To preserve forest health, the best management decision may be to do nothing

In newscasts after intense wind and ice storms, damaged trees stand out: snapped limbs, uprooted trunks, entire forests blown nearly flat.

In a storm’s wake, landowners, municipalities and state agencies are faced with important financial and environmental decisions.

A study by Harvard University researchers, supported by the National Science Foundation (NSF) and published in the journal Ecology, yields a surprising result: when it comes to the health of forests, native plants and wildlife, the best management decision may be to do nothing. (more…)

Scorched Earth: The Past, Present and Future of Human Influences on Wildfires

*A new framework for evaluating human influences on wildfires is developed*

Fires have continuously occurred on Earth for at least the last 400 million years. But since the 1970s, the frequency of wildfires has increased at least four-fold, and the total size of burn areas has increased at least six-fold in the western United States alone. Steadily rising, the U.S.’s bill for fighting wildfires now totals $1.5 billion per year.

How much of the increases in the frequency and size of fires are due to human activities? No one knows for sure. But a paper in this week’s issue of the Journal of Biogeography puts the role of fire in natural ecosystems into context and provides support for efforts to plan for future risks from wildfires.
