A series of properties were purchased to form a continuous block of biodiversity of 120,000 terrestrial hectares and 70,000 marine hectares, in which there exist approximately 230,000 species (65% of the estimated number of species in Costa Rica). The Area de Conservación Guanacaste has 10 years experience in searching for and making a model based on a tropical reality which would permit the conservation of biodiversity by means of non-damaging use by society. The ACG, is one of the eleven Areas of Conservation that make up the Sistema Nacional de Areas de Conservación (SINAC) (National System of Conservation Areas), of the Ministerio del Ambiente y Energía (MINAE) (Ministry of the Environment and Energy) of the Costa Rican government.
In response to the new policies of the Ministry of Environment and Energy, of decentralizing functions and responsibilities, the ACG has increased its responsibilities to add the Agricultural Landscape (Agroscape) Area , whose management objectives are different from those of the ACG. This is a new step for the ACG, in which we have to develop the experience, human resources and the financial resources necessary to accomplish the objectives of the Agro landscape Area.
