Iowa's Forestry

The Iowa DNR works to help Iowans expand and care for the state's roughly 3 million acres of trees and forests. We use professionally trained foresters and natural resource technicians to provide forestry assistance to private landowners, to sustainably manage our state forests, to operate the State Forest Nursery at costs of production, and to protect, utilize and enhance the state's forest resources for today and tomorrow.

Forestry services include the State Forest Nursery, forest health, urban forestry, landowner assistance, fire management and prescribed fire, educational opportunities, Iowa's wood industry and logging and fall color reporting.

Iowa’s Forests Today

The 2020 revision of Iowa’s Forest Action Plan is a comprehensive look at trees and forests across the state including in-depth assessments of past and present forest health, urban forestry, fire management, private lands management, forest productivity, and future conditions. The Forest Action Plan contains a set of strategic goals and strategies aimed at maximizing forest health and productivity, strategically growing Iowa’s forests, and promoting the benefits of Iowa’s forest resource.

Iowa’s 2020 Forest Action Plan is formatted as a user-friendly, engaging, and highly detailed webpage which allows users to interact with data, view high-resolution GIS maps on a street level, and look at historical trends of data over the past decade. This Forest Action Plan is best viewed on a computer versus a mobile phone and is optimized for the Google Chrome browser, but can be viewed on any web browser.

This Forest Action Plan also serves as a requirement of the U.S. Department of Agriculture, Forest Service for states applying for forestry-related federal funding.
