Book excerpt: Excerpt from The Caribbean Forester, Vol. 16: January-June 1955 The humid limestone region, extending al most the length of the north coast of Puerto Rico, is an area of shallow rocky clay soils, mostly hilly and already covered with secon dary forests. The lower, more protected slo pes apparently are potentially a good forest site, but because of their accessibility few trees of good species remain. Reforestation is less a problem than the introduction of supe rior species into existing stands. The studies here reported are located in the Cambalache Experimental Forest at sea level with about 60 inches of rainfall annually, in the Rio Aba jo Forest, at feet elevation with 80 inches of precipitation, and in the Guajataca Forest at 500 feet elevation with 70 inches of rain fall annually.made slow but continuous growth beneath light shade. After 2 years the trees range between 30 and 48 inches in height, and no need for early liberation is apparent. Mexican cypress (cupressus lusitanica Mill), described elsewhere in this report as very promising at high elevation, has general ly appeared much less adapted to low eleva tions. Trees at sea level usually become poorly formed, weaken, and frequently fall over. In 1952 underplanting in the Rio Abajo forest the trees appeared so weak until the past year as to be destined for failure. However, as a result of recent complete liberation from shade the trees now appear to be growing as well as at higher elevations. Now, after 4 years, the trees range between 10 and 15 feet in height and are beginning to dominate the site. This species will apparently not withstand much shade under these conditions and therefore should not be underplanted.
