Abstract:
SPOT Satelllite imagery was used to assess the effect of a single storm in terms of the increase in bareground by comparing 1986 SPOT XS and 1988 SPOT PAN imagery for the major forests of Mangatu, Tokomaru and Ruatoria of the Gisborne-East Coast, New Zealand. DRAGON software was used on a personal computer to enhance, register and classify eleven selected sub-images, each of which covered an area planted with Pinus radiata in one of four different age classes. Classification results showed that younger age classes (less than eight years old) have less effect in preventing erosion than plantations more than eight years old. The older stands had considerable effect in controlling erosion in the forests of Mangatu, Tokomaru and Ruatoria.
