Introduction
"Invasive species have two main characteristics: they are non-native (exotic/alien) to the ecosystem that they occupy, and their existence in that ecosystem causes or is likely to cause harm to the economy, environment, or human health. If left unchecked, invasive species can threaten native species, biodiversity, ecosystem services, recreation, water resources, agricultural and forest production, cultural resources, economies and property values, public safety, and infrastructure."
According to a report from The Weather Channel, invasives may be driving as much as 60% of extinctions, while threatening our food supplies, spreading diseas, and costing $423 billion in costly damages.
What To Do About Invasives
What To Do About Invasives
In some cases, you can simply pull out invasive weeds, and put them through a chipper (this may help some invasives spread), into a compost (watch out for seeds!), a burn pile (which contributes to air pollution), and some may be appropriate for turning into plant fertilizer.
In some cases invasives can be fed to animals or even eaten by humans.
To learn more about why it can be extremely important to track, identify, and handle invasive species, please check out our Handle Invasive Species page.

Recipes for Invasives
Eat The Invaders This resource lists problematic invaders, and offers information like where the originated, and where they are considered invasive to help you decide if they need to be removed, as well as recipe suggestions. Most are animals, but there are also plants and even seaweed!
Words of Caution!
Words of Caution!
One drawback to finding uses for invasives is that it might promote people to retain or even purposeful raise/farm the invasives if they become too useful or popular.
It's also very important to identify a species correctly before handling, harming, or consuming it. Some species (especially plants and fungi!) may be poisonous, but look almost exactly like a non-deadly counterpart.
When extracting plants, be careful to remove as much root as possible, since aggressive plants can easily come back from even tiny root remnants.
Similarly it is best to destroy plants before they can seed. Sometimes handling the plant is enough help the seeds explode everywhere.
Some species such as hogweed are particularly dangerous. Causing serious pain, and dangerous sensitivity to sunlight.
Hogweed is One of Canada's Most Dangerous Plants, Here's What You Should Know
2:42 minute video explains that "If you touch the sap of giant hogweed, it could lead to 3rd-degree burns. That's why The Weather Network's Mark Robinson dons a hazmat suit to learn about how to remove Canada's most noxious weed."
Hogweed grows along trails or near water, and looks similar to Queen Ann's Lace.

Asian Hornet is a non-native species within the UK and could have a serious impact on our insects including honeybees so early detection is important. There are a number of native insects in the UK that look very similar to the Asian Hornet, and are common and widespread. Asian Hornet Watch provides an identification guide to help check which species you have seen and an opportunity to record your sightings. Insect identification can be difficult and so please do include a photograph with your record to help us confirm the identity of the species you have seen." Also on the AppleStore.

Invasions of nonnative plants into forests of the Southern United States continue to go unchecked and only partially unmonitored. These infestations increasingly erode forest productivity, hindering forest use and management activities, and degrading diversity and wildlife habitat. Often called nonnative, exotic, nonindigenous, alien, or noxious weeds, they occur as trees, shrubs, vines, grasses, ferns, and forbs. This app provides information on accurate identification of the 56 nonnative plants and groups that are currently invading the forests of the 13 Southern States."

Bighorn sheep are a community-wide iconic wildlife species that depends heavily on intact winter range and migration corridors. Rapidly responding to invasive species infestations will help maintain habitat for this and other wildlife species in the area.
Everyone can help! All you have to do is upload the iNaturalist app onto your devise, join the project (Dubois Invasive Species Watch), and while you’re out and about hiking, riding or exploring the beautiful landscapes around Dubois within the project area, keep your eyes out for some of the more common (and wildlife-challenging!) invasive species and make observations with your phone. The specific locations, photos and descriptions of the plants you see will be uploaded to the project site and used in real-time by habitat biologists.
We hosted a free zoom training for volunteers on May 28, 2020, and a link to this recorded video session can be viewed by clicking this link. You can also see the powerpoint itself (without video) by clicking this link: DuboisInvasiveSpeciesWatchTraining."
