Has Fire Suppression Increased the Amount of Carbon Stored in Western US Forests?
Year: 2008
Active 20th century fire suppression in western US forests, and a resultingincrease in stem density, is thought to account for a significant fraction of the NorthAmerican carbon sink. We compared California forest inventories from the 1930s withinventories from the 1990s to quantify changes in aboveground biomass. Stem density inmid-montane conifer forests increased by 34%, while live aboveground carbon stocksdecreased by 26%. Increased stem density reflected an increase in the number of smalltrees and a net loss of large trees. Large trees contain a disproportionate amount ofcarbon, and the…

Burned landscapes of southwestern Oregon: what's in it for Northern Spotted Owls?
Year: 2008
Northern spotted owls are known to spend time in areas burned by wildfire, but there has been little scientific investigation of how and why they use these landscapes. A trio of wildfires in southwestern Oregon during the summers of 2001 and 2002 burned through dozens of documented spotted owl territories, providing a rare opportunity to study many important aspects of how these raptors respond to wildfire in dry forest ecosystems. For this project researchers used radio telemetry and demographic surveys to investigate habitat selection, home range size, occupancy, productivity and survival…
