Forest Ecosystem Monitoring CooperativeJohnCampbellprincipalInvestigatorWallyShortlecontentProviderPaulSchabergcontentProviderLindsayRustadprincipalInvestigatorUsing methods like those used to make snow at ski areas, researchers successfully created ice glaze on tree branches (remarkably similar to conditions during the Northeast’s 1998 Ice Storm) over a large northern hardwood forest area. This novel experimental tool will allow scientists to study controlled icing events of different intensity and frequency in different forest types. Researchers also held a workshop with ecosystem scientists, climatologists, physical scientists, computer modelers, social scientists, and industry experts to define the state-of- knowledge on ice storms and examine the nature and extent of these storms in the Northeast. In addition, they developed machine-learning algorithms which allow computer models to identify unique ice storm climatology in past weather systems to better predict ice storms in the future.Tree Damage AssessmentA qualitative post-treatment tree damage assessment made with leaves off on treated and untreated plots.
