Sustainable Development and Wild Nature Conservation in NICARAGUA

Laguna de Apoyo (Lake Apoyo) is Nicaragua's largest volcanic crater lake. It was formed 23,000 years ago after
a huge volcanic explosion left a large crater which interrupted the underground water table. Today, the lake is 180 meters deep and four
kilometers in diameter. Its clear water is always warm, never below 28 degrees Celsius (great for swimming!).
In Nicaragua, the term "laguna" is given to the volcanic crater lakes which are found in some of the volcanoes along the Pacific region
of the country.

Laguna de Apoyo and the crater in which is it located were named the Laguna de Apoyo Nature
Reserve as an official
protected area in 1991, by Decreto 42-91 in the National Assembly. However, until recently, this site has never enjoyed
the full benefits of protection that would be afforded this designation.
Laguna de Apoyo worked closely with the another Nicaraguan
organization, Liga de Cooperativas de Nicaragua (CLUSA), in the development of its first
commissioned and approved by the Nicaraguan Ministry of Natural Resources and the Environment.
GAIA directed biodiversity
studies and coordinated consensus-building activities with the various interest groups involved as part of the management plan development,
and developed a set of 35 maps
demarcating the reserve boundaries, land use patterns, risk assessments, wildlife, and tourism potential.

Laguna de Apoyo is a special place, not only for its amazing views of the lake from near and far. The water of
Laguna de Apoyo is home for six endemic species of cichlid fishes. The GAIA research group working at
Estación Biológica Laguna de Apoyo discovered five of these
species, and we are continuing research on the evolutionary history, ecology, and conservation aspects of these fishes. One fish species in Lake Apoyo,
the arrow cichlid (Amphilophus zaliosus), is listed as Critically Endangered on the IUCN Red List, and other species may soon follow.

Other species of fishes found in Laguna de Apoyo are: Amphilophus astorquii, Amphilophus chancho,
Amphilophus flaveolus, Amphilophus globosus, Amphilophus supercilius, Parachromis managuensis, Atherinella sardina,
and Poecilia sphenops.

Laguna de Apoyo is facing severe threats to its continued existence as a beautiful, natural lake.
Although Laguna de Apoyo Nature Reserve is located between two of the most populous cities in Nicaragua (Masaya and Granada), the
reserve continues to contain substantial quantities
of natural forest and a huge lake in very good condition. Nonetheless, housing developments, trash, deforestation, and invasive species
all threaten Lake Apoyo and its special inhabitants.
