Beneficial Management Practices for Saskatchewan Species at Risk: Western Spiderwort Threatened • Plants 5-60 cm tall • Grass-like, alternate leaves 10-30 cm long • Clusters of up to 25 blue, rose or white flowers • 3 round petals Sarah Vinge • Perennial flowering late June to early July • Inhabits partially stabilized and active sand dunes • Prefers south and southwest facing slopes where snow is more abundant and sun exposure is greatest • Located in the Elbow Community Pasture and Douglas Provincial Park in the Elbow Sand Hills • Status: Threatened • Decline due to habitat loss to cropland (historical), dune stabilization, exclusion by invasive alien species, ATV use on dunes, sand and gravel extraction, road/right-ofway maintenance, and high intensity grazing • Most current SK estimate: ~48,700 plants Beneficial Management Practices Grazing • Graze moderately during late season • Graze every year but graze heavily in some to help destabilize dunes and reduce woody and other competing vegetation • Use methods that do not disturb native herbaceous ground cover when clearing brush to improve range or access Invasive Alien Plant Species • Avoid using herbicides in the vicinity of a Western Spiderwort population • Biological control of leafy spurge using insects may benefit Western Spiderwort • Seed non-invasive forages if seeding adjacent to Western Spiderwort site or consider using native forages Roads • Place any roads, trails and other developments away from known plants • Avoid use of existing roads and trails adjacent to spiderwort sites during growing season • Eradicate or control spread of invasive plant infestations along roads and trails adjacent to spiderwort sites
