In forest ecosystems, the interplay among plant-driven processes and anthropogenic activities profoundly influences water balance dynamics. Hydraulic redistribution is one plant-driven process that can provide a large proportion of a plant's daily water. However, critical gaps exist in our knowledge of hydraulic redistribution including how forest management processes, like thinning, and site-specific factors like basal area and hillslope position, may affect it.

Seasonal changes in the magnitude and duration of streamflow can have important implications for aquatic species, drinking water supplies, and water quality. In many regions, including the Pacific Northwest (U.S.

Article Synopsis
  • Post-fire flooding and sediment loads can be dangerous in wildland-urban areas, necessitating effective mitigation strategies.
  • This study evaluated the effectiveness of straw bale check dams in five catchments affected by the 2010 Twitchell Canyon Fire in Utah, comparing treated and untreated sites.
  • Although high erosion rates were observed, the check dams did not significantly reduce annual sediment yields, with less than 50% of sediment trapped, suggesting a need for improved strategies or application in different conditions.

Mulching is an effective post-fire soil erosion mitigation treatment. Experiments with forest residue mulch have demonstrated that it increased ground cover to 70% and reduced runoff and soil loss at small spatial scales and for short post-fire periods. However, no studies have systematically assessed the joint effects of scale, time since burning, and mulching on runoff, soil loss, and organic matter loss.
