In Tampa, Florida, the Southwest Florida Water Management District has been diligently overseeing the condition of seagrasses in the Tampa Bay region for nearly four decades. These vital underwater plants serve as a reliable indicator of water quality, forming a habitat for up to 75% of essential fish species. Seagrasses not only help to mitigate storm surges but also stabilize sediments, making them a cornerstone of the estuarine ecosystems along Florida’s west coast.
The district conducts comprehensive seagrass surveys every few years, utilizing both aerial and underwater methods. The current in-water assessments are underway, with results anticipated in the spring of 2027. These studies focus on measuring the densities of various seagrass species and the presence of different algae types.
“Seagrasses, being living organisms, thrive on resilience,” explained Dr. Chris Anastasiou, Chief Water Quality Scientist. “The healthier they are, the better they can withstand challenges like hurricanes or red tide events.”
To support these ecosystems, efforts such as reducing fertilizer use and properly disposing of pet waste are crucial. These actions help prevent excess nutrients from washing into the bay during rainfall, preserving the delicate balance of the aquatic environment.
This means limiting fertilizer use and picking up animal waste to prevent those extra nutrients from ending up in the bay after it rains.
Dr. Anastasiou joined Amanda Holly on her podcast this week to discuss the health of seagrasses in Tampa Bay over the years and what we can do to help keep them healthy.
