The Utinga State Park (PEUT) is one of the few green areas with the function of preserving biodiversity left over from the urbanization process in Belém. Added to this is the fact that the effectiveness of controlling the use of the park is directly linked to maintaining the quality of the water supply, since it is home to the city's so-called "water barn". In this context, the idea of environmental protection involves different perspectives, which are directly linked to the challenges of sustainability in the face of metropolitan development patterns. Generally speaking, the creation of an environmental park in an urban area is linked to the idea of preservation and quality of life through environmental services to society by filtering air, water, wind and noise pollution; stabilizing the local microclimate; creating a space for environmental education and visitation that positively influences mental and physical health, as well as providing shelter for native wild animals or those introduced to the area.
