DescriptionAbout 2400 individual stems > 4.1 cm d.b.h., and representing about 100 species, from six plots in three Life Zones, some with edaphic variationand/orsilviculturaltreatment, scattered throughout Puerto Rico, were studied for varying periods, usually ranging from 24 through 30 years but in one instance for only 2 years. Also, more than 11,000 mangrove stems > 1 cm at ground level were followed after clearcutting on 3 plots consisting of two separate treatments and a control. The periodic annual increment for all stems > 4.1 cm, regardless of species or crown class, ranged from about 0.05 cm/yr in the Guanica dry limestone forest of the southwest (Subtropical Dry Life Zone) to about 0.45 cm/yr in the Piiiones mangrove and early secondary rainforest at Saint Just, both in Subtropical Moist Life Zone. The species diversity of forests in Puerto Rico is intermediate between those of continental temperate forests of the United States and continental tropical forests. Ten species ac- counted for 70 to 95 percent of the stems on all sites, exclusive of Pinones mangrove and Guanica.
