We collect the cones from our proven resistant sugar pine and western white pine seed trees in mid-September when the seeds are ripe, but still encased in sticky, green cones. 

To collect the cones from proven resistant seed trees, a climber ascends the tree with ropes, harness, and the appropriate safety equipment. Once at the top of the tree, the climber shakes or mechanically clips the cones off the limbs. All of the cones from proven resistant seed trees are harvested each year.

We share our crop with the US Forest Service; they get 50% of our cones for seed banking purposes.  We send the rest to CalForest Nursery in Etna, CA to germinated and grown up in to one year-old seedlings. The young seedlings are planted in reforestation and restoration projects throughout the Tahoe Basin and surrounding areas.
