In what Ecoregion / Ecosection is Race Rocks Ecological Reserve ?

January 31 2024 is the deadline for public submission of comments on The Draft Framework on Bodiversity and Ecosystem Health

For an understanding of the differences in the many ecosystems in British Columbia and an appreciation of where Race Rocks Ecological Reserve fits in the classification, I have found this good description of Ecoregions and Ecosystems which includes a reference to Race Rocks, and the small percentage of the Ecosection in which it lies that is protected. 

The Evergreen Alliance has produced an important document detailing the current state of protected areas in British Columbia. In the BC Government’s new emphasis on the value of preserving Biodiversity and Ecosystem Integrity, it is interesting to note what percent of various ecoregions of British Columbia are in need of protection to meet the 30X30 goal . 

GPB Ecoregion

The Georgia Puget-basin Ecoregion

From:  An Introduction to the Ecoregions of British Columbia

In the OVERVIEW, There is a good definition of Ecosections:

“The Ecoregion Classification System was first adopted by the Ministry of Environment in 1985 to serve as a framework for recognizing small scale ecosystems in British Columbia. The Ecoregion Classification helps us to understand and to depict the great habitat diversity of the province. Since 1985, the Ecoregion Classification has been revised five times to reflect more detailed mapping. The fourth revision Ecoregion units was mapped at 1:250,000 using Landsat, topographic, Biogeoclimatic and marine ecosystem information, while the fifth revision has been mapped based on the earlier concepts plus detailed vegetation zonation mapping. The most current digital (GIS) database is Version 2.1 2006, but the supporting reports and descriptions is the third edition 2011. The Ecoregion Classification system is used to stratify British Columbia’s terrestrial and marine ecosystem complexity into discrete geographical units at five levels. The two highest levels, Ecodomains and Ecodivisions, are very broad and place British Columbia globally. The three lowest levels, Ecoprovinces, Ecoregions and Ecosections are progressively more detailed and narrow in scope and relate segments of the Province to one another. They describe areas of similar climate, physiography, oceanography, hydrology, vegetation and wildlife potential. Within each terrestrial ecoregion, climatic zones occur where specific soils, plant and animal communities and aquatic systems develop because of the interaction of climate with the land surface and surficial materials. These zones are best defined within the Biogeoclimatic Ecosystem Classification system. Ecological zones in marine ecosystems are products of temperature, salinity, sea-bed configuration and water depth. The Marine Ecoregion Classification system should be used to define the marine ecosystems. Each ecosystem is ultimately identified by sampling individual sites. At the lowest level in an ecosystem classification, attention is directed to specific parameters, such as topography, surficial materials, soil development, moisture regime, microclimate, floristics, succession, productivity and animal use. Ecoregions should be thought of as ‘big picture’ ecosystems. As such the province should be viewed first for its big, all-inclusive landscape chunks, then progressively through more detailed levels, and finally each area of the province has to be viewed with other classifications or the underlying geographical detail. The boundaries between units must be thought of in the same way, broad lines for small scale ecosystems progressing to greater precision for the larger scale ecosystems. For convenience, however, one boundary is used to define all ecosystem levels, from Ecodomain down through to the Biogeoclimatic or marine unit level……….

Ecoprovince Subdivisions
From page 47: The Georgia Depression Ecoprovince in British Columbia is subdivided into four ecoregions containing seven ecosections (One of those is a marine ecoregion and three are marine ecosections)…………

on page 53 there is a description of the GEB – Georgia Basin Marine Ecoregion: In British Columbia this marine ecoregion contains two marine ecosections.

GEB – Georgia Basin Marine Ecoregion: In British Columbia this marine ecoregion contains two marine ecosections. o SOG – Strait of Georgia Marine Ecosection: This is a broad relatively shallow, semienclosed estuarine basin that separates southern Vancouver Island from the mainland. It is mainly marine waters, but it also contains several islands. The islands have very dry mild climates, such as southern Quadra, Cortes, Texada, Lasqueti, Denman and Hornby islands. The southern islands and lower portion of Texada Island area dominated by the dry Coastal Douglas-fir Zone, whereas the northern islands and the upper portion of An Introduction to the Ecoregions of British Columbia 54 Texada Island are dominated by the very dry maritime variant of the Coastal Western Hemlock Zone. The marine environment is dominated by the intertidal, nearshore, epipelagic and mesopelagic zones. 

JOS – Strait of Juan de Fuca Marine Ecosection: This a deep trough marine area with a strong “estuary-like” outflow current. It is the major water exchange conduit between the Georgia – Puget Basin Ecoregion and the open Pacific Ocean. Except for a few islets, such as Race Rocks, most of the ecosection is marine waters. The northern and southern boundaries approximate the outer limit of the nearshore zone; while the eastern boundary in British Columbia is south of Chain Islets & Discovery Island; in Washington it is south of the San Juan Islands and east of Whidbey Island. The southern deep-sea marine portion of Pacific Rim National Park – West Coast Trail Unit occurs in the far northwest portion of this ecosection. ” 

In the Juan de Fuca Strait Ecosection there is .01 %  of the protected areas in BC,  and 5.57 percentage of the area is protected.

Wild Goose Chase

Weather & Sea Conditions

At dawn, the west wind was already blowing 30 knots and gusting. Although it dropped to 20 – 25 knots at times, the west wind continued to bring dramatic clouds and showers along with brief glimpses of sunshine and rainbows, throughout the day. The marine forecasters call for the wind to back to southwest and they estimate that the SW wind will diminish to 10 -15 knots, late overnight and drop to light, early Tuesday morning. Showers and the mix of sun and cloud are predicted to continue. Seas were rough today to the west and out in the Strait, while the entrance to Pedder Bay and the eastern horizon remained a little calmer in the lee.

Vessels

No vessels were observed in the protected area or passing nearby, today.

Ecological and General Observations

Canada Geese are more and more insistent that they belong on Great Race and two pairs are actively nesting now. Even if the eco-guardian were to spend 24/7 chasing off geese, it would be ineffective as they are incredibly persistent, very strong and have a certain goose cunning that harkens back beyond the etymology of ‘wild goose chase’. Without the large numbers of geese that were present last year and the crushing effects of dozens elephant seal dozers, the grass does appear to remain a little longer, but then it has been a wet spring.

Beulah, the large female Norther Elephant Seal staying in the garden, went for a dip this morning and on her return she seemed to enjoy ‘frolicking’ in the long grass, head down undulating through the greenery. She also found a clean place to sleep, next to an old, lighthouse heritage, rockery bed. After watching the elephant seals purposefully destroy the tulips last year, I picked a bouquet when she moved into that part of the garden and they are brightening my world on the little desk in the house.

More and more adult male California Sea Lions are hauling out on Great Race, This afternoon there were ~50 on the south side and a dozen more on the west side. Younger animals and Steller’s continue to haul on South Rocks. Yesterday evening, I discovered a new (to me) den for the old, male River Otter. I knew that there was an otter spot nearby due to the telltale ‘calling cards’ left outside the den area but it took a while to find it. He is barely visible and very protected, sleeping under one of the big boulders just northeast of the compost.

The Bald Eagles continue to spend the day in the Ecological Reserve; most active early and late, chasing gulls. There is a lot of evidence of piscivory on the island, but some of the remnants are hard to pin on any particular predator. The gulls here eat a lot of small forage fish like herring and marine invertebrates like chitons but there are also remains that look more like either River Otter or Bald Eagle leftovers (see images).

A Turkey Vulture stopped and rested near camera 5 today. I was hooked up to a staff meeting by conference call or I would have gone outside to photograph it. I did get a photo through the window, before it was swept away by the west wind. Black Turnstones continue to be present in high numbers, resting and fattening up before their northward migration.

Chores & Visitors

Chores today were routine and there were no visitors.

Conservation Message

If you are a commercial boater or if you use docks and harbours, you may be interested in two really excellent booklets on Green Boating and Displacement Hull Fuel Efficiency put together by the T. Buck Suzuki Environmental Foundation. Their Green Boating Guide covers good marine practices in seven main areas: wildlife protection, habitat protection, waste discharge, fluid handling, solid waste, fuel efficiency, and cleaners. The Fuel Efficiency Guide covers ways to reduce fuel consumption through both operational and design measures. Another way to look at savings on fuel is that it also reduces carbon dioxide pollution to the atmosphere. CO2 is not only a greenhouse gas, ~ 40% of it ends up in the ocean causing the shift in basic chemistry which is called ocean acidification, global warming’s evil twin.

There is a real shift in attitude happening amongst boaters of all types, as more and more people realize that we have to profoundly change our basic routines and behaviours in order to have a sustainable ‘blue’ future. I call it investing in green and keeping it clean for a blue economy. If you use social media please use the hashtag #green4blue to connect with other people going green for a blue future. Check out the booklets here for great ideas on how you can make a positive difference on the water.
