In this article, we took a walk-exploration of a piece of paradise called Turkey Creek in the center of Florida. Enjoying the spring period of the awakening of nature, accompanied by a multitude of birds and other unique sounds of the inhabitants of Turkey Creek, we paid special attention to the diversity of lichens, which, as bioindicators, react and reflect the state and quality of the environment. Lichens are very sensitive to air pollution and die when there is a high content of carbon monoxide, sulfur compounds, nitrogen and fluorine. The degree of sensitivity varies among species, so they can be used as living indicators of environmental cleanliness. Based on the composition of lichens, the concentration of various pollutants in the air can be quantified using developed scales and formulas. Lichens are a unique group of lower plants. Lichens combine two organisms with opposite properties: an alga (usually green), which creates organic matter through the process of photosynthesis, and a fungus that consumes this substance. Lichens are characterized by fairly high tolerance to climatic factors and sensitivity to environmental pollutants and are widely used as environmental indicators. Lichens contain many macro- and microelements, organic acids, hormones and enzymes. Vitamins are produced by lichens in very small quantities. Lichens produce specific substances that are not found in other organisms (lichen starch, lichen acids, etc.). Lichens have the ability to extract various elements from the environment and accumulate in their thallus. The number of currently known lichen substances exceeds 250, of which 75 are found only in lichens. Lichens are indicators of the environmental situation. Our goal is to find out whether recreational load affects the state of the environment in people’s recreation areas. We carried out our study of the state of the environment in the state of Florida in the Turkey Creek natural park. This territory was chosen because the natural complexes of the area are characterized by high environment-forming, environmental, and recreational significance. In the last decade, the anthropogenic load on ecosystems associated with the recreational use of the territory has been increasing. It is worth familiarizing yourself with the types of lichens that were seen in the study area. Keywords: Turkey Creek, biomonitoring, bioindicators, bottom fauna, lichens, ecology, biodiversity.
