Madre Monte Natural Conservation Area in the Colombian Andes as Model for Preservation of Fungi in Quercus humboldtii Forests

ABSTRACT

Abstract Few conservation studies have been done with Agaricales fungi (mushrooms) of the Andes and conservation areas created in many countries have no priorities in protecting fungi. Small areas can be also very important to preserve rare and unknown fungi species, but evaluations are still needed. Applying the technique of the transects in the natural reserve of Madre Monte in Arcabuco, Boyacá Province, in the Colombian Andes (a characteristic oak forest - Quercus humboldtii - Fagaceae), the diversity and ecological data were collected and compared to the fungi already known in the country and their conservation status, to understand how fungi are protected indirectly with the creation of preservation areas. The samples were identified at the Laboratorio del Grupo de Investigación Biología para la Conservación de la Universidad Pedagogica y Tecnológica of Colombia. A total of 331 specimens and 46 species of Agaricales were collected and identified. The presence of rare species, like Lactifluus gerardii, Cortinarius violaceus and Cortinarius boyacensis, reinforces the importance of creating more small areas in the preservation of mushroom species. Only 43 species of Agaricales were reported to the province, being 19 new citations to the area, what is an indication that the diversity in the Colombian Andes is higher than suspected and that even small conservation areas have of profound impact in fungi conservation. Some of the mushrooms found are also first references to Colombia, like Panaeolus rickenii and Protostropharia dorsipora, but these were found growing in horse manure, being introduced. The impact of domestic animals and exotic trees in the mycobiota of preservation areas needs to be better evaluated.
