Phyto-remediation involves using certain plants, trees and shrubs to clean up the environment.

Three phyto-remediation gardens are being created at the park. While the decision to create gardens that will restore the environment is in line with the sustainable development plan, it is also an innovative approach. Phyto-remediation relies on the use of functional eco-systems to purify the environment.

Two phyto-remediation techniques are used at the park:

• Phyto-extraction: the pollutants are trapped by the roots and transferred into the foliar system. The shoots are then mowed or cut to remove pollutants from the plants. Hyperaccumulators (willow, genet, heather, etc.) are used for phyto-extraction.
• Phyto-stabilisation: Pollutants are trapped and kept in the root system. This technique is used to make environments less toxic while stabilising certain types of environment (hills, rivers, etc.).
