    The Quadra Overpass Garry Oak Planting: 30 Year Remeasurement, Sept 2025.

    By Jacklyn Jolicoeur and Ryan Senechal

    The Commonwealth Games Legacy Garry Oaks 

    This was a legacy Garry oak tree planting project to commemorate the 1994 Commonwealth Games.  Two members of GOMPS -Jean-Anne Whitman, landscape architect and Willie MacGillivray, together with the Ministry of Transportation and Highways, the Provincial Capital Commission, Forestry Canada and a group of community volunteers, participated in this project.    

    Planting Technique and Seedling Source
    All of the planting techniques were arrived at through consultation with representatives of GOMPS, Forestry Canada and a project manager, Ms. Carol Jones, Professional Agrologist and Nursery operator in North Saanich at the time.  The intent was to use “the planting project to assess the growth and health of Garry oak seedlings and to evaluate the use of seedling protection tubes.”

    The site preparation included stripping, burying, and tilling the sod, blanketing the site with landscape cloth, and then covering it with bark mulch to keep weeds back.  As such, the site approximates a near-natural, non-irrigated habitat. 

    The Garry oak seedlings were “plugs” grown the year before (1993) by Rob Hagel of the Pacific Forestry Centre.  On February 19, 1994, volunteers planted 211 seedlings by inserting them into holes dug through the mulch and cloth with a tablet of Bestgro fertilizer placed into the bottom of each hole.  Approximately 80% of the seedlings were shielded with protective tubes.

    Previous Inspections 
    The planting clusters were inspected during March of 1994, April of 1995, and in October 1995.  The writers do not have access to the records for these inspections.  In the fall of 2005, Dr Michael Meagher (retired forester and honorary member of GOMPS) recorded some key measurements and statistics for the planting clusters in the GOMPS newsletter (June 2006), which form the basis of a comparison of the Garry oak trees in 2005 and 2025 (see table below).

    2025 Remeasurement 

    During September of 2025, two members of GOMPS (Ryan Senechal, President and Jacklyn Jolicoeur, Director visited the plantation site and recorded basic tree inventory statistics for all remaining survivors of the plantation into a mobile application.  The tree data collected included the GPS coordinates, DBH (diameter at breast height), tree height, tree condition, leaf condition, and tree comments.  Here is a comparison summary of the Garry oak tree data over the years.

    Some key takeaways from the assessment

    • Garry oaks require some protection and establishment care to minimize plant mortality.
    • Young tree mortality primarily occurred within the first 10 years of planting.
    • Canopy growth and ring growth rates are slow but faster than estimated in 2006 article).
    • Narrow spacing between Garry oak trees has a considerable effect on understory biodiversity.  These Garry oaks were planted at approximately 3.5 to 4 metres apart. Optimum spacing would be 10 metres.
      • Shrubs and herbaceous species were lacking in the understory.  Multiple stick nests were present, but the species occupying those nests could not be identified.
      • The trees were crowded and crowns overlapped.
    • Acorn collection should take the Garry oak tree form into consideration.  The majority of trees planted demonstrated similar branch architecture.  One defect that consistently appeared was forks with included bark. 

    Future Opportunities – Short Term

    • Resurrect a sign at the Quadra Interchange to acknowledge this legacy tree planting project 
    • Remeasurement of the McKenzie interchange that was also planted in 1994.
    • Introduce stand management to address weak branch unions, improve tree spacing and enhance understory biodiversity.

    Future Opportunities – Long Term

    • Resurrect the vision for the Ministry of Transport (MOT) to improve the local highway landscape with interagency cooperation amongst local governments, GOMPS and others in the volunteer environmental community.  This vision would  pursue enhancement to the large linear greenway along highways with Garry oak tree/meadow plantings to promote biodiversity, climate adapted natural vegetation and create improved driving experience.
    • Extend planting areas and incorporate companion species.  Improve access from Quadra St and incorporate seating.

    URBAN FOREST: CITY-WIDE

    Vancouver Island is located within the Coastal Douglas-fir biogeoclimatic zone. Human pressure from development, agriculture and logging make it the most at-risk biogeoclimatic zone in BC.

    The Kwetlal food system, colonially known as the Garry oak ecosystem, is a subcomponent of this zone and emerged after the glacial retreat around 10,000 years ago. According to the Canadian Forestry Service, the ecosystem is mostly contained to the Metro Victoria area in Canada.

    The open woodland character resulted from millennia of Lekwungen agroecological management and is considered to be a living artifact by the Lekwungen-speaking people. In the absence of these activities, the landscape would be dominated by closed stands of Douglas-fir and Grand fir.

    While relatively intact Garry oak ecosystems can be found in Regional Parks, 75% of Garry oak trees and modified ecosystems are located on what the municipality refers to as private land.

    The Garry oak tree, a long-lived keystone species, supports over 1,645 co-evolved species of plants, insects, mammals, amphibians, birds, and reptiles (that differ from wildland species), making its preservation crucial. Garry oak and associated ecosystems in this region have a unique local genetic adaption that would be difficult to re-introduce if lost.

    Trees exist on private properties in Victoria that exceed 250 years old—the marker which meets the definition of old growth for coastal forests by the Province of BC—and many of those old trees continue to thrive, vibrating with the rich cultural history of the Lekwungen territory.

    Naturally adapted to this region’s severe droughts and heat, native Garry oak trees serve as vital nature-based solutions to counteract flood risks and the urban heat island effect, particularly affecting vulnerable populations.

    Plant ecologist and Indigenous scholar Robin Wall Kimmerer, in her book Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge, and the Teachings of Plants, advocates for weaving together Indigenous wisdom and scientific knowledge to help mend the relationship between humans and the natural world.

    The City’s OCP Vision 2050 Reconciliation Actions, Understanding Indigenous Land and Water Management, states that the City will “seek to understand the practices that have supported ecosystem conservation for millennia and work collaboratively to braid Indigenous knowledge systems with Western science in preserving and enhancing natural assets, and in advancing a climate-forward city.”

    The City of Victoria Draft OCP City bylaws, legislation, and process undermine this objective.


    Key Issues

    • The OCP’s new land use class scheme was determined without a City-wide biodiversity assessment on private land, presenting an obstacle to stewardship opportunities.
    • Development Permit Areas for all new housing include requirements for protecting the natural environment, its ecosystem, and biological diversity; however, the General Urban Design guidelines for the urban forest were crafted in the absence of an Indigenous land manager, licensed ecologists, biologists, or urban foresters.
    • Tree Protection Bylaw (21-035) has not been updated since provincial housing legislation directives (2022) and cannot provide physical protection for existing trees located within a proposed building envelope.
    • We are encouraged that the canopy has grown by 100 soccer fields over 10 years while adding more than 8,000 net new homes (almost entirely multifamily buildings). However, the rate of growth dropped by 50% in the last four years, meaning 23 hectares short of the previous four years’ urban tree canopy growth rate.


    Proposed Urban Forest Policy Recommendations

    • Adopt a City-wide Garry oak species detection tool as part of ongoing urban forest remote sensing updates.
    • Create an Urban Forest Technical Advisory group as recommended by the City of Victoria’s Urban Forest Master Plan (2012), with representation from Indigenous knowledge systems, environmental organizations, ecologists, biologists, and urban forestry experts to analyze government and third-party data (such as urban forest remote sensing) and report their recommendations to Parks + Urban Forestry.
    • The OCP reduced Landscape Area (Plantable space) minimums from 9% to 6% on every development lot. Plantable space is a leading indicator of canopy coverage.
    • Therefore, increase the Landscape Area (Plantable space) minimums in Priority Growth and Residential Infill Zoning Areas from 6% to 9%.
    • A 6 m backyard setback (for example) provides limited opportunity to retain existing large trees, and the “Minimum Required Trees Per Lot” is excessively difficult to achieve when applying spacing requirements in the Tree Protection Bylaw.
    • Therefore, increase all setbacks by a minimum of 2 m for Landscape Area (Plantable space) (i.e., soil area for planting a large species of tree as opposed to a medium-sized tree) in the Priority Growth and Residential Infill Zoning Areas.
    • Update Section (4) Applied Guidelines (Pages 189, 193, etc.) from “INTACT Garry oak ecosystems” to “and modified Garry oak ecosystems and Garry oak trees.”

  • Improvement for GOMPS Garry Oak Volunteer Nursery From Nature-based Climate Action Grant – Victoria Foundation

    Improvement for GOMPS Garry Oak Volunteer Nursery From Nature-based Climate Action Grant – Victoria Foundation

    In 2023 GOMPS applied for a Nature-based Climate Action Grant administered by the Victoria Foundation for key infrastructure and maintenance investments for sustainability of the GOMPS Garry Oak Volunteer Nursery.

    In 2024 GOMPS received a $13,000 grant to assist with Nursery costs including the erection of a secure and safe work shelter for nursery volunteers having lost 2 previous shelters due to wind, snow & storm damage.

    GOMPS thanks Volunteer Susan Grant who researched shelters, arranged & supervised installation of the shelter and Volunteer Marion Nyberg for making the shelter’s accesses safe for volunteers & visitors.

    The latest Nursery shelter made it through its first winter enabling volunteers to better enjoy the workparties at the Volunteer Nursery!
