Sitka spruce-associated biodiversity in the UK (Sitka spruce Ecol)

Existing data sources were collated during 2023/24, in order to identify as comprehensively as possible those species that use Sitka spruce, Picea sitchensis (Sitka spruce-associated species) and the nature of this association in the UK. The data sources included quality controlled databases of records of species, peer reviewed literature, published books and grey literature. A complete list of data sources used is provided together with an assessment of the quality of that data: peer reviewed or quality controlled dataset versus grey literature and whether the data are from the UK or not. Information on the species ecology and their use of 34 other tree species was also collated. The data were collated in a pre-defined standard format to enable consistency across taxa.
