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受威胁状况

摘要背景 Restrepia 属发生在整个中美洲和南美洲受森林砍伐严重影响的山地森林地区。目标 目前的研究旨在测试使用可用在线资源确定这些兰花面临的威胁及其保护状况的可行性,以便稍后纳入 IUCN 在线数据库。方法 在线资源中搜索有关 Restrepia 物种分布的原始数据。地理空间保护评估工具 (GeoCAT) 用于生成半自动的 IUCN 红色名录评估。在谷歌地球中检查种群的位置以确定栖息地丧失。数据的比较产生了每个物种的红色名录评估。结果 观察到的 Restrepia 栖息地的损失是: 委内瑞拉 45% 的记录地点有 15 个物种,哥伦比亚 30 种占 28%,厄瓜多尔 18 种占 36%,秘鲁 8 种占 41%,哥斯达黎加 81% 和巴拿马 3 种占 32%。这种栖息地丧失恰逢这些国家的泛美公路路线。结论 即使使用最少的数据,也有可能确定 Restrepia 物种的红色名录状态。这些栖息地中的这些和其他附生兰花属面临的威胁程度相当大。
