Crosby Sanctuary Tree Survey: Identification of Native and Nonnative Tree Species in Orange Park Florida

Student: Lexi Lindsley
Community Partner: Duval Audubon Society
In partnership with the Duval Audubon Society, over 280 trees were identified and virtually tagged within their diverse 510-acre property known as the Crosby Sanctuary. A basic survey was performed that included plants >25 feet in height and within 25 inches from the ~1.5 miles of trails winding through the entire sanctuary. In addition, the locations and names of the identified plant species were input onto an online map of the Crosby Sanctuary. The updated map also contains the location of the pre-existing trails, rivers, and other features within the property. Due to the map being created via Google Maps software, it is currently available to the public via website link. Major tree species that were identified within the survey include Laurel Oak, Water Oak, Slash Pine, Bald Cypress, Pond Cypress, Sweetgum, and Red Maple. All of the plant species identified were trees, as a result of the previously established criteria for the survey (>25ft height). As a result, less than 1% of the trees sampled were nonnative to Florida. This low nonnative percentage may reflect the failure to include various vine, shrub, and foliage species. However, signs of invasive species were prevalent in the form of Red Ambrosia Beetle caused Laurel Wilt Disease.
