In the Biosphere Reserve Peninsula de Guanahacabibes, plant species are mainly used as food, medicine, honeybee feeders and timber. They are collected by folk people in the nearby forests but these collections can be a severe threat to many of the extant plant resources. An ethnobotanical study and a tree inventory were carried out in the 80 plots of the Unidad Silvícola El Valle in order to define a basis for the management and sustainable development of the useful species of the localities La Bajada, El Valle y Vallecito in the BRPG. Informal and structured interviews were made to 200 collectors as well as participant observations and hiking tours from October 1987 to September 2007. Results show that most useful plants are found in the lowland tropical forest, the seashore scrub thicket and the sandy and rocky coasts. Areas with least diversity are found in the northern zone where mangrove forests are dominant with two species: Avicennia germinans and Rhizophora mangle. Plot 15 has the largest amount of species (249). Over 200 species were found in the plots 73 (232), 70 (232), 80 (232), 68 (229), 74 (229) and 78 (229) where the following species are dominant: Gerascanthus gerascanthoides, Oxandra lanceolata and Sideroxylon foetidissimum subsp. foetidissimum.. According to the inventory, Talipariti elatum is abundant and therefore the controlled exploitation of its flowers is recommended for the production of green dye and medicine against colds. The propagation of pioneer species like Chrysobalanus icaco, Chrysophyllum oliviforme and Genipa americana during the first years of forest regeneration, followed by the propagation of foliage trees like Oxandra lanceolata (useful in the perfume industry) and Crescentia cujete will help to recuperate and/or restore the original forests.
