Snag and deadwood biomass produced by mortality agents as a proportion of all wood originating from trees alive at plot establishment that would eventually fall or die delineated by large-diameter trees (≥60 cm DBH) and small-diameter trees (1 cm ≤ DBH < 60 cm). Of the 13,251 Mg of total tree biomass present in 2011 in 25.6 ha, 851 Mg died, 396 Mg fell to the ground, and 12,400 Mg remained alive by 2019. The horizontal brown bars at the top and bottom of the figure represent the tops of trees that broke off and fell to the ground leaving the (somewhat shortened) tree alive. The height of each bar represents the proportion of biomass that transitioned from trees directly to deadwood, or from trees to snags and then to deadwood, grouped by primary mortality agent
