Table 1 Abundance, density, and basal area of five species of snags in the Yosemite Forest Dynamics Plot. Pre-fire snags include snags inventoried at plot establishment in 2009 and 2010 and trees that died after plot establishment and before the fire in September 2013. Post-fire snags include trees that died in or up to 5 years after the fire (i.e., 2014–2018)
