Maquenque National Wildlife Refuge


Maquenque Wildlife Refuge, is a protected area in Costa Rica, managed under the Arenal Huetar Norte Conservation Area, it was created in 2005 by decree 32405-MINAE.
It connects Tortuguero National Park and La Selva Biological Station in the Cordillera Central in Costa Rica, with the Barra del Colorado Wildlife Refuge, the Indio-Maíz Biological Reserve, Punta Gorda Natural Reserve and the Cerro Silva Natural Reserve in Nicaragua, thereby allowing animals to move between the regions. This region is now known as the San Juan-La Selva Biological Corridor, located between the San Carlos River and the Sarapiquí River and other areas near the Nicaraguan border.
The nearest towns and villages are Puerto Viejo de Sarapiquí and Pital.

History

The refuge was created in 2005 from existing reserves such as El Jardín Hill Forest Reserve, Cureña Forest Reserve, Laguna Maquenque Wetlands and the Tamborcito Lacustrine Wetlands, which were deprecated and assimilated into the current refuge.
In 1998 a number of ornithologists proposed creating a new national park in this area, in order to help link other existing neighbouring areas in Costa Rica and Nicaragua, and thus protect the great green macaw population. Instead, the Costa Rican government created a wildlife refuge in 2005.
The concept of this area as a biological corridor was already proposed in 1985 by the first revolutionary Sandinista government as the "Sistema Internacional de Areas Protegidas para la Paz". It became Ramsar Site 1918 in 2010. The area is administratively part of the Arenal Huetar Norte Conservation Area.

Habitats

It features a very wet, non-seasonal, evergreen rainforest environment with a yearly precipitation of 3,000-3,600mm. 70.21% is primary forest, 6.17% is secondary forest or scrubland, and 20.13% is devoted to agriculture. There are many epiphytes, vines and climbing plants, and a dense understory.
The reserve included wetlands and protected an example of the virgin tropical moist forest that once blanketed the territory alongside the San Juan River.
It also has a lake complex and palustrine ecosystems. The lake complex consists of at least four major lakes: Canacas, Colpachi, Maquenque and Tamborcito.

Species

Flora

The permanently inundated swamps are home to stands of the palm Raphia taedigera and are surrounded by thickets of melastomataceae. Other plants associated with this habitat are the trees Vochysia ferruginea and Pentaclethra macroloba and the palm Socratea exorrhiza. Pachira aquatica grows in this habitat in more inland swamps. Zygia confusa borders lakes in dense stands. Dry land contains large amounts of almendro trees, a favoured food source of the great green macaw, which may grow to 60m high. Another emergent tree is Ceiba pentandra. Other common trees here are Calophyllum brasiliense, Vochysia ferruginea, Pentaclethra macroloba and the palm Socratea exorrhiza.

Socioeconomic activities

The nearby town of Boca Tapada in Pital, has an abundance of ecolodges,.
Land surrounding the area is either wooded or used for agriculture. Cattle ranching is important, as are hundreds of pineapple and sugar cane plantations. Other crops are bananas, heart of palm, plantains and cassava. Due to the wildlife refuge status, development is restricted for the residents.
