Here is an excerpt: "There are many native species in the parks that play a critical role in supporting a healthy ecosystem. These native species make a beautiful place to visit without the addition of harmful chemicals and synthetic fertilizers that pollute our waters and contribute to the vast deadzone in the Gulf of Mexico. For example, have you noticed the clovers coming up through the grass? If we carefully dug one of them up, we would see little white nodules on the roots. A little bacteria is inside that little nodule that has the ability to pull nitrogen out of the air and place it right on that root. As the free-nitrogen feeds the little bacteria, the plant gets fed some nitrogen, too. This is why clover is called a nitrogen-fixer; it provides natural fertilizer for all of the other plants in the soil. Not only are the clovers beautiful, but because you let them grow in your park, fewer chemicals need to be added to the park, which keeps the water cleaner and all of us healthier."
