Weeks Bay National Estuarine Research Reserve


Weeks Bay National Estuarine Research Reserve is located on the eastern shore of Mobile Bay near the town of Fairhope, Baldwin County. It comprises 6,525 acres of water and tidal and forested wetlands and is managed by the Alabama Department of Conservation and Natural Resources (ADCNR) and the National Oceanic and Atmospheric Administration (NOAA), with support from the nonprofit Weeks Bay Foundation and individual volunteers. The reserve was established in 1986 to preserve a representative portion of Mobile Bay's estuarine habitat for research and educational programming.

Weeks Bay Reserve is the only preserve in Alabama within the National Estuarine Research Reserve System (NERRS), a nationwide network of 27 coastal reserves managed for long-term research and education and interpretative programs on estuarine habitats. The goal of NERRS is to establish and manage, through cooperative arrangements between federal and state agencies, a nationwide system of reserves representing the different coastal regions and estuarine ecosystems that exist in the United States.

The Weeks Bay National Estuarine Research Reserve in Weeks Bay National Estuarine Research ReserveWeeks Bay is a small tidal inlet connected to the much larger Mobile Bay. It was selected for the NERRS program because the waterway and surrounding land is representative of the greater Mobile Bay ecological system and the Mississippi delta environment and habitat. Recent development in the area was an impetus for preserving the area. Weeks Bay is fed by the Fish River and the Magnolia River, which together drain 198 square miles of watershed. Weeks Bay is shallow, with an average depth of less than five feet, and is bordered by a variety of habitats, including freshwater and saltwater marshes, tupelo and cypress swamps, upland and bottomland forests, and unique bog habitats.

The establishment of the reserve dates to the late 1970's, when the Nature Conservancy (TNC), a national conservation group, purchased 615 acres of coastal land with the intent of donating it to the federal government to be included in Bon Secour National Wildlife Refuge. After the federal government decided not to include the land as part of the refuge, in 1980 TNC agreed to donate the land to the state of Alabama if it was designated as an estuarine reserve. Over the next five years, the Alabama Department of Conservation and Natural Resources and the National Oceanic and Atmospheric Administration worked to establish the reserve, culminating in the final approval of the Management Plan for the sanctuary in November 1985. During this five-year development period, in 1981 and 1982, the preserve's boundaries were expanded when the Alabama state government purchased additional acreage and TNC donated more land. In 1986, Weeks Bay was officially designated as the nation's 16th National Estuarine Sanctuary, with a total of 3,028 acres. With the inclusion of contiguous submerged lands and waters and some small additional land acquisitions, the current acreage has more than doubled.

In 1990, private citizens and representatives from state and local agencies and educational institutions established the non-profit Weeks Bay Foundation to serve as the fund-raising arm of the preserve. The foundation seeks funding through donations, grants, and membership fees, assists in property acquisitions, and conducts special programs. The foundation staff is governed by an elected Board of Directors. The foundation currently has more than 550 members who assist the staff in education, research, and environmental protection functions, including such projects as water quality monitoring and educational outreach programs. The preserve features the 4,000-square-foot Weeks Bay Reserve Interpretive Center, constructed in 1994 to house informational displays and live animal exhibits and offer educational programs for school groups and other organizations. From the center, visitors can traverse 5,000 feet of boardwalk and more than two miles of nature trails that take them through a native pitcher plant bog, a butterfly and hummingbird garden, archaeological displays, and estuarine habitats. A research facility with a 50-seat auditorium completes the facilities infrastructure. The reserve also participates in a Web-based distance-learning project in cooperation with Faulkner State Community College and professional development programs for teachers.

The Weeks Bay ecosystem provides habitat for as many as 19 threatened and endangered species, including the bald eagle, Alabama shovelnose sturgeon, Alabama red-bellied turtle, alligator snapping turtle, Gulf salt marsh snake, and eastern indigo snake. Additionally, Weeks Bay shelters the American alligator, Atlantic bottlenose dolphin, and numerous freshwater and marine fish and invertebrate species, including shrimp, oysters, and the blue crab. It is also a sheltered haven for resident and migratory waterfowl and shorebirds, including brown pelicans and osprey. The forested acreage of the reserve provides habitat for black bear, deer and other mammals as well as critically important stopover points for a large number of migratory songbirds. Nearly 350 species of birds are found in the coastal wetlands.

The threats to Weeks Bay Reserve are those common to all of the Gulf Coast and include water pollution, habitat loss caused by soil sedimentation from construction, and development on buffer wetlands that destroys habitat. The reserve plans to purchase lands that become available for sale to mitigate these issues. The most significant and unexpected threat to the bay to date occurred in April 2010, when millions of gallons of oil gushed into the Gulf of Mexico after an underwater explosion on an oil rig owned by Deepwater Horizon, under contract with British Petroleum (BP). The long-term effects of the Gulf oil disaster are still unknown, but during the spill itself, the nearby town of Magnolia Springs took the initiative and purchased an oil-absorbent boom after the absence of a timely response by BP or the federal government. The boom was deployed across the mouth of the bay with the assistance of local fire departments. The barrier and the fact that very little of the oil spread into the immediate Weeks Bay area as a result of its geographic location apparently spared it from major damage. Ongoing sampling and analysis of water and soils in the area is ongoing.
