Description of context
Rennes urban green space differentiated management falls within a sustainable development policy (environmental safety, recognition of the inhabitant's social request to have local natural green space, maintenance expenses discount). The differentiated management is the conception, management and implementation of ecosystems (which are under the different level of human influence) which correspond to different social needs. It is not an opposition of the horticultural management of green spaces: it is a method which allows, in the same city, managing a range of different green spaces area, from the most "sophisticated" flowery parks to the most rustic spaces.
Description of project - background
Since 1980’s, the city has adopted a new approach- the differentiated management. Thus, it has started to modulate green space management in order to develop an extensive management of some spaces, in rupture with usual intensive practices which is the rule in France impregnated by the pattern of “jardins à la française”. The intensive management is characterised by a strong human intervention (use of pesticides, fertilizers...). On the opposite, the extensive management (hands-off management) is defined by few human interventions.
