Environmental advocates along the Alabama coast say the state faces a narrow, possibly once-in-a-generation opportunity to permanently protect what remains of Mobile Bay’s undeveloped marshes, maritime forests and undisturbed shoreline, using a portion of the billions of dollars in fines and settlement money tied to the BP oil spill.
The argument centers on a simple reality: Alabama has never had the budget to buy up and preserve large stretches of coastal wetland on its own. The BP spill, for all the damage it caused across the Gulf, produced an unusual financial windfall for the state through legal settlements and federal penalties. Advocates argue that directing even a modest share of those funds toward land conservation could secure a lasting benefit for the region long after the spill itself fades from memory.
The marshes at the center of the debate do more than provide scenic value. They function as nurseries for much of the seafood that defines the Gulf Coast economy and dinner table, including shrimp, crabs and speckled trout. Marine biologists have long pointed to healthy marsh systems as essential to sustaining those populations in estuaries like Mobile Bay.
Some skeptics argue the marshes are already effectively protected simply because they’re too wet and unstable to build on. Coastal researchers counter that this overlooks a more pressing threat: rising sea levels. Estimates cited by coastal scientists suggest seas have already risen roughly eight inches over the last century, with projections of another two to six feet over the next hundred years. Evidence of Alabama’s historically shifting coastline is visible well inland, including fossilized marine life found near the Alabama River and remnants of an ancient cypress forest submerged roughly a dozen miles offshore in the Gulf.
Even a modest one-foot rise in sea level over the coming decades could be enough to submerge much of Alabama’s existing marshland, according to researchers who study the coast. A marsh that stops draining at low tide, they note, is a marsh on its way to dying off. That makes preserving the higher, drier ground behind today’s marshes just as important as protecting the wetlands themselves, since marsh ecosystems need somewhere to retreat as water levels climb.
Advocates warn that without intervention, continued residential and commercial development in Mobile and Baldwin counties will keep closing the gap between existing urban areas and the coastline, right up to the boundary the U.S. Army Corps of Engineers uses to distinguish protected wetlands from buildable uplands. Once that adjacent high ground is developed, they say, there will be nowhere left for retreating marsh ecosystems to go.
The push comes as officials in both counties continue deciding how to allocate their share of BP-related settlement dollars among competing priorities, from infrastructure and economic development to environmental restoration. Conservation groups argue that land acquisition and protection should rank among the top uses of that money, given how rare it is for the state to have this level of funding available for coastal preservation at all.
