Dinira National Park was created in 1988 in order to protect the upper basins of the Tocuyo, Chabasquén, and Boconó rivers, whose waters are essential to the development of Venezuela´s central-western region. The name, "Dinira" is derived from the Arawaco indigenous word, "Dinta" which means hills in the form of breasts--alluding to their ability to provide life and vitality. Their location, in the Andean foothills, as well as their peculiar geography--hills and rugged, high mountains--create a unique climate in the region where low temperatures and páramo vegetation dominate. In addition to Dinira's particular geomorphology, it is also an important refuge for fossilized archeological remains.
Although the park's fauna and flora are not entirely known, it is believed that certain endangered species reside in Dinira, including the spectacled bear (Tremarctos ornatus) and the helmeted curassow (Pauxi pauxi). Lara State's only páramos are found in Dinira and because this vegetation is isolated from the rest of the country's páramos (in Trujillo and Mérida), it is quite possible that they have elevated levels of endemism. Some endemic plant species have been described, including the carnivorous plant Drosera cendeensis (Crespo 1999).
Dinira National Park is in very good condition, and along with Guaramacal, is perhaps one of the best-preserved parks in the country. Dinira is so well maintained because of the lack of serious pressures in the surrounding areas and lack of access routes. Nonetheless, some problems such as lack of staff and control measures could eventually reduce Dinira's effectiveness as a tool to protect biodiversity and watersheds. Therefore, Dinira is considered vulnerable.
