Environmental Services of Native Tree Plantations and Agroforestry Systems in Central America

Background

Plantations and agroforestry systems supply wood and environmental services such as carbon sequestration and recovery of biodiversity. At the time of writing (2004), Central American countries were developing systems of payments for environmental services to encourage the development of these systems.

Growth of Euterpe edulis under forest and agroforestry in southern Brazil

Background

The shade-tolerant palm Euterpe edulis is prevalent in native forests and in reforestation of banana plantations in Brazil. However, there are no data comparing its plantation growth performance to its native forest growth. This study evaluates growth and mortality of E. edulis planted in secondary dense forest and in banana plantations, as well as their relationships with site variables.

Rehabilitation of Tropical Rainforests Based on Indigenous Species for Degraded Areas in Sarawak, Malaysia

background

This study describes the success of native species planted in areas of abandoned shifting cultivation in Sarawak, Malaysia.

Research Goals & Methods

Site contitions in which species were planted included:  open conditions, including severely eroded and compacted areas and man-made mounds, and shady conditions. Growth and survival was recorded for 60-72 months, depending on the site

Payments for Environmental Services in Latin America as a Tool for Restoration and Rural Development

Background

Two Payments for Environmental Services (PES) projects are assessed in this article: 1) a bundled PES system in forestry projects in Costa Rica, and 2) the Regional Integrated Silvopastoral Approaches to Ecosystem Management Project in Costa Rica, Nicaragua and Colombia. The first project based PED on the provision of four different environmental services (carbon sequestration, biodiversity conservation, watershed protection, and aesthetic improvements and/or maintenance of the landscape) within the same plot of land. The second project implemented PES proportional to carbon sequestration and biodiversity outputs by participants.

Rehabilitation of Degraded Forest with Shorea leprosula and S. selanica Cuttings

background

This article describes limits to dipterocarp-based reforestation due to irregular flowering pattern, short seed storage period, and uncertain planting techniques in Southeast Asia. In West Java, Indonesia, the authors test the effectiveness of vegetative propagation for two species of fast-growing dipterocarps: Shorea leprosula and Shorea selanica.
