(FR, UK) Spatial modelling of species suitability to sites and climate projections

The infrastructure skills have already been used in tree breeding to investigate suitability of both Sitka spruce (Picea sitchensis) and Douglas Fir (Pseudotsuga menziesii) provenances at the Great Britain level. The infrastructure is now ready to expand to the European level using skills, data and expertise which will be developed in Trees4Future. On a more general level, the infrastructure has been used to model the suitability of species across Britain into the future in response to climate change projections, and also suggest appropriate new species. There is widespread interest to develop these skills across Europe since the projections generated by the infrastructure enable costed alternative scenarios regarding how the breeding programmes for different species should be shared, or not. 

Examples of use


Sitka spruce map - UKSitka spruce provenance zones map of Great Britain

  • Sitka spruce (Picea sitchensis) seed origin suitability map for Great Britain. Chapter 6 from Choices of Sitka spruce Seed Origins for use in British Forests (2007) Forestry Commission Bulletin 127; Forestry Commission, Edinburgh, Scotland. 112 p. FC online catalogue.

The figure shows areas of Great Britain in which different origins of Sitka spruce are likely to be suitable, depending on the suitability of soil, slope and other topographic factors. Grey shading - unsuitable for Sitka spruce; Yellow shading - suitable for Sitka spruce Queen Charlotte Island Origin; Red shading - suitable for Sitka spruce Washington Origin; Brown shading - suitable for Sitka spruce Oregon Origin.

 

 

 


Douglas fir provenance zone map of Great Britain

  • Douglas Fir (Pseudotsuga menziesii) seed origin suitability map for Great Britain. Chapter 6 from Choices of Douglas Fir  Seed Origins for use in British Forests (2010) Forestry Commission Bulletin 129; Forestry Commission, Edinburgh, Scotland. 56 p. FC online catalogue.

The figure shows areas of Great Britain in which South Washington Cascades Origin (SWCA) origins of Douglas fir can be expected to show increased height growth (expressed as a percentage increase) over Washington Coastal origin (WACO origins) including extrapolation into areas lying outside the range of variables used in the predictive model. Douglas fir suitability is indicative and is additionally dependent on soil, slope and other topographic factors.
