Con el interés de promover su conservación, este trabajo documenta la diversidad de su flora orquideológica e identifica especies vulnerables a la extinción utilizando como criterio la distribución geográfica latitudinal y por elevación. El área de estudio comprendió 742 ha localizadas en las partes altas de los cerros (1600–1850 m) las cuales reciben la mayor influencia de la nubosidad. Se documentaron 136 especies en 52 géneros, aumentando en 74%  la diversidad de orquídeas con respecto al listado más reciente para la zona. Los géneros Epidendrum (22 spp.) y Stelis (14 spp.) fueron los más diversos, pero la mayoría de ellos (62%) estuvieron representados por una sola especie. El hábito epífito fue dominante (91%). Se identificaron 30 especies como vulnerables a extinción debido a su distribución restringida, ya sean endémicas nacionales o de bosques montanos altos (sobre 1500 m). Sumando las especies amenazadas por extracción ilegal y aquellas especies raras no recolectadas en los últimos 80 años la cantidad de especies vulnerables aumenta a 40 especies (29% del total). Los Cerros de La Carpintera son un reservorio importante para la conservación in-situ de orquídeas a nivel nacional. Utilizando las orquídeas como modelo, estudios demográficos y reproductivos a mediano plazo podrían brindar indicios del efecto del cambio climático sobre las plantas epífitas de los bosques montanos nubosos. \u0000Palabras clave: Cerros de La Carpintera, conservación, distribución geográfica, endemismo, epífitas, Orchidaceae","PeriodicalId":18023,"journal":{"name":"Lankesteriana","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45132286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
