Espace Naturel Sensible de l’étang de Lemps

Having changed little since the 18th century, this site is subject to environmental management and scientific monitoring aimed at preserving the exceptional richness of its natural habitats.

Reedbeds, ponds, wet meadows, dry meadows, hedgerows and limestone hillsides form a mosaic of environments that support remarkable biodiversity. Twelve heritage habitats have been identified, including eutrophic stagnant waters and vast reedbeds, veritable refuges for aquatic fauna.

The flora includes 457 plant species, including 14 heritage species. Throughout the seasons, visitors can observe wild orchids, the Loose-flowered Orchid, the Marsh Orchid, the Water Germander, the Southern Bladderwort, the Common Adder's-tongue Orchid, or the Amellus Aster, testifying to the ecological richness of this wetland.

The wildlife is equally remarkable. The pond is home to 130 bird species, including the Little Bittern, the Kingfisher, the Reed Bunting, and the Reed Warbler, which find in the reedbeds a privileged place to feed, breed, or stop over during their migration. The terrestrial habitats also support numerous amphibians and reptiles, as well as heritage insects such as the Green Damselfly and the Stag Beetle.

A true window onto nature, the bird observatory allows visitors to observe wildlife without disturbing it. Located on the edge of the reedbed, it offers a privileged view of waterfowl and aquatic life throughout the year.
Depending on the season, it is possible to witness migrations, observe nesting species or surprise those that simply come to stop over at the pond.
An educational wheel installed in the observatory helps identify the species present depending on the month of your visit, making each visit a different experience. With a little patience and a pair of binoculars, dragonflies, herons, kingfishers, and many other species reveal themselves to the most observant visitors.

The Lemps Pond can be explored at the pace of an educational trail marked with 9 interpretation stations that explain the functioning of wetlands, water management, the landscapes of Isle-Crémieu as well as the close links between the different natural environments and the species that occupy them.

For a more interactive experience, two orienteering courses are also offered on the site: an adult version and a children's version.
Stretching 3,6 km and comprised of 8 markers, they follow the same route but offer questions tailored to different audiences. An original way to explore the Lemps Pond, observing its natural heritage while taking on a family challenge.
