The extent and variety of roadside environments in Australia in largely anthropogenic landscapes render them substantial remnant habitats for insect biodiversity. The importance of these areas for insect biodiversity conservation and the key threats they face are discussed, as well as the needs for their protection and conservation management. Many rural roadsides harbour significant patches of native vegetation, including rare and threatened flora now scarce elsewhere. Other values of roadside vegetation include habitat remnants, seasonal refuges, corridors and shelters for insect movements and population connectivity. Examples are given of the importance of roadsides for individual threatened insect species. Roadside environments are under substantial threat from clearing, development and unintentional degradation through a variety of activities. The diverse responsibilities of roadside management, increasingly to harmonise human safety and amenity needs with biodiversity conservation, can readily incorporate considerations of insect diversity and occurrence of notable individual species. The conservation of remnant vegetation and ecological restoration of roadside corridors are highlighted as paramount for maintaining biodiversity and connectivity under increased human activity and environmental extremes.

路边植被在澳大利亚昆虫保护中的作用

在很大程度上是人为景观的澳大利亚，路旁环境的范围和多样性使它们成为昆虫生物多样性的重要残余栖息地。讨论了这些地区对昆虫生物多样性保护的重要性及其面临的主要威胁，以及对它们的保护和保护管理的需求。许多农村路边都藏有大量原生植被，其中包括现在稀缺的受威胁植物。路边植被的其他价值包括栖息地残余物，季节性避难所，走廊和昆虫活动和人口连通性的庇护所。举例说明了路边对于单个受威胁昆虫物种的重要性。通过各种活动进行清理，开发和意外降级，使路边环境受到严重威胁。路边管理的各种职责越来越趋于使人类安全和舒适性需求与生物多样性保护相协调，可以很容易地将昆虫多样性和重要个体物种的出现纳入考虑范围。强调了在人为活动和极端环境增加的情况下维持生物多样性和连通性的最重要条件是保护剩余的植被和路旁走廊的生态恢复。
