摘要
We used the Landsat Thematic Mapper (TM) enhanced wetness difference index (EWDI) to detect forest changes in the Fundy Model Forest, a large, multi-jurisdictional forest management unit in southeastern New Brunswick. The average annual change on the landscape was approximately 3068 ha over a 15 year interval (1984-1999). The estimate of total change (almost 50 000 ha) as a percentage of the total Fundy Model Forest available productive forest land (approximately 240 000 ha) translates into a rate of change of approximately 1.3% annually.
