Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.

Régénération naturelle assistée: Gestion des arbres champêtres au Sahel (Assisted natural regeneration: management of wild trees in the Sahel)

The authors outline threats to forest regeneration in the Sahel, particularly with regard to agroforestry systems. Better agroforestry practices that incorporate assisted natural regeneration would allow for more sustainable availability of firewood and productivity of agroforestry systems. The authors strongly advocate for major changes in behavior and politics, including decentralization of authority over forest resources.

Bioremediation of a crude-oil polluted agricultural-soil at Port Harcourt, Nigeria

Background

Since more than 98% of Nigeria’s current economic support is crude oil, and oil spills are in inevitable and frequent, six treatment sample-cell were tested on the soils of the Niger Delta of Nigeria for crude oil bioremediation. Oil spills cause nitrogen levels to decrease, while increasing carbon content. A decrease in nitrogen and the toxicity of crude oil reduces the growth of heterotrophic bacteria, which utilize petroleum carbon for cell synthesis.

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.

Evaluation of Andean Alder as a Catalyst for the Recovery of Tropical Cloud Forests in Colombia

background

This study compares the species composition and structural diversity of 30-year-old alder plantations with adjacent, naturally regenerated forests of the same age. The study seeks to determine if alder plantations are an appropriate catalyst for forest regeneration for conserving biological diversity and to determine if the differences between the two forest types are maintained over time.

Reasons for reforestation success and failure with three mangrove species in Colombia

Background

This study examines the mortality and growth rates of the propagules, seedlings and saplings of three native mangrove species (A. germinans, L. racemosa, and R. mangle) in order to determine the ecological factors that influence tree growth and survival in deforested mangroves with restored hydrologic conditions on the Caribbean coast of Colombia.

Native Trees and Shrubs for the Productive Rehabilitation of Tropical Cattleranching Lands

background

The authors of this study examined strategies to improve cattle ranching in Colombia and Mexico through the use of intensive silvopastoral systems. Silvopastoral systems transform extensive cattle ranching with intensively managed systems with high densities of trees and shrubs to improve yields and environmental impacts.

Cattle and Weedy Shrubs as Restoration Tools of Tropical Montane Rainforest

background

In abandoned Latin American pastures, grasses often inhibit the establishment of woody species. This study tests the effect of cattle grazing on woody and herbaceous vegetation establishment in pastures of P. clandestinum and M. minutiflora.
