Chamrousse sheeps

Goats and sheeps

The shepherd is in Chamrousse from middle-june to the end of September with its 1600 sheeps and 35 goats. More than ten heifers grazed in the sheep pen of Chamrousse 1650. The transhumance festivities is an event from the beginning of July that permits to discover this herd.
 

Amphibians

In wetland of Chamrousse (Achard lake, Arselle peatlands, Roberts lakes, etc…) it is possible to see different species of amphibians:

- The Palmate newt is in Chamrousse, in his high limit known in the department because it goes until 1650m in le Recoin. Also ubiquitous, it can be seen in diverses areas. It shares its habitat with the Alpine newt. These two newt are suffering about the lack of wetlands. The conservation of their breeding habitat (peat trenches, small lakes, spawning and shaded rivers) is important to maintain their populations.

- The Brown frog is a ubiquitous specie found in the heterogeneous habitats (forests, bocages, paths). In altitude, it is generally around water sources, just a few vegetalised or in peat lands. It avoids areas where there is too much water. In the region, this species is living in most of the mountain chains until 2 500 meters high (record in the Savoy department, at 2905 meters). The Brown frog is suffering about the loss of its habitat.

- Furthermore, it is possible to ear or to see a common toad.
