The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa Rica

background

This study analyzes the understory recruitment success of tropical timber plantations in order to understand biodiversity recovery on degraded lands through the use of fast-growing timber plantations. The study takes place in the Atlantic humid lowlands of Costa Rica.

Early Woody Invasion Under Tree Plantations in Costa Rica: Implications for Forest Restoration

Background

This study evaluates the regeneration of woody plants, the amount of herbaceous cover, and the light conditions in the understory of 3-year-old mixed and single-species plantations in Costa Rica.

Influence of Overstory Composition on Understory Colonization by Native Species in Plantations on a Degraded Tropical Site

background

This study evaluates forest understory regeneration in a 4.5 year-old plantation in Puerto Rico. The plantations, established in 1989, were planted on abandoned pasture in mixtures or monocultures of three exotic species: Casuarina equisetifolia, Eucalyptus robusta, and Leucaena leucocephala.

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.

Direct Seeding of Late-Successional Trees to Restore Tropical Montane Forest

background

This study measures seed germination, seedling establishment, survival, growth and foliar nutrient content of five late-successional tree species which were directly seeded into three different habitats representing different stages of succession in tropical montane Costa Rica.The study also compares the costs of direct seeding with locally collected seeds with planting nursery-raised seedlings.

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.

Screening Trial of 14 Tropical Hardwoods with an Emphasis on Species Native to Costa Rica: Fourth Year Results

Background

A lack of silvicultural information on native timber species in the tropics has contributed to the propogation of fast-growing exotic tree species in reforestation efforts. The plantations evaluated at the La Selva Biological Station in Costa Rica were considered marginal lands with low input of forest maintenance, reflecting the conditions of many lands that farmers would use for reforestation.
