The @USGeologicalSurvey National Land Cover Database (NLCD) informs the study of land change from natural or man-made disasters. Note the huge swath of shrubland that gave way to grass between 2011 and 2013 after large wildfires burned through Nevada's northern border. By 2019, small patches of shrubland begin to reappear.
