Invasive Plants & Animals
Help! We're being invaded by ALIENS! Learn what you can do to help.
What is an Invasive Species?
An invasive species is a non-native species whose introduction does, or is likely to, cause economic or environmental harm or harm to human health. An invasive species can be a plant, animal, or any other biologically viable species that enters an ecosystm beyond its native range.
Invasive Plants: these invaders are what you might call "noxious weeds." Some are beautiful, some are ugly, but they are all tough and adaptive. Many of them have already conquered vast stretches of the lands and cities out here in the West. Some of them may be in your own backyard!
Did you know? If you travel in the forest with livestock, weed-free feed is required. Click here to learn more Weed Free Feed and good livestock management practices.
Check out our Invasive Plants Treatment page for detailed maps of known invasive plant infestations and proposed treatment areas with 12 maps covering the Deschutes & Ochoco National Forests and the Crooked River National Grassland.
Where are Invasive Species?
They are everywhere across Oregon. Check out the Quick Guide at OPB for an interactive map that shows the distribution of these aliens across Oregon.
How Can You Help?
You can help reduce the spread and infestation of invasive species. Learn how the aliens are introduced and spread.
Quagga and zebra mussels are among the most devastating aquatic invasive species to invade North American lakes and rivers and could potentially spread to Northwest waters via boats. The Fish & Wildlife Service has a great video to help you understand the problem: http://www.youtube.com/usfws#p/c/0/Ntpumy975f0
Please follow these prevention practices:
Clean Your Gear - Enter public trails with clean shoes and clothing. Wash boots before hiking into a new area. Inspect and clean packs, equipment, and tires.
Check Your Pets and Livestock - Be aware of the potential for pets and livestock to collect and carry weed seeds in fur and hooves. Simply brushing animals, boots and clothing before leaving sites will help prevent the spread of noxious invasive weeds to other areas.
Know your equipment - Routine checks of your equipment such as trailers, all-terrain vehicles, and trucks can often reveal plant parts and seeds hidden in the frames and undercarriages. Inspect and clean motorized and mechanized trail vehicles of weeds and their seeds at a controlled site.
Use Weed Free Forage and Bedding - Support the development and distribution of weed-free feed, hay, straw, and mulch, and use it during your visit.
Avoid moving through areas with weed infestations whenever possible.
Avoid picking unidentified “wildflowers” and discarding them along trails or roadways.
