IAS Documentation Forms

Invasive Plant Patrollers start out at the Lake Stewards of Maine’s Introductory Invasive Plant Patrol training workshops. Below are instructions and field sheets used by Invasive Plant Patrol monitors.

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 the questionnaire (only the portions that apply) and sign the statement of commitment. The LSM will provide all certified patrollers with standardized field sheets and an ID card.

Our Mission

The Mission of the Lake Stewards of Maine (LSM) is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. LSM trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, LSM volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities.


LSM is a non-profit 501(c)(3) organization committed to the collection of information pertaining to lake water quality. For 40 years, trained volunteers throughout Maine have donated their time so that we may all learn more about one of Maine’s most beautiful and important resources — our lakes.
