Reynolds Received: 8 October 2010 /Accepted: 7 January 2011 /Published online: 28 January 2011 # Springer Science+Business Media B.V. 2011 Abstract Conservation and management of the endangered Florida manatee is often centered on reducing mortality caused by watercraft collisions. Lee County, Florida, has led the state in watercraft-related mortality for eight of the last 10 years. This county is of particular concern as it contains important habitat for manatees, including extensive feeding grounds and an artificial warm-water refuge where more than 900 manatees have been recorded on a single day. Distributional aerial surveys were conducted from April 2007 through April 2009 over Lee County waters. Surveys yielded higher numbers of manatees than D. J. Semeyn 5507 S.

Grealish Florida Fish and Wildlife Conservation Commission, Division of Law Enforcement, Edwards Drive, Fort Myers, FL 33901, USA previously observed in this area. Using GIS methodology, kernel density analysis illustrated seasonal changes in distribution patterns and highlighted areas where manatees were most densely clustered. For example, during summer months, manatees were widely distributed throughout the survey area, with high-density areas associated with seagrass beds. During winter months, manatees were densely clustered at warm-water sites and over feeding grounds within close distance of these sites. These seasonal distribution patterns coincide well with speed zone designations. Counts and distributions of manatees were made available, almost immediately if necessary, to local marine law enforcement in an attempt to focus resources toward reducing manatee-watercraft collisions. Future studies should implement similar communication strategies to improve conservation efforts. Keywords Florida manatee . Aerial survey . Kernel density analysis . Lee County . Conservation . Management Introduction Over the past 40 years, aerial surveys have been used to monitor and assess number and distribution of Florida manatees, Trichechus manatus latirostris (e.g., Craig and Reynolds 2004; Wright et al. 2002). Aerial survey data are one of the primary sources of information used to create state and federal manatee sanctuaries and boat speed regulatory zones, as well as individual county manatee management plans (Laist and Shaw 2006). Listed as endangered under the Endangered Species Act of 1973, the Florida manatee continues to face anthropogenic
