Preserving and developing biodiversity

Strasbourg has introduced a blanket ban on pesticides within its parks and gardens and introduced differentiated management of green spaces.

Zero use of pesticides

Since 2008, the City and CUS' parks and green space departments have stopped using pesticides in public parks and gardens.

This policy has a triple purpose:

  • Protecting the health of citizens and the City's gardeners,
  • Protecting our groundwater, the urban community's major source of drinking water,
  • Protecting and developing biodiversity in the City.

A tailored approach to the upkeep of open spaces

Our gardeners are having to change their approach in several ways:

  • Tailoring the upkeep of each space to its particular purpose, its features and the number of people using
  • Using alternative methods to chemical weed control, by using heat, mechanical and/or manual methods.

The new system is factored into the design of all new public spaces.

Differentiated Management

All the green spaces in the city of Strasbourg have been divided into six different categories, each of which requires different management and upkeep techniques.

Each category has its own upkeep profile, and this is what we call "differentiated management".

Developing biodiversity in the city

A number of measures have been adopted to drive urban biodiversity:

  • Abandoning the use of pesticides, which can be harmful to soil flora and fauna (especially earthworms and microorganisms). Soil with a thriving microorganism population encourages plant growth and provides better resistance against drought, excessive rainfall, disease and parasites.
  • A return to planting local plants when possible. Plants that have adapted to the soil and climate of the region need less watering and are better equipped to resist disease.
  • Increased use of hardy, perennial plants which need less water. Annual plants often require much more care and their use is being limited.
  • The introduction of beehives and orchards into the city, thereby highlighting the nutritive value of urban gardens and the essential roles of bees in pollinating fruit trees
  • The creation of natural and flowered meadows to encourage the return of a richer fauna, and melliferous fields to encourage the work of bees.

Key figures
  • 0 use of pesticides for the upkeep of public gardens and parkland since 2008
  • 6 categories of differentiated management, each with their own upkeep profiles, tailored to each site and its specific purpose
