The Sea to Sky Invasive Species Council (SSISC) will be removing Cutleaf Blackberry, an invasive plant, on Lillooet Lake Road near the Main Street intersection between August 17 and August 20, 2020.
What is Cutleaf Blackberry? Cutleaf Blackberry is an invasive species that originates from Europe and thrives in a ride range of habitats such as disturbed areas, pastures, roadsides, riparian areas and wetland edges. It can spread vegetatively by rooting from the cane and seeds are spread due to birds and mammals eating the fruit and dispersing the seeds to new locations.
What are the impacts of Cutleaf Blackberry? Cutleaf Blackberry grows into impenetrable thickets and outcompetes native plants. This reduces biodiversity, degrades pastures, infests stream channels and banks, prevents the establishment of native trees, restricts access of wildlife to water, and increases the likelihood of erosion along riverbanks.
How will Cutleaf Blackberry be removed? Cutleaf Blackberry will be removed mechanically. This is done by cutting down the plant and then removing the roots.
