New locations of Wild Parsnip (an invasive species) have been reported along Lillooet Lake Road. The Sea to Sky Invasive Species Council (SSISC) will be surveying this area for Wild Parsnip on Thursday, August 8. Plants will be hand pulled at this time and large infestations will require herbicide treatment in September. Herbicide will not be used in areas close to the river.
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 in multiple locations along Lillooet Lake Road. This is the only area Wild Parsnip has been found within the Sea to Sky corridor and this is one of a small number of sites within BC. Eradication is a high priority.
