Once the pine cones are collected, they're brought to a network of nurseries, where the seeds are extracted and grown into seedlings. One million seedlings will plant about 4,500 acres of new forest.
Closed-cone forests rely on regular but infrequent fires, often stand-replacing crown fires. Fire opens up space in the canopy or clears away litter on the ground, so there is less competition for germinating seeds. Thus, the fire is an advantageous time for trees to drop their seeds.

Resin is usually collected by causing minor damage to the tree by making a hole far enough into the trunk to puncture the vacuoles, to let sap exit the tree, known as tapping, and then letting the tree repair its damage by filling the wound with resin.
Stick to pine, fir and spruce trees. Cedar, cypress and especially yew trees should be avoided because they can be toxic or inedible. Beware trees sold at grocery stores or in parking lots that ...
