The "Regulation on the protection of trees and the development of green areas in Wrocław" was issued by the Mayor of Wrocław in Poland in 2016 and updated in 2019. The overarching objective of the regulation is to promote tree protection measures and development of green areas in the city. The regulation obliges municipal units and other actors that manage land and buildings on behalf of the city to conduct actions to protect and maintain in good condition as many trees as possible. It contains specific actions that need to be undertaken during interventions in green areas or during construction work to protect the trees. When keeping the trees is not possible, it mandates that new trees are planted in compensation and provides detailed instructions regarding the species and location of the newly planted trees. The regulation mandates creating of a database that contains information about the urban greenery in Wrocław and all planned tree plantings and removals. The regulation was created in order to implement the policies for green spaces and environment outlined in the binding Study of Conditions and Directions of Spatial Development in the city of Wrocław, as well as the environmental priorities of the Strategy Wrocław 2030, which is the city's masterplan.
