Abstract:

Distributions of land cover and forest formations for Puerto Rico, Vieques and Culebra were mapped from previously published Landsat satellite image mosaics dated 1991 and 2000. This file is the map of land cover and forest formations for about the year 1991 for Puerto Rico, Vieques and Culebra, but it differentiates cloud forest into two classes using data from Helmer et al., 2002, Caribbean J. Science 38(3-4):165-183. Important notes: 1. Open drought deciduous woodlands, with 25 to 60% woody vegetation cover, are grouped with pasture in the version of this map that is generalized to land cover. 2. Low density urban lands are included with the Urban class and may have as little as 10-15% urban/built-up lands. 3. Errors from minor misregristration between the maps from 1991-2000 will cause some error in analyses of change. 4. We recommend using urban change data from Helmer and Ruefenacht (2005) to estimate urban change from 1991-2000. On the Caribbean island of Puerto Rico, forest, urban/built-up and pasture lands have replaced most formerly cultivated lands. The extent and age distribution of each forest type that undergoes land development, however, is unknown. This study assembles a time series of four land-cover maps for Puerto Rico. The time series includes two digitized paper maps of land cover in 1951 and 1978 that are based on photo interpretation. The other two maps are of forest type and land cover and are based on decision tree classification of Landsat image mosaics dated 1991 and 2000. With the map time series we quantify land-cover changes from 1951 to 2000; map forest age classes in 1991 and 2000; and quantify the forest that undergoes land development (urban development or surface mining) from 1991 to 2000 by forest type and age. This step relies on intersecting a map of land development from 1991-2000 (from the same satellite imagery) with the forest age and type maps. Land-cover changes from 1991-2000 that continue prior trends include urban expansion and transition of sugar cane, pineapple and other lowland agriculture to pasture. Forest recovery continues, but it has slowed. Emergent and forested wetland area increased between 1977 and 2000. Sun coffee cultivation appears to have increased slightly. Most of the forests cleared for land development, 55 percent, were young (1-13 yr). Only 13 percent of the developed forest was older (41-55+ yr). However, older forest on rugged karst lands that long ago reforested is vulnerable to land development if it is close to an urban center and unprotected.
