Bivens Arm Nature Park is 57 acres of marsh and oak hammock with a wildlife sanctuary, shaded family picnic grounds, an observation pavilion and a mile-long nature trail with a 1,200 foot boardwalk. The wetlands and creeks bordered by beautiful upland mixed forests is a true natural treasure. The Park connects the southernmost Gainesville creeks to the wetlands of Paynes Prairie State Preserve. The park’s trail meanders through uplands past numerous large live oaks, while the boardwalk and main pavilion border a small marsh. Birders especially enjoy the Bivens Arm Nature Park, where wading birds, including great blue herons, little blue herons, cattle egrets, great egrets and snowy egrets can be seen. You will also see purple gallinules, common moorhens, and a variety of native turtles. You may hear barred owls or great horned owls, and in April and October you may see migratory songbirds such as hermit thrushes and American redstarts. http://www.visitgainesville.com/attractions/bivens-arm-nature-park/
