Résumé
Remote sensing and GIS offer useful tools for monitoring vegetation health and riparian coverage in the Monday Creek Watershed. Monitoring programs evaluate environmental plan success and measure indicators to identify change. This research demonstrates how remote sensing can be integrated into a local watershed management process and applies the technology as a tool to effectively monitor selected indicators that direct plan implementation. Data includes 2 anniversary date Landsat satellite images and digitized GIS watershed layers. A 3-phase methodology involves land use/cover mapping, normalized difference vegetation index (NDVI) analysis and change detection through cross tabulation. Forty meter stream buffers assist riparian habitat analysis. Image Classification utilized an unsupervised K-means algorithm. Analysis of regional and subwatershed conditions shows that vegetation overall remains healthy although a slight decline in regional vegetation health is visible, especially along roads and settlements. Forest cover increased, forest fragmentation declined and trouble spots in subwatersheds are identified.
