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.

Restoration of seasonal semideciduous forests in Brazil: influence of age and restoration design on forest structure

Background

With the high rates of deforestation in tropical regions, the restoration of degraded lands has become an important way for maintaining the diversity of plant communities and for creating wildlife habitats. Evaluating the success of restored areas is essential for improving restoration designs and for successfully restoring such complex ecosystems.

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 and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa Rica

Background

As reforestation with native tree species gains in popularity, more information about proper management is needed. This study examines the growth and responses to thinning of ten native species in mixed and pure-species plantations in the Caribbean Lowlands of Costa Rica.

The Savannization of Moist Forests in the Sierra Nevada de Santa Marta, Colombia

Background

This study in the Sierra Nevada de Santa Marta seeks to determine if savannas are natural or caused by anthropogenic factors. The authors use climate data from the past and present, the location of vegetation, and land use history to test their hypothesis.

Seed rain and seed limitation in a planted gallery forest in Brazil

Background

Seed dispersal by wind (anemochorous) and animals, usually birds and bats (zoochorous), is an important driver of succession. This study examines seed rain in a planted gallery forest (riparian corridor) in Brazil.

Isolated Trees and Grass Removal Improve Performance of Transplanted Trema micrantha (L.) Blume (Ulmaceae) Saplings in Tropical Pastures

background

This research evaluates the survival and growth of saplings of Trema micrantha when transplanted into recently abandoned pastureland in southeast Mexico. Trema micrantha is a pioneer species native to Mexico with ecological and physiological properties that would make it viable for planting in open fields.

Banco de Sementes como Indicador de Restauração de uma Área Degradada por Mineração de Caulim em Brás Pires, MG

The authors germinated the seed bank from degraded former kaolin mining sites that have regenerated naturally for a period of 20 years. They used two light treatments usedfor the germination: one with 11.5% shade, and another with 60%. There was a wide range of variation among the species according to the light level, with some species producing far more seedlings under one treatment that the other. Most (2/3) of the species germinating (total n: 36) were herbaceous, with eight tree species (see above).
