Current state of green spaces of the Kologriv zootechnical technical school (Kostroma region)

or the effective involvement of cultural heritage sites in the tourism sector, the preservation of historical memory, and the implementation of comprehensive restoration work, studies aimed at identifying the range of plants, the spatial-planning structure of green spaces and assessing their current state are of particular relevance. The purpose of the study is to assess the current state of green spaces on the territory of the former Kologrivsky Lower Agricultural Technical School named after F.V. Chizhov (Kostroma Region). The study used a set of methods: historical and archival analysis, field surveys and a graphoanalytical method. During field studies in 2023-2025, an inventory of green spaces was carried out, their sanitary condition was assessed, and the species composition of undercanopy plants was studied. A complex spatial-planning structure of the territory was revealed, including a linden alley and a landscape park with fragments of regular planning and trees aged 180-190 years. The tree plantations are in a weakened state, and the share of drying and dead trees reaches 26% in the alley and 35% in the park. Successful natural regeneration of linden and elm is noted under the canopy of the park. In general, a decrease in biodiversity and a threat of losing the preserved historical assortment of trees and shrubs are predicted in the coming decades. The widespread distribution of Sosnowsky's hogweed on the territory of the complex and the use of chemical methods of controlling it create a threat of physical loss of the park landscape. The results obtained in the course of the study indicate the need to develop and implement a set of conservation and restoration measures, including forestry ones for the care of plantations and improving their sanitary condition. The study results form a scientific foundation for developing preservation and restoration measures, applicable not only to this particular object but also to other provincial historical parks in central Russia facing similar conditions.
