World Wetlands Day: Why Wetlands Matter Along the Chattahoochee

Cover image by Sebastian Hagan


Each year on World Wetlands Day (February 2), we pause to celebrate some of the hardest-working ecosystems on the planet. Wetlands may not always get the spotlight like mountaintops or waterfalls, but here at Chattahoochee River National Recreation Area (CRNRA), they quietly (and powerfully!) do it all. From filtering our water to protecting wildlife and people alike, wetlands are essential to the health of the river and the communities that surround it.


What Are Wetlands, Exactly?


Wetlands are areas where land and water meet, like marshes, swamps, floodplains, and forested wetlands that are periodically or permanently saturated with water. Along the Chattahoochee, wetlands act like nature’s kidneys, filtering pollutants and sediment before water flows downstream. They also absorb excess water during heavy rains, helping reduce flooding and erosion while keeping the river system more resilient in the face of changing weather patterns.


And then there’s wildlife! Wetlands provide critical habitat for birds, amphibians, fish, insects, and mammals, many of which depend on these areas for breeding, feeding, and shelter. If you’ve ever spotted a heron stalking the shoreline or heard frogs calling near dusk, you’ve experienced wetland magic firsthand!


Wetlands in the Park


One of the best things about wetlands at CRNRA? You don’t have to be a scientist to enjoy them!


  • Bull Sluice Lake near the Gold Branch Unit features wetland areas that support diverse plant and animal life while contributing to the health of the river. Wetlands can be viewed via a boardwalk accessed from the City of Roswell’s Roswell Riverwalk, offering an up-close look at these ecosystems without disturbing them.


  • At the Cochran Shoals Unit in Marietta, a boardwalk near the Interstate North trailhead allows visitors to walk through wetland areas and see firsthand how water, plants, and wildlife coexist in a delicate balance.

Why Wetlands Matter


At Chattahoochee National Park Conservancy (CNPC), our mission is to build community, enrich lives, and catalyze support to ensure a sustainable national park for future generations. Protecting wetlands touches every part of that mission!


Wetlands help keep the Chattahoochee River cleaner and healthier for the millions of people who rely on it for drinking water, recreation, and refuge. They enrich lives by creating spaces for education, reflection, and outdoor exploration. And when we invest in their protection through stewardship, advocacy, and community support, we’re ensuring that future generations can experience the same sense of wonder and connection we feel today.


This World Wetlands Day, we invite you to explore a boardwalk, notice the plants and wildlife around you, and remember that even the quietest landscapes play a powerful role in sustaining our park. When we protect wetlands, we protect the river and each other!

Celebrating National Park Week in Your Local National Park

Ever driven a winding, elk-lined road in Great Smoky Mountains, stopped to take in the scenery in Grand Teton, paddled in the Everglades, watched Ole Faithful erupt in Yellowstone, or even hiked in Chattahoochee River National Recreation Area (CRNRA)? If so, then you've enjoyed a national park! Every year since 1991, people across the country celebrate the over 430 parks protected by the National Park Service during National Park Week, hosted August 22-30th, 2026. From iconic landscapes like Yosemite to neighborhood escapes in CRNRA, it’s a time to recognize how parks connect, inspire, and restore communities across America, now and for future generations. It’s also a reminder that places like CRNRA rely on community support. With nearly 3 million visits each year, CRNRA is consistently ranked among the top 30 most visited national parks. As a well-loved park, it faces ongoing challenges including limited federal funding, staffing, and maintenance needs. Without the support of a national park's community, projects often go without sufficient funding to help them thrive. That's where organizations like Chattahoochee National Park Conservancy come in! Many national parks across the country have a "friends group," or a philanthropic partner, to raise awareness, rally support, and fill in the gaps in funding, volunteerism, education, wildlife habitat restoration, and more. As CRNRA's official friends group and nonprofit partner, we at CNPC work alongside the National Park Service to help fill critical gaps through community support, volunteer engagement, and projects that enhance the park experience.

Whether you're an Atlanta native or just looking for a nice nearby hike during your weekend visit, chances are you've been told to find the "Atlanta bamboo forest" or visit the "dog beach" -- both of which are located at East Palisades and part of your local national park! Just inside I-285 in Sandy Springs, towering bluffs overlook the Chattahoochee River, miles of wooded trails wind through mature forest, and a hidden bamboo grove has become one of the park's most recognizable destinations. East Palisades is one of the most visited sections of Chattahoochee River National Recreation Area (CRNRA), and for good reason! As the official nonprofit partner of CRNRA, Chattahoochee National Park Conservancy (CNPC) works alongside the National Park Service to preserve and support places like East Palisades. Memberships, donations, and volunteer support help fund trail improvements, habitat restoration, visitor programs, and projects that keep the park welcoming for millions of visitors each year.
