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.

Shade management in coffee and cacao plantations

Background

Shade trees reduce the stress of coffee (Coffea spp.) and cacao (Theobroma cacao) by ameliorating adverse climatic conditions and nutritional imbalances and increase the biodiversity of coffee farms, but they may also compete for growth resources. This review summarizes the literature on ecological aspects of shade-grown coffee and cacao and on management of shade trees, but does not address economic and social aspects of shade-grown coffee and cacao.

Contextual Analysis of Agroforestry Adoption in the Buffer Zone of Podocarpus National Park, Ecuador

Background

Promoting sustainable agriculture and community development has been an important strategy both to alleviate resource pressures on Ecuador’s Podocarpus National Park (PNP) and surrounding forested areas in its buffer zone, and to aid local communities. However, many contextual factors drive neighboring rural and agricultural communities to put pressure on PNP and the surrounding landscape.

Applied Nucleation as a Forest Restoration Strategy

background

To combat deforestation and restore forest cover quickly and efficiently, this article proposes the use of applied nucleation as a restoration strategy. The article reviews research to date on applied nucleation, which is a method for restoring degraded landscapes in which small clusters of shrubs and trees are planted to encourage natural forest regeneration.

Growth of dipterocarp seedlings in artificial gaps: An experiment in a logged-over rainforest in South Kalimantan, Indonesia

Background

Regeneration of dipterocarps following logging has become a crucial issue in tropical forest management. Secondary forest frequently and rapidly replaces dipterocarps in large logged-over patches. If unmanaged, these secondary forest patches are often composed of unmerchantable early-succession species. It has been hypothesized that dipterocarps grow most successfully in small gaps.
