Quercus petraea jarni habitus

Winter Oak (Quercus petraea)

Occurrence in Děčín

Large winter oaks can be found in the upper part of the Bažantnice forest park, where the trunk strength reaches up to 1m, the largest of which is 1.20m. The tree you stand by is probably the largest representative of the winter oak on the Shepherd's Wall. It has a circumference of 330cm and a height of 25m.    
Application

In landscaping it is very valuable and widespread, especially in landscape and large urban parks it forms the basis of tree stands. It is planted in groups such as solitaire and alley, as well as for reinforcement of pond dams. It willingly crosses with the summer oak, so especially in the lower altitudes, the forest oak stands are just these hybrids.
Habitat

Grows on rocky, drier soils, forms mixed oak forests from lowlands to submontane zone at altitudes 600-750 m above sea level. It tolerates the urban environment well. It is resistant to frost and exhalates. 
Location Europe except East to Northeast, Asia Minor.

Note Our biggest winter oak was the so-called "Albrechtický dědoušek", which grew in the cadastre of Albrechtice in the vicinity of the chateau park under the Jezeří chateau in the Most region. It was the so-called "border tree", which until then only survived five. At the end of the 19th century. (published in J.E.Chadt-Sevetinsky's publication: "Old and memorable trees in Bohemia, Moravia and Silesia") had 1230 cm in perimeter, and 1000 years old. At that time it was the largest oak not only in our country but also in Central Europe. At the turn of the 19th and 20th centuries, a massive branch broke off with a piece of tree, so a large cavity appeared. It was roofed, and in this form I knew it when I went to school around it in the 1950s. Despite all the adversity, he was still in good health at the beginning of the 1990s, and in 1993, when I visited him, he grew with new shoots. But in the summer of the same year he was repeatedly burned by an "unknown" vandal. Remarkable was the immediate announcement of the mining company of "lighting the oak with lightning" (no storm was observed long before or after the oak firing). People from the wider surroundings of the flower wore the burned oak, a thorn in the eye of the company. By doing so, the tree's torso was disproved by the bulldozer and then completely removed to leave nothing left of it ...
