El Dorado Nature Reserve was established in January 2006 and
currently protects a 1,729 acre block of the last remaining
tropical forest on the northwest slope of the Sierra Nevada de
Santa Marta massif on Colombia’s Caribbean coast. It is owned
and managed by Fundación ProAves and forms part of the Santa
Marta Alliance for Zero Extinction (AZE) site. Our goal is to
increase the reserve size to 6,900 acres. The Sierra Nevada de
Santa Marta is an ancient and isolated massif that is separated
from and pre-dates the Andes. Although smaller than U.S. the
state of Connecticut, these mountains contain the single highest
concentration of endemic birds found on the planet and more
resident bird species than the continental USA. It is home to 19
bird species endemic to the Sierra Nevada de Santa Marta, of
which nine are endangered, and seven endangered species of
amphibians including two Critically Endangered species, the
Stubfoot Toad (Atelopus nahumae) and a species of harlequin frog
(Atelopus laetissimus). Prelimin
