Abstract
Australia has increasingly been dependent on the interest and capacity of community organisations across the country in order to accomplish environmental sustainability initiatives (e.g. urban nature protection). A comprehensive understanding of how these organisations thrive can be valuable not only for cities like Perth, where two-thirds of bushlands and wetlands have been lost in the past 150 years, but also for government strategies that seek to support these initiatives. This article draws on a systems perspective and utilises a mixed-methods approach to assess the organisational capacity–viability nexus. Findings suggest that inter-organisational ties facilitate a continuous positive feedback mechanism whereby organisations are able to acquire enough inputs and yield significant environmental outputs so that they can keep functioning until their missions are fulfilled. Based on the evidence the article discusses the potential ways to secure the future of urban environmental sustainability initiatives in Perth and beyond.
澳大利亚在完成环境可持续性项目（如城市自然保护）方面，日益依赖社区组织 的兴趣和能力。全面考察这些组织的兴盛，不仅对于珀斯这样在最近 150 年里丧 失了三分之二灌木林地和沼泽地的城市很有价值，而且对试图支持这类项目的政 府策略也有助益。本文采取系统视角和混合方法，评估组织的能力-生命力关系。 研究结果显示，组织间纽带有助于长期、积极的反馈机制，使组织得以获得足够 的投入，做出有意义的环保行动，长期保持其功能，直到完成其使命。文章通过 证据探讨了珀斯和其他地方保持环保项目持久性的方法。
