Study shows clear-cut logging affects flood risk in B.C.
UBC researchers said removing forest canopy and changing snowmelt patterns made 50-year floods occur every five years.
- A new University of British Columbia study indicates clear-cut logging significantly increases flood frequency and magnitude in British Columbia by causing wetter soil and earlier snowmelt.
- Clear-Cutting removes the forest canopy that blocks snow, leading to wetter soil and increased flood risks; in north-facing watersheds, floods became up to 18 times more frequent.
- Once-in-50-Years flood events now occur every five years, and rare 70-years floods now happen every nine years, illustrating forest treatments persist over 40 years and reshape watershed flood regimes.
- Senior author Dr. Younes Alila said, "This experimental evidence validates our longstanding call for better analysis methods," urging policymakers and industry to abandon clear-cutting for eco-friendly practices.
- British Columbia has lost 97 per cent of its most productive old growth forests in the past 30 to 50 years, making the findings critical to protecting downstream communities from future flood risks.
