Every year, many homes in the Great Lakes region are damaged or destroyed by wildfire, yet nearly all of these homes could have been saved if owners had followed a few simple rules. Having undeveloped woodlands and fields in and around a neighborhood means residents should know how to prepare their homes. Two types of wildfire: surface and crown. Surface fires burn pine needles, leaves, grass, downed logs, stumps, tree limbs and low shrubs. Crown fires move through the canopy. Experts recommend keeping the first 3-to-5 feet around the base of the house and any outbuildings completely free of any fuel for a fire. Leaves, pine needles, straw bales, and organic landscaping mulch can host a smoldering fire long after the main fire has passed. In the Great Lakes region, red pine and jack pine are the most flammable tree species and are known to carry burning embers up to a mile ahead of the fire front. If your home is surrounded by a pine forest or is built in the middle of a pine plantation, thin the trees and keep them pruned and free of dead wood out to 200 feet from your home. Remove any dead standing trees. These trees can turn into chimneys, spewing hot firebrands. Raking leaves into the woods can also be dangerous. Named Firewise Plant profiles (including nannyberry and columbine) plus a sampling of suggested firewise plants also suitable for shoreland buffers.","asOf":"2026-08-25T00:00:00.000Z","object":{"kind":"guide","id":"what-uwex-and-the-dnr-agreed-on","title":"What UWEX and the DNR agreed on","url":"/guides/what-uwex-and-the-dnr-agreed-on/"},"source":{"title":"Firewise Landscaping — A Guide to Protecting Your Home from Wildfire (GWQ 049 / DNR PUB-FR-417-2008)","url":"https://cdn.shopify.com/s/files/1/0145/8808/4272/files/GWQ049.pdf","publisher":"University of Wisconsin–Extension and Wisconsin Department of Natural Resources","sourceType":"official","accessedOn":"2026-08-25T00:00:00.000Z","documentDate":"2009-02-01T00:00:00.000Z"}},{"id":"guide:what-uwex-and-the-dnr-agreed-on:2","anchor":"local-us-wi-what-uwex-and-the-dnr-agreed-on-2","place":"Wisconsin DNR Ready, Set, Go!

Studies show that as many as 80 percent of the homes lost to wildfires could have been saved if their owners had only followed a few, simple Firewise practices. The Wisconsin DNR and local fire departments take every precaution; in a major wildfire there will simply not be enough fire resources to defend every home. Firebrands can be carried more than half a mile. Home ignition zone out to 100–200 feet. Zone One 3–5 feet around home, deck, porch and outbuildings: remove anything that can burn; if you plant, choose deciduous over evergreens; bare dirt or rock mulch better than wood mulch. Zone Two 5–30 feet: lean, clean and green; trim branches within six feet of the ground and ten feet from roofs; choose deciduous over evergreens. Zone Three 30–100 feet: 20 feet between trees; favor deciduous. Zone Four 100–200 feet: for homes built on slopes and in pine plantations, remove woody debris on the forest floor; thin canopies.
