Invasive Species Management from Local and National Perspectives

With Karen Riggert with Assabet Pulling Together and Katrina Scheiner who is "Doing Battle with the Yellow Crazy Ant in the Remote Pacific."

Over 700 nautical miles southwest of Honolulu, HI, Johnston Atoll NWR is one of the most remote atolls on the planet. Sadly even such remote islands aren't immune to invasive species and in January 2010, an infestation of yellow crazy ants (Anoplolepis gracilipes) was found on Johnston Island. Not much is known about yellow crazy ants (YCA), but they are highly mobile and easily invade new areas. Once established they can wreak havoc on the populations of nesting seabirds, who suffer skin irritation, blindness, and loss of reproductive success as a result of the ants’ invasion. Johnston provides some of the only non-rat-infested nesting habitat for seabirds in about 750,000 square miles of ocean and so by August of 2010 a plan had been devised and the first Crazy Ant Strike Team (CAST) was assembled and deployed to the island. Since then, crews of five have been studying the ants and have managed to reduce the population by 99%, but still continue to work towards eradicating the pest. Katrina Scheiner is the CAST crew leader for 2014 and 2015.

Following Katrina's presentation, Karen Riggert will talk about the invasive species management at the refuge during the first year of the Assabet Pulling Together (APT). Thanks to hardworking volunteers APT is making way for natives on the refuge by removing invasive plants.

Friends Monthly Speaker Series with Eileen McGourty and Marianne Piché talking about New England Cottontails of Massachusetts

Join U.S. Fish and Wildlife Service Wildlife Biologist Eileen McGourty and MA Division of Fisheries & Wildlife Habitat Biologist Marianne Piché for a presentation about the Conservation Strategy for the New England Cottontail Rabbit.

As this species is a candidate for protection under the Endangered Species Act, the U.S. Fish and Wildlife Service is partnering with the Massachusetts Division of Fisheries & Wildlife to implement conservation efforts. This talk will include details about Eileen’s work within the Eastern Massachusetts National Wildlife Refuge Complex related to rabbit surveys, and a trapping and tracking project in Mashpee where both Eastern and New England cottontails were tracked in order to determine habitats being used by the rabbits, and to determine home range size. Marianne will also discuss habitat management techniques taking place on federal, state, tribal, and private land in areas where New England Cottontail occur.

The Friends of the Assabet River NWR holds its monthly speaker series on the fourth Wednesday of each month at the US Fish and Wildlife Services' Eastern Mass. Visitor Center, 680 Hudson Road, Sudbury MA 01776 (Google Map). Talks are free and open to the public.
