Shade effect on coffee production at the northern Tzeltal zone of the state of Chiapas, MexicoBackgroundShade-grown coffee has been a preferred method in the tropics largely due to its benefits for biodiversity. However, impacts on yield are not yet fully understood, nor are the potentials for multiple uses of canopy species. Open access copy available |
Shade coffee farms promote genetic diversity of native treesBackgroundIn the tropical Americas, coffee is typically cultivated under shade canopy cover. Unlike coffee grown in full sun, shade-grown coffee plays host to an increased diversity of vertebrates and invertebrates. However, the contributions of shade-grown coffee patches in tropical landscapes towards preserving genetic flows have not yet been studied. Open access copy available |
The Role of Rustic Coffee Plantations in the Conservation of Wild Tree Diversity in the Chinantec Region of MexicobackgroundThis study examines the potential of shade coffee systems to promote native tree diversity across the landscape of southern Mexico. Research Goals & MethodsTwenty-two coffee plantations, representing a range of elevation and age of development, were sampled to assess their species compositions. In total, 45 species (34 tree species) were recorded in the plantations, and 77% of them were native species. Open access copy available |
A Comparative Study of Tree Establishment in Abandoned Pasture and Mature Forest of Eastern AmazoniaBackgroundThis study compares seedling establishment, seed availability, seed predation, seedling herbivory, and abiotic barriers to tree establishment in recently abandoned pasture, treefall gaps, and mature forest understory in Pará State, Brazil.

Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

Tropical Dry Forest Recovery: Processes and Causes of ChangeBACKGROUNDThis paper aims at unraveling processes and pathways of tropical dry forest (TDF) secondary succession occurring after traditional shifting-cultivation practices. It focuses on the study of community dynamics, the development of forest structure, and changes in floristic composition, to understand what makes a group of species to be present, dominant, and eventually disappear, at a certain space and time. The work begins with a section on the use of tree rings to determine the ages of fallows. Open access copy available |
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.

Performance of forest plantations in small and medium-sized farms in the Atlantic lowlands of Costa RicaBackgroundWhile exotic trees are typically used in plantations throughout the tropics, there has been recognition that certain native species are also suitable. This study aims to compare the viability of both native and exotic tree species for plantation use. Open access copy available |
