SUMMARY
A forest inventory of the Toro Negro region, Puerto Rico, was conducted in 1983. Eight different forest classes were sampled: active coffee shade, abandoned coffee shade, secondary forest, eucalyptus plantation , other timberland, upper mountain forest, palm forest, and dwarf forest. The study found the region is 61 percent forested with 20,100 hectares of timberland and 2,300 hectares of other forest land. Eucalyptus robusta accounts for 19,000 cubic meters or 37 percent of the growing - stock volume in the public forest. Seven valuable hardwood species add 16,000 cubic meters to the growing stock on public timberland. Private timberland also includes valuable timber, but the large trees are more scattered and the average volume is only one- third of that in public forests. Most eucalyptus plantations are ready for harvest and regeneration. Other public timberland contains good sapling and poletimber stocking and would benefit from release cutting. Private timberland has adequate sapling stocking, which could be released in many cases by removal of rough and rotten overstory trees.
