Symposium September 25th: “Wildfire and spotted owls: It’s a burning issue”
Study results suggest that wildfires in the western U.S. have increased in size and severity over the past several decades. This increase has raised concern over the effects of fire, particularly high-severity fire, on threatened and endangered species, including the spotted owl (Strix occidentalis). These owls typically nest within late-seral forests that have high-canopy cover, ladder fuels, and are vulnerable to high-severity, stand-replacing fire. Consequently, forest managers have developed and implemented restoration and fuels-reduction prescriptions to reduce fire risk. Controversy has arisen because of uncertainty regarding the tradeoffs between the risk to owls from habitat loss because of forest restoration activities versus the effects of wildfire. Thus, integrating protection of nesting habitat for spotted owls with forest restoration and fuels-reduction activities presents a challenge to managers. Studies are inconsistent on the effects of high-severity wildfire on spotted owls, with some suggesting that high-severity wildfire may be a serious problem for spotted owls and others suggesting that high-severity fire is not an immediate problem and can be beneficial. Confounding the issue is the interaction of effects of fire and those of salvage logging following wildfire. This symposium will provide an opportunity for presentation of current information on salvage logging effects, trends in wildfire extent and severity within the forest types occupied by spotted owls, as well as results of studies on effects of prescribed and wildfire on spotted owls. Gathering this information in one place at one time will advance our understanding on effects of fire on spotted owls and their habitat and hopefully ameliorate this conservation conflict. **To attend this symposium, you MUST register for the The Wildlife Society Conference (at least Monday September 25th)!
