摘要

For 60 years, pastoralists and the government have been battling to effectively manage the single largest mesquite (Prosopis L. spp.) infestation in Australia, located on Mardie Station in the Pilbara region of Western Australia. The primary core infestation is 45,000 ha of moderate to dense hybrid mesquite. A secondary population, totalling 20,800 ha, was recently classified as a satellite core infestation, separate from the primary infestation. Management of these core infestations is particularlydifficult given the tolerance hybrid mesquite has to fire. A systematic aerial survey of the entire hybrid mesquite population has been conducted. It forms the basis for developing, implementing and evaluating the management strategy aimed at retractingmesquite populations to the core infestations, and managing the core infestations themselves. Evippe sp. #1 (Ge-lechiidae), a leaf-tying biological control agent, is having an extensive impact on mesquite growth and reproduction. Priority mesquite infestations are being treated using herbicides and machinery, with over 2500 man hours per year committed to mesquite control by the lessees of Mardie Station. The erection of strategic containment fences that build on natural barriers and prevent mesquite spread is ongoing. An integrated control trial using mechanical and fire treatments, combined with biological control agent damage, is being conducted to determine optimal strategies to best achieve a reduction in the density of moderate to dense mesquitewithin the core infestations. The integration of the above practises and the development and application of innovative techniques, combined with continued community-driven action and government support, will provide the best hope for containing this thorny menace.

SPP。）侵扰，位于西澳大利亚西澳大利亚Pilbara地区的Mardie Station。主要核心侵扰是45,000公顷的中度至致密的杂种乳房。次要人群总数为20,800公顷，最近被归类为卫星核心侵扰，与主要侵扰分开。赋予这些核心侵扰的管理是尤其造成的耐受性杂交乳房的火灾。已经进行了对整个杂种乳房人口的系统性空中调查。它构成了制定，实施和评估旨在将群体的管理战略纳入核心侵犯的管理策略，并自行管理核心侵犯的管理策略。 evippe sp。 ＃1（Ge-Lechiidae）是一种叶形捆绑生物控制剂，对乳瘤生长和繁殖具有广泛的影响。优先考虑的乳房侵染正在使用除草剂和机械进行处理，每年有超过2500名男子小时，致力于Mardie Station的承租人。建立在天然障碍上的战略遏制围栏，防止乳房传播正在进行中。正在进行使用机械和消防治疗的综合控制试验，与生物控制剂损坏相结合，以确定最佳策略，以最佳达到中度至致密髓质的密度降低。上述实践的整合和创新技术的开发和应用，结合持续的社区驱动的行动和政府支持，将为遏制这种棘手的威胁提供最佳希望。
