The ponds of the Nine Fountains, which date from the mid-19th century, are home to interesting environments, particularly the wetlands located near the banks (sedge grove, willow grove, etc.).
The wetland located in the northwestern part has developed well. On the other hand, the southern bank hosts equally humid vegetation, but on a narrower strip. This vegetation finds a continuity with the mixed afforestation of the hillside composed, among other things, of old oaks, old chestnut trees and old pines, which constitutes a favorable environment for avifauna.
The presence of springs with well-developed aquatic vegetation (Sedges, Ache nodiflora, Pondweed, Duckweed) is potentially interesting for dragonflies and amphibians.
These environments serve as a refuge for a variety of fauna, some of which are emblematic, such as the pond terrapin or the otter.
