This program is a continuing educational opportunity designed for tree care professionals and green industry specialists.

Randy Prostak, UMass Extension Weed Specialist, in Weed Management Topics for Arborists will explore topics that tree care professionals should understand about weeds and weed management, including the impact of turf and landscape herbicides on tree health and the role of invasive plants and related regulations.

Rick Harper, UMass Extension Assistant Professor, will present Recovering Our Urban Forests: Update on Invasive Pests (& Invasive Practices). According to a recently published study performed by the US Forest Service, America’s urban forests are declining at a rate of 4 million trees per year. Since it is well-documented that urban trees provide many environmental and economic benefits, the effects associated with this decline may be numerous and extensive. Rick will highlight research pertaining to important invasive pests (insects and diseases such as Emerald Ash Borer, Asian Longhorned Beetle, Dutch Elm Disease) their integrated management, as well as invasive practices commonly found impacting the health of our urban trees.
