JACKSON, Wyo. — For the third year now, Jackson Hole Weed Management Association (JHWMA), Teton County Weed and Pest (TCWP) and Working Dogs for Conservation (WD4C) have teamed up to locate invasive species along the Snake River.
Since 2002, JHWMA and TCWP have conducted an Early Detection and Rapid Response (EDRR) program on the Snake River to locate, remove and eradicate saltcedar and perennial pepperweed (Lepidium latifolium). These species grow in dense stands, block access for wildlife and recreation and change soil nutrient loads which create ideal conditions for their growth while limiting the growth of other species.
Saltcedar was first found on the Upper Snake River in 2001, leading to the beginnings of the Snake River Project in 2002. Saltcedar and perennial pepperweed, which is also an EDRR species on the Snake River, are both aggressive invaders of riparian areas.
These teams continue to find saltcedar plant and nearly a dozen perennial pepperweed plants each year indicating that there is a seed source that is being missed by human teams.
WD4C started scent training canine teams in 2020. Over the last two years, these teams found an additional 48 perennial pepperweed locations on the Snake River between Moose and Wilson, roughly 40% more than human teams.
Canine teams will be on the islands on the river starting today through Wednesday, Aug. 31.
