Description
The Inn wetlands near Bever are an ambitious renaturation project that began in 2012. Over a stretch of about 2 kilometers, the river flows in a natural bed up to 90 meters wide, characterized by eroded banks, alluvial forest, and gravel banks. What makes it special is the elevation: the Inn runs through a wide valley floor here at 1,700 meters above sea level and is surrounded by high mountains.
The area consists of two wet meadows (1 and 2), alluvial forest developing along the new inner waters (3, accessible) and on the other side of the river (4, inaccessible), and the Inn itself, which is allowed to follow its natural dynamics from the point where the Beverin joins it (5). From an ornithological perspective, the area is especially interesting in April and early May during spring migration, particularly when bad weather occurs in the Alps. Then, bird migration may stall in the Inn valley (similar to the Bolle di Magadino in the Ticino), and rare species use the meadows, bushes, and waters to rest. This is why the number of bird species observed here is astonishingly high for a montane location - over 210. Chevalier sylvain, Balbuzard pêcheur, Chevalier aboyeur, Vanneau huppé, Sarcelle d'été, Canard siffleur, Bihoreau gris, and Chevalier culblanc are among the more frequently seen special species. Numerous rarities have also been documented with one or two sightings, such as Guifette moustac, Oedicnème criard, Chevalier arlequin, Échasse blanche, Fauvette mélanocéphale, Étourneau roselin, and Crabier chevelu.
Later in the year, one can also observe interesting breeding birds. Central to conservation efforts are the gravel banks, which are valuable breeding sites for Chevalier guignette and Petit Gravelot. Twenty percent of Switzerland’s Chevalier guignette population breeds here. Also noteworthy is the Fuligule morillon. The Gravatscha Lake (6) is one of the few places in Switzerland where it regularly raises chicks. The Grèbe castagneux can also be seen on the lake. It is common in Switzerland but rare in the Grisons and mountainous regions. In the alluvial forest and open pine woods at the edge of the area, the Sizerin cabaret can be found, and the call of the Cassenoix moucheté is regularly heard. The Tarier des prés breeds in the meadows, having retreated from intensively farmed lowlands into the mountains. Other breeding birds in the area include Fauvette babillarde, Torcol fourmilier, and Pie-grièche écorcheur. Until a few years ago, Caille des blés breeding was also recorded. Numerous sightings of Bécassine des marais have been documented. It’s also worth occasionally looking up: Gypaète barbu and Aigle royal are sometimes seen soaring over the valley.

Beavers and otters have returned to the renatured river. Before the renaturation, the European adder - the only snake species in the Upper Engadine - lived in the cracks of the dikes; they were later relocated to the new dikes.
