Revised Aerial Volume Table for Estimating Spruce and Fir Mortality in Minnesota

Key Points

The revised aerial volume table improves accuracy in estimating spruce and fir mortality.
Field measurements reveal that previous estimates from the 1965 table were invalid.
Spruce budworm activity significantly impacts white spruce and balsam fir populations in northern Minnesota.
The revised estimates aim to support better forest management practices amid current pest activity.

Abstract

Abstract An aerial volume table for use in estimating mortality in white spruce and balsam fir caused by spruce budworm in northern Minnesota was published in 1965. Since then its validity has been tested by comparing photo interpreters' estimates with field measurements of tree volume losses. The published table does not appear to be valid, and a revised table is suggested for use during the current level of spruce budworm activity.
