Invasive Non-native Aquatics: Good or Bad for Florida's Waterways?
6th Grade
Mrs. Logan

Florida's waterways have been exposed to many invasive aquatic weeds that have the potential to take over the natural ecosystem of our Florida waters. Invasive aquatic weeds kill fish and wildlife habitat and affect many of our valuable resources. While studying two different aquatic species, one that is non-native, and one that is native, I have collected data that supports the fact that non-native aquatic species are harmful to Florida's waterways. There are several factors that determine water quality. One of the most important variables measured, is the amount of dissolved oxygen in the water. Using a dissolved oxygen meter, or DO meter, I tested five buckets of water from the St. John's River over a five week period. Two of the buckets contained water hyacinth and the other two contained coontail moss. Water hyacinth is an invasive non-native and coontail moss is a common native plant. A fifth bucket was filled with water but I did not put any plants in it because it was the control bucket. I also checked the pH levels of the water before and after the experiment. The dissolved oxygen levels were, on average, lower in the buckets with the water hyacinth than in the buckets with the coontail moss. After the experiment was over I concluded that non-native invasive aquatic plants are harmful to Florida's water.
