Santa Rosa Sector in the Área de Conservación Guanacaste (ACG) is defined as Tropical Dry Forest, characterized by a long dry season (six to seven months), vegetation that loses its leaves in the dry season, and scarce water resources. Santa Rosa is a matrix of different stages of dry forest regeneration along with a series of patches of mature forest made up of pre-hispanic dry forest species which act as a seed bank for the natural regeneration of the forest. This sector is characterized as an important site symbolic to Costa Ricans. 

Found here are the administrative offices of the ACG, offices of the Biological Education Progam, Ecotourism and Research Programs, and the Center for Tropical Dry Forest Research.
