As the Conservation Policy Director of Florida Wildlife Federation (FWF), my work is to ensure that protecting Florida’s natural ecosystems is a top priority for decision-makers. Grassy Waters Preserve is a prime example of why these efforts matter and I happen to particularly love exploring cypress swamps. Nestled within the bustling urban areas of Palm Beach Gardens, Royal Palm Beach, and West Palm Beach, this 23-square-mile wetland is not just a place for exploring. Grassy Waters is the city of West Palm Beach’s primary water supply and a critical part of the Everglades ecosystem. Spending a day here is a great way to experience the beauty of Florida’s wetlands while understanding the important role they play in all our lives. 

Walking the boardwalk trails, it’s easy to spot wading birds like limpkins in the marsh and raptors like the federally-endangered snail kite in the sky, both hunting for abundant apple snails. Banded water snakes occasionally rest on the buttressed trunks of cypress trees, and alligators cruise through the basin marsh. These wetlands aren’t just beautiful homes for wildlifethey’re essential for filtering rainwater, replenishing aquifers, and providing flood protection to the surrounding areas. 

Grassy Waters serves as West Palm Beach’s main drinking water source, which makes its protection a top priority. A few years ago, a toxic algae bloom raised alarms about water safety in the area. Blue-green algae, which can release harmful toxins, was detected in the preserve, highlighting the risks posed by nutrient pollution and rising temperatures. While the city managed the situation, it was a clear reminder of how vulnerable our water sources are and the importance of FWF’S work alongside partners to petition the Environmental Protection Agency for the establishment of cyanotoxin standards.  

The Preserve is also a key link in the greater Everglades ecosystem, supporting countless species that depend on these wetlands. From otters and bobcats to anhinga and osprey, the biodiversity here reflects the health of the ecosystem as a whole. When we protect places like Grassy Waters, we’re not just preserving a local park—we’re safeguarding an entire network of interconnected habitats that stretch across Florida. 

Spending time at Grassy Waters makes it clear why conservation is so important. This wetland provides clean water, protects wildlife, and offers a peaceful space for people to connect with nature. It also highlights the growing threats from pollution, climate change, and overdevelopment. As we move forward, protecting places like this will require a dedication to strong policies and community support. I encourage everyone to visit, appreciate what’s at stake, and join efforts to ensure Florida’s wetlands and wild spaces remain protected for future generations.
