Iasi is a city with a relatively high number of parks and this NBS is part of an initiative of the municipality of Iasi to restore green area affected by the passage of time. The green space in the Orăşel Park was inhomogeneous as vegetation with unpopulated areas of trees (the centre of the park) in contrast to agglomerated vegetation areas.
The growth of woody vegetation had in some respects changed the appearance of the landscape ensemble, creating agglomerations of shrubs and trees. As such the municipality took the decision to rehabilitate the area (1)

The city of Leipzig initiated the project "Für eine Baumstarke Stadt" in 1996 to integrate community support into the greening of Leipzig through tree planting. Citizens can become tree sponsors with a donation of 250 Euros or more supporting the increase of the tree stock in parks, on the street and at squares since they are planted in addition to the tree stock determined by the city department for urban green. The sponsorship includes a sign with the indication of the tree species and a personal message. This programme contributes to a greener city landscape and strengthens the attachment of citizens to their urban environment (1, 2, 3).

This NBS comes as a reply against the municipality of Iasi which in 2013 cited lack of visibility and aesthetic preoccupation decided to cut over 100 linden trees and replace them with Japanese acacia in the city centre.

As such in 2015 the municipality re-planted the linden trees (1).

MFO park is one of the green infrastructures in the city of Zurich. Instead of designated space between paved streets, MFO-Park uses the structure of an old factory building as its skeleton, taking the form of a multilevel building that seamlessly fits into the surrounding structures.

MFO has received a series of awards, including recognition as the “Most Innovative Contemporary Park or Garden”– a prestigious designation from the European Garden Heritage Network (Ref 1).
