Abstract

ABSTRACT Background The genus Restrepia occurs throughout Central and South America in areas of montane forest heavily affected by deforestation. Aims The current study was designed to test the feasibility of using available online resources to establish the threats facing these orchids and their conservation status for later inclusion in the IUCN online database. Methods Online resources were searched for primary data on the distribution of species of Restrepia. The Geospatial Conservation Assessment Tool (GeoCAT) was used to produce semi-automated IUCN Red List assessments. Locations of populations were examined in Google Earth to establish habitat loss. A comparison of the data produced a Red List assessment for each species. Results The observed losses of Restrepia habitat were: Venezuela 45% of recorded locations for 15 species, Colombia 28% for 30 species, Ecuador 36% for 18 species, Peru 41% for eight species, Costa Rica 81% and Panama 32% for three species. This habitat loss coincided with the route of the Pan-American Highway in these countries. Conclusions It was possible to establish the Red List Status of Restrepia species even with minimal data. The degree of threat facing these and other epiphytic orchid genera in these habitats was shown to be considerable.

对Restrepia（兰科）保护状况的评估揭示了该属的濒危状况

Restrepia属分布于中美洲和南美洲受森林砍伐严重影响的山地森林地区。本研究旨在验证利用现有的在线资源来确定这些兰花面临的威胁及其保护状况的可行性，以便日后将其纳入IUCN在线数据库。方法在网上检索有关雷氏菌属分布的原始资料。利用地理空间保护评估工具(GeoCAT)进行半自动化的IUCN红色名录评估。在b谷歌地球上检查了种群的位置，以确定栖息地的丧失。对数据的比较产生了对每个物种的红色名录评估。结果委内瑞拉15种、哥伦比亚30种、厄瓜多尔18种、秘鲁8种、哥斯达黎加81%、巴拿马3种、厄瓜多尔18种、秘鲁41%、哥斯达黎加81%、巴拿马32%。这种栖息地的丧失与泛美公路在这些国家的路线相吻合。结论即使资料很少，也可以建立雷氏蚤红色名录。在这些生境中，这些和其他附生兰属面临的威胁程度相当大。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
