Annual Gros Ventre River Spray Days

map

Every year since 2004, members of the JHWMA join forces in July to treat spotted knapweed along the Gros Ventre River. We start where the infestation begins in the Bridger Teton National Forest and follow it 11 miles to the Snake River. In the earlier years of the project, only portions of the river were treated due to the dense growth of the knapweed. After many years, the infestation is noticably less dense, allowing us to treat the entire corridor. Spotted knapweed seeds are known to be viable for at least 8 years and each plant can drop over 1,000 seeds per year. We still have a long way to go.

    4th Grade JHWMA Wildlife Expo


    map

    Wednesday, May 1st, 2013 the Jackson Hole Weed Management Association (JHWMA) held its 10th Annual JHWMA Wildlife Expo, for Teton County 4th graders. Approximately, 200 students from around the valley arrived at the Jackson Hole & Greater Yellowstone Visitors Center to learn about this year’s theme, “The Only Constant is Change” by JHWMA member agencies. The day kicked off outside with an explanation of who the JHWMA is and how local agencies and land managers work together to control noxious weeds across all jurisdictional boundaries throughout the valley.

    Students rotated through six -13 minute stations. Station 1: Game & Fish – Aquatic Invasives, Station 2: Teton Science School- Water Ecology, Station 3: Grand Teton National Park – “Bearly” in Time: Rescuing Endangered Species, Station 4: Bridger Teton National Forest – Fire and the Changing Landscape, Station 5: WY Ag in the Classroom – How to use Beef, and Station 6: JH Conservation Alliance- Wild Neighborhoods.

    After the stations, students gathered outside to review the main points of each station. Agency members donated over 25 items that were away as prizes. Students who answered questions correctly won hats, shirts, books and other fun stuff. Goody bags were also given out to each student full of information, activity books, pencils, stickers, and more.

    Thanks to the JHWMA members, the visitors center for hosting, and the school teachers for making this year another success!
