Nutrient pollution in Florida’s waterways is a critical problem, fueling repeated harmful algal blooms in coastal waters. In the Indian River Lagoon, a critical manatee habitat, such harmful algal blooms have destroyed native seagrass, resulting in the deaths by starvation of hundreds of manatees. Over 2,000 manatees died in Florida between 2020 and 2022.
Together, we can protect these critical habitats for manatees, other aquatic life, and for our own future generations by reducing human sources of pollution such as fertilizers, improperly-treated sewage, leaking septic systems, and stormwater runoff. While Save the Manatee Club works with our partners to strengthen policies that protect water quality, the individual actions of each Florida resident can make a big difference for the health of our waterways. Do your part: take the pledge to be Fertilizer-Free for Manatees!
Take the Pledge!
I pledge to be Fertilizer-Free for Manatees by:
Avoiding fertilizer use on my lawn and landscape
Conserving water by irrigating my lawn only when necessary
Keeping grass clippings out of streets, waterbodies, and swales
Excess fertilizer presents a hazard to our waterways and in turn, our manatees. Fertilizer that is not taken up by plants runs off your property and into our waterways, creating algal blooms that kill seagrasses and harm manatees. Most established landscapes do not need fertilizer at all. If you suspect your lawn needs to be fertilized, get a soil test first. Your local Extension office can help.
Did you know that more than half of our monthly water use is from irrigation and that many lawn issues (such as dollar weed and grass fungus) are caused by overwatering? Save your lawn and your money by cutting down on irrigation. Install a rain sensor or watch the weather and only turn on your system on when needed.
KEEP GRASS AND YARD DEBRIS OUT OF WATERWAYS, SWALES AND STREETS
Grass clippings contain nitrogen and phosphorus that can contribute to algal blooms in a similar way to fertilizers. Instead, keep them on your lawn and recycle those nutrients back into your soil.
