Abstract Where habitat loss is rapid, formerly common species may be at risk of extinction. We provide a method for using habitat mapping data and herbarium records to identify plant species that are threatened by the rapid conversion of brigalow forest, a widespread habitat type in eastern Australia that has been decimated over the last 60 years. The method weights species depending on the strength of their association with the brigalow forest habitat and their association with the Brigalow Belt region where the clearance of native vegetation has been extensive. The process identifies 56 out of a total of 1229 plant species that are at greatest potential risk. Twenty of the 56 species also occur in habitats that have not been extensively cleared. Of the remaining 36 species, 11 are closely associated with brigalow forest, which in general has been more extensively cleared than other habitats. The method revealed several species potentially imperilled by habitat loss that have not previously been identified by formal listing of threatened species. The rate of habitat loss for the target species can be clearly documented, although further survey is required to determine the potential persistence of species in habitat that has been modified by clearing and an estimate of generation length of the plant species is required in order to assess this decline against IUCN threat categories. The method has broad application in situations where there are records of species and documentation of habitat loss.

在推土机之后:在因快速清除而毁坏的栖息地中识别受威胁的物种

摘要 在栖息地丧失迅速的地方,以前常见的物种可能面临灭绝的危险。我们提供了一种方法,使用栖息地绘图数据和植物标本馆记录来识别受到快速转变的阔叶林威胁的植物物种,阔叶林是澳大利亚东部广泛存在的栖息地类型,在过去 60 年中已被大量破坏。该方法根据物种与 Brigalow 森林栖息地的关联强度以及它们与原生植被清除范围广泛的 Brigalow Belt 区域的关联对物种进行加权。该过程确定了 1229 种植物物种中潜在风险最大的 56 种。56 种物种中有 20 种也出现在尚未被广泛清除的栖息地中。其余 36 种中,11 种与阔叶林密切相关,总的来说,它比其他栖息地被更广泛地清除。该方法揭示了几种可能因栖息地丧失而受到威胁的物种,这些物种以前尚未通过正式的受威胁物种清单确定。可以清楚地记录目标物种的栖息地丧失率,但需要进一步调查以确定已被清除改变的栖息地物种的潜在持久性,并且需要估计植物物种的世代长度以评估对 IUCN 威胁类别的这种下降。该方法在有物种记录和栖息地丧失文件的情况下具有广泛的应用。该方法揭示了几种可能因栖息地丧失而受到威胁的物种,这些物种以前尚未通过正式的受威胁物种清单确定。可以清楚地记录目标物种的栖息地丧失率,但需要进一步调查以确定已被清除改变的栖息地物种的潜在持久性,并且需要估计植物物种的世代长度以评估对 IUCN 威胁类别的这种下降。该方法在有物种记录和栖息地丧失文件的情况下具有广泛的应用。该方法揭示了几种可能因栖息地丧失而受到威胁的物种,这些物种以前尚未通过正式的受威胁物种清单确定。可以清楚地记录目标物种的栖息地丧失率,但需要进一步调查以确定已被清除改变的栖息地物种的潜在持久性,并且需要估计植物物种的世代长度以评估对 IUCN 威胁类别的这种下降。该方法在有物种记录和栖息地丧失文件的情况下具有广泛的应用。尽管需要进一步调查以确定已被清除修改的栖息地物种的潜在持久性,并且需要估计植物物种的世代长度,以便根据 IUCN 威胁类别评估这种下降。该方法在有物种记录和栖息地丧失文件的情况下具有广泛的应用。尽管需要进一步调查以确定已被清除修改的栖息地物种的潜在持久性,并且需要估计植物物种的世代长度,以便根据 IUCN 威胁类别评估这种下降。该方法在有物种记录和栖息地丧失文件的情况下具有广泛的应用。
