Shade coffee farms promote genetic diversity of native trees

Background

In 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.

NParks Flora and Fauna Web, Singapore

About

NParks Flora&FaunaWeb was developed to provide information on both flora and fauna of Singapore.

Content

The database contains 4719 profiles for plants and 819 for fauna, each of which lists the species' latin names, the common names, pictures of the species, and spaces in which people can add information on biogeography, plant care and propagation, and other characteristics. The website also offers downloadable resources for field guides, comparison charts, spot comparisons, and a monthly newsletter.

Public Awareness Generation for the Reforestation in Amazon Tropical Lowland Region

background

This 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 & Methods

After 9 years, tree height, DBH, species composition, stand volume, tree density and species diversity were measured in both plots.

Optimising Seedling Management: Pouteria sapota, Diospyros digyna, and Cedrela odorata in a Mexican Rainforest

background

This 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 & Methods

The effects of canopy closure, leaf nutrients, initial seedling height and seed mass on the final height of the plant after two years were analyzed.

Restoration of a Sri-Lankan rainforest: Using Caribbean Pine Pinus caribaea as a nurse for establishing late-successional tree species

Background

In the moist tropics, studies have demonstrated poor seedling establishment of late-successional trees on lands cleared of forest. This study examines the potential for establishing late-successional tree species that dominate the canopy of rainforest by planting within and adjacent to experimental openings that were created within a Pinus caribaea plantation.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa Rica

Background

Reforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land.

Tropical Dry Forest Recovery: Processes and Causes of Change

BACKGROUND

This 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.

Evaluation of Trees Indigenous to the Montane Forest of the Blue Mountains, Jamaica for Reforestation and Agroforestry

background

This study investigates local knowledge of native species and their uses in agroforestry systems, as well as the establishment of native species in the Blue Mountains of Jamaica.

Research Goals & Methods

Interviews were conducted with 27 local participants to determine the use of 80 taxa of trees and shrubs, 43 of them native taxa; the value of each species was calculated for 10 uses.
