As the sixth largest estuary in the continental United States, Mobile Bay is a perfect example of Alabama’s great biodiversity with a variety of plant and animal species so vast it’s hard to grasp. With a surface area of 413 square miles in Mobile and Baldwin counties, the health of Mobile Bay is of primary importance for a variety of entities, including the Mobile Bay National Estuary Program (MBNEP), which recently updated its “State of the Bay” publication.
Mobile native Jason Kudulis was recently elevated to MBNEP Director following the recent retirement of Roberta Swann, who had been director since 2009. Kudulis said the “State of the Bay” (www.mobilebaynep.com/news/the-state-of-alabamas-estuaries-and-coasts-report) is an extensive effort to provide a status report on an ecosystem that encompasses not only Mobile Bay but the Mobile-Tensaw Delta and other estuaries that flow into the bay.
“The Bay is just such a large system with so many influences and inputs,” Kudulis said. “This is our best concerted effort since 2008 to try to synthesize all of those different data points, regarding not only marine-based science but also ecosystem management, land-use changes, geography and changes in population. We had to take all those ingredients and distill it into this pot of gumbo that gives us some kind of indication of where we’re at currently in the health and vitality of Mobile Bay system. It’s a comprehensive science-based snapshot of coastal health.
“The good news is we’ve had these generational, once-in-a-lifetime investments over the past 10-plus years as a result of Deepwater Horizon (oil spill settlement).”
Kudulis said the MBNEP efforts are based on the priorities of the interactions with those who live in coastal Alabama. That input drives the program’s Comprehensive Conservation Management Plan (www.mobilebaynep.com/ccmp).
“Those (priorities) include improving access, the health of beaches and shores and what they mean to our quality of life, obviously fish and wildlife, heritage and culture, resilience and water quality,” he said. “We’ve improved our situation on a lot of those, whether through the conservation of land through Forever Wild (www.alabamaforeverwild.com/) or the investments in restoration projects to increase community resilience and restore stressed habitats. Certainly, there are a lot more access points as a result of those investments as well.
“I think the room for improvement is keeping up with our monitoring and the collection of data to better understand this complex system. We’re only seeing a snapshot over a given period, depending on who’s studying what or their expertise. There are obvious gaps, of course, when you’re dealing with everything that’s going on in the watershed from Birmingham south.”
The Mobile Bay watershed covers about 65% of Alabama and portions of Mississippi, Georgia and Tennessee. The drainage system that flows into Mobile Bay covers 43,662 square miles, the sixth largest in the U.S. The Mobile Bay ecosystem is home to 300 species of birds, 310 species of fish, 68 species of reptiles, 57 species of mammals, 40 species of amphibians and 15 species of shrimp.
“Then you have all these local watersheds from Fowl River to Magnolia River, Bayou La Batre and Mississippi Sound,” Kudulis said. “Then Mobile Bay is by itself a dynamic system. You can have a bad wind out of the east turn over the whole bay. Getting that picture is a challenge. Nothing functions in isolation, so there’s truly more work to be done to truly understand all those interactions.”
Kudulis said the ongoing research will try to determine the effects of human activity, climate variability and extreme weather.
“You can’t rely on the old data for that,” he said. “The timeline is compounding and increasing so rapidly. It’s a shift that we’re trying to get in front of.”
