Impacts of a regional multi-year insect defoliation event on seasonal runoff ratios and instantaneous streamflow characteristics

Abstract: Repeated moderate severity forest disturbances can cause short-and long-term shifts in ecosystem processes. Prior work has found that stand-replacing disturbances (e.g., clear-cutting) increases streamflow in temperate forests, but streamflow responses to repeated moderate severity disturbances are more equivocal. This study examined a moderate disturbance caused by an unexpected population irruption of the invasive insect Lymantria dispar (common name: gypsy moth) in 2015-2017. This irruption resulted in majo… Show more

“…Prior work has demonstrated advantages of a harmonic condition monitoring approach for detecting changes in forest condition in response to a recent L. dispar outbreak in southern New England including greater spatial and temporal resolution relative to aerial survey methods (Pasquarella et al., 2017, 2018a). Resulting products have been used in studies correlating spore deposition of the L. dispar fungal pathogen E. maimaiga with defoliation (Elkinton et al., 2019), determining how nitrogen dynamics interact with defoliation (Conrad‐Rooney et al., 2020), and estimating impacts of multi‐year defoliation events on streamflow and seasonal water yield (Smith‐Tripp et al., unpubl. data).…”
