Maintenance and management of urban nature

"The Imperial Canal of Aragon acts like a green corridor crossing the city of Zaragoza from Montecanal to Torrero and passing through Casablanca and the Great Park." (Ref 2) The more than 200 years old waterway runs through 7 regional parks and green areas and it is 41 km long. (Ref. 1 and Ref 3) Its rehabilitation has been planned in 2003 for parts of the canal with bike paths built, pedestrian walkways, strengthening of its hydrological structure, and protection of its greenery. (Ref 6)

A nature park in Bucharest containing the wetlands surrounding Lake Vacaresti. It was initially a swamp drained by the communist regime, which builds a complex of apartment blocks. In 2014 it was declared protected by the Romanian Government and named Văcărești Nature Park, and was approved as a natural protected area in 2016. (1)

With the decline in industrial use, the grey harbour landscape of Frankfurt am Main became a habitat for rare plants. In 1986, the city council ordered transformation of the former industrial area into a public green space between the Main and the new residential area in the Ostend. The bright, spacious park with 2.1 ha surface was finished in 2000 (1) now welcoming locals for recreation and exercise while it also hosts a cultural summer festival and gives a home for local wall and fence lizards (1).

In the context of significant cuts to Newcastle City Council's budget, the issue of how best to maintain the green space in the city integrated into, and surrounds, social housing has emerged. A proposal to allow, or promote, the re-wilding of these spaces (e.g. changing turfed areas to wildflower gardens) was discussed in March 2017. The key driver appeared to be the potential to reduce the costs incurred by the council in the maintenance of green spaces around social housing. (1)
During a Naturvation project meeting in March 2017, the potential for contestation around this proposal was discussed and seemed to be considerable (e.g. re-wilded green space might not be considered aesthetically pleasing by residents and might not provide preferred functions such as space to play sports).

The aim of the project was to protect and enhance the areas of core nature conservation interest and adopt environmental management principles to help reduce the impact of management operations on the environment. Linn park and Local Nature Reserve (LNR) is the second-largest park in the city. Linn Park comprises a mosaic of riparian woodland along the White Cart corridor principally broadleaf in character, mixed woodland plantation blocks connected by a series of mixed-species shelterbelts, scrub, meadow, amenity grassland, and parkland trees. The woodland provides habitat for a great variety and number of birds both resident and migratory. Some areas of the woodland have good ground flora diversity including the occurrence of Bluebells (Hyacinthoides non-scripta) in patches.
The park is particularly of note for its floristic and bird diversity with some 250 and 60 species recorded respectively. Some animals and plants of interest include Atlantic Salmon (Salmo salar), Otter (Lutra lutra) and Kingfisher (Alcedo atthis) and Great-spotted Woodpecker (Dendrocopos major) and Toothwort (Lathraea squamaria) in the woodlands. It is scarce in Scotland and Linn Park and is one of only 3 sites in Glasgow this species is found (Ref 4). Linn Park and Local Nature Reserve (LNR) was awarded a Green Flag in 2013. The Green Flag Award is the benchmark national standard for quality parks and green spaces (Ref. 3).

The Green Axis is a belt of green areas and parks that stretches all the way from the Public Library of Bergen to The National Stage. It entails several parks, including Byparken, Ole Bulls Place, Logebakken, The Theatre Park and King Olav the 5th's Place. The Green Axis holds several culturally important buildings, statues, and landmarks. This green oasis in the heart of the city provides habitat for species and increases well-being for the citizens of Bergen. (Ref. 1, 2) The area is continuously upgraded with high maintenance standards. (Ref. 5)

The aim of the project was to plant many varieties of vines on flood embankments of the southern tip of Ostrow Tumski on a stretch of 1 km. Grapes would be free of charge, as the idea of the project was to set up a community garden where the effects of the citizens’ work would be available long-term and publicly accessible [1]. In 2014 the project was in a pilot stage which resulted in a successful application for funds from the participatory budget in 2016. Despite the awarded money, the project has never been implemented, hence the applicants (Foundation “Vineyards of Poznan”) pressed charges against City Hall. Today, the project is still in the initial form from its pilot phase [9].

Nygård Park is an old, large park in central Bergen that has been undergoing transformation since 2014, as the park had degraded over the years and had been heavily used by drug users (Ref. 6). The restored park serves to act as a natural meeting place in the city, consisting of green areas, a pond, playgrounds, flower beds, an amphitheater, walkways and much more. The restored park retains its traditional British design, and also includes a more universal character allowing for more users of the park and facilitating access to the different parts of the park. (Ref. 1, 2).

The project created a green recreational park in the family housing area, where there had been a lack of such facilities. The park contains a multifunctional sports pitch, open-air gym and a playground. Additionally, as the park is located next to the nature reserve ‘Żurawiniec’ it serves as a buffer zone for the reserve and mitigates the pressure caused by the proximity of the city [1].

The project area comprises the morphological floodplain of the Rhine to the north and south of the city of Karlsruhe and sections of the river Alb, covering an area of about 7.665 hectares in total. Alongside Karlsruhe, five smaller communities in the neighbourhood contribute to the project as partners. Due to the channelling of the Rhine, the construction of dykes and the isolation of river channels, the area has lost its natural floodplains and precious habitats and became more vulnerable to flooding. Major objectives of the project are the re-introduction of natural floodplains and the enhancement of natural habitats for local flora and fauna. (Ref. 7). The project included an exceptionally wide range of measures including species protection measures, the complete desludging of parts of the Rhine, the re-establishment of softwood and hardwood forests typical of the floodplain, the construction of bridges, the natural remodelling of the entire river Trench systems and the creation of new bodies of water. (Ref. 9) The project also provides environmental education, informing the public about activities and encouraging their participation (Ref. 7)
