The Conservancy has been working since 1991 with partner Fundación Natura to protect the last remains of oak forests in the Andean region of Colombia. As part of this effort, the Conservancy supported the creation of the 3,212-acre Cachalú Reserve and 25,748-acre Guanenta Alto Rio Fonce Fauna and Flora Sanctuary. The Conservancy is currently launching an unprecedented effort to protect 2.5 million acres of Andean landscapes that include oak forests, páramos (high altitude grasslands), and cloud forests linking these and other protected areas to create the Oak Forests Conservation Corridor.
Location
The Oak Forests Conservation Corridor is located in the easternmost branch of the Colombian Andes range in the departments of Boyacá and Santander in northwestern Colombia. It includes 67 municipalities and encompasses 2,545,185 acres.
Animals
The corridor harbors populations of several endangered mammals such as the spectacled bear (Tremarctos ornatus), wolly tapir (Tapirus pinchaque), brown hairy dwarf porcupine (Sphiggurus vestitus) and puma (Puma concolor). The corridor has 50 mammal species, 12 of which are endangered.
The corridor also has 243 bird species, including the critically-endangered gorgeted wood-quail, black Inca and mountain grackle. Several North American migratory birds, such as the blackburnian warbler, mourning warbler and Swainson's thrush, winter in this area.
The corridor is also home to two endangered frog species, the endemic Gámbita robber frog (Eleutherodactylus spilogaster) and sharp-snout robber frog (Eleutherodactylus acutirostris).
Plants
The Oak Forests Conservation Corridor is one of the richest areas in terms of vascular plants in the Andean region. The Cachalú Reserve alone has more than 400 different plant species. The dominant species in the area is the Humbolt oak (Quercus sp), black oaks (Trigonobalanus sp.), carisecos (Billia sp.), higuerones (Ficus sp.), and yarumos (Cecropia sp.) among others. Epiphytes are quite common, especially orchids, bromeliads and ferns. In the high-altitude grasslands the dominant plant is the frailejón (Espeletia spp.)
Why the Conservancy Works Here
The Andean region is one of the most highly impacted areas in Colombia. Seventy percent of the country’s population lives here, and pressures such as unsustainable agriculture and livestock expansion cause great stress on natural ecosystems. The Andes region is one of the most biologically diverse areas on Earth—it has about the same number of animal and plant species as the entire Amazon region, but in an area 14 times smaller. Also, the Colombian Andes maintain one of the last remnants of oak forests in South America.
What the Conservancy Is Doing
With its partners, the Conservancy recently implemented a Conservation Area Planning (CAP) analysis that evaluated threats, opportunities and places that must be conserved to ensure the diversity of the Oak Forests Conservation Corridor. As a result of this study, the Conservancy is currently supporting the following:
