Invasive Species Action Network

With new friends joining us for #NISAW2025 we'd like to reintroduce ourselves. ISAN is a non-profit dedicated to reducing the human caused spread of invasive species by working with the public, private industry, and government entities. Learn more at stopais.org.

TOMORROW join ISAN for a pint at Neptune's Brewery in #LivingstonMT to support #InvasiveSpecies prevention & celebrate @GiveaHoot49!🍻 We'll be there from 4 - 7 pm tomorrow, July 9th to talk all things invasive species. Can't make it? Consider donating at give-a-hoot.org/organization/i…

We had an absolute blast at the Royal Gorge #Whitewater Festival!🌊 Congratulations to all the athletes & thank you to everyone who stopped by to chat with us about #invasivespecies. No matter what you float, practice #CleanDrainDry to protect our waters for generations to come.

Last week, we had the opportunity to lead two workshops for students at the annual 2025 Montana #4H Congress🐎✨ Students learned about preventing #invasivespecies & practiced #outreach by creating "mock" social media posts. Click through to see some of their amazing creations!

Common household pets, such as red-eared sliders, pose a significant threat to native wildlife when they escape enclosures or are intentionally released into the wild. Help #ProtectOurWaters and #DontLetItLoose! Learn more at dontletitloose.com. #InvasiveSpecies #4good4GYE

Responsible #hikers are stewards of the outdoors and prevent the introduction of #InvasiveSpecies🌱 Remove all mud, seeds, & plant materials between hikes. Boot brushes are a great tool for cleaning your shoes. Find a boot brush station at bit.ly/421Me5b. #4Good4GYE

In the excitement of getting outdoors, it's easy to forget that responsible recreation starts at home! Check your gear, pets, & equipment for any mud or organic materials that might be carrying invasive species. Learn more at stopais.org/GYE. #4Good4GYE #Yellowstone

Over the last few weeks, we had the chance to join Grow Wild and Gallatin River Task Force for some #CleanDrainDry outreach on the #GallatinRiver💦 Did you miss us? We'll also be at the Gallatin #Whitewater Festival on Saturday, June 28. Come say hi and grab some free goodies!

#PlayCleanGoWeek is almost over, but #ResponsibleRecreation is important all year long!🌷 How can you get involved? It's easy! Even the smallest actions can help protect our favorite places. What's your favorite way to prevent the spread of #InvasiveSpecies? Comment your answer!

Did you know that felt-soled waders/boots are prohibited in #Yellowstone NP as they pose a large risk of spreading #invasivespecies? If you're an angler, do your part to keep our waters pristine by practicing #CleanDrainDry. Learn more at stopais.org/GYE🎣💦 #4good4GYE

Are you visiting the GYE? Make sure you aren't packing #InvasiveSpecies. No matter what you float, remember to #CleanDrainDry every time & stop at #InspectionStations to protect our waters!🚣‍♂️💦 Learn more about how you can protect the #GYE at stopais.org/GYE. #4good4GYE

Today's #weed of the day is #houndstongue! Don't let the name fool you, it's bad news for pets, pastures, & livestock. What You Can Do: -Pull plants before they go to seed (wear gloves!) -Check your pets and gear after hiking -If you see it, call your local weed district #MNWAW

Today's #noxiousweed is dalmatian toadflax🌱 Don’t be fooled by the snapdragon-like blooms—#DalmatianToadflax is an aggressive invader. This perennial spreads fast & is tough to control. If you see it, report it! Let’s work together to keep Montana’s landscapes healthy. #MNWAW

It's MT #NoxiousWeed Awareness Week! Today's #weed of the day is #ventenata. It might look like just another grass—but it’s a troublemaker! It sneaks into fields, takes over, & makes it hard for natives to grow. Let’s protect our wild places & help the good grasses grow strong!

Next week is MT Noxious Weed Awareness Week! How can you celebrate? We encourage everyone to learn to identify & report infestations. You can also celebrate by: 🌾Organizing a #weedpull 🍃Reposting noxious weed information 🍀Talking about #noxiousweeds w/ friends & family #NWAW

Reporting invasive species is a very important part of protecting the GYE. Monitoring and reporting are critical parts of controlling invasives. Suspected invasives species should be reported to your state agencies or at inaturalist.org online or in the app! #4Good4GYE

Yesterday was National Day for Biodiversity! 🦋🌿 We often get asked about biodiversity in relation to invasive species. So, what is biodiversity? & how is it connected to invasive species? #FAQFriday #biodiversity #invasivespecies

Protect the waters you love & #CleanDrainDry🚣‍♀️ Clean boating applies to everyone on the water! No matter what you float, remember to CLEAN, DRAIN, DRY to protect our waters from invasive species for generations to come. Learn more at stopais.org/GYE. #4Good4GYE #GYE

Calling all Geocachers!🐛✨ ISAN launched several Travel Bugs in an effort to educate #geocachers about invasive #forestpests & their native lookalikes. Keep an eye out for these Travel Bugs while #geocaching! Learn more about invasive species at stopais.org.

We had an absolute blast at the 2025 Spokane Garden Expo!🌻 Thank you to everyone who stopped by and chatted with us about invasive forest pests. To protect our forests, always remember to report invasive species and #DontMoveFirewood. #GardenExpo #Spokane #InvasiveSpecies
