Why is at risk?

Loss of habitat is the main factor of why the Western Spiderwort's population is declining. Another factor of why it is declining is because of petroleum exploration and extraction in Manitoba. Excessive vegetation causes an unsuitable habitat for the Western Spiderwort as it causes shading and stabilizes the slope of the dunes. Another threat to the Western Spiderwort is high levels of grazing cattle which can disturb the vegetation and their habitat.
