    Description

    The principal findings of the second forest survey of Puerto Rico (1990) and changes that have occurred since the survey was established in 1980 are presented. The forest inventory estimates describe the timber resource found within the potential commercial region designated in the first survey. The timber resource addressed consists primarily of regrown areas on abandoned pastures and cropland, including coffee production areas. The status and trends of the timber resource are presented for the two Life Zones occurring in the commercial region, as well as for various forest classes, which are based on stand history and origin. Topics discussed include forest area, timberland area, basal area, species composition, timber volume, growing-stock volume, and sawtimber volume. Results of the 1990 survey are promising, showing increases in numbers of trees across all diameter classes and substantial increases in volume. These trends offer evidence that Puerto Rico’s forests are continuing to recover following a dramatic decline of the late 191h and early 20’h centuries.
