Information on Ecosystem improved biodiversity:
In the absence of flooding in the 2 years after establishment of the meadow, it is mostly mesophilic grassland which developed. Even in detention ponds that were somewhat flooded in winter, there was no vegetation associated with wetlands.
Monitoring shows the evolution of plant communities towards natural grassland species. Ryegrass dominated regrowth in 2014, before declining sharply the following year to make way for natural grassland species. As at Spring 2018, the floristic composition is thus close to a natural meadow.
The flora that has developed is mesophilic, even in the detention ponds. This may be due to relatively dry years after planting, particularly 2016 and 2017.
