Alexander R. Brash has been named president of the Connecticut Audubon Society, which has its headquarters here on Burr Street. He will take over the post Sept. 9, replacing Robert Martinez, who retired in August after a decade as president of the organization.

Brash, a Greenwich resident, was senior director for the northeast region of the National Parks Conservation Association, a non-profit organization that works to protect and support America's national parks. During his tenure there, he opened the Northeast Regional office, developed many programs, and helped raise more than $40 million for the organization. Other previous positions include chief ranger and head of the Natural Resources Group for the New York City Department of Parks and Recreation. Prior to his work for New York City, he worked for the World Wildlife Fund and the Nature Conservancy. He has also edited and written a number of books and articles.

"The board was unanimously enthusiastic about Alex," Ralph T. Wood, chairman of Connecticut Audubon Society's board of directors, said in a statement. "We are counting on him to lead and guide our organization to even more achievements in our conservation, education, advocacy and EcoTravel programs, and to help our centers and sanctuaries retain their status and popularity among our members and visitors."

With state headquarters in Fairfield, CAS operates five centers that, in addition to Fairfield, include Pomfret, Glastonbury, Milford Point and Birdcraft Museum, also in Fairfield. The group also an EcoTravel program based in Essex, and is overseeing a coastal habitat restoration project at Stratford Point. The organization owns 19 sanctuaries, encompassing 2,600 acres. Brash will oversee a staff of 30.

Brash will lead the organization as it expands its three-pronged approach to conserving Connecticut's birds and their habitats, focusing on education, conservation and advocacy, according to Audubon's announcement of the appointment.

"I am honored to be asked to lead Connecticut Audubon Society, an organization long known for its sanctuaries and its great work in environmental education," Brash said in the statement. "I particularly look forward to working with its members, friends and its regional Boards to advance a progressive environmental agenda for the benefit of the state and its people."

Brash has a bachelor of science degree from Connecticut College with honors in zoology, and a master's degree from Yale University.
