Stelvio National Park occupies 130,734 hectares across the central-eastern Alps, distributed between the regions of Lombardy and Trentino-Alto Adige/Südtirol. Established in 1935, it ranks as Italy's fourth-largest national park by surface area and the largest alpine park in the entire country. Its boundaries encompass 24 municipalities and an elevation range stretching from roughly 650–690 metres in the lower Adda valley floors to 3,905 metres at the summit of the Ortler massif.
Habitat Distribution by Zone
The park's terrain is divided into four broad habitat categories as recorded in the European Nature Information System (EUNIS) database:
- Shrubland (30%) — dwarf shrub heath and subalpine scrub, particularly Pinus mugo formations and Rhododendron ferrugineum stands between 1,600 and 2,200 m.
- Forest (26%) — dominated by Norway spruce (Picea abies) in the montane belt, with Swiss stone pine (Pinus cembra) forming near-treeline woodland above 1,800 m.
- Rocky areas (25%) — bare rock faces, scree fields, and glacier surfaces. The Ortler-Cevedale massif contains the largest glaciated area within any Italian national park.
- Alpine grassland (<10%) — calcareous and siliceous pastures above 2,200 m. These support the highest densities of breeding raptors and gamebirds in the park.
- Wetlands and water bodies (<5%) — glacial lakes, mires, and stream corridors fed by seasonal snowmelt.
85.17% of Stelvio's total area falls within an internationally recognised Key Biodiversity Area, according to the KBA Factsheet 2732.
Transboundary Conservation Block
Stelvio does not function as an isolated reserve. Its western and northern boundaries are contiguous with the Swiss National Park (Engadine), Adamello Brenta Natural Park to the east, and Adamello Regional Park to the south. Together, these adjacent protected areas form a continuous block of approximately 400,000 hectares — one of the largest unfragmented protected landscapes in the Alps. Wildlife corridors along this block are ecologically significant for large carnivores including brown bear (Ursus arctos), which periodically disperses from the Adamello population into Stelvio.
Governance: Three Administrative Bodies
The park is managed under a structure unusual for Italian national parks: governance is shared between three separate public bodies corresponding to the autonomous regions and provinces of Trentino, Südtirol (Alto Adige), and Lombardy. This arrangement, established after a 2008 reform, means that operational decisions on trail management, visitor regulation, and species monitoring are taken at the provincial level rather than by a single unified park authority. The Italian Ministry of Environment (MASE) retains oversight and receives annual reporting from all three bodies.
Historical management reviews identified several persistent structural challenges: progressive abandonment of mountain pastures has altered subalpine shrub distribution; increasing tourist resort infrastructure around Bormio and Passo dello Stelvio generates edge effects on adjacent wildlife habitat; and coordination across three bodies with different legislative frameworks has periodically delayed cross-boundary monitoring protocols.
Key Species and Conservation Significance
The park is classified as a Key Biodiversity Area for its importance to Eurasian high-montane bird communities. Recorded breeding species include golden eagle (Aquila chrysaetos), bearded vulture (Gypaetus barbatus), black grouse (Lyrurus tetrix), and rock ptarmigan (Lagopus muta). Mammal records include Alpine chamois (Rupicapra rupicapra), red deer (Cervus elaphus), roe deer, and small populations of Eurasian lynx. In December 2025, approximately 20,000 dinosaur trace fossils dating to the Triassic (approximately 210 million years BP) were identified within the park's geological formations — one of the largest such assemblages known in Europe.
Plant diversity at the rocky zone level includes the endemic Campanula raineri, a flowering campanula restricted to calcareous rock outcrops in the Stelvio and Swiss National Park region.
Visitor Management Framework
Visitor access is structured through a permit system at designated high-altitude zones, particularly around the Stelvio Pass road (Passo dello Stelvio, 2,757 m) — one of the highest paved mountain passes in the Alps. Seasonal traffic restrictions apply from October to May due to snow closure. The park operates visitor reception points at Bormio, Prad, and Cogolo di Peio. No formal carrying-capacity caps have been published for the park as a whole, though the BirdLife Datazone notes that tourist resort development constitutes an ongoing management concern.
