A city-wide initiative for the protection of bees developed by the BUND Bremen together with a number of local NGOs, local government and the citizens of Bremen. The project involved the planting of trees and wildflowers that will serve as a food for pollinators in different parts of the city as well as the provision of additional nesting places for the bees. It aims to protect the endangered bee species, increase biodiversity and beautify the city with the new plantings (Ref. 2, 3).


Nature-based solution

  • Grey infrastructure featuring greens
  • Alley and street greens

Creation of new green areas

Project objectives

Half of 150 wild bee species in Bremen are on the highly endangered species list. The project aims to contribute to the protection of as many endangered species as possible (Ref. 2). Goals of the intervention: 1) To promote the urban replacement habitat for wild and honeybees in Bremen; 2) To introduce protective measures for bees and preserve biodiversity - stabilizing or even resettling some species; 3) To ensure survival of multiple wild plants that serve as food for pollinators; 4) To create more nesting spaces for the bees; 5) To develop optimal care concepts for flowering efforts; 6) To develop new structures that will make it easier for volunteers and sponsors to join the wild bees' protection efforts; 7) To beautify the city with wildflowers (Ref. 2, 3).

Implementation activities

Planting around 100 bee-friendly trees on private land that will serve as a valuable habitat for the bees (chestnuts, whitethorns, maples and linden trees); Planting wildflowers in the city (public space, private gardens, railway tracks) that will serve as food for pollinators; Developing public campaigns to promote the bee protection efforts (Ref. 2, 3). "Such a project can of course neither compensate for the loss of habitat in the countryside nor save wild bee species acutely threatened with extinction. But it can at least help to stabilize populations of some endangered wild bee species and, by the way, beautify the cityscape with wildflowers" (Ref. 2).
