Towards a forest health monituring stratergy

Gordon Hosking and Simon Anderson

Forest health monitoring using Viewpoint canopy assessment, with the potential to incorporate PSP-based individual tree assessment, is discussed in relation to existing knowledge about, and the value of, the plantation forest estate. The benefits of consistent, comparable, assessment data for forest health impact recognition and response, research, and asset protection are outlined. Results of a forest-level trial show the Viewpoint methodology to be sound and the cost to be less than 10 cents per hectare if coordinated with the present FOA detection survey.
