The incidence and severity of tree decline across species is now widespread in southern Western Australia. There is increasing concern about their management by agencies, landowners and the community, due to the loss of aesthetics, biodiversity and ecosystem services. This project will provide remote sensing tools to monitor peppermint health and relate declines to abiotic and biotic factors. An understanding of how water abstraction for urban development and declining rainfall predispose trees to decline, and the application of thinning regimes, fungicides and nutrient implants will provide potential tools to the wider community that can be used to manage tree health.

跨物种树木衰退的发生率和严重程度目前在西澳大利亚州南部普遍存在。由于美学、生物多样性和生态系统服务的丧失，机构、土地所有者和社区对它们的管理越来越受到关注。该项目将提供遥感工具，以监测薄荷的健康状况，并将下降与非生物和生物因素联系起来。了解城市发展的取水和降雨量的减少如何使树木容易衰退，以及间伐制度、杀菌剂和营养植物的应用将为更广泛的社区提供潜在的工具，可用于管理树木的健康。
