Dr. Lois Berg Stack works throughout the state on behalf of the University of Maine. As Cooperative Extension’s Ornamental Horticulture Specialist, she works with Maine nurseries, greenhouse and garden centers, and with home gardeners.

As a Professor of Sustainable Agriculture, she teaches a plant science course in the Department of Plant, Soil and Environmental Sciences.

Since a sabbatical leave in 2008/09, she has focused much of her research and outreach programs on topics related to invasive plants. Her other current projects address production of aronia (a native fruit that has nutraceutical properties), and assessment of native and introduced plants as pollen/nectar sources for honeybees and native bees.

Did you know?

A 2003 study in Maine found that populations of blacklegged ticks, the ticks that transmit Lyme disease, were twice as numerous in forests infested with Japanese barberry than in adjacent forests that did not have barberry.

Invasive species management could be a delectable endeavor. Come and find out!
