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.

A Comparative Study of Tree Establishment in Abandoned Pasture and Mature Forest of Eastern Amazonia

Background

This study compares seedling establishment, seed availability, seed predation, seedling herbivory, and abiotic barriers to tree establishment in recently abandoned pasture, treefall gaps, and mature forest understory in Pará State, Brazil.

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa Rica

Background

Reforestation of degraded land in tropical regions provides one means of restoring ecosystems and improving rural livelihoods. Most plantations in humid tropical regions are established in pure plots using few species of high commercial value, generally exotics. This study compares growth and economic viability of native trees in pure and mixed plantations on degraded land.

Plantaciones forestales con especies nativas: Una alternativa para la producción de madera y la provisión de servicios ambientales (Native species tree plantations: and alternative for wood production and environmental services)

Se presenta un panorama general del desarrollo de las actividades de plantaciones forestales en Costa Rica, así como algunos resultados de ensayos de rehabilitación de áreas degradadas con especies forestales nativas en la Estación Biológica La Selva. Durante 12 años, se midió anualmente el crecimiento y la producción de biomasa aérea de doce especies nativas en rodales mixtos y puros, como asi también la fertilidad del suelo bajo plantaciones puras de cuatro especies forestales nativas.

Growth in pure and mixed plantations of tree species used in reforesting rural areas of the humid region of Costa Rica, Central America

Background

Despite government incentives in Costa Rica for establishing and maintaining native tree plantations since the 1990s, farmers and small landowners often lack adequate knowledge about plantation management. Yield and rotation periods for each of the ten most common species grown in monoculture have previously been published. This paper compares productivity in monoculture and mixtures at La Selva Biological Station in the Caribbean lowlands of Costa Rica.

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.

Restoration of dry tropical forests in Central America: A review of pattern and process

Background

Much information on restoration and management exists for wet tropical forests of Central America but comparatively little work has been done in the dry forests of this region. Such information is critical for reforestation efforts that are now occurring throughout Central America. This paper describes processes of degradation due to land use and provides a conceptual framework for the restoration of dry tropical forest, of which less than 2% remains intact.

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).

Tropical rainforest regeneration in an area degraded by mining in Mato Grosso State, Brazil

Background

Gold mining has been a major cause of environmental degradation in the rainforests in the north of Mato Grosso State, Brazil. Regulations on mining activity are beginning to be developed, including standards for forest recovery methodologies. This study characterizes natural tropical rainforest regeneration in Matupa County, Mato Grosso State, Brazil.
