Barriers to Lowland Tropical Forest Restoration in the Sierra Nevada de Santa Marta, Colombia

Background

This article examines the major barriers to forest restoration in the abandoned pastureland surrounding three forest fragments  in the Rio Rancheria watershed of the Sierra Nevada de Santa Marta in Colombia. These barriers include: seed source, seed predation, competition from grasses, microclimate, soil quality, and fire.

Applying Indigenous Knowledge to the Restoration of Degraded Tropical Rain Forest Clearings Dominated by Bracken Fern

background

The indigenous Lacandon Maya people of southern Mexico use a rotational agriculture system known in Spanish as the milpa for production of maize and other crops. This system rotates production to different plots, allowing the forest and soil to recover in the fallow years between production periods. In some cases, the Lacandon people actively manage forest recovery, sowing Balsa trees to prevent plots from being taken over by the invasive Bracken fern.

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.

Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa Rica

background

The authors present information on the growth of seven-year-old native tree species planted in abandoned pasture with low fertility acidic soils in the southern pacific region of Costa Rica.

Research Goals & Methods

The study evalutes trees in four ecoregions of varying elevation and precipitation.

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.

Growth characteristics of some native tree species used in silvopastoral systems in the humid lowlands of Costa Rica

Background

Degraded pastures established throughout Central America in the latter 20th C are gradually transitioning to silvopasture or secondary forest. Understanding growth characteristics of trees on these lands is important for proper management.

Woody Understory Plant Diversity in Pure and Mixed Native Tree Plantations at La Selva Biological Station, Costa Rica

Background

This study compares the species richness, abundance, and seed disperal method of individuals growing in the understory of native single-species plantations, native mixed-species plantations, and naturally regenerating (non-planted) areas of the La Selva biological station in Costa Rica.

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.

Early Growth of Native and Exotic Trees Planted on Degraded Tropical Pasture

background

This study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica.

Research Goals & Methods

Thirty blocks were established over 25 hectares of abandoned cattle pasture and tree height was measured at 3 and 7 years and tree survival was measured after 7 years.
