Marion Larson, Chief of Information and Education with the Massachusetts Division of Fisheries and Wildlife, will speak at the Arnold Arboretum on Friday, March 15, beginning at 1:30 pm, in a program co-sponsored by the Ecological Landscaping Association.  Whether trying to attract backyard wildlife, coping with the effects of wildlife damage in the managed landscape, or hoping to enhance habitat on a landscape scale, you must first understand the animals. Marion Larson will discuss the components of wildlife habitat; factors affecting wildlife populations; how to attract beneficial wildlife; and practices to consider which keep wild things wild. She will address the wildlife known to cause landscape damage and suggest strategies for preventing damage before it occurs, as well as legal options for removing or destroying wildlife when management fails. She will also share information about habitat management initiatives that the MA Division of Fisheries and Wildlife is promoting to managers and owners of larger properties.  $20 for members of the sponsoring organizations, $25 for the general public.  Register at www.arboretum.harvard.edu.
