Black Pine (Pinus nigra)

Occurrence in Děčín The oldest specimens grow in the Kvádrberk Arboretum and belong to the subspecies of the Crimean pine. Younger individuals are found in Libverda BZ, cemeteries and many other parks and gardens.  
Application In orcharding and landscaping it is highly appreciated with its versatile use both in groups and solitaire. It tolerates the urban environment well, it is resistant to exhalates. Due to its origin it is more demanding on heat, but in our conditions it freezes rather rarely. It has also often been planted in forests, but unlike the whiteworm, it does not infuse its surroundings.    
Habitat

Occurs naturally in dry and rocky positions on limestone bedrock. However, it is also tolerant of other types of soils except extremely acidic.

Location Occurs in several subspecies occurring in central to southern Europe, the Pyrenees, Italy, Dalmatia, the Crimea and the northern outskirts of Africa.
Wood

It has hard but for a number of knots less quality than a pine forest.

Fruits

Cones: ovate, almost sessile, after 2-4, 4-10cm long, almost symmetrical, yellowish brown, dark brown in color, shiny, scales flat to heavily transverse with short thorn on navel (varies with subspecies). Cones are the most reliable cognitive feature.

       
Blossom Male grow on last year's shoots, dense cylindrical gullies, pale yellow; females grow on shoots, they are spherical and reddish.                 
Leaves Needles: in bundles of two, 8-18cm long, 1-2mm wide, stiff, straight or curved, sometimes twisted, pointed, edge slightly serrated, dark green, with streaks on both sides. They persist 4-8 years, scabbard needles 1-2mm long, dark gray, hardy.         
Branches The young shoots are yellow-green to yellow-brown, more rarely turning orange or red, shiny and glabrous.
Rind

Bark in old trees thick, dark gray to black-gray, longitudinally furrowed with ocher-pink plates.

Treetop

30-40 (50) m tall tree with crown initially conical, later loosened and flattened, branches rising. Old trees can reach trunk strength up to 2m.

Note

Black pine has always been part of the castle gardens and parks. It can also be found in fields, for example, in Záluží near Roudnice, where the largest tree of the species in Northern Bohemia (about 370cm) grows. Beautiful specimens will be seen in the Králova koruna ZP in Chlumec n.C., in Nové Město n.M., in Mnichovo Hradiště and elsewhere. Perhaps the strongest and most interesting will be the individual from the chateau park in Velké Opatovice, with the obv. at ground 600cm, height 32m, low set crown and seven equally strong trunks. By the way, a similar specimen is also growing at BZ University in Oxford. According to monumentaltrees.com, the most massive tree species in Europe is the Vöstenhof in Austria, with a trunk diameter of 730 cm, at a height of 19.5 m.
