Total area burned annually and recurrent burning in the Huascarán National Park and buffer zone, Peru, from 2002 to 2014 based on MODIS MCD45A1 product. The outline of the Digital Elevation Model Clip represents the BZ boundary. The interior line is the boundary of the Huascarán National Park. Few areas burned more than once during our study time period (grid map E2, E3, E5, E6, F3, and F4). Over the decade, six areas reburned in the following peak fire years: E3 (2005, 2010, and 2014), E5 top left (2003 and 2010), E5 bottom right (2005 and 2014), E6 (2003, 2005, and 2014), F3 (2005, 2010, and 2012), and F4 (2010 and 2014).
