印度古吉拉特邦的吉尔狮子保护区和国家公园调查了1987年严重干旱后乔木和灌木的死亡和砍伐情况。共48公里的8个样线被用来对3个地区的植被进行采样。死亡率以保护区西部最高(22.6%),其次是国家公园(18.3%)和保护区东部(16.7%)。不同植物种类之间的死亡率差异很大,在某些情况下还存在地区之间的差异。保护区西部(13.2%)、国家公园(7.7%)和保护区东部(未观察到)之间的剥离程度也有显著差异。13种植物受到影响。在避难所西部和国家公园,不同围级的落地模式有显著差异。高植物死亡率和去皮对GIR有几个管理影响,需要仔细监测植被和有蹄类种群。
The death and debarking of trees and shrubs, following a severe drought in 1987, were investigated in Gir Lion Sanctuary and National Park, Gujarat, India. Eight line transects totalling 48 km were used to sample the vegetation in three districts. The percentage mortality was highest in Sanctuary West (22·6%) compared to National Park (18·3%) and Sanctuary East (16·7%). Mortality differed significantly among different plant species and in some cases between districts. The extent of debarking pattern also differed significantly between Sanctuary West (13·2%), National Park (7·7%) and Sanctuary East (none observed). Thirteen plant species were affected. The debarking pattern for different girth classes differed significantly in Sanctuary West and National Park. High plant mortality and debarking have several management implications for Gir and require careful monitoring of vegetation and ungulate populations.
