Survival and Growth of Under-Planted Trees: A Meta-Analysis Across four Biomes

background

This article is a meta-analysis synthesizing the results of survival and growth of under-planted trees in forests in tropical, temperate coastal, boreal, and temperate deciduous forests. Additionally, the survival and growth of these underplanted trees are evaluated according to the silvicultural treatment affecting density of the overstory: uncut, dense shelterwood, intermediate density shelterwood, light density shelterwood, clear cut.

Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

Maya Nut Reforestation

Background

Maya Nut is an NGO that seeks to find balance between people, forests, and food. While they do not run a reforestation program directly, they do work closely with communities to reforest degraded lands throughout Latin America. The mission of the program is to conserve the Maya nut tree, Brosimum alicastrum, by planting trees and teaching rural and indigenous women to harvest and process the seed for food and income.

Tree biodiversity in farmer cooperatives of a shade coffee landscape in western El Salvador

background

Conservation of tropical biodiversity in agricultural landscapes has become more important as the area covered by natural ecosystems decreases. Understanding the types of biodiversity common in agriculturally managed lands, and involving farmers in conservation planning, is important for regional conservation goals.

Tree regeneration in church forests of Ethiopia: effects of microsites and management

Background

Tree regeneration is severely hampered in the fragmented afromontane forests of northern Ethiopia. Pressures of harvesting and grazing and climactic conditions present challenges to regeneration. This study explores how trees regenerate in remnant forests along the gradient from open field, forest edge to closed sites and canopy gaps inside the forest.

Ecological Study of Kirisia Forest Reserve

Background

In order to inform a 2009 Conservation Enterprise Development Program, a preliminary ecological survey was carried out at the Kirisia Forest Reserve in Samburu District, Kenya. The survey was in response to an aerial survey conducted by the Wilderness Foundation UK that examined potential drivers of forest destruction.
