Conservation status

Picea abies

(Linnaeus) Karsten 1881

Common names

Norway spruce, epicéa commun (French French) (Farjon 1990), épinette de Norvège (Canadian French) (Taylor 1993), gemeine fichte (German), jel europeiskaya (Russian) (Farjon 1990).

Taxonomic notes

Synonymy:

Numerous varietal and subspecific names have been published, but few are sufficiently distinct to be worth recognising. The most widely recognised is var. acuminata (Beck) Dallimore & Jackson from the SE of the range in the Balkan Peninsula (Farjon 1990).

A large area of hybrid introgression with P. obovata has developed since the two species met after the last Ice Age between the Ural Mts and Finland, treated as Picea × fennica (Regel) Komarov (Farjon 1990). Some authors treat P. obovata as a subspecies or variety of P. abies.

Its closest relationship is probably with the P. asperata complex of China, which are often similar in cone morphology and foliage (Frankis 1992).

The species Picea alpestris Bruegger ex Stein is commonly treated as a variety, P. abies var. alpestris (Bruegger) P. Schmidt (Farjon 1990), but is distinct in morphology and probably more closely related to P. obovata and other allied Asiatic species (Frankis 1992).

Description

Trees to 40–50 m tall and 100–150 cm dbh; crown conic. Bark orange-brown, finely flaking, becoming gray-brown, scaly on old trees. Branches short and stout, the upper level or ascending, the lower drooping; twigs orange-brown, usually glabrous. Buds reddish brown, 5–7 mm, apex acute. Leaves 1–2.5 cm, 4-angled in cross section, rigid, light to dark green, bearing stomata on all surfaces, apex blunt-tipped. Seed cones (10–)12–16 cm; scales diamond-shaped, widest near middle, 18–30 × 15–20 mm, stiff, leathery, margin at apex erose to toothed, apex extending 6-10 mm beyond seed-wing impression. 2 n =24 (Taylor 1993, M.P. Frankis, pers. obs. 1999.01.06).

Var. acuminata is distinguished by longer-than-average cones (to 18 cm, the longest of any spruce) with more acute cone scales (Farjon 1990).

Hybrids with P. obovata (P. × fennica) and P. alpestris show pubescent shoots and cones with more rounded scales (M.P. Frankis, pers. obs. 1999.01.06).

Distribution and Ecology

Native to N, C & E Europe outside permafrost areas south to N Greece and W to the Massif Central, France; south of 47° N latitude only in mountains above 400–500 m; ascends to 2200 m in the Balkans (Vidakovic 1991). This area includes: Albania, Austria, Belarus, Bosnia & Herzegovina, Bulgaria, Croatia, Czech Republic, Estonia, Finland, France, Germany, Greece, Hungary, Italy, Latvia, Lithuania, Macedonia, Montenegro, Norway, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, Sweden, Switzerland, and Ukraine.

In the NE portion of its range, there is a broad zone of hybridisation with P. obovata (Silba 1986, Vladimir Dinets e-mail 1998.01.02).

Locally naturalized in Europe out of its native range including Britain and the Pyrenees Mts., and in the north-central United States (and adjacent Canada) (Taylor 1993). Hardy to Zone 4 (cold hardiness limit between -34.3°C and -28.9°C) (Bannister and Neuner 2001); var. acuminata, Zone 6).

Big tree

Within most of the species' range, 100 cm dbh is quite a large specimen, partly because of the general rarity of old trees; outside of the northern forests, old forest is quite rare in Europe. The largest specimen of which I have received report is 214 cm dbh (1.3 m above ground), albeit tapering rapidly above that height (160 cm at 2.2 m), and is 56.2 m tall. The height of this tree is not recorded. It grows in the forest of Biogradska Gora National Park, Montenegro (full report and photographs: Räsänen 2008 and email, 2013.02.25). Mr. Räsänen (email 2010.12.25) states that "P. abies of 100 cm dbh are common in the old-growth remnants of the mountains of southern and central Europe. Picea abies and Abies alba are usually the largest trees, the former often having larger dbh, but the latter having larger volume due to slower stem taper." There is also record of a tree 153 cm dbh and 45 m tall from the Bagni di Mezzo, Trentino Alto, San Pancrazi, BZ, Italy (Corpo Forestale della Stato, a listing of big trees in Italy). The largest cultivated tree of which I have record is 147 cm dbh at Lingholm, Cumbria, UK (Mitchell et al. 1990).

The tallest specimen that has been reported using accurate measurement technique (tape drop or laser survey) is 62.26 m tall (above mid-slope) and 115 cm dbh (above top-slope). It is the Sgerm Spruce (Sgermova smreka) in Ribnica na Pohorju, west of Maribor, Slovenia, on private land Cthe Sgerm farm). It is estimated to be 250 years old, based on a ring count of a fallen nearby tree of similar size, and has been measured repeatedly using professional methods (including theodolite, laser, and direct tape drop); it was 51 m in 1938, 57.5 m in 1980, and 61.7 m in 1995 (Räsänen 2012). The second-tallest specimen is 59.2 m tall. This well-known tree is in Sächsische Schweiz National Park, Germany. The same park contains a number of other trees measured at over 50 m tall (Räsänen 2010).

Oldest

Tree LBG in the Bavarian Forest of Germany had a crossdated age of 468 years. It was collected by R. Wilson (RMTRR 2006).

Dendrochronology

Ethnobotany

A timber tree of major economic importance throughout the cool temperate areas of Europe. The commonest tree used for Christmas trees in Britain, despite its poor suitability for this purpose, with the leaves soon shed as it dries out. A herbal tea can be made from the leafy twigs and is reputed to have various curative powers, not tested medicinally.

Observations

Remarks

This is the most widely used horticultural spruce in North America; many cultivars exist, including dwarf shrubs (Taylor 1993).

Picea abies is the most climatically tolerant species in the genus, happy in cultivation in both extreme oceanic NW Scotland and central continental Wisconsin. This might be a legacy of adaptation to rapidly fluctuating climates in Europe during the Ice Ages (and now, for that matter).
