Non-Native and Invasive Plants
NATH2319E, 1.5 CEUs
What IS the definition of “invasive” and why should we care? Consequences of invasive plants in mid-Atlantic natural areas may be medical, ecological, environmental, or economic. This course will explore the historical and ongoing arrival of invasives, look at their cultural, legal, and ecological significance, and focus time on the identification of major species of concern in the mid-Atlantic and possible control measures. Three field trips to local parks will reinforce identification skills and emphasize current management issues.

What students say about
Natural History Field Studies:
“I am incredibly grateful for the opportunity to take classes in the NHFS program. Most environmental education is aimed at children and youth. Because nature programming wasn’t a part of my suburban childhood (and I might not have cared about it or retained it in any case) I am thrilled to be able to learn about natural history as an adult – ‘when the student is ready, the teacher appears.’ Thanks to the Audubon Naturalist Society, natural history is becoming a passion.”
- R. Gray, NHFS Student
