Pile Burning Effects on Soil Water Repellency, Infiltration, and Downslope Water Chemistry in the Lake Tahoe Basin, USA
Year: 2015
Thinning of conifers followed by pile burning has become a popular treatment to reduce fuel loads in the Lake Tahoe Basin, USA. However, concern has been voiced about burning within or near riparian areas because of the potential effect on nutrient release and, ultimately, lake water quality. Our objective was to quantify the effects of pile burning on soil physical and chemical properties and resulting near-stream surface and subsurface water chemistry. Twenty-seven hand-built piles of three contrasting fuelbed types (large wood, mixed-diameter slash, small-diameter slash) were burned. Burn…

Post-fire response of riparian vegetation in a heavily browsed environment
Year: 2015
Severe wildfires infrequently occur in large heterogeneous riparian valleys. Riparian areas may affect fire behavior and the pattern of burning due to saturated soils and patchy fuels that may have high moisture content in live and dead stems. We examined the effects of a severe fire on the dominant riparian vegetation: thin-leaf alder, river birch and willow, in a broad riparian valley in Rocky Mountain National Park, CO, USA. We mapped the canopy stem mortality and basal resprouting of 4507 first year post fire and 643 second year post fire individuals that had been the dominant woody…

Fire, Fuels, and Streams: The Effects and Effectiveness of Riparian Treatments
Year: 2015
Fire is an important disturbance in riparian systems—consuming vegetation; increasing light;creating snags and debris flows; altering habitat structure; and affecting stream conditions, erosion, andhydrology. For many years, land managers have worked to keep fire out of riparian systems through theuse of buffers. A number of projects funded by the Joint Fire Science Program are shedding light onthe dynamics of fire in riparian systems. Recent research and field practice have shown that (1) ripariantreatments can be beneficial and are not as risky as previously thought; and (2) riparian…
