Hydraulic Redistribution by Native Sahelian Shrubs: Bioirrigation to Resist In-Season Drought

September 18, 2018 / publication

Hydraulic redistribution (HR) by woody vegetation has been proposed as a potential water source for crops in intercropped systems. The native woody shrub,

Press Releases: Low-severity wildfires impact soils more than previously believed

September 14, 2018 / news

Low-severity wildland fires and prescribed burns have long been presumed by scientists and resource managers to be harmless to soils, but this may not be the case, new research shows. According to two new studies, low-severity burns cause damage to soil structure and organic matter in ways that are not immediately apparent after a fire.
