Habitat Tip: Don’t Move Firewood

Americorps • June 26, 2024

Now that it’s officially summertime and warmer weather is upon us, camping season in Michigan is in full swing! Camping is a very popular pastime for all Michiganders, and for good reason. From the thick forests and tall waterfalls of the Upper Peninsula to the setting sun on Lake Michigan after a long day on the water, Michigan is home to some of the most beautiful places in the country. According to the Michigan DNR Parks and Recreation Division, Michigan holds 103 state parks and recreation areas, and 140 state forest campgrounds. The state also boasts more than 13,750 state park campsites and over 250 cabins, yurts, and other overnight lodging. Parks and Recreation staff work tirelessly to ensure that campgrounds are clean and ready to use so campers will enjoy their experience visiting the state parks. However, campers also need to follow a few tips to help protect the environment around them, and one of the most important tips has to do with firewood.

Don’t Move Firewood

One of the most crucial camping tips is this: don’t move firewood! Invasive tree-killing insects and diseases can lurk in or on firewood and will spread to new areas. Eggs and small larvae of these invasive species are difficult to detect without careful inspection, so even firewood that looks clean and healthy can still pose a risk. New infestations can quickly establish and take over a large area, destroying the trees with them. Native trees have defenses against the insects and diseases local to their area, but if a new insect or disease reaches them, the trees have no way to defend themselves.

Once an invasive insect has spread to an area, it’s very expensive to control and eradicate them. According to the USDA (U.S. Department of Agriculture) Forest Service, the emerald ash borer has cost the USDA more than $200 million in surveys and control efforts since it was first detected. A study conducted by the Forest Service also estimates that 1.4 million trees will be killed by invasive insects from 2020 to 2050, costing an annualized average of $30 million (Hudgins et al. 2022).

How You Can Help

The best way to help mitigate the spread of insects and diseases is to not move firewood and only burn locally sourced firewood. This means buying firewood at the campground you are camping at and not transporting it from where you’re traveling from. In general, locally sourced firewood is referred to as the closest convenient place that you can purchase it from. As a rule of thumb, only use wood cut within 50 miles of where you are having your fire. You can also purchase heat-treated wood, which is considered safe to move. It must be packaged with a USDA APHIS (Animal and Plant Health Inspection Service) heat treatment seal or a state-based (such as a State Department of Agriculture) heat treatment seal. Firewood that is labeled “kiln-dried” is different and not considered safe to move.

On the Ground Junior: Fall Event Recap

By Olivia Triltsch • October 16, 2025
In 2025, the On the Ground program conducted 8 junior projects with schools involving 316 students from across the state. From tree plantings to invasive species removal, these students worked to enhance 39.3 acres of public land after contributing over 200 volunteer hours. Visit our website to learn more information about our On the Ground program and On the Ground Junior . To wrap up the 2025 field season, the On the Ground program worked with two classrooms to enhance wildlife habitat and recreational access. Junior programs like these allow teachers to get their students out of the classroom and into hands-on learning about the importance of habitat work while meeting individuals in the field.
