Named after the city of Sitka in southern Alaska, this conifer is one of the most important tree species of the forest industry in Britain today.
The Sitka spruce - also known as Pica sitchensis - is able to adapt to a wide variety of site conditions and its high yield, especially in the wetter western regions, makes it our most successful upland plantation species.
