Abstract

This study is an initial proposal for restoring the area knows as the Diques (flooded area) of the Reventado River National Reserve, Cartago, Costa Rica. For this it was used the software ArcGIS 9.3 to conduct the photo interpretation and map digitization. The main orthophotomaps sheets used in this study where Ochomogo 3445- IV-17 and Tejar 3445-IV-22, scale 1:10 000, and acquired by the Greater Metropolitan Area PRUGAM Project for land use zoning. Different land uses were identified within the study area of 129.7 ha such as: grasses (51.5%), urban (50.4%), secondary forest (18.2%), forest plantations (7.3%), extraction of materials such as stone and sand (1.9%) and runway model airplane (0.7%). A potential area of 45.15 hectares was identified for restoration with three tree suitable species for reforestation such as Citharexylum donnell-smithii (Dama), Acnistus arborescens (Güitite) and Acacia angustissima (Carboncillo) with densities of 100 trees / ha.
