 | | The sentry of pure waters, the otter occupies a place of choice the river's ecosystem: seeking diversified food, hides in the river banks and good quality water, its presence is emblematic of a river in good health. |
 | | The river's old beds, supplied with water either by the river itself when it floods, or by the water table, or both, are wet areas that play a predominant role in the life of numerous species: feeding, refuge, reproduction. |
 | | Today, this is the most common environment around the Lower Ain river: the areas abandoned by the river are rapidly colonised by herbaceous vegetation, bush willows, then poplars, which contribute to enriching the soil by trapping fines. |
