Yellow River Marsh Aquatic Preserve

NEWS     |     RESOURCES     |     CALENDAR

Yellow River Marsh Aquatic Preserve is located in south-central Santa Rosa County in the western Florida Panhandle. This preserve encompasses about 11,000 acres of the Yellow River, Blackwater Bay and East Bay in the western Florida Panhandle. Located northwest of Yellow River Marsh Aquatic Preserve are the two closest population centers: the city of Milton, the county seat of Santa Rosa County and the city of Bagdad. Interstate 10 is northwest of this aquatic preserve. 

Yellow River Marsh Aquatic Preserve contains all of the sovereign submerged state-owned lands of the Yellow River, Blackwater Bay and East Bay, within the aquatic preserve boundary. Rare and imperiled natural communities can be found within or adjacent to the aquatic preserve boundaries. The publicly owned Yellow River Marsh Preserve State Park, part of the Florida’s Division of Recreation and Parks, is directly connected to this preserve at the western side of the aquatic preserve. The largest landholding adjacent to the aquatic preserve is Eglin Air Force Base. The base is responsible for managing most of its lands, especially the low-lying wetlands designated as Eglin Wildlife Management Area. 

History

This aquatic preserve was designated in 1970 for the primary purpose of preserving the biological resources in the area and maintaining these resources in an essentially natural condition. The aquatic preserve was also selected as a Gulf Ecological Management Site for its ecological significance in the Gulf of America region. 

The aquatic preserve is a vital component in the Pensacola Bay System because it has been the least impacted by development and pollution. There are more than 1,000 acres of salt and freshwater marshes and approximately 1,500 acres of forested wetlands within the aquatic preserve, which provide filtration from pollutants and serve as natural flood control. The remainder of the aquatic preserve is open water. The uplands bordering the aquatic preserve consist primarily of residential areas and public managed areas including substantial additional forested wetlands.

Eglin Air Force Base and the Northwest Florida Water Management District manage almost half of the uplands adjacent to the aquatic preserve, which help buffer impacts to water quality.

Educational Opportunities

Education and outreach efforts for Yellow River Marsh Aquatic Preserve include workshops, conferences, symposiums and research throughout the region. Public talks at school groups, garden clubs, nonprofit organizations, as well as facility tours are often given to educate the community about the program and ongoing management, education and restoration efforts. Through formal program with other locals, like Bringing Back the Bayous, Grasses to Classes, Bay Days, coastal cleanups and project tours, we can raise awareness to citizens on water quality, invasive/exotic control, habitat concerns and restoration, as well as many other topics of interest to the community.
 

Project Greenshores

Project GreenShores is a multimillion dollar habitat restoration and creation project in downtown Pensacola along the urban shoreline of Pensacola Bay. This habitat restoration effort partners DEP's Northwest Florida Aquatic Preserves with the city of Pensacola, Escambia County, the Ecosystem Restoration Support Organization, the EPA Gulf of America Program, the National Fish and Wildlife Foundation, the U.S. Fish and Wildlife Service, NOAA, Gulf Power, local agencies, businesses and volunteers in a community-based effort to restore oyster reef, salt marsh and seagrass habitat within the Pensacola Bay System. Restoring the Pensacola Bay estuary to its historic state stabilizes shorelines and provides essential habitat for wildlife propagation and conservation.

Project GreenShores was constructed in phases and consists of two adjacent sites in Pensacola Bay. Site 1 was completed in 2003 and consists of 15 acres of estuarine habitat composed of seven acres of oyster reef and eight acres of salt marsh/seagrass habitat. Site 1 has received several awards including the 2003 Coastal America Partnership Award, the 2004 EPA Gulf of Mexico Program’s Gulf Guardian Award and the Conservation Award from the Francis M. Weston Audubon Society in 2007.

In 2003, the first phase at Site 1 of Project GreenShores was completed with minimal replantings in the summer of 2004. Seven acres of constructed oyster reef consists of 14,000 tons of Kentucky limestone, 6,000 tons of recycled concrete and 40 wave attenuators. The eight-acre salt marsh incorporated 35,000 cubic yards of sand and 40,000 smooth cordgrass (Sporobulus alterniflorus plants. Project GreenShores Site 2, constructed in the summer of 2007, encompasses the area of Pensacola Bay from the western shore of Muscogee Wharf up to and including Hawkshaw Lagoon. This site consists of two submerged breakwaters of approximately 600’ x 150’x 0.5’ (below Mean Low-Water line) which were constructed using 25,000 cubic yards of recycled concrete obtained from a decommissioned airfield at NAS Pensacola. The submerged breakwaters will function to reduce fetch-driven wave energy before it reaches the intertidal marsh islands and shoreline. In time, the breakwaters will also serve as a living oyster reef as oyster larvae settle and grow on the substrate provided. Three intertidal marsh islands were constructed using 16,000 cubic yards of spoil material from a previous dredge of the Escambia River.

The islands were planted with 30,000 smooth cordgrass, grown at the DEP Nursery facility, during a substantial community volunteer effort with the help of local Boy Scout, Cub Scout and Girl Scout troops as well as numerous individuals and civic groups in September of 2007. Additional breakwater and salt marsh areas was constructed in the next few years under NRDA funding.

Ongoing Research

Continuous water quality monitoring is conducted within Yellow River Marsh Aquatic Preserve, measuring the parameters of turbidity, conductivity, salinity, temperature, dissolved oxygen and pH. Several salt marsh and oyster restoration projects have been implemented along Yellow River Marsh Aquatic Preserve. This location remains an important site for eco-restoration, monitoring and coastal resiliency projects like Living Shorelines.

Staff and partners have conducted monitoring programs of gulf sturgeon, the gulf saltmarsh snake, diamondback terrapin and several other species of concern. Since the Deepwater Horizon oil spill, focus has shifted toward water quality monitoring and sedimentation.

Summer Collaborations at Project GreenShores

Through the Pensacola and Perdido Bay Estuary Program’s Collaborative Science to Assess Restoration Success (C-STARS) project, our team has been investigating the relationship between living shorelines and seagrasses. At one site, Project GreenShores (PGS), a large-scale living shoreline site in downtown Pensacola, 2 different species of seagrasses (Halodule wrightii and Ruppia maritima) have been confirmed, but not mapped.

Message From The Manager

"A trip on the Yellow River is like going back in time. Its tall-forested banks, pristine water quality and productive fishing create a place one can go to be completely surrounded by nature. The Yellow River Preserve is one of Florida's most precious contributions it has for its future generations."
 - Ernie Rivers, River Keeper and Bream Fisherman Associate of Northwest Florida
