Inventory, Control & Monitoring

Invasive Species Management

The core of our invasive species management work is carried out in the late spring and summer months. SSISC relies on public eyes on the ground to help report sightings.
Early Detection and Rapid Response (EDRR) – the process undertaken to find and eradicate a new incursion or infestation of an invasive species in the early stages of establishment when it is still relatively easy to control – has been very successful in helping to stop the spread early on. If you spot an invasive species, please report the sighting. Statistics on inventory and control work are gathered throughout the season and reported to funders each fall.

The Sea to Sky Invasive Species Council’s Field Crew manages invasives by carrying out:

Inventory  |  Manual Control   |  Chemical Control   |  Monitoring

The SSISC crews are available for hire, please contact us at  info@ssisc.ca to find out more about our fee-for-service program.

Landscape scale invasive species management requires cooperation and funding from many and varied stakeholders. See links below for examples of projects where SSISC and stakeholders are working together to achieve invasive species control and habitat restoration.

Inventory

The first step in any invasive species management plan is to complete an inventory. Knowing what invasive species exist and where they are located are essential when setting priorities for taking action. Initial inventory in the Sea to Sky Corridor took place in 2010 with funding from the provincial and federal governments’ Hot Spots program. All invasive species inventory collection across British Columbia is submitted to a public database – the Invasive Alien Plant Program (IAPP).

 

 

 

 

 

Manual Control

Manual control of invasive species

Where possible and feasible, control work is done manually. Manual control strategies include pulling, cutting, digging, mowing and excavating. To learn about control strategies for different species see our SSISC’s Guide to Identification & Management and species specific Factsheets.

 

Chemical Control

Chemical control of invasive species

Extremely aggressive and destructive invasives, such as Japanese knotweed, require chemical control as it is the only effective method of management and eradication.

Chemical control options include stem injection, cut and fill, and backpack foliar spray. All chemical control work done by SSISC is completed by Certified Pesticide Applicators. SSISC offers Best Practices Field Training for Herbicide Applicators upon request.

When does the risk of an invasive species causing detrimental impact on human safety, environmental health and the economy outweigh the risk from potential herbicide contamination? As a society we need to weigh all of the risks and develop  best management practices.

On Crown Land SSISC follows all protocols set out in the Pest Management Plan for the South Coast Mainland.

Monitoring

Invasive species management is a multi-year process requiring an integrated approach. Complete eradication of an invasive species infestation typically does not occur after the first year of manual or chemical control, due to a number of factors. A long lasting seed bank in the soil, the ability to regrow from a small section of stem or root, and resistance to herbicide are just a few ways that invasives demonstrate resilience to control efforts. Not all control efforts are equally effective. For this reason, SSISC monitors control efforts following provincial standards and enters data into the Invasive Alien Plant Program (IAPP) database. This allows SSISC to assess the progress and effectiveness of control efforts in our region. The information is then used during future decision making in order to maximize efficacy of future control efforts.

SSISC also carries out monitoring for biocontrol agents. To find out more about the Province of BC’s BioControl Program, please refer to the Biocontrol Program Website.
