Picea engelmannii
- Scenery
The entire forest of Picea engelmannii at Cedar Breaks National Monument has been killed by Spruce Bark Beetles. Only the very young trees survived. It started in the late 1990's and spead southward through the Park. Since Picea engelmannii was the dominent tree in the park, it has had quite a devastating effect, leaving only scattered trees of Abies lasiocarpa bifolia, Pinus flexilis and Pinus longaeva. It has nearly reached the limits of Picea engelmannii in the mountains around Cedar Breaks, but has not yet spread to other surrounding highlands were Picea engelmannii is found.
