Abstract

Post-fire hillslope stabilization treatments aim to counteract the impact of fire on key soil and hillslope properties and reduce runoff-erosion risks following forest fires. We evaluated the effectiveness of wood shred mulch, long-leaved pine needle mulch, and polyacrylamide (PAM) in reducing runof...
