Learn to Identify Invasive Plants

Invasive plants pose a serious threat to our native habitats and wildlife. One of the best things you can do to help stop the spread of invasive plants is to learn how to tell them apart from other plants. Identifying the invasive species present is the first step in planning an invasive control project or strategy, and control options will vary based on the invasive plant or plants that you are looking to manage. Learning to identify common invasive plants will better prepare you for planning and prioritizing control. 

Early detection & rapid response helps to prevent or slow new invasive species coming into an area. It’s much easier to remove a few plants to stop a species from becoming established than to tackle a species that fully inhabits an area. This is true for invasive plants that are new to your property or new to your region. Learning to identify invasive plants that are nearby but not yet in your area can help prepare you to tackle a potential infestation quickly and efficiently.
