This highly specialized animal requires sandy shorelines in which to lay their eggs, the same soils that spotted knapweed and other invasive plant species inhabit

Invasive plant species can degrade nesting beds and result in direct mortality to developing hatchlings through root penetration into eggs and hatchling entanglement. This has been recently observed first hand near Argenta and Cranbrook. The picture to the left illustrates the root penetration and hatchling entanglement that can occur from spotted knapweed infestations. To learn more about the western painted turtle and knapweed entanglement see the Fish and Wildlife Compensation Program Current Newsletter.
