Presentation on theme: "Pending work on technical aspects of CBST"— Presentation transcript:

1 Pending work on technical aspects of CBST
Transform variables to better represent non-uniform distributions of climates Complete the development of transfer functions for remaining species

2 Recent work on the seedlot selection tool
Species selection pertains to the site, not the seedlot Species selection to be used as a red flag instead of an axe.

3 Cutblock Procurement area Species distribution (current)

10 Seedlot Seedlot suitability area Species distribution (current) Seedlot deployment area Deploying seed only to overlap area ensures that both the species and seedlot are climatically suited to the site.

12 Tongli’s species distribution modelling
PoP 1975 for each pixel PoP 2025 for each pixel PoP 2055 for each pixel PoP 1975 for each BECvar PoP 2025 for each BECvar PoP 2055 for each BECvar 1975 climate data for each pixel Botanical plot data (42,000 pres/abs) USDA FS FIA plot data (11,000 pres/abs) 1975 climate data for each plot Random Forests 2025 climate data for each pixel Model 2055 climate data for each pixel

14 Preferred/acceptable
Unacceptable This approach to identifying minimum species suitability is being reviewed by Tongli. Likely to be highly species specific.
