The Earth's climate is changing.
A community with dense overhead tree canopy may benefit from reduced stormwater runoff volume through interception, transpiration, and infiltration but may also suffer from excess nutrients leached to nearby receiving waters from leaf litter. Bill Selbi
The goal of the webinar is to provide an overview of soil management for urban trees. Specific emphasis will be given to soil assessment.
An ever-growing, international body of research points to many human health and wellness benefits that result from nearby nature experiences. But what about trees?
Nate Siegert, Ph.D., USDA Forest Service, discusses the latest information pertaining to the Emerald Ash Borer (EAB) and its continued spread across the urban forests of the U.S. and Canada.
Oak decline is a slow-acting disease complex that involves the interaction of biotic and abiotic factors such as climate, site quality and advancing tree age.
Iconic tree species include those native trees that once dominated the typical American city landscape. The American elm and chestnut are the first two that come to mind, and now ash trees are similarly under significant threat of loss.
Tree defects such as co-dominant leaders, girding roots and buried trunk flares, present at time of planting, cause failures and decline long after the warrantee period has expired. Landscape architects may go to nurseries to tag trees; but often inspe
Tree diseases are controlled primarily by spray applications of fungicides.
Urban stormwater is a major contributor to surface water degradation in the United States, prompting cities to invest in green infrastructure - methods that naturally capture, store, and slowly release runoff, such as urban trees.
