ABSTRACT

The management of wetlands within plantation forests is important for compliance with forest and timber certification schemes and legal requirements. This review considers how setback vegetation and management has been prescribed in policy, codes and guidelines in Australia and New Zealand, focusing on setback and buffer distances, why they are prescribed, and the evidence provided on their benefit. Our findings indicate that, although prescriptive guidance is generally provided for the establishment of setbacks and buffers, there is a lack of guidance on, for example, what vegetation should be in the setback or buffer zone and how it should be managed. There is also a lack of evidence in codes of practice, guidelines and policies to support the specified prescriptive distances. Requirements and recommendations should be evidence-based and assessed for effectiveness; where this knowledge is lacking, further studies should be undertaken to provide an evidence base.

摘要

人工林内湿地的管理对于遵守森林和木材认证计划和法律要求非常重要。这篇综述考虑了澳大利亚和新西兰的政策、法规和指南中如何规定了后退植被和管理，重点关注后退和缓冲距离、为什么规定它们以及提供的关于它们的好处的证据。我们的研究结果表明，尽管通常为建立退避区和缓冲区提供了规范性指导，但缺乏指导，例如，退行区或缓冲区中应有哪些植被以及应如何管理。实践守则、指导方针和政策也缺乏支持特定规定距离的证据。要求和建议应以证据为基础并评估其有效性；在缺乏这种知识的情况下，应进行进一步研究以提供证据基础。
