The Preservation of UNF’s Sawmill Slough Preserve
On any given day of the week, you may find William Smith surveying Gopher Tortoise Ridge or one of the other trails within the Sawmill Slough Preserve while driving a golf cart. Though he definitely enjoys weekly visits to the Preserve, these trips are not recreational. It’s actually part of his job as assistant director of physical facilities.
Smith, who previously spent 22 years with the St. Johns County Parks and Recreation Department, manages the day-to-day operations of the Physical Facilities Landscaping and Grounds Division. He is also the curator of the Preserve. In that role, he coordinates with the Division of Forestry, North Florida Invasive Plant Society and the Florida Fish and Wildlife Conservation Commission (FWC) on key land management aspects for land preservation.

“My job is to preserve the land in its natural state,” he said. “We manage it for public access but try to keep it as natural and native friendly as possible. Our footprint in the Preserve is minimal as we try to stick to trail access only. By doing that, we are not interfering with the native flora or fauna.” When asked how visitors can assist in preserving the land, he said everyone can help by keeping it clean and only leaving footprints.

Being surrounded by nature gives UNF a visual appeal not seen at many state universities. Smith acknowledges that those who helped build the campus did a great job incorporating the natural outdoors. He believes this allows the public to experience what Northeast Florida looked like before the land was developed.

“Prescribed burns and firewise mowing are maintenance techniques that lessen the impact if there were a wildfire,” Smith said. “The goal is to cut down on the amount of fuel that is present.” A major benefit of prescribed burns is the release of nutrients back into the ground that plants and animals thrive on. While mowing does not produce nutrients like burns do, it’s equally effective in preventing wildfires and sustaining the environment.
In addition to preservation techniques happening directly in the Preserve, the landscaping crews working in the core of campus are also doing their part to protect the Preserve. Horticulturist Rhonda Gracie and the groundskeeping team use native and Florida-friendly plants to decorate the grounds making sure the ecosystem is not disturbed. They also ensure the pollinator gardens on campus are chemical-free, so harmful chemicals don’t reach the Preserve during rain runoff.
While the Preserve is an integral part of UNF’s 50-year history, it’s also an integral part of Northeast Florida’s history. As the greater Jacksonville community experiences developmental growth, the Preserve will remain protected in perpetuity for all to observe and enjoy for both leisure and educational purposes for the next 50 years and well beyond.
According to Smith, areas such as the Preserve are few in Jacksonville making it the perfect getaway to unwind and appreciate the beauty of nature right here on campus.
