Figure 2 Distribution
Region Widely distributed throughout western North America, extends from Alaska down in to the Baja of Mexico, and over to South Dakota. Other variants from Alaska into the Northwest Territories to the east into Saskatchewan down to the Black Hills of South Dakota and southern Colorado, central Utah and eastern Oregon Highly adaptable/ grow in all sorts of environments (bogs-dry sandy soils) Cold Hardiness Zone 2-8

Wood Sapwood- White to pale yellow Heartwood- White to pale yellow (only slightly darker than sapwood) Odor- Distinct resinous odor Latewood band-Usually narrow Resin Canals- Present but difficult to see (may form dark streaks along grain) (Difficult to distinguish from Ponderosa Pine, but more heavily dimpled on tangential surface than Ponderosa
Uses - Lumber, plywood, paneling, Logs for log homes, doors, windows, furniture, railway ties, mine props, fence posts - Cambium stripped off in spring for food, pitch boiled with fat for medicine or used for sore throats - Used in landscapes- not really dense and allow light through - Yard tree, park tree, windbreak (depending on Windbreak Suitability Group- 1,3,4,5) (7). - Cultivars like the ‘Frisian Gold, ‘Chief Joseph’ and ‘Taylor’s Sunburst’ produce gold-needles during growth in the spring.

Figure 4 Pollen cones
Reproductive details - The lodgepole pine produce serotinous or nonseritonous cones mainly in the upper canopy, while on the older, less dominant branches of the lower canopy produce the pollen cones.

Maintenance - Pruning (rarely required/ deadwood removal or double leaders)
Limitations - Diseases: Comandra blister rust, needle blight, needle cast, needle rust, pine-pine gall rust, Stalactiform blister rust, Dwarf Mistletoe (parasitic herbivore) (10) - Rabbits, deer will eat during the winter, pests- mountain pine beetle - Soil pH- 5.0 to 7.5 (7) - Drought resistant (7) - Root growth in impermeable layers or shallow, stony soils potential for wind throw(7).
