraserianthes falcataria. Available with subscription or purchase |
Initial performance and reforestation potential of 24 tropical tree species planted across a precipitation gradient in the Republic of PanamaBackgroundPanama has experience significant forest loss due to the conversion of forest lands to agriculture and pasture, causing significant negative effects on ecosystems. Since natural regeneration is slow, the country has recently turned to plantation forestry in order to restore these degraded. Yet, many of these initiatives simply use a few exotic species. This study explores the performance of a range of species, including both native and exotic, in order to better ensure the success and adoption of diversified reforestation strategies.
