Responses of 20 Native Tree Species to Reforestation Strategies for Abandoned Farmland in Panama

Background

In the tropics, deforestation often leads to unproductive agriculture and results in degraded grasslands. This study seeks to understand why forests fail to regenerate naturally in these ecosystems.

Tree Management in the Northwestern Andean Cordillera of Peru

Background

Peasant communities in the northwestern Andean Cordillera of Peru utilize many indigenous and introduced trees and shrubs to satisfy a variety of material needs. However, forest resources are over-harvested and over-grazed, contributing to soil erosion. This study aims to identify the major tree and shrub species in the region and understand their ecologies and usages, and to recommend priorities for reforestation in the region taking human usage into account.

The Lembo System: A Model for Agroforestry in Dipterocarp Forest Ecosystems of East Kalimantan

background

This article describes the Lembo system of agroforestry, a traditional practice by the Dayak people in East Kalimantan, Indonesia. In Lembo gardens, around 127 species of woody plants are cultivated, and up to 40 different species can be found per 0.25 ha 90% of which are trees. In those gardens, there is also a large diversity of wild, uncultivated plants.

Restoring rainforest fragments: Survival of mixed-native species seedlings under contrasting site conditions in the Western Ghats, India

Background

Historical fragmentation and a current annual deforestation rate of 1.2% in the Western Ghats biodiversity hotspot have resulted in a human-dominated landscape of plantations, agriculture, and developed areas, with embedded rainforest fragments that form biodiversity refuges and animal corridors. This study evaluates restoration efficacy for tropical rainforest under three different site conditions in the Anamalai hills, India.

Screening trial of 14 tropical hardwoods with an emphasis on species native to Costa Rica: Fourth year results

Background

Commercial forestry plantations have consistently relied on a limitd number of species, often favoring exotic species over native ones. This is mainly due to a lack of information or understanding related to the silviculture of native species plantations. This article uses a long-term experiement site in Costa Rica's La Selva Biological Station to work towards filling this knowledge gap.

Growth of native forest species planted on abandoned pasture land in Costa Rica

Background

Reforestation programs in Costa Rica have largely utilized only four tree species. This study tests growth rates and form of eleven additional tree species native to the humid tropics, including five N-fixing species and six non-N-fixing species.
