Table 1 Evolution of surface fuel immediately following fire (2014) and in the 5 years following in the 25.6-ha Yosemite Forest Dynamics Plot. The Rim Fire of 2013 directly consumed 12% of trees ≤ 10 cm DBH, but very few trees ≥ 10 cm DBH (0.5%). Most fire-killed trees and snags that persisted through the fire fell in subsequent years. For yearly progression of trees, snags, deadwood, recruitment, mortality, and snagfall, see Table S1

  1. Less than 25% of original bole remaining in 2014
  2. Trees and snags that fell during or after fire with the remaining stump < 1.37 m tall
  3. *Explicitly mapped pieces of wood ≥ 10 cm diameter and ≥ 1 m long and non-mapped pieces of wood from trees 1 ≤ DBH ≤ 10 cm, with those smaller trees assumed to have fallen as one piece (see the “Methods” section)
