Key lessons
The revitalisation of the Scarpe River led to an improvement and a diversification of its related aquatic and terrestrial habitats. Therefore, this project participated in enhancing the ecological status of the river, expected to be good by 2021. The perception of the population was very positive thanks to the amenity space provided. However, the fact that the work took place from the river made its realisation difficult and a population of gooses is now disturbing the growth of the planted vegetation.
