Status of Whitebark Pine – Introduction

Status of Whitebark Pine in Crater Lake National Park, Oregon, 2000


Whitebark pine (Pinus albicaulis) is an important tree species that provides food and shelter to high mountain wildlife plus scenic woodlands for visitors. About 500 acres of whitebark pine thrive in Crater Lake National Park where the trees are found perched on crater rims and mountains higher than 7000 feet. An introduced fungus (Cronartium ribicola) infects whitebark pine and causes the disease, white pine blister rust, which is usually fatal. Because of the threat this disease poses to the Park, our objective was to assess its significance on the Park’s whitebark pine. We provide a discussion of our results and management recommendations.
