Jeffrey Pine seeds

Does anyone live in the Central or Northern Sierra Nevada, and have access to Jeffrey pine seeds?

I want to see how well Jeffrey pine (a close relative to Ponderosa pine) will grow in the ever warming climate here in Montana.

I'm planning on starting the seedlings in my "nursery" this winter (re-claimed overhead fluorescent fixture strung up in my basement with good lights), and then planting them on some family land that is almost monotypically interior Doug-fir.

I would prefer seeds from the high (cold) and dry range of Jeffrey pine, and would trade you seeds of grasses, shrubs, or trees from around here, as per your preference. Need any serviceberry? Prairie smoke? Larch or limber pine?

Thanks!
