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)

Renaturalization of the water canal Hirtenbach
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)

Krekovic Park green rehabilitation
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 on buses
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).
