IAS Documentation

Below are field sheets, documentation forms and other means of data capture used by Invasive Plant Patrol monitors.  For more on how to get started as an Invasive Plant Patroller, please see the IPP training page.

Invasive Plant Patrol Monitor Certification

The goal of the IPP Certification Program is to encourage and support individual and group commitment to annual collection and submission of invasive aquatic plant screening survey data. To become a Certified Plant Patroller you must have participated in at least one Introductory IPP workshop (or equivalent training), complete a print-off version or a fillable version of the questionnaire (only the portions that apply) and sign the statement of commitment. LSM will provide all certified patrollers with standardized field sheets and an ID card.
