PILOT MANAGEMENT More than 6,000 acres of secondary stands in the Luquillo Experimental Forest have been subjected to systematic management to increase productivity. During 1961, the sixth year of such management, the first improve- ment cutting was completed in all but a small area to be acquired by a land exchange. In addition, during the cycle 91 acres were re- forested and 838 acres of plantations were released. Preparatory to the next treatment of this forest a field inventory was completed during 1961 which, when fully analyzed, will be used to determine the type and priority of further silvicultural work in the various compart- ments. Field data were also collected to determine the abundance and quality of na- tural regeneration resulting from the first treatment. Results, not yet complete, indicate that natural regeneration is generally ade- quate in quantity, but the better species are not always well represented. Other recent data on artificial regeneration and the poten- tial utility of a number of native woods will be used in drawing up the second management plan for this area during the coming Figure 2.
