Tree Supports—A Method for Managing the Protection of Habitat Trees, Increasing Biodiversity and the Resilience of Urban Ecosystems

Protecting valuable trees with habitat significance in urban environments is not a new problem; however, it has only been addressed to date based on practitioner experience, rather than a proper scientific foundation. The lack of a developed methodology and the failure to combine tree measurements and assessments with structural calculations often led to failures, destruction, and damage. The proposed method, based on static studies, calculations, and an action algorithm, enables effective responses and the creation of tree-specific solutions. This article presents an analysis of solutions based on 10 years of research on over 1500 trees. The method supports the long-term preservation, protection, and conservation of valuable habitat trees, which are crucial to the urban ecosystem. This paper presents a new algorithm for managing conservation issues, along with methods and examples of its implementation. The methodology has been tested on real-world examples and is recommended for use in new cases of valuable trees identified for protection. Building ecosystem resilience and increasing biodiversity, especially in urban areas, requires implementing solutions grounded in research rather than relying solely on implementers’ experience.
