Renovation of urban space is not possible without new approaches to the formation of green spaces of the landscape gardening heritage. In restoring parks-monuments of landscape art, simultaneous consideration of ecological and biological foundations, preservation of the historical structure of plantations and landscape planning framework, as well as meeting the modern needs of users of these spaces is an important issue. The research aims to formulate practical recommendations on the main ways to optimise the planning structure and green spaces, as well as means of protecting biodiversity in parks and monuments of landscape art. The study used general scientific methods (analysis and synthesis, field research) and special methods (dendrological, cartographic, historical, and architectural analysis, and computer methods for processing graphic data). During the pre-project stage of the study, the prerequisites for the formation of Zhovtnevyi Park in the structure of the Chernivtsi landscape were identified. A list and description of typical plant species typical for the area were provided. In addition, the pre-project study analysed conflicts in the park, which were divided into the following main groups: transport and pedestrian, functional, natural, anthropogenic, and visual. The interconnection of different types of conflicts and their impact on the conservation of biodiversity of green spaces in the park was revealed. As a result, new elements of the planning structure have been formed that improve the landscape-spatial organisation of the park's territory and contribute to the optimisation of green spaces. The project developed and analysed in this study has selected an assortment of plants that enrich the biodiversity of park plantings and can be used in the design of other urban parks. The example of the project for the maintenance and reconstruction of Zhovtnevyi Park in Chernivtsi demonstrates practical planning approaches and recommendations aimed at maximising the preservation of the natural landscape and enhancing its functional and artistic features
