Abstract
Los bosques de neblina son ecosistemas únicos que se caracterizan por estar cubiertos de neblina durante gran parte del año, lo que favorece la adaptación de diversas especies, incluyendo una notable cantidad de orquídeas. En particular, las áreas de Carpish y La Divisoria, ubicadas en los ramales de la Cordillera Azul, son especialmente ricas en biodiversidad, aunque su atractivo para la agricultura ha llevado a la fragmentación de estos ecosistemas y a la pérdida de especies. Para evaluar la diversidad biológica en estas zonas, se utilizó una metodología adaptada de Gentry, que consistió en transeptos (cinco parcelas continuas de 2 X 100 m) continuos en diferentes rangos altitudinales. Los resultados mostraron que Carpish tiene un índice de diversidad media según el Índice de Shannon y Weaver, mientras que La Divisoria presenta una diversidad media en varios rangos, pero alta en otros. En total, se registraron 73 especies, siendo Epidendrum sp y Maxillaria sp las más representativas. Estos hallazgos subrayan la importancia de promover medidas de conservación para proteger estas orquídeas.
Cloud forests are unique ecosystems characterized by being covered by fog for much of the year, which favors the adaptation of various species, including a notable number of orchids. In particular, the areas of Carpish and La Divisoria, located on the branches of the Cordillera Azul, are especially rich in biodiversity, although their attractiveness for agriculture has led to the fragmentation of these ecosystems and the loss of species. To assess biological diversity in these areas, a methodology adapted from Gentry was used, which consisted of continuous transepts (five continuous plots of 2 X 100 m) in different altitudinal ranges. The results showed that Carpish has a medium diversity index according to the Shannon and Weaver Index, while La Divisoria presents a medium diversity in several ranges, but high in others. In total, 73 species were recorded, with Epidendrum sp and Maxillaria sp being the most representative. These findings underline the importance of promoting conservation measures to protect these orchids
