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.

- Debris Flows (Scion publication August 2017)
There are some 1.7 million hectares of planted forests in New Zealand, and about a third of these are on erodible steepland terrain. Many of these forests were originally planted as erosion control forests and are now being harvested. There is increasing concern and media attention about the environmental effects of steepland planted forestry. These centre on the post-harvest landscape response, including the increasing occurrence of woody debris in rivers and on beaches following intense rainstorms that generate landslides,and debris flows that entrain wood and sediment.
