Iowa’s Forest Cover Iowa’s forests cover 8% of our landscape 87% of our 2,97,000 acres are owned by private landowners (FIA) 26+ million urban trees

Why the Increase from 1974-2011? Pasture land reverted to timber due to the decline of the cattle industry. In Western Iowa successional trends from prairie to woodland species (red cedar).
5
Why the Decrease from 2011 - 2013? Forest Service Forest Inventory Analysis data caught up with forest clearing that occurred during the time of high commodity prices
6
Timber Loss/Gain From 2009 - 2013 Iowa lost 192,000 acres (6%) of existing forest land This loss was offset by a gain of nearly 95,000 acres (3%) of land newly designated as forest land Net Loss 97,000 acres
7
Timber Loss 77% - Agricultural Conversion (Cropland, Pasture, Range, Other) 15% - Water or Marsh 4% - Right of Ways 4% - Development
8
Timber Gain 60% - Ag Land (mostly crop ground) 18% - Water/March 15% - Developed Lands 7% - Right of Ways

Good News Iowa has over one billion trees and at least 60 tree species Average annual growth is three times larger than average annual harvest removals
