Trends in Snag Populations in Drought-Stressed Mixed-Conifer and Ponderosa Pine Forests (1997–2007)

Figure 6

Number of snags recruited by diameter class in northern Arizona mixed-conifer and ponderosa pine forests from 1997 to 2002 and from 2002 to 2007. Recruitment occurred across all size classes and was greater in most size classes from 2002 to 2007 than from 1997 to 2002. Recruitment during the latter period especially was concentrated in the smaller size classes.
