Biotopo Torbiera di Rasun, Regional nature reserve in Rasen-Antholz, Italy

The Biotopo Torbiera di Rasun is a regional nature reserve featuring marshy meadows, small lakes, and dense forests spread across roughly 23 hectares at 1,075 meters (3,530 feet) elevation. The terrain shows distinct zones where water and vegetation define the landscape character.

The biotope was established in 1975, not 1973, and covers 24.92 hectares in the municipality of Rasen-Antholz in the autonomous province of Bolzano. It lies within the Vedrette di Ries-Aurina Nature Park, which gives the moorland additional protection. The orchid Malaxis paludosa, critically endangered locally, has its only Italian station here.

The reserve lies in the municipality of Rasen-Antholz (Rasun Anterselva), whose Italian and German names both appear on local signage and on the reserve's own name, Biotopo Torbiera di Rasun in Italian and Feuchtbiotop Rasen or Rasner Möser in German. The moor itself is known in German as Rasner Möser, "the Rasen bogs".

You can reach the reserve via a roughly 20-minute walk starting from Oberrasen church, following wooden walkways with informational panels along the route. The path is straightforward and offers opportunities to spot wildlife as you move through the space.

The bog hosts Italy's only known station of the orchid Malaxis paludosa, a species assessed as critically endangered at local level. The site lies within the Vedrette di Ries-Aurina Natural Park and covers 24.92 hectares in the municipality of Rasen-Antholz.
