Salvage logging and re-seeding a forest after a wildfire helps reduce flooding and returns water levels to normal faster, according to a new paper from a Washington State University researcher.
The paper, just published in the journal Hydrological Processes, shows that water levels are still increased up to 40 years after a fire.
“Trees work like straws, pulling water up out of the ground,” said Ryan Niemeyer, an adjunct faculty member in WSU’s Center for Sustaining Agriculture and Natural Resources (CSANR). “When you remove them, the water has to go somewhere. Flooding is common after a wildfire, as is elevated stream flow in subsequent summers. But seeing that the effect lasts for up to 40 years is a little surprising and certainly a new finding.”
Niemeyer wrote the paper with Kevin Bladon at Oregon State University and Richard Woodsmith of Woodsmith Watershed Consulting.
