European silver fir is a long-lived conifer and the largest tree (up to 60 m) of the native Abies in Europe. It is not native to Britain but was an early introduction in 1603. Although widely planted as a specimen tree it has only been used on a small scale as a forestry species. Poor uptake was because early trials indicated susceptibility to silver fir wooly aphid; however, a recent reassessment of the species indicated it can be a productive species in Britain. There is growing recognition it has a place in forest diversification and is consequently being more widely used.
Abies alba is categorised as a Secondary tree species. These are a group that have demonstrated positive silvicultural characteristics in trial plots but gaps in knowledge constrain wider use. The species are being actively evaluated to increase understanding and inform future deployment.
European silver fir growth starts slowly, and trees can take 8-10 years to establish. Subsequent growth can be rapid and make it a high-volume producer with a yield class range from 10 to 22 depending on site.
European silver fir is not suited to planting on open or exposed sites and can be severely damaged by cold and wind. A deep tap root system does make it relatively wind firm when compared with other species like Norway spruce. As a shade-tolerant species sensitive to exposure European silver fir is best suited to planting in sheltered sites as group planting or underplanting.
Under the right conditions European silver fir can produce good quality seed and regenerate well. Shade tolerance can enable natural regeneration to act as a "seedling bank" under the canopy suiting it to continuous cover forestry. Understorey vegetation can be a hindrance to natural regeneration. European silver fir is highly palatable to deer and other browsing mammals.
Cold hardy throughout Britain but vulnerable to frost unless planted under shelter. Sensitive to exposure and is not drought tolerant. Grows well with an annual rainfall from 700 mm but will be most productive where rainfall is >1000 mm evenly distributed across the year.
Suited to soils of poor to medium nutrient status with fresh to moist soil moisture. Can grow on deep soils over limestone and other calcareous substrates. Does not tolerate very poor soils or heather competition and should not be planted on peats or very dry soils.
Provenances from Calabria in southern Italy out-performed other provenances in UK trials and should be the first choice for planting throughout Britain. However, other provenances from across the rest of the natural range of European silver fir also performed well.
