Impact of postfire logging on soil bacterial and fungal communities on biogeochemistry in a mixed-conifer forest in central Oregon
Year: 2010
Aims Postfire logging recoups the economic value of timber killed by wildfire, but whether such forest management activity supports or impedes forest recovery in stands differing in structure from historic conditions remains unclear. The aim of this study was to determine the impact of mechanical logging after wildfire on soil bacterial and fungal communities andother measures influencing soil productivity.Methods We compared soil bacterial and fungal communities and biogeochemical responses of 1) soils compacted, and 2) soils compacted and then subsoiled, to 3) soils receiving no mechanical…

Postfire woodpecker foraging in salvage-logged and unlogged forests of the Sierra Nevada
Year: 2008
In forests, high-severity burn patches—whereinmost or all of the trees are killed by fire—often occur within amosaic of low- and moderate-severity effects. Although therehave been several studies of postfire salvage-logging effects onbird species, there have been few studies of effects on bird speciesassociated with high-severity patches in forests that haveotherwise burned at lower severities. From 2004 to 2006, we investigatedthe foraging presence or absence of three woodpeckerspecies, the Black-backed (Picoides arcticus), Hairy (P. villosus),and White-headed (P. albolarvatus) Woodpeckers,…
