In January 2002 an experimental fire was carried out on a mature Pinus tropicalis forest in the Guaniguanico Mountain Range W Cuba . Three permanent plots were set and vegetation composition and structure was studied before and one year after fire. The ecological parameters considered were floristic richness diversity abundance life forms and reproductive strategies of the vegetation. Results showed an increase in floristic richness and abundance of several species. Three endemic species appeared after fire and changes in life form rates were recorded although pine regeneration was poor. Seeders showed a significant decrease and the number of phanerophyte species with both strategies seedling and sprouting increased. Results suggest that fire can be used as a tool to prevent great forest fires if avoiding soil losses and the status of surrounding vegetation is taken into consideration.
