Article by Bob Cathcart of AgFirst Northland dated April 2017 on ‘Observations on effects of Forestry on marginal land inland of Kawakawa’.  These observations are based on land resource inventory/land use capability surveys of the Kawakawa River catchment conducted by Brian Burridge and Bob Cathcart in 1967(1) and almost 50 years later by Bob over some of the same land in 2015. In each case the surveys followed the procedures now documented in the Land Use Capability Survey Handbook, so the inventory resource inventory data that lies behind these observations is directly comparable.
