This detection is the first in Teton County, WY and the third detection in the state (Sublette and Park).
Mark Daluge our Landowner Program Coordinator, has recently found an infestation of what we are confident is Austrian Fieldcress. This detection is the first in Teton County, WY and the third detection in the state (Sublette and Park). While we can’t be completely confident how Austrian fieldcress became introduced, we speculate that it was likely brought either in material used to construct a berm or potentially contaminated equipment. It appears to be spreading both by seed and aggressive lateral root creep. Since finding this primary infestation we have located one satellite infestation along a county road that sees relatively high traffic.
