Natural Science & Mathematics Colloquium
The St. Mary's Arboretum Association and the Natural Science and Mathematics Colloquium series at St. Mary's College will be sponsoring a no-cost and open to all talk on exotic species and their disruptive effects on managed ecosystems. Dr. Michael J. Raupp, Professor and Extension Specialist, Ornamental Horticulture and IPM, will present his latest research and ideas about how our gardens and landscapes are altered by global change with particular reference to exotic plants and insects. Dr. Raupp's presentation will be made in Schaefer Hall 106 from 4:40 to 6:00 p.m., and is part of the long-standing and very popular Natural
Science and Mathematics Colloquium series sponsored annually at the college.
Parking is available off of Mattapany Road, via the college entrances there (look for
signage directing you).
Dr. Raupp's research in recent years has focused on elements of global change including urbanization and the importation of exotic species of insects and plants. He will discuss mechanisms underlying pest outbreaks along urbanization gradients and suggest ways to mitigate these problems. His studies of key pests including emerald ash borer, Asian longhorned beetle, brown marmorated stink bug, and lace bugs reveal how human activities contribute to pest outbreaks and what these outbreaks mean to the citizens of Maryland.
At the conclusion of the event, tree seedlings will be available to attendees, to take
home and plant in their home landscapes. The seedlings are sponsored both by the
St. Mary's Arboretum and the Chaney Foundation of Waldorf, Maryland.
