Salix mielichhoferi | |
Salix mielichhoferi is a plant from the genus of willow (Salix). It occurs in the montane and subalpine altitudes in the crystalline central Alps of Italy and Austria.
The Tauern willow is an upright shrub with a broad canopy and reaches heights of 1 to 4 m (3 ft 3 in to 13 ft 1 in). The bark of the branches is bare and shiny.
The leaves are divided into a petiole and a leaf blade. The petiole is 5 to 10 millimeters long and has no glands on top. The leaf blade is elliptic to oblong-elliptical to wide-inverted-eilanzettlich at a length of 3 to 10 cm. It is green on both sides. When dried they are mostly black spots. The leaves are not frosted, they can only be indistinctly frosted on long shoots. The leaf veins protrude from the bare and shiny underside of the leaf. [1]
Flowering occurs between May and July before the leaves unfold. [2]
In the Salix genus, the basic chromosome number is x = 19. The Tauern willow is mostly hexaploid and the chromosome number is usually 2n = 114. For Italian populations there are also reports for 2n = 152. [2]
The Tauern willow occurs only in Italy and Austria. [3]
In Austria it occurs in the federal states of Upper Austria, Styria, Carinthia, Salzburg and Tyrol. The focus of the Austrian occurrence is in the Central Alps . The localities range from the Stubai Alps on the Tux and Zillertal Alps, the High and Low Tauern including Defereggengebirge, Kreuzeckgruppe, Nock, Koralpe, Saualpe and Seetal Alps to Stubalpe and the Seckau Alps. There are individual deposits in the northern Alps, for example on the Rofan, Hochkönig and Dachstein . In the Austrian Southern Alps, the Tauern willow occurs on the western edge of the Carnic Alps and in the Gailtal Alps. [2]
In Styria [4] and in Carinthia, the Tauern willow is completely protected, in Salzburg and Tyrol it is partially protected. [2]
In Italy, the Tauern willow was found in the five provinces of Bozen (South Tyrol), Trento, Brescia, Belluno and Udine . Information from Switzerland for the Lower Engadine could not be confirmed. [2]
The Tauern willow occurs in the montane to subalpine altitude range, in Austria at altitudes from 1300 to 2200 meters. The focus is on the subalpine level. There are also individual occurrences outside this altitude range, for example at Kals at 1250 meters and at the Großglockner High Alpine Road at 2300 meters. The main occurrences are in the green alder bush forest, in high-montane to subalpine willow bushes over silicate in alluvions and riverside pioneer locations of rivers. [2]
Tauerngasleitung willow (Salix mielichhoferi) is connected to the black willow (Salix myrsinifolia) and is together with the latter in a Salix nigricans - aggregate provided. [1]
Salix mielichhoferi was named by its first describer Anton Sauter after the Salzburg botanist Matthias Mielichhofer, who was the first to collect this species. The Locus classicus is the now dilapidated Schappachalm, southwest of Hüttschlag at around 1580 m above sea level, in the Ankogel group, Hohe Tauern, Salzburg. [2]
Austria is a predominantly mountainous country in Central Europe, approximately between Germany, Italy and Hungary. It has a total area of 83,871 square kilometres (32,383 sq mi), about 2.031706 times the size of Switzerland.
Tourism in Austria forms an important part of the country's economy, accounting for almost 9% of the Austrian gross domestic product. Austria has one guest bed for every six inhabitants, and boasts the highest per capita income from tourism in the Organisation for Economic Co-operation and Development. As of 2007, the total number of tourist overnight stays is roughly the same for summer and winter season, with peaks in February and July/August.
The High Tauern are a mountain range on the main chain of the Central Eastern Alps, comprising the highest peaks east of the Brenner Pass. The crest forms the southern border of the Austrian states of Salzburg, Carinthia and East Tyrol, with a small part in the southwest belongs to the Italian province of South Tyrol. The range includes Austria's highest mountain, the Grossglockner at 3,798 metres (12,461 ft) above the Adriatic.

Eastern Alps is the name given to the eastern half of the Alps, usually defined as the area east of a line from Lake Constance and the Alpine Rhine valley up to the Splügen Pass at the Alpine divide and down the Liro River to Lake Como in the south. The peaks and mountain passes are lower than the Western Alps, while the range itself is broader and less arched.
The Radstadt Tauern are a subrange of the Central Eastern Alps in Austria. Together with the Schladming Tauern, the Rottenmann and Wölz Tauern and the Seckau Tauern the Radstadt Tauern form the major range of mountains known as the Low Tauern. The mountains are found in the southeast of the Austrian state of Salzburg, between the upper reaches of the Enns and Mur rivers.
