  • The future of Michigan's forests

    Forests provide many of the things we consider essential: clean air and water, habitat for wildlife, spaces for recreation and wood products for houses, paper and furniture.

    But Michigan’s forests face challenges. Insects and disease, wildfire, climate change and human use all need to be managed to help forests continue to thrive for generations to come. The Forest Action Plan includes an in-depth analysis of forest trends and conditions, and strategies to manage, preserve and protect these forests.

    2020 Forest Action Plan

    The 2020 Forest Action Plan consists of two parts:

    • An action plan
    • A landscape assessment of all forest resources in Michigan (public and private).

    Below, you will find information that describes the forest and its present condition and lays out forest management actions for the next 10 years.

  • Action Plan

    The action plan is a strategy that guides management activities to address issues and trends. It lays out goals for Michigan’s forests and how we can, collectively, achieve those goals. It’s renewed every 10 years and it can be updated as needed to account for unforeseen events such as wildfires and invasive species such as the emerald ash borer, which has laid waste to Michigan’s ash trees. This strategy, then, provides the basis for action over the 10-year term of this plan. This 2020 Forest Action Plan will address some statewide aspects (community wildfire and forest health) as well as private forest land in the state.

    Public input on the action plan

    The draft 2020 Forest Action Plan is now available for public review and comment. Comments can be made until Oct. 12, 2020. Submit comments to ForestPlanComments@Michigan.gov.

  • Landscape assessment

    The landscape assessment is meant to provide background in terms of status and trends for all forest planning in Michigan. The assessment tells us what Michigan’s 19.3 million acres of forest include: types of trees, where they grow, how many there are, how old they are and how healthy they are. It also describes many other aspects of the current forest.

    Public input on the assessment

    Please submit comments or questions about the landscape assessment to ForestPlanComments@Michigan.gov. If you need assistance accessing the story maps, please email DNR-GIS@Michigan.gov.

    The following are the key components of the landscape assessment. Click through each section to learn more about Michigan’s extensively forested landscape. These are presented as story maps that will open in a new window. You can also download a PDF version of the landscape assessment.

Ecological Areas in Michigan

  • What are ecological areas?

    Ecological areas are used to identify land and water areas at different scales that have similar functions and potential for management. Ecological areas are designed to have similar patterns in:

    • Plant and animal species
    • Soils
    • Water function
    • Land features
    • Rock formations
    • Weather and climate
    • Natural processes such as flooding, wind or fire

    Ecological areas can be large, broad areas, such as several states, or localized areas as small as a few square miles. Ecological areas can be subdivided, and refined in classification, based on the characteristics listed above. The hierarchy of ecological units is defined as:

    1. Eco-regions: Domains, Divisions, Provinces
    2. Subregions: Sections, Sub-sections
    3. Landscapes: Land-type Associations
    4. Land Units: Land-types, Land-type Phases

    The concept and use of ecological areas have been around for several decades. Much of the early work of defining ecological areas started in the 1980s and was further formalized in the late 1990s. The publication called the National Hierarchical Framework of Ecological Units offers more background and history of ecological area concepts.

    Why use ecological areas?

    To manage an ecosystem, we need to understand how it works.  In order to help us reach that goal, the data used in this landscape assessment has been collected using three sampling systems, which are:

    1. Social information is collected for each of Michigan's 83 counties
    2. Soil and water data (and to some extent vegetation data) are collected at the Hydrologic Unit Level 12 (HUC 12) scale, which focuses on local tributary systems. See the Soil Resources and Water Resources chapters for more detail.
    3. Land data are collected based on ecological sections and sub-sections. Click on an area on the map to learn more about the selected sub-section.
