Habitat and biodiversity conservation

The Sunderland Greenspace Audit explained the city's green space in detail and set guidelines and standards that will help to ensure that all areas of the city have a range of quality green spaces available to them. Hereby the Sunderland City Council wished to improve the green public spaces to retain existing residents and attract new ones, to enhance the image of the city and for it to be used as a means to attract future investment in the form of new shops and jobs (Ref 1).

The Aa promenade, created in 1950 to provide the citizens of Muenster with a green experience trail in the inner city, was redeveloped in the 90s with several planting measures on riverbanks, walls and in adjacent areas. Next to a brochure, a nature trail which combines the existing recreational with an educational component was created with 18 site-specific signposting points. They cover multiple benefits and ecological functions of urban green spaces, city trees and green facades/walls (microclimate regulation, air quality, CO2 capture), anthropogenic threats, unknown biodiversity hotspots and natural monuments (Ref. 1, 3 and 6).

Bute Park is a riverside green spot with an arboretum and gardens, containing a broad range of ecosystems supporting a wide variety of living species (ref 4). The historic Mill Leat had been dry since the 1970s."The word "leat" refers to "an open watercourse conducting water to a mill". The Mill Leat sits on the same site as a former millpond at the end of the original medieval millstream. It supplied water to corn mills located to the south of the Wst Gate and contained water well into the 1970s." (Ref 10) .Mill Leat Restoration or the re-flooding of the dry water body was a major deliverable under the Bute Park Restoration project (ref 2). In 2013 the overgrown channel was excavated, lined and refilled with water as part of the Bute Park Restoration Project (Ref 2). It enhanced the character of the park and provided a new habitat for wildlife (ref 1). Now re-flooded, Mill Leat is self-contained, self-regulating and self-circulating. It has reduced the risk of flooding and created a sustainable water feature (ref 2).

Monglong Park was rehabilitated in 2012 with the explicit aim of strengthening social ties. The site is a wooded area of 4 hectares to the south of the Bellefontaine district. Unknown until its redevelopment, it constitutes a true ecological niche for the city and has great biological richness and landscape. The associations of gardeners and the gardeners of the Bellefontaine neighborhood, including the Maghreb and Mong communities, were involved throughout the construction of the park (Ref. 2).

The Park Killesberg serves as the green centre of the newly constructed district in Stuttgart and continues the long history of the area as a garden show site with a contemporary expression of landscape architecture and as a model for interconnected green spaces. The design is the result of a collaborative process with the local authorities, citizens and neighbours (1).

The initiative involves establishing beehives on the roofs of the Catholic University of Lublin and the Centre for the Meetings of Cultures. It seeks to provide the habitat for the bees in the city, help in pollination, educate the society about the bees and shape more ecologically-friendly attitudes among the students, faculty and visitors. It should also produce honey that can be sold or distributed free of charge, which can serve in a promotional tool of the two institutions. The Centre for the Meetings of Cultures has additionally opened a garden to provide food for the pollinators [1,2,3,4,6]. In 2020, the initiative is still ongoing and expanding. Every year, the university organizes a competition about the life of bees for various age groups [7].

In 2008, the wilderness experience garden and laboratory was founded on 2,500 sqm of nature area in Münster by Annika and Olaf Bader, two pedagogues. With grasslands, hedges, fruit trees, a treehouse, beehives, a yurt, a fireplace and many more elements it’s a place for nature experience and exploration for children and adults. Guests are encouraged to engage with nature scientifically, via play, arts or manually. Based on a hands-on approach, there are also vocational trainings for extracurricular education providers offered (ref. 1 and 3).

The historical canal that was disconnected by a road in the 1970s is currently being restored by the municipality, creating a lively atmosphere allowing for water recreation, a boulevard and green spaces (ref. 1). A small element of this restoration is the addition of green elements by a citizen group, which entails improving ecological, aesthetic and historical quality of the canal by implementing eco-friendly riverbanks, green connecting zones and floating vegetation islands (ref. 3,9,11,12).

Wakefield Council is "responsible for managing over 2650 acres of grass in parks and countryside areas across the Wakefield district (this includes cutting the grass)". Since 2015, there are small areas where "the grass is being left to grow" naturally for environmental benefits. (Ref. 1) The objective of the project by leaving derelict some grass areas are that "the environmental benefits of leaving some grass to grow naturally include encouraging wild flowers to grow which will support bees and other insects, and aiding drainage to reduce flood risk" (Ref 1).

Urban gardening or gardening in the city is a form of agriculture that is about more than just producing food: community gardens involves also social, cultural and political components. It's about actively participating in urban development, creating new living spaces or making a contribution to biological diversity (ref. 3). The campus garden on a surface area of 1,200 sqm provided by the university was created by a group of students in 2013. It is open every day to everyone interested in gardening and serves as a place for recreation and exchange for students of different disciplines and citizens. Apart from herbs, vegetables and fruits, also flowers are planted. Seeds and materials used as plant beds, such as tires or rice bags are often donated from the city or local businesses (ref. 3 and 4).
