Forest practice guides

The Forest Practice Guides (2018) are to assist forest owners/managers and contractors to meet legislative requirements of the Resource Management Act 1991 (RMA) and in particular the National Environmental Standards for Plantation Forestry (NES-PF). They do not replace or override any statutory requirement. For various forestry operations, the guides provide options and information on a range of practices and methods to manage effects of the operations on the environment.
