The Effect of a Teak (Tectona grandis) Plantation on the Establishment of Native Species in an Abandoned Pasture in Costa Rica

background

This study compares native tree species recruitment in the understory of a 10-year-old teak plantation in premontane wet forest in Costa Rica to the native tree species recruitment on nearby abandoned agricultural land.

Manual of Reforestation and Erosion Control for the Philippines

background

This manual provides a detailed guide to reforestation, including information about species selection, nursery techniques, site preparation and plantation design, weed and fire control, stand improvement and other practical aspects of establishing and managing tree plantations. Additionally, there is a large portion devoted to erosion control, using trees and engineered structures to stabilize slopes and decrease the velocity of water runoff.

Indigenous Trees in West African Forest Plantations: The Need for Domestication by Clonal Techniques

background

This study evaluates native species tree plantations across West Africa by summarizing existing information on the yield of those plantations, with particular focus on the Cameroon Forest Management and Regeneration Project. It considers the potential for vegetative propagation and clonal selection to increase growth rates and marketability of native species.

Designing Mixed Species Tree Plantations for the Tropics: Balancing Ecological Attributes of Species with Landholder Preferences in the Philippines

background

This paper reports on the assessment of forest stands planted as part of the Rainforestation Farming Program and the management of plantations by local landowners regarding the original intent of planting.

Development of the Soil Macrofauna Community under Silvopastoral and Agrosilvicultural Systems in Amazonia

Background

This study seeks to analyze the effect that different agroforestry systems have on the recolonization of macrofauna in the soil of former pasture lands.

Development of the soil macrofauna community under silvopastoral and agrosilvicultural systems in Amazonia

Background

The Brazilian Amazon has experienced extensive land conversion from forests to cattle pasture, many of which now lay abandoned. Agro-forestry serves as one potential solution to this problem and this study examines the re-establishment of a diversified soil macrofauna in order to inform this approach.

Promoting Biodiversity: Advances in Evaluating Native Species for Reforestation

background

This article describes the design of a long-term species screening trial conducted at La Selva Biological Station in Costa Rica.

Research Goals & Methods

Growth and survivability data is presented for 84 species (17 popular exotics used for timber and 67 little-known local species with timber potential) at 3 years of age.

Early Species Selection for Tropical Reforestation: A Consideration of Stability

background

This study describes a screening of timber species planted in abandoned pasture sites to understand the effect of different site conditions on tree growth and to determine the species that grew with the highest variation.

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.

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.

Impact of Forest Management on Insect Abundance and Damage in a Lowland Tropical Forest in Southern Cameroon

Background

A burgeoning timber industry in Cameroon, which became the fifth largest producer of timber in the world in the 1990’s, led to unsustainably high deforestation rates and high demand for forest regeneration interventions. Research in the Mbalmayo Forest Reserve in southern Cameroon has compared different silvicultural techniques for forest regeneration including complete and partial clearance methods.
