After more than 15 years without a comprehensive update, the Mobile Bay National Estuary Program has released a new "State of Alabama's Estuaries and Coast" report, offering the most detailed look yet at how development, climate change and conservation efforts are reshaping coastal Alabama.

The 200-plus-page document tracks environmental trends across Mobile and Baldwin counties, with a particular focus on land-use change, water quality, habitat loss and resilience planning.

Blair Morrison, MBNEP's science and monitoring program lead, said the report represents years of coordination and data collection across agencies, universities and conservation groups.

"This has been over 15 years in the making," Morrison said. "Not only have the environmental trends changed in that time, but also the ways of conveying information have very much changed."

Unlike the 2008 report, Morrison said this version is grounded in long-term datasets that allow researchers to draw firmer conclusions.

"We wanted to make sure that we had data — that we were able to say something definitive," she said. "With this most recent report, we were actually able to come back and say a lot more definitively what some of those answers are."

Rapid growth in Baldwin County driving new environmental stress

One of the most direct findings is the scale and speed of development in Baldwin County — one of the fastest-growing counties in Alabama.

According to the report, natural landscapes have increasingly been replaced by homes, roads and commercial development, creating more impermeable surfaces that send stormwater rushing into creeks and rivers instead of being absorbed by soil and vegetation.

"We're seeing really high, really flashy rain events," Morrison said. "So really intense rain, but not necessarily more rain. That affects pollution in our waterways, the amount of litter, and sanitary sewer overflows."

This runoff carries nutrients, sediment and bacteria into waterways such as Fish River, Magnolia River and smaller eastern shore tributaries, contributing to declining water quality and habitat degradation. The report explains that these changes increase erosion, reduce oxygen levels in water and fuel algal blooms — all of which stress aquatic life.

Those pressures have already been playing out across Baldwin County. As previously reported by GCM in a 2025 story, "Rain check: How Baldwin County's growth collides with water, among rainiest in nation," which examined how rapid development combined with intense rainfall was overwhelming stormwater systems across the county.

Eastern shore rivers showing signs of strain

Fish River, Magnolia River and other brackish tributaries along Mobile Bay's eastern shore are highlighted as some of the most ecologically productive but increasingly stressed parts of the system.

According to the report, these waterways support marshes and wetlands that serve as nursery grounds for shrimp, blue crabs, flounder and other estuarine species. Historically, surrounding wetlands filtered runoff and stabilized shorelines.

However, shoreline hardening, development and rising sea levels have reduced these natural buffers. The report mentions increased erosion, habitat fragmentation and declining water quality in many of these tributaries, particularly where residential and commercial development has intensified.

Simultaneously, the report outlines growing conservation and restoration efforts aimed at slowing these losses and rebuilding natural systems along the eastern shore.

Researchers said projects in watersheds such as Fish River, Magnolia River and D'Olive Bay have focused on restoring marsh habitat, improving stream flow, reducing erosion and reestablishing native vegetation to better absorb stormwater and protect shorelines. These efforts include living shoreline installations, marsh platform rebuilding and targeted stream restoration designed to reconnect floodplains and improve water quality.

While some marsh areas along the eastern shore have seen gains from restoration, including wild rice re-establishment in D'Olive Bay, the overall trend shows continued pressure on these ecosystems.

Shoreline loss and erosion increasing flood risks

The report documents substantial loss of natural shorelines and marsh habitats across Mobile Bay, including along Baldwin County's eastern shore.

The report shows that rising sea levels, increased boat traffic, altered freshwater flows and widespread use of bulkheads and revetments have accelerated erosion. While hardened shorelines may protect individual properties, they interrupt natural sediment movement and reduce habitat that once absorbed storm energy.

Marshes and intertidal flats play a critical role in filtering pollution, providing wildlife habitat and buffering inland areas from flooding. Their decline increases vulnerability for coastal communities.

Along the Gulf Coast, towns such as Gulf Shores and Orange Beach are facing intensified beach erosion driven by storms and sea level rise. The report details repeated sand renourishment projects aimed at maintaining shorelines and protecting infrastructure.

Morrison said land use decisions today will largely determine how severe environmental problems become in the future.

"We're facing stressors on two main fronts, and that's land use change and changes in climate and long-term weather patterns," she said. "Smart planning today is going to be important in helping us prevent more extensive problems tomorrow."

Climate change intensifying storms and flooding

Climate impacts are pointed out in the report as a growing force reshaping coastal Alabama.

The report found rising temperatures are driving more intense rainfall events, extended droughts, stronger storms and accelerating sea level rise. These changes are already affecting infrastructure, water quality and habitats across Mobile and Baldwin counties.

A series of recent extreme rainfall events in Baldwin County — including historic flooding near Spanish Fort and flash floods in Fairhope and Daphne — are mentioned in the report as examples of how stormwater systems are being overwhelmed by short, intense downpours.

Sea level rise is also pushing saltwater farther inland, altering freshwater habitats and increasing shoreline retreat.

Morrison said the unpredictability of these changes complicates environmental management.

"The system is already complicated, and it's changing at various scales," she said. "That makes the management of our water and habitat resources infinitely more complicated."

Restoration projects and policy changes showing real progress

Despite growing challenges, the report emphasizes that conservation investments over the past 15 years are producing real benefits.

According to the report, public access points to Mobile Bay and its tributaries — including boat ramps, kayak launches, beaches and shoreline parks — have increased substantially since 2008.

Morrison said these access points are critical.

"If you don't know something and you don't love something, then you're not inclined to protect it," she said. "Those access points are critical for folks to really gain that sense of place here."

Additionally, the report lists dozens of shoreline and marsh restoration projects completed since 2010, many funded through federal and state resilience programs.

These projects use natural infrastructure, such as native vegetation, oyster shells, breakwaters and restored tidal creeks to stabilize shorelines, rebuild marsh platforms and reduce wave energy.

In Baldwin County, restoration work in the Magnolia River and Lower Fish River watersheds has improved stormwater flow, reduced erosion and restored degraded habitats.

In addition, active restoration and expanded aquaculture are helping reverse some losses, such as the oyster populations that have been declining significantly over the past century, the report said.

As previously reported by GCM, a new federal aquaculture bill could have major implications for Baldwin County's seafood industry, offering opportunities for growth while presenting challenges for local oyster and seafood producers.

The report also highlights large-scale conservation land acquisitions as critical for long-term ecosystem resilience.

Thousands of acres of wetlands and forested floodplain, including an approximately 8,000-acre tract in the Mobile-Tensaw River Delta, have been permanently protected through partnerships between conservation groups and the state.

These lands preserve biodiversity, improve water storage during floods and provide space for habitats to migrate inland as sea levels rise.

Opportunities for Public Engagement

Morrison said residents have multiple ways to get involved in protecting Mobile Bay and coastal Alabama. Some of the programs include oyster shell recycling, oyster gardening and volunteer water quality monitoring through Alabama Water Watch.

"These volunteer networks are incredible," Morrison said. "They provide data that show changes in oxygen, salinity and other measures in our local waterways for example — right in people's backyards."

She emphasized that citizen engagement is crucial for long-term sustainability.

"We are a non-advocacy organization, but we encourage folks to engage with their local municipalities, voice concerns to elected officials and be involved in the decisions that impact their environment."

Morrison said the report highlights the importance of proactive planning for the future.

"Environmental management and conservation is not only protecting natural habitat, but also protecting the way of life for people who live on the coast," she said. "Being more cognizant of provisioning for these environmental resources upfront — before we start planning big projects— is of utmost importance."

The State of Alabama's Estuaries and Coast report shows that coastal Alabama faces growing pressures from development, climate change and altered waterways, but restoration, conservation and smart planning are producing real progress.

"The fact that we are at the terminus of this huge watershed shows that processes are happening on big scales, intermediate scales, and just within the bay itself. That's one of the main things I want people to take away," Morrison said.

The report highlights both the challenges and the ongoing work to protect and sustain Mobile Bay and its surrounding estuaries for future generations.
