Hello,

Thank you for your contribution to the Suggestion Box.

We recognize the importance of brambles for biodiversity, as they serve as a refuge and resource (pollen, nectar, and berries, particularly in midsummer) for many species. However, the bramble is a pioneer species that rapidly colonizes open habitats such as meadows and forest edges. In certain areas of green spaces, its spread conflicts with priority uses (e.g., pathways or recreational areas that need to remain open, new tree or shrub plantings), and frequent management actions are necessary. In other areas, particularly those dedicated to biodiversity (well-developed hedgerows, piles of wood and branches, flower-rich meadows), our intention is to allow brambles to grow to a certain extent so that they can fulfill their role in supporting biodiversity, but to intervene when their growth becomes excessive. For example, when they prevent native shrubs from growing, when they rapidly take over a meadow, or when they completely cover a pile of wood or stones.

Since brambles naturally colonize many areas, there is no need to plant them. Plantings of native shrubs—particularly thorny ones—are preferred because they are easier to manage.

Therefore, your proposal was not selected. However, the City supports other biodiversity-friendly measures, such as wildflower meadows and native hedgerows, which also provide valuable habitats for local wildlife.
