Biosfera Val Müstair, Switzerland


Biosfera Val Müstair lies in southeastern Switzerland, along the country’s border with Italy. The biosphere spans 199 sq. km (77 sq. miles) and is home to around 1,400 people.

The nature reserve is located within a mountainous valley near Furon Pass. The rugged Alps tower above on either side of the valley. Lower elevations in the reserve are full of lush green meadows and small towns, interspersed with densely forested patches.

The Rom River, a tributary of the Adige, runs through the valley passing through many of the region’s villages. The well maintained landscape of the nature reserve provides a sharp contrast to nearby untamed and wild terrain of Swiss National Park.

A majority of the foothills in the park are covered by dense patches of forest, which lead up into the alpine terrain. Jagged snow-capped peaks define the skyline of mountains that tower high above the treeline. Meanwhile, many of the cleared fields at the floor of the valley are used for farming purposes.

Biosfera Val Müstair is full of a variety of landscapes, including areas of developed land that contrast startly with the wild terrain that towers high above the valley. Approximately 55 percent of the region is covered by mountains, rivers, and glaciers.

The Engadine Valley lies within the reserve and the Inn River (En River) that flows through it is the only river in the country that drains into the Danube River.

The reserve, along with the adjacent ​​Swiss National Park, was the first UNESCO high alpine biosphere reserve in the country. Biosfera Val Müstair is also home to the Convent of St. John UNESCO World Heritage Site and the Manufactura Tessanda weaving mill.

Additionally, Biosfera Val Müstair is located near a number of major protected parks in the region. Swiss National Park lies directly west along with Parc Ela and Beverin Nature Park. Binntal Nature Park is located to the southwest of the reserve while Stelvio National Park in Italy is situated to the south and east of the reserve.


The peaks surrounding the valley are part of the Sesvenna Alps and Ortler Alps. The Sesvenna Alps extend into northern Italy and western Austria while the Ortler Alps span into Italy.

The two ranges are separated by Ofen Pass, which lies within Val Müstair. Together these two ranges cover land across both the Central Eastern Alps and the Southern Limestone Alps.

These peaks, along with the rest of the Alps, began forming around 65 million years ago. The Alpine orogeny was a mountain building period that formed the Alps as well as the Pyrenees, Himalaya, Karakoram, Caucus, Atlas, Carpathians, and the Hindu Kush.

To the southwest of the range, in between present day Africa and Europe, once lay the Tethys Ocean. As the tectonic plates that surrounded the Tethys began to move toward one another, the ocean began to shrink, leaving behind only the sediment from the ocean floor.

As the two plates collided with one another, recumbent folds caused by the extreme pressure began forming the Alps. What was once the seafloor was transformed into a rugged mountain range over the course of millions of years.

The peaks within Biosfera Val Müstair consist of limestone and sandstone, two easily erodible rocks that over time have given the range its jagged appearance.

A majority of the Alps were heavily glaciated during the last glacial maximum. Following this period, glacial retreat carved out the various valleys and peaks even further, leaving behind the sweeping valley found within the biosphere reserve today.

Major peaks within Biosfera Val Müstair include Piz Murtaröl, Piz Tavrü, Piz Daint, Piz Turettas, and Cima del Serraglio.


Despite the development throughout the region, Biosfera Val Müstair is home to a variety of both flora and fauna. The cleared off valley floor is primarily used for farming purposes, with over 80 percent of the valley implementing organic farming practices.

The forested foothills in the reserve contain dense patches of mountain pine, larch, and Norway spruce. At higher elevations, hikers can spot scree fields along with fields of alpine grasses.

Higher elevations in the biosphere are also home to a variety of wildflowers. Common species include Swiss androsace, vanilla orchid, alpine aster, edelweiss, fairy thimble bellflower, among various others.

Large populations of animals are not as common in Biosfera Val Müstair as in nearby Swiss National Park. Animals who enter the region often stay in the forested hillsides or above the treeline to avoid the various villages.

Common animal species in the region include chamois, red deer, ibex, marmot, mountain hare, fox, lynx, and the occasional brown bear. The bearded vulture, golden eagle, and ptarmigan are all bird species that you can see in the reserve, too.

Human History

Humans have inhabited the Val Müstair region for thousands of years. The alpine valleys are thought to have been originally settled by the Raetains around 3500 BCE.

The land in the biosphere, along with much of present day Grisons, was once part of the Roman province known as Raetia. This province was established around 15 BCE.

After the fall of the Roman Empire, humans continued to inhabit the region and establish larger settlements. The Abbey of Saint John, which lies within Biosfera Val Müstair, was established in 780 CE. It is believed the abbey was built by a Bishop of Chur, during a wave of monastery construction.

Situated along Val Müstair, the abbey marked the pass over the Alps into present day Italy. The abbey was later expanded and painted during the eleventh and twelfth centuries CE.

The modern canton of Grisons began to form during the fifteenth century when the Three Leagues (Raetia) alliance further allied with the Old Swiss Confederacy. After the Habsburgs were defeated at Calven Gorge and Dornach, the canton and the Old Swiss Confederacy began gaining international recognition.

The region came under Napoleon rule in 1794 as part of the Helvetic Republic. In 1814 the region was part of the Empire of Austria before it became part of the Kingdom of Italy in 1859. Eventually the region became part of Switzerland. The constitution of Grisons dates back to 1892.

Biosfera Val Müstair became a UNESCO Biosphere in 2010. It was designated as a Nature Park in 2011.
