Located in the western central part of the country, Pacífico central Conservation Area (ACOPAC) encompasses the land between the community of Manzanillo, in the extreme north of the province of Puntarenas to the Barú River in the canton of Aguirre and intermediate lands in the southwest of the Central Valley and part of the land of high mountains in the Talamanca Mountain Range.
ACOPAC represents 11% of the country (562.552 ha). It is a region full of contrasts because of its varied terrain, diverse climate, biodiversity and historical patterns of colonization. 16 of the 34 most important Watersheds of Costa Rica converge within it, 11 of the 12 life zones, 7 of the 9 transitions and presents the 6 altitudes where the country is divided. Furthermore, in ACOPAC are the hills of Turrubares, which together with the floors of Bahia Salinas in Guanacaste, were the first points to emerge from the seabed to form the Costa Rican territory.
For the territory of ACOPAC there are reported 5640 species of plants from almost 90 million collected for our country, figure that corresponds to 62.7%, according from the National Museum data and the National Biodiversity Institute. The average levels for this conservation area is 1014 species per 1000 km2, being 5.76 times higher than the average reported for all Costa Rica, reaching the 176 species per 1000 km2 plants. Of the approximately 10,000 endemic species to the country, they are reported to ACOPAC 5000, and over 76% of the timber species in danger of extinction. In addition, 201 species of 238 mammals existing in Costa Rica, among which 4 species of primates reported to Mesoamerica, the 6 species of big cats and the largest in the neotropical area (Panthera onca), like the tapir, which represents the largest wild terrestrial mammal reported for this country.
In ACOPAC, there present 746 bird species representing 83.6% of the 892 set for Costa Rica, more than 14 thousand species of lepidoptera and 11 of the 18 endemic species of freshwater fish.
Within it there are important ecosystems as mangroves, high Andean plateaus located further north of the planet, Las Turberas which have been declared RAMSAR site as historical data, it is important that ACOPAC protects the first national park declared for our country (Robledales National Park, established in 1945) and the most recent statement National Park (Quetzales national Park, decreed in 2006).
In short, ACOPAC hosts 60% of flora and over 70% of mammals, birds and Lepidoptera of the country.
