NDVI Analysis: Rim Fire

After downloading Landsat 8 imagery, I performed 4 separate NDVI analyses in ENVI using bands 4 and 5. I then imported the images into ArcMap and applied a diverging color ramp to each image. Areas that are green signify healthy vegetation and red areas represent damaged vegetation.

On August 15th, 2013, which was two days before the fire, the vegetation was healthy with a mean NDVI score of 0.64. After the fire, there was a massive dip in the NDVI score because the vegetation was just damaged, which is reflective of the mean NDVI score of 0.53 on September 16th, 2013. The vegetation then started regrowing, and from August 18th, 2014 to September 27th, 2014 the NDVI scores have been increasing up to 0.60. Although the vegetation has been regrowing, it is not yet at the level that it was pre-fire, based on the years in the study period.
