In a new study that was the first to explain what some have long thought, researchers found that human activity helps sustain and strengthen the natural red flowers in Southwest Florida.

Led by researchers at the University of Florida, Sanibel-Captiva Conservation Foundation and the Sarasota Bay Estuary Program, the study found that while the combination of the elements that grow the red flower has consistently worked. the work of man in strengthening them over the years.

The researchers measured flowers in Charlotte Harbor and coastal areas involving nitrogen inputs from the Caloosahatchee River, Lake Okeechobee and the lake’s uplands. The lesson was published in a journal Environmental science.

“While the Red Sea is naturally growing, we have watched for a long time and have received evidence that human activity has helped to grow beach flowers in this estuary in various ways between 2012 and with 2021, ”said Miles Medina, lead author of the study and a research scientist at. UF Center for Marine Management.

Deciding what to do to strengthen the Red Sea is important for coastal states, because the harm done by these arrows affects humans and the ocean and terrestrial creatures.

However, it is difficult to find a fundamental link between human activity and the red flower for researchers because of the complexity of the flowers and the many factors associated with them. The center and its partners analyzed data taken from the Caloosahatchee River, Charlotte Harbor, beaches and waterways, protected by cities, residential areas. and agricultural land uses. They saw the influx of nitrogen from the coastal and upstream sides of the river – starting with the Kissimmee River, flowing into Lake Okeechobee, then into the Caloosahatchee River and finally. in the estuary – has always strengthened the flowers of the harbor.

“This study confirms that low nitrogen can prolong the Red Sea,” said research author Christine Angelini, director of the Center for Coastal Solutions. “However, it is important not to jump to conclusions and immediately assign‘ blame ’for red tape to a land use because other factors are related to the level of impact of the redundancy process. Canada.”

Dave Tomasko, author and director of the Sarasota Bay Estuary Program, explained that for more than a decade the state of Florida has acknowledged the highest nitrogen levels from the Caloosahatchee River.

“Our paper only shows that there are other benefits to reducing nitrogen loads such as reducing the amount of red sea that is coming to our shores,” he said. “Normally, if we do what the state decides needs to be done, we not only benefit from the oxygen and the cleanliness of the water and vegetation in this stream. , but it also helps to reduce the effects of a future Red Sea. “

This study is just the beginning to see the effect of human activity on the red flower.

“The UF Center for Coastal Solutions and our partners are using big data and cutting -edge tools to model, data and industry intelligence to increase the scientific understanding of the Red Sea and the other water problems on the beach, “Medina said. “And to better understand these flowers, we need to take a closer look at the entire stream and the Gulf and how the water is infused with organic matter and biological processes and processes. chemistry in the harbor. ”

The source of the sour green flower was discovered and the effects were stinky
