After a wildfire, the flames may fade, but the danger does not. A new study by UBC researchers reveals that burned landscapes remain vulnerable for years, with large areas still bare and at risk of invasion by fast-growing, fire-prone grasses. The research, one of the largest vegetation trajectory studies in the world, monitored landscapes two years after major wildfires in interior British Columbia (BC). While some native plants returned, recovery was slower and more fragile than expected.
