It is generally recognized in modern urbanism that the environment plays a significant role in the quality of life of citizens. Many researchers place a heavy emphasis on the environmental, social, economic, and systemic functions of so-called green spaces in large cities. Meanwhile, in practice, natural territories are often perceived only from the perspective of managing recreational activities. The state and the form of nature in the city remain the subject of debate. To develop the right approach, a fundamental question must be answered: What should “wild” nature be like in a metropolis. A review of the modern literature demonstrates that city dwellers prefer to relax in natural or nature-like areas that have a natural vegetation structure and limited elements of urban landscaped parks. Given the choice, most people prefer areas with a biotope having a mosaic structure with complex and diverse arrays of plants and other vegetation. However, preferences vary across countries depending on education, culture, traditions, and social status. Attitudes toward nature in cities fluctuate constantly and can shift along individual experiences and urban milieus. A particularly significant issue in modern cities is children’s limited contact with nature, and over time, each generation finds itself living in an increasingly attenuated natural environment.
