Hemlock Woolly Adelgid

Staff Contact: Colin Gray

Hemlock Woolly Adelgid is an invasive aphid-like insect that infects and kills hemlock trees. It was discovered in Nova Scotia in 2017 and has spread to 5 of the province’s western counties. Hemlocks are a very important tree species in our province and a substantial player in old growth forests. Our work at MTRI focuses on sharing information on this invasive with the public, working with government to monitor its spread and assist with Nova Scotia’s management plan. We have also work with and trained private landowners to develop monitoring and treatment plans as well as being directly involved with the hemlock woolly adelgid international working group.  

Invasive Fish

Staff Contact: Thomas Sweeney

Invasive fish species, such as the Chain Pickerel and Smallmouth Bass, are a growing problem in Nova Scotia’s waterways and threaten many native species. Since 2020, MTRI has been working with the Nova Scotia Salmon Association to get to know the role that anglers play in the spread of invasive species. We have developed a list of ways that anglers can help stop the spread from reporting illegal behaviour to promoting lesser-known sustainable fishing practices. MTRI is continuing to reach out to anglers and spread awareness of just how serious a risk invasive fish pose, and what we can do to stop them.
