The Yankee Lake Regional Wastewater Treatment Facility is a state-of-the-art system enabling the preservation of a 3,000-acre pristine wildlife area along the St. Johns River.
The facility supports a variety of Florida’s threatened and endangered species that not only utilize the Yankee Lake Property, but its adjacent County-owned natural lands, Black Bear Preserve, and Central Florida’s Wekiva Springs State Park. Situated between two Outstanding River Systems, St. Johns and the Wekiva River, the Yankee Lake Regional Wastewater Treatment Facility hosts a multitude of complex permitting, operations, and discharge hurdles.
Since 1999, key ESA staff have worked with the County to accomplish strategic permitting and compliance activities at Yankee Lake, including:
ESA staff are actively supporting this valuable avian population with the implementation of the current Scrub Jay Monitoring and Habitat Management Program (resubmitted by ESA staff to the United States Fish and Wildlife Service [FWS] in 2000). Currently, the facility supports three scrub jay families with the ability to support additional family growth from on-site, as well as off-site (Seminole State Forest and Rock Springs Run State Reserve) migrant populations.
ESA’s wildlife biologists are providing annual land management objectives that include maintaining optimal scrub and scrubby pine flatwood habitat utilizing a combination of mechanical applications (equipment to disk, grind, cut, chip, and roller chop), prescribed fire applications, and herbicides applications.
ESA also provides scrub jay monitoring services that include annual territory assessments, monthly census accounting, young of year counts, conditioning, and banding services. Additional land management tasks have included aerial interpretation of bug wood infestations and treatment options, sand pine timber harvest and pulpwood operations, and feral hog trapping.

"This is to express the support of Seminole Audubon Society to continue the contract with Environmental Science Associates (ESA) to manage the Florida Scrub Jay habitat at Yankee Lake Seminole County Northwest Water Reclamation Facility…We need continued good management to maintain a good habitat and healthy population of these special birds. It takes years to create the right nesting habitat. ESA has a proven track record with their knowledge and expertise.”
