Siechastuda – Jenins For a long time, Siechastuda has served as a refuge. Until around 1700, lepers lived here in a plague house, separated from the other villagers. Today, plants and animals that depend on wetlands seek refuge here, as these are now scarce in the intensively farmed Rhine Valley of Graubünden. But it's not just water-loving creatures like the beaver that feel at home in this protected habitat of national importance. Well over 200 plant species, butterflies, bats, hedgehogs, martens, snakes, deer, and many other animals appreciate this near-natural island in the agricultural area. Deadwood is an important component of a naturally developed forest. Standing and fallen deadwood in various stages of decomposition and diameter classes provides a vital habitat for a vast number of creatures. Around 6,000 animal, fungal, and lichen species found in Swiss forests depend on deadwood. Many of these are on the Red List because their habitat has shrunk considerably due to a lack of naturally aged forests with decay phases. According to the guidelines of the Canton of Graubünden and the Federal Office for the Environment, 2-3 deadwood islands should be maintained for every 100 hectares of forest area.
