MSxk2/110 Trapper's tea - Bunchberry - Glow moss

Sites subject to cold air accumulation and have seepage in upper soil horizons. Forest a mix of Pl and Sx with minor Bl.

Future feasibility show decline in Pl Sx to about 50% and sharp decline in Bl. Fd shows increase in suitability to about 75%.

Again, these are cold air drainage sites subject to frost hazards and so it is risky to plant Fd on these sites in the near future. I think the initial models that start with a IDFdk1-like environment are over-promoting Fd. I think Pl and Sx are still the best options. I susupect Fd suitability is more likely similar to that of Lw for this site series.

No files, tests, or entry points are named. Start by reviewing the species feasibility model and the cold-air drainage assumptions described here; the issue needs an agreed target for Pl, Sx, Bl, Fd, and Lw suitability before completion can be verified.
