Sonoran Desert and Mediterranean California Lichen Flora Project

9706984纳什对大索诺兰沙漠地区(亚利桑那州、南加州、下加利福尼亚州、索诺拉和锡那罗亚北部)的地衣(包括微型地衣和大型地衣)进行国际合作调查，由预算外资金92-01111供资。该项目在编写现代地衣植物群方面取得了进展，供系统学家和其他专业植物学家以及决策者使用。由于索诺兰沙漠包括大量《清洁空气法》I级地区，而且地衣是空气污染的良好指示器，预计这些植物群将对美国林务局和国家公园管理局(美国和墨西哥)的土地管理人员具有相当大的实用价值。Liason已经与墨西哥境内的机构建立了合作关系，并与世界各地60多名著名的地衣系统学家建立了合作关系。到目前为止，该项目的出版物记录了50个科学新物种的发现，并首次记录了索诺兰沙漠200多个物种的分布。到该项目完成时，该植物群将处理328属1700多种植物。

9706984 Nash A cooperative, international investigation of the lichens (both micro-and macrolichens) of the greater Sonoran Desert region (Arizona, southern California, Baja California, Sonora and Northern Sinaloa) was funded by DEB 92-01111. The project has made progress toward writing a modern lichen flora for use by systematists and other professional botanists as well as decision-makers. Because the Sonoran Desert includes a significant number of Clean Air Act Class I areas, and because lichens are excellent indicators of air pollution, it is anticipated that the flora will have considerable utility to land managers in both the U.S. Forest Service and National Park Services (both U.S. and Mexican). Liason has been established with institutions within Mexico and collaboration and with over 60 prominent lichen systematists worldwide. Publications from this project so far document the discovery of 50 species new to science, and the first records of distribution in the Sonoran Desert for over 200 more. By the completion of the project, the flora will treat over 1700 species in 328 genera.
