Chelsea Community Trail: Noxious and Invasive Plant Survey

Our summer student, Celeste Landon, performed a survey of noxious and invasive plants along the Chelsea Community Trail.

Celeste Landon is an environemntal science student at Simon Fraser University. As such, she is very well suited for this task. Celeste walked the entire 21 km length of this trail. She took GPS coordinates and various statistics at each incidence of a noxious plant.
