Invasive Species & Our National Forests

Nonnative invasive species (NNIS) are entering the United States at accelerating rates due to global travel, trade, and expanding human development, posing a serious threat to forest ecosystems. As summarized in Impacts of Nonnative Invasive Species on U.S. Forests and Recommendations for Policy and Management, these species can alter ecological trajectories, suppress rare native plants and animals, reduce forest productivity, and degrade wildlife habitat. Under Federal Executive Order 13112, agencies are required to prevent introductions, control established invasives, and educate the public. The report defines key concepts such as alien species, introduction, control, native species, and invasive species, emphasizing that invasives are those nonnative organisms likely to cause economic, environmental, or human‑health harm. Recognizing the scale of the problem, the Society of American Foresters convened a team to assess NNIS impacts and outline feasible strategies to maintain sustainable forests.

The authors recommend expanding early detection, strengthening quarantine enforcement, improving forest‑health training, building scientific and operational capacity, and increasing cross‑agency collaboration. Volunteers play a critical role in this work. Citizen stewards can help by learning to identify common invasive plants and pests, reporting new sightings, participating in removal events, cleaning boots and gear to prevent spread, and sharing information within their communities. Because NNIS threaten the ability of future generations to benefit from healthy forests, only a sustained, coordinated effort — supported by agencies, policymakers, and engaged volunteers — can meaningfully address the challenge.

How can you help? We're hosting an event at Pincushion Mountain on September 22, and we'd love to have you join us. Learn more here!

Thanks to our amazing board member Ann for her thoughtful examination of NNIS.

Up in Smoke: A Sioux Hustler Trail Project

The goal: Paddle into the Boundary Waters Canoe Area Wilderness (BWCAW) with a small team to clear a very remote section of the Sioux Hustler Trail. This is a 30-mile loop that requires stewardship from several groups such as the Boundary Waters Advisory Committee and Wilderness Volunteers, and Friends of the Superior National Forest was excited to be part of this work. We were tasked with clearing the trail from Heritage Creek to Pageant Lake.

The team: Friends of the Superior National Forest's Wilderness Project Coordinate Dan Wilder was joined by two incredible volunteers, each with a ton of experience.

Our crew at Fenske Lake Campground

The team left around noon on July 9 for a 4-night basecamp, but it was going to be a long paddle to get to their site. Distant fires were burning, but there was no immediate cause for concern.

Until there was.

The same day the crew paddled into the BWCAW, the Sioux Fire began. By the time the crew checked in via satellite communicator that evening, paddlers were already being told to evacuate the area. The Sioux Hustler Trail was soon officially closed, and the following morning, having just gotten settled into the campsite, the team had to pack up and begin the arduous nine-mile paddle back to their entry point.

Although the team did not make it to the section of the Sioux Hustler Trail they intended to steward, on their way into and out of the area, they were able to accomplish some important work, including:

• 1 dead birch tree felled

• 1 tree removed from the Devil's Cascade Portage

• 2 campsites maintained

• 2 fire grates cleaned

• 3 latrines assessed and reported to the U.S. Forest Service

The team returned safely to the entrypoint around sunset on the day after going in. According to Dan Wilder, "Their flexibility, teamwork, and positive attitudes turned an unexpected evacuation into a rewarding stewardship experience."

We're incredibly grateful for our volunteers during what turned into a much more stressful trip than anticipated. We also wish to extend a huge thank-you to Tom Yankowiak with the U.S. Forest Service for helping us to assess the situation so we could relay messages to our team.

The fires impacting the Superior National Forest have made national news this summer, and the impact to the forest is severe. We're still planning some work in the BWCAW this summer - hopefully without an evacuation this time - and we'd love to have you join us.

CASP volunteers fulfill mission of service on the Superior National Forest

Volunteers are vital to keeping public lands open and accessible. Most of our volunteers contribute a few hours or days, but others contribute weeks, months, or even an entire season. Groups who can volunteer for longer stretches help public land management agencies to complete more technical or longer duration projects. In 2025, with support from the Friends of the Superior National Forest, the Superior National Forest hosted the Conservative Anabaptist Service Program (CASP), whose members volunteered for an entire month working alongside recreation and heritage Forest Service staff.

CASP’s vision is for its participants to fulfill their call of service through volunteerism by responding to the nation’s need for labor in forestry, conservation, or disaster project work.  Seven young men ages 18-20, from across the county, spent 22 days this past fall working on trails and portages in the Superior National Forest and Boundary Waters Canoe Area Wilderness (BWCAW). They completed an astonishing 1,400 hours of service work!

“I wanted to do CASP to support the country in a non-resistant way. I don’t believe in the violence of war, but I want to support the country. My brothers have also done CASP, and I’ve heard good things about it. I also like camping out in the woods, so this was a great fit.” – Irvin Miller, one of four immediate family members that has done CASP trail service work.

The volunteers completed the following: 

• Resurfaced almost a mile of BWCAW portage with gravel, built two 30’ rock turnpikes (a trail feature that elevates the trail to keep it dry), and installed 49 drainage and erosion control features. 

• Repaired an 80’ rotten boardwalk by disassembling it, leveling it with jacks and replacing the deck boards. 

• Built a new wooden stairway at a recreation area, cleared vegetation along trails at a Nordic trail system, brushed and cleared a four-mile portage trail, and helped staff maintain and restore several historic log cabins.

The volunteers were surprised at how friendly visitors were to them, stopping to talk and thanking them for their work. We're incredibly grateful for these CASP volunteers and the Forest Service staff who coordinated their work! Special thanks to Christine Kolinski for her work on this story.

Are you interested in volunteering to meet new people, gain new skills, and give back to the public lands around you? Friends of the Superior National Forest would love for you to join us! We'll be announcing our 2026 projects soon!
