“…Moreover, the vari-of Sitka spruce, while it attained 79.2% in Czechia and 81.8% in Slovakia. Similar results are documented, for example, by MacDonald (1979). The production potential of Sitka spruce over Norway spruce corresponds to its range of introduction.…”

“…Sitka spruce is not an invasive tree species (Buriánek 2019). Its litterfall is comparable to that of Norway spruce (MacDonald 1979) and its more noticeable introduction in Europe is expected to occur mainly in coastal areas with sufficient precipitation (Moore et al 2012;Worrell & Malcolm 1990a, 1990b. In Czechia, the introduction of Sitka spruce into forestry practice is not yet anticipated, from a legislative viewpoint (Beran & Šindelář 1996).…”

Introduced tree species have become increasingly important in the context of the ongoing climate change. This paper focuses on the dendrochronology of the most widespread introduced tree species in the British Isles – Sitka spruce (Picea sitchensis [Bong.] Carr.) – in comparable soil conditions in England, Czechia, and Slovakia. The research aims to evaluate the growth dynamics and the influence of climatic factors on this tree species while comparing it with economically main tree species in Europe – Norway spruce (Picea abies [L.] Karst.). Based on the analysis of 150 increment cores, the radial growth of Sitka spruce was on average 24.2% higher than that of Norway spruce. The highest increments in 52 to 62-year-old stands were achieved in England by both Sitka spruce (8.7 mm) and Norway spruce (7.0 mm). In terms of negative pointer years (NPYs), there was no difference in the number of years with a significantly low increment between the two species at any site. The lowest effect of climatic factors on growth was found in Czechia, while the highest was in England. Higher resistance to climate was found for Sitka compared to Norway spruce. In general, the main limiting factor for the growth was the lack of precipitation in the previous year’s vegetation season, or heavy frost in England. In Central Europe, due to low precipitation, Sitka spruce will not be a substantial introduced tree species in the future, but on suitable sites, it can achieve high production potential and play a significant role for increasing stand diversity in the face of climate change.

“…Southern provenances, such as Washington and Oregon, have been found to be susceptible to autumn frost damage in comparison to Queen Charlotte Islands [11], and although the incidence of frost is predicted to decline in the future, sufficient risks remain to continue with Queen Charlotte Islands as the preferred option [2]. Sitka spruce, in common with most spruce species, requires a relatively high soil moisture status for good growth with an annual precipitation typically around 1000 mm or greater [12]. Sitka spruce can grow reasonably well with an annual rainfall of as low a 700-800 mm [13], but this would require consistent moisture availability particularly during the growing season and this cannot be guaranteed under predicted changes in the patterns of rainfall.…”

Building Resilience into Sitka Spruce (Picea sitchensis (Bong.) Carr.) Forests in Scotland in Response to the Threat of Climate Change

Abstract:It is expected that a warming climate will have an impact on the future productivity of European spruce forests. In Scotland, Sitka spruce (Picea sitchensis (Bong.) Carr.) dominates the commercial forestry sector and there is growing pressure to develop alternative management strategies to limit potential economic losses through climate change. This review considers management options to increase the resilience of Sitka spruce dominated forests in Scotland. Given the considerable uncertainty over the potential long-term impacts of climate change, it is recommended that Sitka spruce should continue to be planted where it already grows well. However, new planting and restocking should be established in mixtures where silviculturally practicable, even if no-thin regimes are adopted, to spread future risks of damage. Three potentially compatible species with Sitka spruce are western hemlock (Tsuga heterophylla (Raf.) Sarg.), grand fir (Abies grandis (Lamb.) Lindl.) and Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and all form natural mixtures in its native range in North America. The predicted windier climate will require a range of management inputs, such as early cutting of extraction racks and early selective thinning, to improve stability. The potential to improve resilience to particularly abiotic damage through transforming even-aged stands into irregular structures and limiting the overall size of the growing stock is discussed.
