The Sea to Sky Invasive Species Council (SSISC) will be removing invasive plants (Wild Parsnip) on Lillooet Lake Road and adjacent residential properties between May 27 and June 15, 2019.

What is Wild Parsnip? Wild Parsnip is an invasive species that contains a highly toxic sap that can cause severe burns and blindness if it comes into contact with the skin or eyes.  It grows quickly and forms dense stands, especially in disturbed and abandoned agricultural areas.  One plant can produce an average of 975 seeds that can be viable for up to 5 years.  Wild Parsnip is highly competitive and will continue to spread and outcompete native vegetation if not removed.

Where has Wild Parsnip been found?  Wild Parsnip has been found approximately 2.3 km down Lillooet Lake Road on the southern side and the adjacent residential properties.  This is currently the only known Wild Parsnip site within the Sea to Sky corridor and eradication is a high priority.

Identification of Wild Parsnip:  Wild Parsnip can grow up to 1.5 metres tall.  It has very small, yellow-green flowers in umbrella-shaped clusters that bloom from May to September.  Its leaves are alternately arranged on stems with mitten-shaped and toothed leaflets, and its stem is light green and deeply grooved.  If you suspect you have Wild Parsnip or any other invasive species growing on your property, please submit a report to SSISC at 604-698-8334 or

Wild Parsnip Removal:  Because of Wild Parsnip’s toxic nature, its dense, established plant stands and large seed bank, mechanical removal of the plant is not feasible and the SSISC has carefully selected an herbicide to remove it.  SSISC staff are highly trained, certified pesticide applicators who observe pesticide-free zones around bodies of water and follow standard protocols that dictate the conditions in which herbicide can be sprayed.  The use of this herbicide requires a 10-metre buffer from any waterbody. In this case, there will be a 20-metre buffer between the river and the application site.  The plants will be carefully sprayed directly, close to the ground, and during low winds to minimize any herbicide drift.  The herbicide used will not impact the grasses on site and the SSISC will also be reseeding the area with native vegetation to encourage the growth of native plants.

Post-Treatment Protocol:  Treatment sites will have signage posted for two weeks following treatments; please avoid touching the plants during this period.  There are no restrictions to people or animals entering this area after the two-week period has passed.
