Article #32 of 50 – Municipal Planning Perspective

Introduction

The City of Colwood, like many municipalities on Vancouver Island, is mandated under the British Columbia Invasive Species Act (ISA) and local bylaws to control the spread of invasive flora that threaten native ecosystems, public safety, and municipal infrastructure. Himalayan blackberry (Rubus armeniacus) ranks among the most problematic species due to its rapid vegetative spread, dense thickets, and propensity to out‑compete native vegetation.

Ascent Yard Care, operating since 2017 under the professional oversight of Certified Arborist Jake Innes, provides Himalayan blackberry removal services in Colwood that align with municipal policy, provincial regulations, and best‑practice ecological standards. This blog post outlines the regulatory context, our systematic eradication methodology, and actionable guidance for property owners seeking compliance‑driven weed control.

1. Regulatory Context for Invasive Plant Management in Colwood

Regulation	Relevance to Himalayan Blackberry
Invasive Species Act (ISA), R.S.B.C. 1996	Requires landowners and municipalities to prevent the establishment, spread, and impact of designated invasive species, including Rubus armeniacus.
Colwood Bylaw No. 2020‑03 – Invasive Plant Control	Mandates timely removal of invasive plants on private and public lands; imposes penalties for non‑compliance after a 30‑day notice.
Municipal Green Infrastructure Guidelines	Emphasizes environmentally‑sound herbicide use, protection of adjacent native habitats, and monitoring of treatment efficacy.
WorkSafeBC (WCB) Safety Standards	Governs safe handling of herbicides, personal protective equipment (PPE), and training for all field personnel.
Insurance Requirements	Five‑million‑dollar liability coverage and WCB coverage are mandatory for contractors performing invasive plant work on municipal lands.

Ascent Yard Care meets or exceeds each of these statutory requirements. Our five‑million‑dollar liability insurance and WCB‑compliant workforce ensure that all operations are legally protected and safely executed.

2. Scientific Basis of Our Himalayan Blackberry Eradication Protocol

2.1 Targeted Herbicide Application

Active Ingredient: Glyphosate (Roundup®) formulated at 2 % concentration, the concentration recommended by the Ministry of Environment for woody invasive species.
Mode of Action: Systemic translocation to roots and rhizomes, guaranteeing complete die‑back.
Eco‑Friendly Safeguards: Application is executed during the early‑season growth phase (April–May) when native flora are dormant, minimizing non‑target impact.

2.2 Integrated Mechanical Removal

Root Excavation: For dense thickets, we employ hand‑tools and low‑impact mechanical diggers to sever root crowns, reducing regrowth potential.
Mulching & Disposal: All plant material is double‑bagged and disposed of in accordance with BC Waste Management Regulations, preventing inadvertent seed spread.

2.3 Monitoring & Guarantee

30‑Day Effectiveness Guarantee: If any Himalayan blackberry shoots remain viable after 30 days, a second treatment is provided at no additional cost.
Documentation: We submit a post‑treatment report to the property owner and, upon request, to the City of Colwood’s Environmental Services Department, satisfying regulatory record‑keeping.

3. Local Insights: Himalayan Blackberry in Colwood

Colwood’s coastal temperate rainforest microclimate—characterized by mild, wet winters and moderate summer temperatures—creates ideal conditions for Rubus armeniacus to proliferate along park edges, utility corridors, and residential lot boundaries.

Hotspot Areas: The West Bay Trail, Garry Point Park, and East Sooke Road have documented infestations that interfere with trail accessibility and fire‑break integrity.
Ecological Impact: Dense blackberry thickets suppress understory growth of native species such as Salal (Gaultheria shallon) and Red‑cedar (Thuja plicata), reducing biodiversity and habitat quality for local fauna (e.g., Belted Kingfisher, Pacific Tree Frog).

Municipal planners advise property owners to report new infestations to the City’s Invasive Species Hotline and to schedule professional removal within 14 days of detection to avoid breach of bylaw 2020‑03.

4. Step‑by‑Step Process for Homeowners

Step	Action	Compliance Note
1. Site Assessment	Certified Arborist Jake Innes conducts an on‑site survey to map infestation density and identify protected native species.	Aligns with ISA requirement for “assessment of impact.”
2. Permit Verification	Review of any required municipal permits (e.g., for work near watercourses).	Ensures adherence to City of Colwood bylaws.
3. Treatment Planning	Development of a Site‑Specific Management Plan (SSMP) outlining herbicide dosage, timing, and mechanical methods.	Provides documented evidence for audit.
4. Execution	Targeted herbicide application and mechanical removal performed by WCB‑trained crew.	Meets WorkSafeBC safety standards.
5. Post‑Treatment Monitoring	30‑day site inspection; any surviving shoots trigger free second treatment.	Satisfies the City’s “effectiveness guarantee.”
6. Reporting	Delivery of a compliance report, including before‑and‑after photos, to the homeowner and optionally to municipal authorities.	Completes regulatory documentation.

5. Why Municipalities Trust Ascent Yard Care

Track Record: Trusted by The City of Victoria and The City of Langley for large‑scale invasive plant eradication projects, including municipal park restorations and utility corridor maintenance.

6. Practical Tips for Colwood Residents

Early Detection: Conduct quarterly visual inspections of property perimeters, especially after the rainy season (October–December).
Avoid DIY Spraying: Improper herbicide dilution can violate the ISA and cause collateral damage to native flora and pollinators.
Maintain Buffer Zones: After removal, install native groundcovers (e.g., Kinnikinnick, Oregon grape) to suppress re‑colonization.
Report to City: Use the Colwood Invasive Species Hotline to notify authorities of large infestations; this can trigger municipal assistance.
Document Everything: Keep records of removal dates, treatment methods, and photos for municipal compliance audits.
