At the edge of this road a pond which forms with the forest which surrounds it a protected natural area. Each year, during the thaw (roughly from February to April), a "toadstool" is installed on the road that runs along the pond. But what is a toaddrome exactly? So, it is not a place where one could indulge in clandestine bets on toad races, but a device intended to prevent these poor beasts from being crushed by cars in crossing the road to breed and lay their eggs in the pond on the other side of the road. Indeed, thousands of common toads, but also frogs and newts, begin their long prenuptial migrations around March each year. They go to the nearest pond or pond to breed. Once their duty is done, they leave the aquatic environment to return to their summering areas where they will spend most of their time feeding. In order to avoid a carnage of amphibians on the road, a tarpaulin is planted 600m on each side of the road to block their passage. In various places a hole has been made in which a bucket is buried. By looking for a passage all along the tarpaulin, the toad will inevitably end up at the bottom of a bucket. Every morning, volunteers come to collect toads and other frogs and drop them off on the other side of the road.

Located at an altitude of 154 meters1, the pond covers an area of 0.8 hectares. The “Ponts-Quentin stream” flows into the Rompu pond — coming from the Holland ponds located about 1 km upstream to the east — and comes out to flow, about ten kilometers further to the west, in the Vesgre, having previously changed its name twice: first under the name of “Etang-Neuf stream” then under that of “Grapelin”. The Ponts-Quentin stream passes under departmental road 138 before flowing into the pond, which justifies the undulation of the road and its bend. The pond is part of the Rambouillet national forest, a private state domain. As such, its management is ensured by the National Forestry Office (ONF). Wikipedia
