Blues Reference Conditions Forest Structure
Moving Toward Reference Setting 1 – Increase the dominance of western larch (with lodgepole) and ponderosa pine. Increase patch sizes for large and giant sized trees. Shoot for at least 20% of area in LG size classes with at least half of that in closed conditions. At least half area of LG forests should be in large patches. About 20% of the area should be in grass/forb/shrub and seedling/sapling conditions. DRAFT – Subject to change
Moving Toward Reference Setting 2 – Increase the dominance of ponderosa pine. Large patches (well over 100 acres) of LG should dominate, forming more than 30% of the area. LG patches should be highly connected. Open patches (mostly < 20 acres) of grass/forb/shrub and seedlings/saplings should occupy 8-10% of potentially forested area. DRAFT – Subject to change
