我们比较了用于攀岩的悬崖和不用于攀岩的悬崖上的植物群落。对加州约书亚树国家公园18个悬崖（6个无攀爬、中等攀爬和密集攀爬）的植物多样性和群落结构进行了采样。在悬崖表面和悬崖底部取样植物。优势类群为栓皮栎、美洲栓皮栎和麻雀。鲁本斯。绝壁和悬崖底部的植物物种丰富度在没有攀登迹象的悬崖上最高，在密集利用的悬崖上最低。单株数量随着攀援利用的增加而减少。树木、灌木、草本植物和仙人掌在没有攀爬的悬崖上的相对丰度高于有攀爬的悬崖。随着攀爬利用的增加，悬崖表面的植物覆盖减少。为了尽量减少攀岩对与悬崖有关的植物群落的有害影响，适应性管理是必要的。
We compared the plant communities on cliffs used for rock climbing with cliffs not used for climbing. Eighteen cliffs in Joshua Tree National Park, California (six each with no climbing, moderate climbing, and intensive climbing) were sampled for plant diversity and community structure. Plants were sampled on cliff faces and at the base of cliffs. The dominant taxa were Quercus cornelius‐mulleri, Ericameria cuneata var. cuneata, and Bromus madritensis ssp. rubens. Plant species richness on cliff faces and at the base of cliffs was greater for cliffs with no evidence of climbing and lowest for cliffs with intensive use. Numbers of individual plants decreased with increased climbing use. Trees, shrubs, forbs, and cacti had greater relative abundances on cliffs without climbing than on cliffs with climbing. Plant cover on cliff faces decreased with increased climbing use. Adaptive management will be necessary to minimize the deleterious effects of rock climbing on plant communities associated with cliffs.
