Whitebark Pine Seedling Trials

Dozens of whitebark pine seedlings are planted in rows at a tree nursery. When the cones are mature, the seeds are collected. Some are sent to tree nurseries to grow; others are saved in a seed bank. At the nurseries, it’s a waiting game. Tiny seedlings are put through multiple trials to see how resistant they are to blister rust. Many seedlings are planted back in the national parks.
