AREAS WITH TREE MORTALITY FROM
BARK BEETLES
SUMMARY FOR 2000 – 2014
WESTERN US
15 YEAR FOOTPRINT FOR MOUNTAIN PINE BEETLE = 24.3 M ACRES
15 YEAR FOOTPRINT FOR ALL WESTERN BARK BEETLES = 49.8 M ACRES
Many areas of pest activity overlap from year to year. The footprint area is the cumulative area covered by pest
activity with no double counting of acres between years.
*Spike in all western bark beetle acres in 2003 due to increased survey of pinyon pine mortality in the Southwest.
BARK BEETLE SPECIES INCLUDED:
California fivespined ips
cedar & cypress bark beetles
Douglas-fir beetle
Douglas-fir engraver
Douglas-fir pole beetle
fir engraver
flatheaded borer
ips engraver beetles
Jeffrey pine beetle

roundheaded pine beetle
silver fir beetle
southern pine beetle
spruce beetle

twig beetles
western balsam bark beetle
western cedar bark beetle
western pine beetle
Complexes, insect/disease and other multi damage phenomena that contain a bark beetle component like fiveneedle pine decline, subalpine fir mortality, true fir pest complex and pinyon pine mortality are also included.

may be significant overlap from year to year. Numbers are from the National Insect & Disease Survey database.
