| * | The area of administered acreage for each National Forest is the statistic used by IWFIA for area control, data compilation, and | |||||||||||||
| reporting. This acreage is based on the same year listed for the proclaimed acreage statistic. | ||||||||||||||
| ** | The area of proclaimed acreage for each National Forest is published annually in "Land Areas of the National Forest System, FS-383." | |||||||||||||
| The year listed refers to the publication year for the particular reference book used to acquire the proclaimed acreage statistic. | ||||||||||||||
| *** | This column is provided to explain why the administered acreage statistic and the proclaimed acreage statistic differ (when applicable). | |||||||||||||
| **** | Since the time of the field inventory, the Beaverhead and the Deerlodge forests have merged to form the B-D National Forest. | |||||||||||||
| ***** | The reported figure of 300,000 acres (USDA 1996) for the Bob Marshall reserved portion of the Lewis and Clark National Forest was not | |||||||||||||
| used in computing the Forest’s total reserved acreage. Instead we used an adjusted figure of 300,528 acres derived from the IWFIA | ||||||||||||||
| phase one points. This was due to county acreage discrepancies between IWFIA phase one points and NFS supplied figures for the | ||||||||||||||
| Lewis and Clark portion of the Bob Marshall Wilderness. | ||||||||||||||
