Cuilco is an important site for range-restricted birds of the North Central American Highlands and for biome-restricted species of the Madrean Highlands and Pacific Arid Slope. The site supports populations of two globally threatened species: Highland Guan and Pink-headed Warbler. Coffee and corn plantations cover about 30% of the IBA. The IBA is entirely unprotected.
Consejo Nacional de Areas Protegidas (CONAP) - Solola supported a workshop to identify IBAs in June 2006, hosted by Universidad del Valle (Altiplano) in Solola. Input of unpublished data and suggestions for the delimitation of the IBA was provided during this workshop by representatives of CONAP, Universidad del Valle - Altiplano, Fundación para el Ecodesarrollo y la Conservación (FUNDAECO) - Huehuetenango, Ministerio de Agricultura, Ganadería y Alimentación de Guatemala (MAGA) - Solola, Cuerpo de Paz, Municipality of Tecpan, Autoridad para el Manejo Sustentable de la Cuenca del Lago Atitlán y su Entorno (AMSCLAE), and Los Tarrales Nature Reserve. This first assessment of IBAs in Guatemala was conducted by Sociedad Guatemalteca de Ornitologia and BirdLife International in the Americas.
