Plants and Wildlife:  This preserve is representative of a tropical hardwood hammock, which is one of the most rare, unique and endangered habitats found in Collier County  and is identified in the Conservation Collier ordinance as the highest priority habitat for preservation.  Tropical hardwood hammock provides food and cover for many resident and migratory wildlife species that typically use such habitat.  Fifty-seven (57) species of birds (including the Cooper's hawk shown to the right) and one hundred and twenty-seven (127) plant species have been recorded at Otter Mound Preserve.  Other wildlife observed includes the Florida gopher tortoise, Virginia opossum, armadillo, raccoon, grey squirrel and even the occasional bobcat.

Reasons for Acquisition:  Tropical hardwood hammocks are an increasingly rare type of coastal plant community found in South Florida.  These forests are characterized by evergreen and semi-deciduous woody plant species that area also found throughout the Caribbean.  They occur on the highest coastal elevations where it rarely floods and are, as a result,  prime areas for human habitation. Development pressure has resulted in the conversion of many of these forests to urban and agricultural uses.  The preserve was primarily acquired due to the presence of tropical hardwood hammock, a priority habitat type in the Conservation Collier Program, but it also has archeological and historical significance.  It is located on the site of an ancient Calusa mound (c. 700 A.D. - 1,200 A.D.), though it is not thought to be a burial site.  Digging at the site or collection of any artifacts is not permitted.  The property was a home site for early settlers in the Caxambas Village who worked in the Marco Island clamming industry.
