Amelioration of degraded rain forest soils by plantations of native treesbackgroundWhile much has been studied about the ability of tree growth to improve degraded soils in temperate zones, less is known about the impacts of tree growth on degraded soils in tropical zones.

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

The Role of Native Species Plantations in Recovery of Understory Woody Diversity in Degraded Pasturelands of Costa RicabackgroundThis 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. Open access copy available |

Early Growth Performance of Native and Introduced Fast Growing Tree Species in Wet to Sub-Humid Climates of the Southern Region of Costa RicabackgroundThe 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 & MethodsThe study evalutes trees in four ecoregions of varying elevation and precipitation. Available with subscription or purchase |
Native Species: A Resource for the Diversification of Forestry Production in the Lowland Humid TropicsbackgroundThis research evaluates the success of native species for reforestation plantings in Costa Rica in comparison with exotic species. Available with subscription or purchase |
Woody Understory Plant Diversity in Pure and Mixed Native Tree Plantations at La Selva Biological Station, Costa RicaBackgroundThis 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.

Restauración ecológica de bosques tropicales en Costa Rica: efecto de varios modelos en la producción, acumulación y descomposición de hojarasca
EspañolAntecedentesEste estudio se llevó a cabo en Coto Brus, y se enfoca en la restauración de paisajes agrícolas fragmentados dentro del Corredor Biológico Amistosa. El mismo es un área prioritaria para la forestería y la conservación en Costa Rica que ha sido degradrada y transformada por la expansión agrícola durante los pasados 50 años, dejando solo un 25% del bosque original.

Tree species effects on soil properties in experimental plantations in tropical moist forestBackgroundForest soil properties are influenced by the complex interactions of vegetation, soil type, geology, management, and climactic patterns. Tree species can differ in their long-term effects on soils. This study resamples one of the earliest replicated experimental sites at La Selva Biological Station, Costa Rica, used to examine the effects of native tropical tree species on soil properties, to examine longer term effects on soil properties.

Patch Size Effects on Avian Foraging Behaviour: Implications for Tropical Forest Restoration DesignbackgroundThis study looks at bird behavior in restoration sites in southern Costa Rica. While multiple studies examine the presence of birds in restored forest, few studies examine behavior in these sites. Open access copy available |
Migratory Bird Species in Young Tropical Forest Restoration Sites: Effects of Vegetation Height, Planting Design, and SeasonbackgroundThis study examines the difference in habitat preference of four migratory birds in restored forests in southern Costa Rica. Open access copy available |
