Successive photos of ponderosa pine fire effects on plot #2 in Zion National Park, Utah, USA. The plot was “scorched” (see Table 1 for explanation of fire monitoring handbook burn severity definitions) in an initial prescribed fire in 1997. The plot was “lightly burned” in a second prescribed fire that occurred in 2008. Photos were taken (a) prior to the second prescribed fire, (b) 1 month after the second fire, (c) 1 year after the second fire, and (d) 2 years after the second fire. All photos were collected at approximately the same location.
