Two excellent projects focused on preserving or restoring the natural biodiversity: In Rouen (France), the Port Authority HAROPA, has developed between 2017 and 2019 a project to restore the wetlands connected to the Seine river in Sahurs. The new structure and water canal allow the tide to reenter the area and recover the natural environment of the estuary. In 2020 the port authority planted flora improving the integration of the site in the landscape and installed educational panels. In Bahía Blanca (Argentina), the Marine Wildlife Rescue Station has helped more 115 animals from 15 different species, over the past two years, since it was created. This facility is the result of the cooperation of the port authority of Bahía Blanca with several environmental organizations.
