This is a broad course covering the biology of plants that follow humans and often flourish in disturbed habitats. The aim of this course is to gain an appreciation and understanding of the natural history and ecology of Maine’s weedy flora, from the coast to fields and forests. Laboratories will focus primarily on agricultural weeds found on our farms and gardens and will include weed identification, experimental approaches for the analysis of weed-crop interactions, ecological approaches to the management of “unwanted plants” and field trips. Evaluations are based on the quality of participation in class, in-class practical exams, a plant collection, one paper, and an oral presentation.
