Several studies on the biodiversity emphasized the conservation value of the Chelemhá cloud forest. Based on bird inventories (Eisermann & Schulz 2005, Renner et al. 2006), the Yalijux mountain range was designated as an Important Bird Area by BirdLife International (Eisermann & Avendaño 2009a,b).

PROEVAL RAXMU Bird Monitoring Program is studying the natural history of selected bird species in Chelemhá, including Guatemalan Pygmy-Owl.

PROEVAL RAXMU Bird Monitoring Program is studying the natural history of selected bird species such as Resplendent Quetzal, Highland Guan, and several owl species (Eisermann et al. 2006, Eisermann 2012, Eisermann 2013a,b, Eisermann & Howell 2011, Howell & Eisermann 2011).

Investigations on the Quetzal (Unger 1988, Mühlenberg et al. 1989) showed that Chelemhá is one of the sites with the highest density of Quetzals in Guatemala.

A study on the diversity of small mammals was published in 2014 (Matson et al. 2014).

Valuable specimens for the floristic inventory were collected during botanical field trips, led by Dr. Harald Förther. The specimens are deposited in the herbarium of the University Del Valle in Guatemala City, in the herbarium of the Institute of Systematic Botany of the University of Munich, in the Museum of Natural History Vienna, in the Museum of Natural History London, and the Smithsonian Institution in Washington.

Ruiz Valladares (2006) compiled information on the use of wild plants. Studies on soil, climate, forest cover, and birds were conducted during a project by University of Göttingen from 2000 to 2003 (Birner et al. 2003, Markussen 2003, Renner et al. 2006).
