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.

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. La mezcla de especies mostro la mayor productividad volumétrica, estadísticamente superior a las especies en plantaciones puras. Open access copy available |

Silvicultural and economic aspects of pure and mixed native tree species plantations on degraded pasturelands in humid Costa RicaBackgroundReforestation 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. Available with subscription or purchase |
Strategies for the Recovery of Degraded Ecosystems: Experiences from Latin AmericabackgroundThis paper reviews the rehabilitation potential of native species forest plantations in lowland Costa Rica, the Atlantic Forest of Bahia, Brazil, and sub-tropical Argentina. Native species can improve forest regeneration where soils are degraded and where sources of propagules are limited. While most tropical plantations are dominated by exotic species, native trees may be more appropriate because they are better adapted to the local environment, are already familiar to local farmers, and their propagules are locally available.

Forest Plantations in Costa Rica and Nicaragua: Performance of Species and Preferences of FarmersbackgroundThis paper presents data on the survival and growth of mixed native and exotic forest plantations established on abandoned pastures in Costa Rica and Nicaragua. The article also includes information on farmer species preference and socioeconomic information. Open access copy available |
Early Growth of Native and Exotic Trees Planted on Degraded Tropical PasturebackgroundThis study describes the potential of two exotic and five native tree species to restore degraded land in Costa Rica. Research Goals & MethodsThirty 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.

Growth and effects of thinning of mixed and pure plantations with native trees in humid tropical Costa RicaBackgroundAs 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. Open access copy available |
Attempting Restoration of Wet Tropical Forests in Costa RicaBackgroundThis article describes a reforestation effort of the Tropical Forestry Initiative using mixed stands of native species to recover abandoned pastureland in the tropical wet forest of Costa Rica.
