Publisher: (Mar-Ago 2010)ISSN: 1659-1216.Other Title: Land cover dynamics and priority areas for forest restoration in the Caribbean region of Costa Rica.Subject(s): BOSQUES | REHABILITACION FORESTAL | SUELO | PLANTACION FORESTAL | BOSQUE VIRGEN | CARIBE | COSTA RICAOnline Resources: Es In: Recursos Naturales y Ambiente (CATIE) no. 59-60 p. 99-107Summary: Este trabajo buscó calcular el potencial de restauración forestal y definir áreas a restaurar en una zona de mucho dinamismo de uso del suelo en la región Caribe de Costa Rica. Se clasificó el uso del suelo y se analizaron los cambios a partir de imágenes Landsat TM durante los periodos 1986-1996 y 1996-2006. Se creó un modelo del potencial de restauración forestal basándose en las variables presencia ó ausencia de bosque y de espacios naturales protegidos, y riesgo de inundaciones. El bosque natural mantuvo la superficie inicial. Las plantaciones forestales con especies nativas fueron una opción importante para recuperar sitios deforestados durante la década del 86-96, pero no en el periodo 1996-2006. Los pastos arbolados y plantaciones forestales cedieron terreno a las actividades agrícolas y ganaderas. El potencial de restauración forestal se estimó en 251.472 haSummary: de estas, 42.594 ha y 3.328 ha, fueron clasificadas como de prioridad crítica y máxima, respectivamente.Summary: This work was intended to calculate the forestry restoration potential and to determine priority areas to be restored within a dynamic land use area in the Costa Rican Caribbean Region. A land use classification was developed and land use changes analyzed using Landsat TM satellite images during the periods of 1986-1996 and 1996- 2006. A forestry restoration potential model was created distinguishing between critical, maximum, intermediate and low priority areas. The model was based on variables such as presence/absence of forest cover and protected areas, and flooding risks. Natural forests maintained its initial surface throughout the analyzed period. Forest plantations with native species were important to restore deforested sites during the decade of 1986-1996, but not during 1996-2006. Shaded pastures and forest plantations decreased while agriculture and open pasture areas increased. The forestry restoration potential was estimated in 251.472 ha: 42,594 ha and 3,328 ha were classified as critical and maximum priority, respectively.
