The site

The Regional Nature Reserve of Crêt des Roches, Pont-de-Roide, Doubs (25) is a departemental migration hotspot but also an important breeding site in Franche-Comté. This is why the site is both interesting for observation and for a migration watch.

The surroundings and natural setting of the site

Crêt des Roches is occupying 40 hectares on the heights of Pont-de-Roide. The limestone cliff benefits from a microclimate allowing a great variety of mediterranean and alpine plants to grow thanks to a particular exposition at this latitude. Since 2000, the site has been designated as the Regional Nature Reserve of Crêt des Roches. It is presenting a mosaic of original xerophilous habitats: pastures, scree, Pubescent Oak forests of regional interest, thermophilous beech forests. The presence of many relict plants is noteworthy, such as Candytuft Iberis intermedia, Perennial Candytuft Iberis saxatilis - the only place it is growing in Franche-Comté -and Alpine Daphne Daphne alpina. The uniqueness of this natural heritage has motivated its inclusion in the European Natura 2000 network.

History of the survey

A migration survey at Crêt des Roches takes place annually since 1987 between 15 September and 15 November (at least during weekends). Since 2008, the volunteers birdwatchers of the LPO count every day (august to november) the migrators.

Ornithological interest, emblematic species

An important par of the western European avifauna is following the Rhine migration corridor, avoiding the Vosgean Massif and bumping into the foothills of the Jura mountains, taking advantage of thermals and dynamic air currants created by the mountains.
On a north-south axis, birds are following the jurassic arc in a northeastn/southwestern direction.
La Cluse (from Latin clusa = closed; narrow deep gorge eroded perpendicularly in a mountain chain; typical jurassic term) of Pont de Roide is situated in the middle of such an axis and this is a privileged position for the autumn migration of birds.

About one hundred bird species have been noted.
