The Hawai'i-Pacific Weed Risk Assessment (HPWRA) is a free service that provides a background check on plants. Professional botanists use published information to answer 49 questions about a plant, to predict whether it is a low-risk or high-risk of becoming invasive in Hawai'i or similar Pacific islands.

These plants are known to be invasive or potentially invasive in Connecticut and are on Connecticut's list of Invasive and Potentially Invasive Plants. They are known to be present only in relatively low numbers at limited locations in Connecticut. These species should be considered for control and eradication efforts in the state when resources are available. If you find these species: Report your findings immediately to the CT Invasive Plant Coordinator at reportinvasives@uconn.edu.

This guide is intended to assist with identification of invasive plants and provide information on controlling these problem plants. Included are both non-chemical means of control as well as information on proper use of herbicides where chemical controls are needed. The choice of control measure depends on the size and nature of the infestation. If dealt with early enough, invasive plant problems can often be eliminated by non-chemical methods. However, a herbicide-based approach may be required to control an infestation that has become well established or widespread.

Watercraft are the largest vectors for spreading aquatic invasive species (AIS), such as quagga and zebra mussels into new waterways, making boat inspections a vital aspect of protecting Lake Tahoe and other nearby water bodies.
