SANCHEZ RECUAY, María  e  CALDERON RODRIGUEZ, Abelardo. Preliminary assessment of orchids in the National Park Cutervo, Cajamarca - Peru. Ecol. apl. [online]. 2010, vol.9, n.1, pp.1-7. ISSN 1726-2216.

In the department of Cajamarca, the so-called "cloud forests of the tropical rainforest" (characterized by their great variety of orchids, floristic complexity and endemism centers) are home to the "Cordillera de los Tarros" Forests, inside Cutervo National Park. This first National Park created in 1961 in Peru, is currently experiencing the irrational exploitation and destruction of its forests, as a consequence of logging activities and the expansion of agricultural and livestock frontiers. The potentials and risks in these forests, as well as scarce knowledge on the Orchidaceae family, prompted this preliminary study on richness and distribution of orchids using square sampling plots and transects, during the months of February and March, 2004. Despite the difficult identification of the species that were found, due to the fact that it was not the characteristic flowering time for the orchids, a total of 88 morphospecies were found, 63.6% were identified and distributed into 16 genera, of which Pleurothalis, Epidendrum, Maxillaria and Stelis proved to be the most diverse and frequent in the study area.
