Agreement signed on

the local wild seed network in

the Île-de-France region There is currently a lack of available local wild

seeds in the Île-de-France region. Solutions

must be found to the challenges associated

with native plant species, particularly for

the project: anticipating and developing the

supply of plants in the Île-de-France region

to meet needs; raising awareness and

providing support to companies holding

public procurement contracts with Société

du Grand Paris to ensure that local wild seeds

are used.

In this regard, a partnership agreement was

signed in November 2020 between the

Conservatoire Botanique National du

Bassin Parisien (CBNBP), CDC Biodiversité

and Société du Grand Paris. The purpose of

this agreement is to establish a production

chain for herbaceous seeds adapted to the

Île-de-France region in response to current

climate and environmental issues, which can

be used to revegetate sites after construction

and to restore the Grand Paris Express

ecological offsetting sites. The first concrete

actions under this agreement will start in

2021.

Launch of the environmental

and societal policy for urban and

real estate projects Société du Grand Paris has started to draw up

its environmental and societal policy, which

includes consideration of several actions to

integrate biodiversity into urban and real

estate projects.

These include ensuring ecological continuity

(green, blue, brown and black belts) and

providing ecosystem services. It will be

delivered in 2021.

Prioritising the use of wild and native plants

As part of the planting work carried out on the offsetting sites, the company prioritises the use

of wild and local plants and seeds. In the context of climate change and a high probability of

an increase in extreme weather events (droughts, storms), these plants will have greater

resilience and will help preserve local genetic diversity, suited to the soil or climate. This also

limits the risk of introducing invasive species and helps to make ecosystems more resilient.

Developing biodiversity around stations

Several principles included in the Place du Grand Paris public space planning and design guide

are intended to maintain or develop biodiversity around future stations:

– make the public space around stations an essential link in the green and blue belt networks;

– moderate the intensity of lighting;

– make the water cycle visible (e.g. open-air rainwater management);

– make public spaces feel more like gardens;

– identify, protect and develop the tree heritage;

– install living natural environments (e.g. green roofs);

– plant trees, plant directly in the ground, etc.
