CHEMICAL REMOVAL OF HIMALAYAN BLACKBERRY (RUBUS ARMENIACUS) IN DERBY REACH REGIONAL PARK, LANGLEY, BC

  • Alison Martin University of Victoria

Abstract

Invasive species are recognized globally as the second greatest threat to biodiversity after direct habitat
loss (British Columbia Ministry of Environment, 2018). Throughout Metro Vancouver, many restoration
projects are being implemented to control invasive species and restoring the natural vegetation that were
once there. Sierra Harvey and I partnered with Metro Vancouver Regional Parks to provide
recommendations regarding the removal of Himalayan blackberry (Rubus armeniacus) at Derby Reach
Regional Park in Langley, British Columbia. The goal is to remove the Himalayan blackberry and plant
native species to encourage the return of overwintering birds and pollinators. Sierra and I conducted
multiple field visits to create a biophysical inventory of the site. This project, we outlined two types of
removal techniques for Himalayan blackberry and have divided the work in such a way. I will be focusing
on the chemical removal method and will provide recommendations for this method as well as on timing
and methods of application to minimize environmental impacts. Sierra Harvey’s project will focus on the
mechanical techniques and provide recommendations for this technique at the site. As well, follow up
restoration activities such as a list of native species to be planted, a monitoring and maintenance plan, is
provided.
