A webinar on the impacts of droughts on urban forests is scheduled for Tuesday, July 25 at 2 pm EDT. It is being offered by the US Forest Service. You can get more information on it at http://www.climatewebinars.net/webinars/drought-urbanforests. A brief description is shown below. Preregistration is not required.
Recent droughts have caused stress and mortality in urban forests, reducing the cooling, clean air, and carbon storage provided by trees. Because human populations are growing in most U.S. cities, it will become increasingly important to maintain healthy, productive urban forests. Scientists and urban foresters are working together to quantify recent drought-related stress and find management strategies for sustainable urban landscapes.
