This past August, a new population of golden clams, Corbicula fluminea, was discovered by twelve-year-old budding conservationist, William Guthrie. The new infestation was found in Briggs Lake (Sherburne County). The discovery of golden clams in Briggs Lake is significant because it is an inland lake with no supplemental heat source. If the clams can survive our winter months, they could also spread and reproduce in additional lakes and rivers. Similar to zebra mussels, infestations of golden clams can clog water intake pipes and alter local ecosystems.

Virginia Tech.

Virginia Tech researchers who helped identify the dangerous Giant Hogweed plants in Clarke County, Virginia, want residents to stay on the lookout for the plant with toxic sap that can cause severe burns — but also stressed that the weeds are believed to have been planted intentionally decades ago and haven’t spread in the years since. Anyone who suspects they have found Giant Hogweed should take photos, check online to compare the plant to giant hogweed photos, and then contact a Virginia Cooperative Extension agent.
