Book Description
The annual forest inventory of Wisconsin continues, and this document reports 2001-05 moving averages for most variables and comparisons between 2000 and 2005 for growth, removals, and mortality. Summary resource tables can be generated through the Forest Inventory Mapmaker website at http://ncrs2.fs.fed.us/4801/fiadb/index. htm. Estimates from this inventory show a total of 16.1 million acres of forest land in the State. The estimate of total net volume of all-live trees on forest land is 22.3 billion cubic feet (ft3). In Wisconsin, timberland area totals 15.9 million acres, and net growingstock volume on timberland is 20.0 billion ft3. All-live, aboveground tree biomass on timberland is estimated at 597 million dry tons. Between 2000 and 2005, the average annual net growth of growing stock on timberland was 605.7 million ft3 per year. Average annual removals of growing stock totaled 362.5 million ft3 per year. Mortality was 176.4 million ft3 per year. These estimates generally show a healthy, growing forest despite more than 222,000 acres of forest that were defoliated by the jack pine budworm in 2005.

Book Description
In Every Root an Anchor, writer and arborist R. Bruce Allison celebrates Wisconsin's most significant, unusual, and historic trees. More than one hundred tales introduce us to trees across the state, some remarkable for their size or age, others for their intriguing histories. From magnificent elms to beloved pines to Frank Lloyd Wright's oaks, these trees are woven into our history, contributing to our sense of place. They are anchors for time-honored customs, manifestations of our ideals, and reminders of our lives' most significant events. For this updated edition, Allison revisits the trees' histories and tells us which of these unique landmarks are still standing. He sets forth an environmental message as well, reminding us to recognize our connectedness to trees and to manage our tree resources wisely. As early Wisconsin conservationist Increase Lapham said, "Tree histories increase our love of home and improve our hearts. They deserve to be told and remembered."
