Programs and Offerings
Join invasive species managers, industry professionals, private and commercial applicators, non-governmental organizations, educators and concerned citizens by becoming a member of CWMA.
Membership
CWMA is championing the industry by ensuring that rules and regulations at the state level help and not hurt your ability to perform your job. CWMA is part of coalitions that advocate for the industry by reviewing proposed legislation, taking positions and developing grassroots action.
Legislative and Policy Action
Noxious weeds are plants that are not native to our area. Most have come from Europe or Asia either accidentally or as ornamentals that have escaped. These plants have an advantage because the insects, diseases, and animals that normally controls them are not found here. Because these plants have developed specialized mechanisms to survive, they spread at an alarming rate.
Noxious Weeds
CWMA brings you the latest weed management techniques and effective practices with its various training opportunities both in person and online. CWMA trainings are designed for qualified supervisors, certified operators, and private applicators seeking CE credit to renew their license; seasonal or new hires looking to gain knowledge; and any professional or member of the public that is interested in learning about these topics.
