亚利桑那州雷蒙山上的志愿者正通过堆积岩石建造小型水坝结构来防止土壤流失，这项工作是对2020年特大山火生态恢复的关键举措。1
大角火灾始于2020年6月5日因闪电引发，持续7周至7月23日被扑灭，烧毁近12万英亩林地。1火灾后，雷蒙山面临严重的洪水和泥石流风险。1为应对这一威胁，Sky Island Alliance与志愿者自2023年以来已在该地区建造超过500个侵蚀控制结构。1这些低技术恢复设施通过减缓水流、捕捉土壤和碎片，有效防止山体进一步侵蚀。1
Sky Island Alliance是一个有35年历史的非营利组织，专注于保护和恢复亚利桑那州、西南新墨西哥州及墨西哥北部索诺拉地区的生物多样性。1雷蒙山因比图森市低约20摄氏度而成为夏季避暑胜地。1
Volunteers working on Mount Lemmon in Arizona are constructing low-tech erosion control structures to mitigate damage from wildfire and prevent soil loss on the mountainside.1 The effort involves stacking rocks into small dam-like formations that slow water flow, capture soil, and trap debris.1 This restoration work is part of a broader recovery initiative following the Bighorn Fire, which ignited on June 5, 2020, when lightning struck the area and burned nearly 120,000 acres before being controlled on July 23.1
Since 2023, Sky Island Alliance and its volunteers have constructed more than 500 erosion control structures near Mount Lemmon.1 Sky Island Alliance, a nonprofit organization with 35 years of history, focuses on protecting and restoring biodiversity across Arizona, southwestern New Mexico, and the Sonora region of northern Mexico.1 The post-fire landscape presents urgent challenges; Mount Lemmon, which sits approximately 20 degrees cooler than nearby Tucson and serves as a summer refuge, now faces heightened risks of flooding and debris flows.1
