Guanacaste Conservation Area: An Important Natural Habitat

The Guanacaste Conservation Area is a crucial natural habitat for biodiversity, protecting some of the world's best remaining dryland forest, the biomes stretching from Central America to northern Mexico, and many endangered plants and animals. Its terrestrial and coastal environments underpin essential ecological processes: the evolution, continuation, and restoration of the Pacific tropical dry forest; the uphill and seasonal migrations of wildlife and other ecological interactions; and the emergence and growth of coral colonies and reefs.

Heritage Number: 928

Geographic Location and Features

The Guanacaste Conservation Area lies in northwestern Costa Rica, stretching from the Pacific coast roughly 12 miles inland, across the Pacific lowlands, over three volcanoes, and back down to the lowlands on the far side — about 105 kilometers end to end. It was inscribed as a UNESCO World Natural Heritage site in 1999. The reserve covers 88,000 hectares of land and 43,000 hectares of sea, figures that do not include a further 3,000 to 5,000 hectares later folded into the protected area. Its highest point reaches 1,916 meters.

The area encompasses a chain of volcanic regions, the most prominent being Rincón de la Vieja Volcano, with three craters and a lagoon. Its most recent observed eruption came in the 1970s, though one crater still vents gas today. Thirty-two rivers and 16 hot springs rise near the volcano. The western terrain is built of carbonate rocks while the coast is mainly sedimentary, with saline lagoons common along the beaches.

The climate is hot, with a long rainy season from May to October, annual precipitation of up to 1,528 millimeters, and an average annual temperature of 28°C. April and May are the hottest months.

Natural Geography

The Guanacaste Mountain Range (Cordillera de Guanacaste) runs through northwestern Costa Rica as part of the continental divide. Oriented northwest to southeast, it extends 113 kilometers (70 miles) and tops out at 2,020 meters (6,627 feet). In 1968, Arenal Volcano erupted, blanketing the entire region in ash, destroying pastures, and killing 100,000 cattle.

The conservation area sits in Central America at roughly 10°N latitude and 84°W longitude, bordered by the Caribbean Sea to the east and the North Pacific to the west, with 1,290 kilometers of coastline — 212 kilometers on the Caribbean side and 1,016 kilometers on the Pacific. It shares a 309-kilometer border with Nicaragua to the north and a 639-kilometer border with Panama to the southeast.

Geological Formation

The strata here are well developed from the pre-Mesozoic through the Mesozoic Triassic, but Jurassic, Cretaceous, and Cenozoic Tertiary strata are absent. The distribution divides roughly along the Picao River: Paleozoic strata dominate the southeast and Mesozoic Triassic strata the northwest.

Large exposures of Silurian Maoxian Group metaclastic rocks lie in the southeast — gray-green sericite phyllite and silver-gray sandy phyllite interbedded with thin quartzite layers and thin, lenticular crystalline limestone. Near the Picao River, Devonian and Carboniferous-Permian strata appear in strips: the former consisting of unmetamorphosed gray and dark-gray thin-bedded limestone and argillaceous limestone interbedded with carbonaceous slate and sandstone; the latter of medium-to-thick bedded limestone interbedded with phyllite, carbonaceous phyllite, and crystalline limestone interleaved with sandstone and conglomerate.

In the Sanjiangkou area, Ordovician gray medium-to-thick bedded feldspar quartz sandstone, quartz sandstone, and sandy slate are sporadically exposed. The northwest holds extensive Triassic strata — feldspar quartz sandstone, slate, carbonaceous phyllite, thin limestone, and fine siltstone. Devonian strata surface along the anticline axis as carbonaceous phyllite, sandy phyllite interbedded with quartzite, and clastic limestone. The Dengsheng area carries a small stretch of Carboniferous-Permian strata, mostly carbonaceous phyllite and crystalline limestone interbedded with sandstone.

Quaternary loose deposits include fluvial sediments, debris-flow deposits, and glacial till. Fluvial deposits concentrate in the Picao River valley and its tributaries; debris-flow deposits pile up at the mouths of gullies such as Huahongshugou, Longyangou, and Daweijiagou; ancient glacial deposits rest in the old glacial valleys of Xiangyangping on the upper Picao River and the upper Zhenghe River, while modern glacial deposits occupy the active glacial valleys.

Main Vegetation

The heart of the reserve's vegetation is the dryland forest covering roughly 60,000 hectares, where about twenty different biomes grow across varied soils and slopes. The main vegetation types include: (a) dominant mixed deciduous forest with scattered fig and mahogany trees; (b) evergreen forest along rivers and floodplains; (c) savanna dominated by Hyparrhenia rufa with sparse shrubbery; (d) oak forest and savanna containing Quercus species; and (e) mangrove forest, plus assorted beach plants.

Around Rincón de la Vieja Volcano, four distinct vegetation zones appear: first, tropical Quercus, sapodilla, and cedar trees clinging to barren, heavily eroded soils; second, assorted wetland plants; third, rainforest plants that shift with topography; and fourth, dwarf rainforest plants. Clouds shroud this forest year-round, and constant wind and poor soil keep the trees small. Eight species of mangrove grow in the area's mangrove forests, all well preserved.

Main Species

Records show that since 1973 the populations of vertebrates, insects, and aquatic animals within the reserve have steadily grown. The area shelters many species of conservation significance. Notable mammals include white-tailed deer, white-lipped peccaries, tapirs, white-faced monkeys, spider monkeys, howler monkeys, anteaters, jaguars, ocelots, and jaguarundis. More than 500 bird species live here, among the most common being macaws, American speckled quail, crested guan, blue-winged teal, herons, American storks, ibises, and falcons. Small numbers of caimans and American crocodiles have been found at the reserve's estuaries.

During the annual sea turtle mating season from October to December, over 250,000 sea turtles crowd the beaches — mostly olive ridley, green, leatherback, and hawksbill turtles. The area also hosts over 12,000 species of nematode insects, over 20,000 species of beetles, and over 13,000 species of bees.

Historical Significance and Tourism

The Santa Rosa Hacienda, built between 1580 and 1600, was among the region's earliest and largest cattle ranches. In 1856 it was the site of the Battle of Santa Rosa, and in 1966 Costa Rica celebrated its independence here. The hacienda began by raising mules for hauling goods; its pastures later shifted to cattle, and the beef fed workers from Nicaragua and Guatemala employed in local indigo factories.

Santa Rosa National Park is now the most popular attraction within the conservation area, drawing visitors to its historical monuments and to the sight of thousands of sea turtles gathered on the beaches. In 1997 the park received 64,000 visitors, half of them from within Costa Rica.

FrontStreet Coffee Recommendation

Costa Rica is the kind of origin worth exploring once this landscape has captured your imagination. The country grows coffee at high altitude with a wide day-night temperature swing and rich volcanic soil everywhere — conditions that produce abundant strictly hard bean (SHB grade) coffee of elegant aroma. What Costa Rica is best known for, though, is honey processing: the beans are dried with their mucilage still clinging to them, which loads the cup with sweetness and remarkable clarity of flavor. For a first taste of Costa Rican specialty coffee, FrontStreet Coffee recommends the black-honey-processed Blackberry, or the raisin-honey-processed Mozart, which brews up sweet notes of raisin and blueberry with the fragrance of osmanthus and rose. Whether you choose pour-over, cold brew, Americano, or latte, both beans show off the clean, honeyed sweetness that makes Costa Rican coffee so distinctive.
