Create new habitats

The park of Dondaines is an agro-urban park of the city. This contrast is guaranteed by the ecological management of space that aims to promote biodiversity in this highly urbanized area. The Park of Dondaines is located in a strategic position, between the old and the new Lille, and creates a link between these two entities. The park hosts a pedagogical farm. It is a framework where the urban, the animals and the plants meet. It preserves plants and small animals by providing them with food and habitat. The cover of the periphery, planted with pines, ensures the continuity of the park with the new districts of Euralille(Ref 3).The place is a garden of representation, park of proximity, urban agriculture and food production space, pedagogical farm and event platform, and a place for sports and games (Ref 2, 5).

The Garden of (Re) Finds, was born in Lille in 1997. It is the first "community garden", directly inspired by the model of the gardens New York, which was created in France (Ref 1). There is an organic vegetable garden, a scented hill, a rainwater harvesting system, a regional hedge of regional species, a compost corner and a convivial shelter in corded wood and vegetal roof (Ref 2).

Hamburg decided to increase the number of trees in the city, however, the budget was not enough to completely fulfil this goal. Therefore, the city not only tripled the municipal budget dedicated to tree planting and but began encouraging the citizens to contribute to greening the city through the donation campaign "My tree - My city”. The project was launched in 2011 as part of the European Green Capital programme of Hamburg. Citizens can donate and by using an interactive map, can choose a site and a tree species to be planted, and follow-up the implementation of their tree. (Reference 1, 3) The City of Hamburg gave for each tree that reached donations of 500 Euro the same amount on top to cover the average costs of 1.000 Euro per tree, which includes the preparation of the planting pit, the planting itself and maintenance. (Reference 4) The campaign was so successful that it continued even after Hamburg’s year as the European Green Capital and is still going on in 2020. (Reference 2, 7)

Opened in June 2006, the Jean-Baptiste Lebas Park, which occupies a space once used for illegal parking and marred by 11 lanes of traffic, is surrounded by the boulevard of the same name. This park plays an important role in creating an urban green space into a derelict grey area. The park helped to increase the biodiversity of the area. It has an area of 3-hectare (7-acre) and it contains a large lawn with flowerbeds, play areas for children and places for playing "boules" (Ref 1).

Zollverein is an abandoned colliery and coking plant near the center of Essen in Germany (Ref. 6). Since 1993 the mining here stopped, and the site was turned into a derelict area, so nature could win back its territory. Most of the railway tracks and the smaller industrial leftovers are now covered with moss, grass, and weeds (Ref. 4). After the site was recognized as a World Heritage Site in 2001, it started being developed as a multifunctional cultural, tourist and recreational center keeping and developing biotopes that emerged over time (Ref. 11).

"The Conservatoire des Restanques is dedicated to preserving biodiversity (conservation orchard, forgotten vegetable garden, Mediterranean garden with the typical plant species of low limestone Provence) and to be a showcase of the current considerations of Sustainable Development (energy, waste management, water resources management, etc.). The development of the site and the different elements of the landscape make it possible to develop educational programs on the themes of flora diversity, wildlife, heritage conservation, food, consumption and health, eco-construction and energy management" (Ref. 3).

A 21-kilometer regional cycle and footpath between the cities of Essen, Mülheim am der Ruhr and Duisburg was developed from the former unused railway route of the Rheinische Bahn. The path was landscaped to ensure the comfort of pedestrians and cyclists. Part of the route passes through Emscher Park and become a full-fledged part of the green infrastructure of Essen (Ref. 1).

The Newton and Arkwright roof, buildings of the Nottingham Trent University campus, holds one of the region’s largest sedum roofs, which spans its way 2,500m² across the building, creating a home for 13 varieties of sedum, insects, songbirds and a new colony of honey bees, creating a trio of hives over all campuses (ref. 1). A 150m2 bank surrounding the building is unmown in order to promote biodiversity and attract pollinating insects in the summer months. Green-walled gates was also part of the implementation activities of this project. (ref. 5).

The “Cities Dare Wilderness” project is part of the overall Hanoverian program of “More Nature in the City”, a new future-oriented approach to green spaces in urban areas. The aim of the project is to bring wilderness back to the city by increasing urban biodiversity, strengthening nature in the city and making it habitable for its inhabitants. For fulfilling these goals, eleven sites were chosen (some parts of the city park Eilenriede, some currently intensively cultivated areas or some derelict small gardens), in which different methods have been tried out, like planting local woody plants, grazing, and the implementation of interpretive trails. The development of the flora and fauna in the new wilderness is now being observed and investigated. The first step in the wilderness was made on a meadow along the course of the Fße in the Badenstedt which was fenced. It was made available for cattle to graze and influence the new growth of shrubs through feeding preferences (Reference 1, 2). The flowering meadows have attracted a variety of species. The rich habitat resulting from the project has attracted songbirds, hedgehogs, butterflies and some of the 67 bee varieties endemic to the state of Saxony (Reference 10).
Campaigns for environmental education are regularly offered in order to involve the population in the process of wilderness development. The series of “Wilderness Concerts” were organized, a “wilderness woodlice” was installed in one of the project areas (Mittlefield), and handicraft activities have been regularly offered, in addition to excursions and guided tours (Reference 8). Citizen science is also part of the project through the iNaturalist app that allows the community to record observations of the flora and fauna in the area (Reference 9).
The project is financed by the Federal Ministry for the Environment, Natura Conservation and Nuclear Society. Two other cities, Frankfurt am Main and Dessau-Roßlau is also involved as model cities. (Reference 1,2)

The Ronald McDonald House is a temporary home for families with seriously ill children who are treated at the Essen University Hospital. The house was designed by the artist Friedensreich Hundertwasser, who merged the garden and architecture together in order to bring residents of the house closer to nature improving their psychological and health conditions (Ref. 1). The house was opened in 2005 in Essen's Grugapark (Ref. 2). A special highlight is the accessible intensive Green Roof (950 sqm) with grass, herbs, flowers, shrubs, and trees (Ref. 3).
