One year after a wildfire burns in a forest, the U.S. Forest Service assesses the damage.
What the agency finds at this one-year mark informs its post-fire restoration efforts, including how many trees foresters are required to plant to replace ones that died due to the fire. But according to a growing body of research, one year just isn’t enough time to determine how many trees have died following a wildfire.
Two recent studies, created independently of each other, that examined the effects of wildfires in Oregon, Washington as well as other parts of the West, found that trees scorched by fire can continue to die for as long as five years after a wildfire.
While there is as yet no scientific consensus about what these findings mean for post-fire restoration, the implication, according to some scientists, is that the ecological damage caused by wildfires has been underestimated and restoration efforts are not keeping up.
The amount of climate-warming carbon lost to the atmosphere when trees die likely has also been underestimated, according to one of the two studies, implying that the current carbon-absorbing power of some forests has been overestimated.
