Etang de But, ENS de l'Ain

The "Etang de But" site has been designated a sensitive natural area (ENS). It belongs to a chain of ponds in the southern Bresse plain, marking the transition to the Dombist plateau.
This artificial pond is remarkable for the species of flora and fauna it contains. Set in a forest setting and sometimes covered with a carpet of white water lilies, it offers a variety of landscapes through the seasons.

Key issues for the site

Fauna: presence of the Leucorrhine dragonfly, yellow-bellied toad, great crested newt, Little Bittern, Black-crowned Night-Heron.

Flora: Royal fern, water scorpion, Bohemian sedge, etc.
The woodlands near the pond have a role to play in the pond's ecological functioning, in addition to their landscape value. Good management of these woodlands is essential.
The main threats are the risk of the pond filling up, and invasion by invasive species.

To discover the site...
An information panel is located at the thou (drainage system), to the west of the pond. The site is generally accessible to pedestrians.

The Etang de But was awarded the ENS or espace naturel sensible label by the Département de l'Ain in 2015. True natural and landscaped jewels of the Ain department, these ENS-labeled sites are on the one hand preserved through local management and on the other made accessible to as many people as possible when the fragility of the site allows.
