Green space and habitat

The project of building 100 butterfly booths in different locations of the city developed by BUND Bremen in cooperation with the Botanical Garden, Stadtgrün Bremen and implemented jointly with the citizens. The project additionally involved plantings of flowers and educational activities. It aimed at increasing biodiversity, increasing the protection of the endangered butterfly species as well as providing care instructions for the care of butterflies for the residents of Bremen (Ref. 2, 3).

The aim of the FitzSimons Wood Biodiversity Education Programme is to highlight the value of, and to promote the use and care of biodiversity and green space in the local area through learning exercises and activities taking place in FitzSimons Wood park. To support such educational activities in the park, enhancement of the habitat was carried out by developing footpaths, planting native trees and management of invasive species. Also, a detailed handbook for school teachers was produced with guidance on how to lead school activities where students investigate local wildlife. (Ref. 1; Ref. 2)

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).

Creation of an additional spot for a vegetable garden, which is a utility of the charitable society for inclusive employment (Gesellschaft für integrative Beschäftigung mbH) in Bremen. With the land provided by the city and with the financial help of Aktion Mensch organization the initiative aimed to establish an additional area for the gardening and horticultural activities that will involve disabled people. The project aims to increase social inclusion of the disadvantaged groups as well as promote urban subsistence and sustainable solutions in food production. The initiative also involves educational activities (Ref. 2, 3).

The two-year project "Integrationsgärten" aimed at the creation of three social integration gardens for refugees at different residential districts: transitional house Arbergen 2 (2016), a transitional house at Tannenbergstraße (2016/2017), and in Huckelriede (2017). The project involved various gardening activities and cultural events that aimed at increasing social integration of the refugees, improving their language skills, as well as stimulating neighborhoods to social engagement and participation in environmental issues in the neighborhood (Ref. 2, 3).

A pilot educational garden was created by Foundation Zaedno in Sofia in 2011 in the city kindergarten Slaveyche. The initiative was carried out with the financial support of Charles Stewart Mott Foundation and volunteers. The aims of the garden were to turn a derelict site into an attractive place for learning about and practicing gardening, playing games, learning about healthy nutrition, conservation, and promoting the creation of other Delicious Bio-Gardens. The garden has herbs, vegetables, and a rainwater harvesting system. Events connected to this initiative were taking place till 2013-14 (Ref. 1; Ref. 2; Ref. 4)

The renaturalization of the water canal Hirtenbach project was part of the larger city-wide initiative that aimed at the naturalization of different parts of the city's drainage system including small trenches and streams. The initiative aimed to decrease the risk of floods, improve the water quality, protect the local flora and fauna from the pollution, as well as provide for an additional recreational area for the citizens. (Reference 1)
In 2000, natural remodelling or the creation of near-natural structures began in sections. A 20, 000 m3 retention basin was also built. These actions improved flood protection and ecology of the area, and it provided local recreation opportunities. However, a study conducted in 2014 revealed that the restoration measures brought positive changes, but it was not enough to achieve a “good water status” defined by the European Water Framework Directive. Intensive care from silting and lush plant growth, wide margins, and the reduction of nutrients coming from the drainage and agriculture, need to be addressed. (Reference 2)
A new landscape is expected to be created when the alder trees grow. Waterbirds and waders, as well as insects like dragonflies, bees, butterflies and crickets, have been observed in the area (Reference 3).
The large drainage system of the city of Hannover includes many small trenches and streams with a total length of 152 kilometres. The intervention in Hirtenbach involved renaturalization worked on the total length of approximately 10,5 km (of which 3,3 km in the urban area). (Reference 2)

Rehabilitation of the public green space of the Park Krekovic through employment of people with a risk of social exclusion. The initiative cleaned the green areas of the park, rehabilitated the gardens with planting actions, and maintained the overall infrastructure. (ref 4)

Green roofs were created on vehicles in the Spanish cities of Barcelona, Girona, Córdoba, Valencia. This initiative is based on the project of Marc Grañén, who developed PhytoKinetic a project for the development of moving gardens. (ref 1) The city of Palma de Mallorca was also considering its introduction as a measure of sustainability. (ref 1) The intervention, however, remained in the pilot stage (ref 1 and 4).

The “Animal Species Aid Program”, also a part of “More Nature in the City” project of the Department of Environment and Urban Green, mapped out the occurrences of wild bees in Hannover including Leineaue, Alte Bult and the area of Berggarten and Leibniz University. With this program, 244 wild bees and wasp species were detected in Hannover in 2013/2014. In addition to the inventory, the program has also provided care instructions tailored to the individual species (like frequency and timing of lawn mowing) in order to protect their habitat.

The “Wild Bee of the Year” was launched in 2013 by the Baden-Württemberg Wild Bee Cadastre Working Group in cooperation with the State Institute for Bee Science and the beekeeping associations of Baden-Württemberg to draw attention to the danger to native wild bees throughout Germany. The program is part of the city of Hannover’s activities on biodiversity. As an example, in 2012/2013, occurrences of the endangered nightingale were recorded, extremely rare and highly specialized tree beetles were mapped, and amphibians and dragonflies were stocked in selected small waters. Specific care measures for individual biotopes were provided along with an overall overview of the ecological qualities of the city of Hannover.
