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.

Multiple federal, state and local agencies have been notified of an invasive algae species discovered in Newport Bay, California. The algae, which is native to Florida and other subtropical and tropical locales, is scientifically known as Caulerpa prolifera. It can grow quickly, choking out native seaweeds and potentially harming marine life through lost habitat.
A similar species of invasive algae, Caulerpa taxifolia, was identified in California in 2000 and was successfully eradicated through a comprehensive joint local, state and federal effort in 2006. Due to the similarity between these two species, scientists believe this algae species may pose a serious threat to our local coastal ecosystems.
However, it is imperative that the public avoid contact with the plant due to its extreme ease of recolonizing from just tiny fragments. If you believe you have seen this invasive algae, please complete a Suspect Invasive Species Sighting Report: Invasive Algae - Caulerpa prolifera. Please do not collect a specimen, as this may lead to further spread.

Three Asian Hornets (Vespa mandarinia) were found in the Nanaimo area on Vancouver Island in mid-August. The identification has been confirmed by Canadian and international experts. This is the first time this insect has been found in British Columbia. Please report suspected Asian giant hornet sightings to the Invasive Species Council of British Columbia.
Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products.
USDA. Animal and Plant Health Inspection Service.
The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of backyard exhibition chickens in Los Angeles County, California. It is important to note that the presence of the disease is not a food safety concern. This is the first case of virulent Newcastle disease, previously referred to as exotic Newcastle disease, in the U.S. since 2003.
