ABSTRACT
Stand-replacing disturbances due to severe weather have historically been rare in the Northern Forest; however, the frequency of extreme storms in the region is projected to increase. A windstorm in 2010 severely damaged trees in Chittenden County, Vermont. Forest managers salvage harvested storm-impacted stands, removing trees blown over or otherwise injured. This proposed research will quantify cumulative impacts of windstorm and salvage harvest on ecosystem services in the Northern Forest. Across a range of disturbance intensities I will quantify regeneration and factors that influence tree recruitment including coarse woody debris abundance, remnant canopy trees, and interactions between Rubus and native tree species. I will also quantify disturbance impacts to species richness and diversity of herbaceous plants and ground-dwelling invertebrates along a gradient of disturbance intensity. This biodiversity data will serve as a test of the Intermediate Disturbance Hypothesis, which predicts that highest biodiversity results from moderate intensity or frequency ecosystem disruptions. I expect to find forest recovery rates highest at sites subjected to wind disturbance and moderately intense salvage harvest. Rubus species likely have allelopathic and shading impacts on native hardwood species, thus limiting their recruitment in post-disturbance vegetation. I expect biodiversity to be highest in sites where salvage harvest was moderate. I will share results and conclusions via peer-reviewed publications, professional and academic conference presentations, press releases, and public workshops for Vermont forestland managers.
