European or common silver fir (Silba 1986), abeto (Spanish).
Syn. A. pardei Gaussen (Silba 1986).
Trees up to 55 m tall and 260 cm DBH, with a long clear bole and a pyramidal crown that becomes flat-topped with age. Bark smooth, gray, scaly, with resin blisters. Twigs grooved, pale brown or dull gray with a blackish pubescence. Shade foliage 2-ranked, spreading horizontally; foliage in sun more or less erect. Needle base twisted, apex notched or rounded; 15-30 × 1.5-2 mm; upper surface dark shiny green and grooved, usually lacking stomata; lower surface glaucous to whitish-green, keeled, with stomata in 5-8 ranks. Buds pale brown to reddish-brown, ovoid with an obtuse apex, sometimes resinous, diameter 8-11 mm, slightly pubescent. Pollen cones blue/violet/red, 1-3 cm long. Seed cones cylindrical, attenuate at the ends, 10-16 × 3-5 cm, green when young, turning red-brown; cone scales spathulate, finely pubescent with exserted, reflexed bracts extending about 2/3 the length of the scale. Seeds obovoid, reddish, winged, up to 2.5 cm long (Silba 1986).
France; Italy; Switzerland; Germany; Austria; Bulgaria; Ukraine: Karpaty Mts.; Byelorussia; at 300-1950 m elevation (Silba 1986, Vladimir Dinets e-mail 1998.01.02); Croatia. Hardy to Zone 4 (cold hardiness limit between -34.3°C and -28.9°C) (Bannister and Neuner 2001).
Currently the largest known living single-stem tree is the "Great Fir of the Waldhaus" in Germany, with an estimated wood volume of 50 m3, 219 cm DBH, and height estimated at 53.3-54.3 m, based on 2013 measurements (Monumental Trees 2013). A somewhat larger multiple-tree fusion stem is known from Scotland, and there is a larger historic (but well documented) record from Italy. The tallest living tree that has been measured by laser or tape drop is height 56.1 m, DBH 129.5 cm, in Dobroč National Nature Reserve, Slovakia (Räsänen 2015). This also the tallest known tree in Slovakia.
Here are some other reported large trees:
A tree-ring chronology covering 411 years, presumably based on living tree material, was collected in 1952 in Bayerischer Wald, Germany (48.75°N, 13.00°E) by B. Becker (Data accessed at the NOAA Paleoclimatology Program Tree-Ring Data Search Page, 1999.02.24. URL: http://julius.ngdc.noaa.gov/paleo/ftp-treering.html).
Rolland (1993) did an exploratory study; the Bibliography of Dendrochronology provides some 290 additional citations (as of 2006), dating back to 1842, which is interesting (because dendrochronology was officially invented in about 1905)—unfortunately, there are none in English until 1956.
Foliar loppings of European silver fir in Czechoslovakia have yielded 1,380 tonnes/year of essential oils (Cermak and Penka 1979).
Räsänen (2015) describes the Dobroč National Nature Reserve in central Slovakia, saying "Slovakia is known for its numerous prime old-growth forest remnants. ... The preservation of Slovakian old-growth remnants results from their difficult accessibility, the late settlement of the mountainous landscape and the late industrialization of the country. The beginning of the industrial-scale use of the forest and the building of the road net coincided with the creation of the first reserves, i.e. in the late 1800s when there were still thousands of square kilometres of old-growth in Slovakia. ... Recently I made a trip to explore a few Slovakian old-growth reserves. One of them was Dobročský prales = Dobroč Primeval Forest or Dobroč National Nature Reserve in central Slovakia. The reserve is located on a north-facing slope at elevations 720–1000 m. Annual precipitation is 890–960 mm and average annual temperature 4.5–5°C. The reserve was established as early as 1912. The area was originally 50 ha (124 ac) and was later enlarged to 102 ha (252 ac). The original reserve is dominated by European beech [Fagus sylvatica] and European silver fir (Abies alba), and the newer part by Norway spruce [Picea abies]." The photos show a spectacular landscape.
Genetic, pollen and macrofossil evidence shows that Abies alba spent the last glacial maximum in at least three central European refugia: one in the northern Apennines, one in the southern Balkans, and one in the northern or western Balkans. The genetic data also indicate that a similar pattern likely occurred earlier in the Quaternary, with multiple episodes of genetic isolation and introgression (Lipelt et al. 2009).
