Trends in species composition of snag populations in northern Arizona mixed-conifer (n = 53 plots) and ponderosa pine (n = 60 plots) forest. a Number of snags by species and year. b Number of newly-recruited snags by species and 5-year period ending in the indicated year. c Number of snags lost within the 5-year period ending in the indicated year, by species. Species acronyms: ABCO = white fir, PIPO = ponderosa pine, POTR = quaking aspen, PSME = Douglas-fir, and QUGA = Gambel oak. Not shown is a composite group comprised of all other species. Snags were pooled across plots within forest type
