🚐 Taking the RV on a fall adventure? Leave the firewood behind.
When we travel from one destination to the next, bringing firewood along can also give invasive insects and diseases a ride to somewhere new.
This #FirewoodMonth, make local firewood part of your travel plans:
🪵 Buy firewood where you’ll burn it
🪵 Choose certified, heat-treated firewood
🪵 Gather firewood at your destination where permitted
Whether you’re staying close to home or exploring somewhere new, simple choices can help protect the forests, campgrounds, and outdoor spaces we enjoy along the way. 🌲
Travel responsibly. Keep firewood local. Protect the places we love.

🔎 Spotted lanternfly can hitch a ride in a way that’s easy to overlook: as an egg mass.
Females lay egg masses on trees and many other hard surfaces—including firewood. Moving infested materials can give this invasive pest a ride to a new location.
During #FirewoodMonth, help stop unwanted hitchhikers before they travel:
🪵 Buy firewood where you’ll burn it
🪵 Choose certified, heat-treated firewood
🪵 Gather firewood on site where permitted
And keep an eye out for spotted lanternfly and its egg masses on firewood and other outdoor items. Knowing what to look for is another way we can help slow the spread of invasive species.

As summer gives way to fall, keep an eye out for sericea lespedeza (Lespedeza cuneata) — an invasive plant that can take over grasslands, pastures, roadsides, and other open areas. 🌿
Introduced from Asia, sericea lespedeza is recognizable by its small leaves made up of three narrow leaflets and clusters of cream-colored flowers, often with purple markings. It flowers in late summer, followed by seed production as the growing season winds down.
Sericea lespedeza spreads primarily by seed. Seeds can be dispersed by animals and moved through human activities, including on vehicles and equipment or in contaminated soil and plant material. Once introduced, this tough plant can form dense stands that compete with native vegetation, reduce plant diversity, and provide poor-quality forage for many grazing animals.
That makes fall an important time to think about where seeds might be traveling. Whether you're hiking, working, hunting, riding, or exploring open landscapes, clean mud, seeds, and plant material from your footwear, clothing, vehicles, and equipment before heading somewhere new.
A few minutes of cleaning can help keep invasive seeds from traveling with you.

We’re excited to share that a PlayCleanGo boot brush station has been installed at Calamus Reservoir State Recreation Area in Nebraska, thanks to grant funding from the U.S. Fish and Wildlife Service through the Infrastructure Investment and Jobs Act!
Located in the heart of Nebraska’s beautiful Sandhills, Calamus Reservoir is a popular destination for camping, fishing, boating, hiking, and other outdoor adventures. The recreation area is managed by the Nebraska Game and Parks Commission in partnership with the Bureau of Reclamation and includes a large reservoir surrounded by rolling grasslands and important native habitats.
With visitors moving between trails, campgrounds, shorelines, and other recreation areas, seeds and plant material can easily hitch a ride on boots and gear. This new station makes it easy to PlayCleanGo and help prevent invasive species from spreading into the places we love.

Those tall, prickly plants along roadsides and open areas might be cutleaf teasel (Dipsacus laciniatus) — and by late summer and fall, they can be carrying thousands of seeds ready to spread. 🌱🥾
Introduced from Europe and Asia, cutleaf teasel can grow several feet tall and is recognizable by its prickly stems, deeply divided leaves, and distinctive oval flower heads. During the growing season, small pale purple to white flowers appear in bands around the flower head. Later, the dried seed heads can remain standing well beyond the growing season.
Cutleaf teasel reproduces by seed, and a single plant can produce thousands. Seeds generally fall near the parent plant, but people can help them travel farther when seed or contaminated soil and plant material are moved on footwear, vehicles, tools, and outdoor equipment.
Once introduced to a new area, cutleaf teasel can form dense stands along roadsides, fields, grasslands, and other disturbed sites, competing with native vegetation and reducing habitat quality.
If your late-summer adventures take you through an infested area, check your boots, clothing, pets, and gear for seeds, mud, and plant material before moving on. Cleaning up before visiting another site is a simple way to keep invasive plants from coming along for the ride.

🎣🍂 Cooler mornings, changing leaves, and time spent on the water—fall fishing season is just around the corner!
Whether we're casting from shore, heading out in a boat, or wading into a favorite fishing spot, we all have a role in keeping the waters we enjoy healthy.
We protect our favorite fishing spots by cleaning plants, mud, and other debris from our boats and gear, draining all water, and allowing everything to dry before visiting another waterbody.
These simple steps are part of how we care for the places where we fish, explore, and make memories.
Wherever the season takes you, let's keep protecting the places we love. 💚

Another late-summer hitchhiker to watch for: jointed goatgrass (Aegilops cylindrica). 🌾🥾
Jointed goatgrass is an invasive grass found across much of North America. Its narrow, cylindrical seed heads are made up of distinctive segments or “joints.” As the plant matures, these seed heads break apart, allowing the individual seed-containing segments to disperse.
Those seeds are equipped with stiff awns that can catch on clothing, footwear, animal fur, and equipment. Seeds can also be moved in soil or mud on vehicles and machinery, making human activity an important pathway for this invasive grass to reach new places.
Jointed goatgrass grows along roadsides, disturbed areas, rangelands, and agricultural fields. It is particularly troublesome in winter wheat because the two grasses are closely related, making jointed goatgrass difficult to manage without also affecting the crop.
Whether you’re hiking, working outdoors, or exploring open landscapes, check your shoes, socks, pant cuffs, pets, and gear before moving to another location. Removing seeds before they hitch a ride is a simple way to help protect the next place you visit.
