Sustainable Ecology of the Metropolis and a Local Green Frame Involving Beneficial Insects on the Example of St. Petersburg

The article describes the results of design studies aimed at increasing the sustainability of the environment by attracting beneficial insects in the structure of the formation of a green frame. The work was carried out in 2021-2023, the vector of design research was formed on the basis of the St. Petersburg State University of Architecture and Civil Engineering (SPbGASU) undergraduate program and continues in the format of networking, including with the participation of Sevastopol State University (SevSU) undergraduate program ” directions “Landscape architecture”. The article describes both landscape and ideological practices that help attract beneficial insects to the territory of landscape objects, and also describes specific solutions on the example of the territory of the Petrogradsky and Kirovsky districts of the city of St. Petersburg, made with the participation of residents and the Improvement Committee. The importance of insects in the urban green network is described, the possibility of integrating special landscape zones into green infrastructure for this, the problem of creating a single ecological frame of the metropolis and a local green frame at the district level is considered. The author’s design methodology is presented in terms of the transition from the urban and town-planning level to specific design solutions at the masterplan level and, further, to the development of specific landscape niches with the landscaping species composition
