In this lesson from the MAPS GIS program at Lane Community College students will locate some weed and native species found in Oregon and will understand that while databases are beneficial in studying plant populations, local on-the-ground information is commonly more up-to-date and that both are required to make large scale management decisions. Students will learn that the invasion of weeds commonly follows on the heels of a disturbance (natural or otherwise) and be introduced to some of the factors that impact the success of weeds in a particular ecosystem. Students will begin to relate the data to real-life situations and how they could be used to create management plans/strategies and/or alter existing management practices. This resource includes both a teaching guide and student worksheets.
