POINT INTERCEPT (PI) AQUATIC PLANT SURVEYS
Point Intercept (PI) surveys capture current baseline data about aquatic plant communities within a waterbody. This data can be used to show stability or changes to those plant communities over time.
PI surveys are an integral part of Aquatic Plant Management (APM) Plans for a waterbody and thus a key component to Lake Management Plans (LMP). PI surveys need to be updated every five years for management plans to be current.
Another important use for PI surveys is to monitor native plant communities before and after herbicidal treatments to invasives species such as Eurasian watermilfoil. Some lakes will use PI surveys to monitor the health of the native plants for several years after a treatment.
