Race Rocks Ecological Reserve Proposed as a KBA – Key biodiversity area

Posted on by

In June 2023 Ian Adams presented for the Annual General Meeting of Friends of Ecological Reserves on the Key Biodiversity Areas program in Canada.  This presentation is available here: https://ecoreserves.bc.ca/2023/06/07/key-biodiversity-areas-ian-adams-fer-agm-june-2023/

The website of KBA Canada is here: https://gis.natureserve.ca/portal/apps/dashboards/8a89d50ea0b04c7790e19791ab9ae6e8


Race Rocks Ecological Reserve is on the list of proposed KBAs in British Columbia along with several other Ecological Reserves in the province .

Summary of Proposed KBA
Please note that this summary was generated automatically, and as a result there may be species scientific names that are not italicized.
KBA Name: XwaYeN (Race Rocks)

Location (province or territory [mid-point lat/long]): British Columbia [48.297 /-123.53]
KBA Scope: National

Proposal Development Lead: Ian Adams
1.
5. Trigger Biodiversity Element(s):
● Species: Northern Elephant Seal (Mirounga angustirostris)
6. Site Status Summary:
XwaYeN (Race Rocks)
is a candidate National
KBA for the following KBA criteria:
● National D1a [criterion met by 1 taxon] – Site predictably holds an aggregation representing ≥1% of the national population size of a taxon,
over a season, and during one or more key stages of its life cycle (Mirounga angustirostris).
● National D1b [criterion met by 1 taxon] – Site predictably holds a number of mature individuals that ranks the site among the largest 10
aggregations known for the taxon in the country (Mirounga angustirostris).
7. Site Description:
The XwaYeN (Race Rocks) KBA overlaps with Race Rocks Ecological Reserve, which was created to protect intertidal and subtidal communities
that are extremely rich as a result of strong tidal currents. Energy and nutrient inputs attributable to the nearly continuous currents are large,
and light penetration in these shallow, clear waters is excellent. These factors result in a high production of algae and invertebrates, while the
varied topography promotes ecological diversity. Consequently, the marine communities here are unusually luxuriant and rich. XwaYeN is in the
Coastal Douglas-fir Moist Maritime biogeoclimatic zone (BC Parks 2022), though none of the islands are forested.

1 Meets criterion D1b because it is one of 10 largest aggregations in Canada for this taxon.

2 Composition of 10 Reproductive Units (RUs): Elephant seals are polygynous so 10 RUs is 10 adults females and 1 adult male. . Source of RU
data: IUCN 2016; Fletcher 2016; Race Rocks Ecoguardians 2022.

3 Derivation of site estimate: Other. Explanation of site estimate(s): Five Elephant seal pups were born at the site in 2021 (Race Rock
Ecoguardians 2022; BCCDC 2022). Race Rock Ecoguardian observation data collated for 1 Jan 2014 through 20 Jan 2016 found almost continual
presence of Northern Elephant Seal at Race Rocks. Counts range from 1 to 34 individuals, including all age classes: adults, sub-adults and pups.
A best estimate of 5 individuals is an approximate average during this time. Source(s) of site estimate(s): Race Rock Ecoguardians 2022;
Fletcher 2016; BCCDC 2022.

4 Explanation of national estimate(s): Five Elephant seal pups were born at the site in 2021 (Race Rock Ecoguardians 2022; BCCDC 2022). Race
Rock Ecoguardian observation data collated for 1 Jan 2014 through 20 Jan 2016 found almost continual presence of Northern Elephant Seal at Race Rocks. Counts range from 1 to 34 individuals, including all age classes: adults, sub-adults and pups. A best estimate of 5 individuals is an approximate average during this time. Source(s) of national estimate(s): BCCDC 2022; Race Rock Ecoguardians 2022; Fletcher 2016.

*The threat status displayed is the one that qualifies the species as a criterion A1 trigger under KBA rules, if applicable. Other statuses may exist.

9. Assessment Details – KBA Trigger Ecosystems: None
10. Delineation Rationale:
The ecological reserve boundary was followed due to the presence of rich intertidal and subtidal invertebrates that are not well documented as potential KBA eligible species. This also facilitates management options for the KBA.

12. Additional Site Information:
Rationale for site nomination XwaYeN (Race Rocks) KBA is the only Northern Elephant Seal rookery in Canada. As such, it meets criteria as a national D1a and D1b KBA.

Additional biodiversity at the site A unique hydroid, Rhysia fletcheri, was described as a new species from this site (Brinckmann- Voss et al. 1993), but its abundance and range extent are unclear. Several bird species stop over at the rocks during migration,Including Red Knot (Calidris canutus roselaarim, COSEWIC. Threatened). There are nesting colonies for seabirds including Pigeon Guillemot (Cepphus columba), Black Oystercatcher (Haematopus bachmani) and Glaucous-winged Gull (Larus glaucescens). Brandt's Cormorants (Urile penicillatus) occur at the site but do not nest there.
Both Steller (Eumetopias jubatus, COSEWIC Special Concern) and California (Zalophus
californianus) sea lions use Race Rocks as a winter haul-out. Quillback rockfish (Sebastes
maliger, COSEWIC Threatened) are present and partially protected by a Rockfish Conservation Area (FAOC 2021, see Site Management). Plants including Sea Thrift (Armeria maritima) and Tracy’s Romanzoffia (Romanzoffia tracyi) are present. Rare lichens are present such as Orange Sea Lichen (Flavoplaca marina – previously called Caloplaca marina) and a Grey Lichen (Myriolecis straminea – previously called Lecanora straminea). Iceland Gull (Larus glaucoides) can be found in large numbers and will likely be added as a contributing species in the future.
A full list of species observed at the site is available at https://racerocks.ca/race-rocks-animals-plants/taxonomy-image-gallery/

Customary jurisdiction at site

Traditional territories of the Sc’ianew First Nation, Esquimalt First Nation, and T’Sou-ke First
Nation. Á,LEṈENEȻ ȽTE (W̱SÁNEĆ); Te’mexw Treaty Association; Douglas Treaty may include

In Memoriam : Pam Birley

Posted on by

For many years we had the privilege of having many contributions to the Race Rocks website by Pam Birley of Leicestershire, England. Pam was a regular observer on our remote-controlled cameras, and she made the most observations of any outside viewer on the website. For 10 years, from 2004 to 2013, she produced a monthly set of images, which we consider to be  a most valuable baseline record of the animal life at the ecological reserve during those years,  https://racerocks.ca/pam-birleys-images-of-race-rocks-2004-2013/

Clicking on   https://racerocks.ca/?s=Pam+Birley&submit=Search illustrates how prolific Pam was in reporting on unique as well as regular events at Race Rocks Ecological Reserve.  In 2005 and 2008  we were able to accompany Pam and her husband Dennis on trips to Race Rocks. She loved keeping track of activities of the sea birds and marine mammals and several times she was the first to report the birth of an elephant seal pup early in the year. We also mused that if a shingle was loose on a roof of one of the buildings, Pam would be the first to let us know. 

We are so sad to hear recently of her passing and we will miss her contributions greatly 

Unfortunate sighting

Posted on by

Infractions:

As I was sitting on top of the engine room next to the solar panels as I had spotted orcas in the distance.
All of a sudden I see a motor boat that approaches the reserve and slows down as it should.  Nothing unusual here… Until an adult an a couple kids carefully make their way to the bow (front) of the boat and sit down.

I then see the power boat get closer and closer to one of the outer rocks in the reserve… passing over the kelp bed and getting exceptionally close to the sea lions.
I then try and contact the vessel on both channel 68 and 16 with no response.
The vessel kept approaching the animals, without much surprise this boater makes the entirety of the island stampede and escape into the water, causing big disruption to the animals.

Unluckily for this Sunday boater I had a 400mm telephoto lens with and a pair of binoculars sitting on my lap…

What an example to set for the kids sitting on the bow :(.
I always wonder if these people are aware of the ecological impact of their actions or if they simply don’t care.

Facility Work:
Improvement of Electric fence system
Cleaning of solar panels (daily)
Cleaning of windows (almost daily)
Clearing remainder of scrap wood.

A Wild Gull Chase

Posted on by

Today (Thursday) is my last full day as a relief Eco-guardian at Race Rocks, so it seemed fitting that there be a few interesting events. The first was waking up to a sky full of wildfire smoke. We’ve been so lucky with the westerly winds that kept all of the smoke away, but with the latest heat wave and drop in wind, it was on us before dawn today.

Smoke on the water

It was also eerily quiet.  The hundreds of California Gulls that have been somewhere around here each morning were missing.  What was present were tankers and bulk carriers. I’m sure they’ve been plying the waters of the shipping channel all week, but today was the first day I noticed them in such numbers.  There were 6 in quick succession in the first hour I was watching.

One of many vessels that passed by Race Rocks today.

It’s amazing how much traffic there is in the Juan de Fuca Strait. It’s possible to watch and get details on the ships in real time here.

I started the day by washing the solar panels–a necessary task given the amount of bird droppings on them.  They’ve been outfitted with bird spikes, but on my last panel today, I found this:

Yes, a gull demonstrating how clever he (or she) is in defeating the mechanisms we put in place to stop them. Just step on the flat side, not the pointy end!

A closer look revealed something else.  This bird is banded!!!  For bird banders, there’s little more exciting than finding out what has happened to birds you banded. That happens when others observe or find the bands, determine the band number, and report that information to reportband.gov  . Of course, I didn’t have my camera with me, and the bird also wasn’t going to stick around. In fact, it flew. The good news is that most of the gulls on the island are at least somewhat predictable as they are on territories right now. I saw him fly around the lighthouse but not come out the other side.  It was possible he was very close by.  When I finished the panel cleaning, I grabbed my camera from the generator room, and went off in search of a gull among 700. It didn’t take me too long to find him, but not in a very convenient spot.

Each bird band has a unique set of nine numbers.  You need them all to positively identify the bird.  This means you have to get a decent photo of all sides of the band, and that can take a bit of patience.  Fortunately, I have that! My presence riled the gulls enough that they were all yelling at me and the banded gull came in to help chase me off. That was good enough to get me a partial set of numbers.  Now I had to get him from the other side. I moved closer to the house and waited. After about 4 times of him coming to the ground and flying off, I finally had all the numbers!

If you ever find or photograph a bird band, you should report it to reportband.gov. There are a series of questions to answer, but in the end, you will learn about the banding of the bird and receive a certificate of appreciation.

Ecological Notes:

Mammals

1 male Elephant Seal – departed today after molt. After he spent the night at the dock last night, I suspected this might happen.  He was in the water most of the day, and when I looked for him around suppertime, he was nowhere to be seen.

Steller’s Sea Lions – Good numbers now on Great Race Island

California Sea Lions – Numbers increasing dramatically on Great Race and surrounding islands

 

Harbour Seals – Many throughout the area

Birds

7 Black Oystercatcher, including young bird near the dock

18 Black Turnstone

5 Least Sandpiper

1 Western Sandpiper

Western Sandpiper in the lead, followed by Least Sandpiper

11 Common Murre

136 Pigeon Guillemot counted by clicker at around 8 am. There could be more, but no fewer.  Many catching gunnels or blennies (see last bird on right).

3 Heermann’s Gull

400 California Gull, mostly feeding on krill today

700 Glaucous-winged Gull, including 1 banded

Tussles like this are going on all the time

6 Pelagic Cormorant

1 Bald Eagle on Turbine Island at dawn

22 Purple Martin – biggest bird surprise of the day! Flock circled the lighthouse at 8:35 pm and continued south. Only flyovers I have seen this week.

1 Song Sparrow, rummaging in the compost

 

Facility Work: Cleaned solar panels. Not one window had gull droppings today, thanks to the calm winds.

Vessel Traffic: Many vessels in the shipping lanes today. Smaller than usual number of eco-tourism vessels, likely due to Biggs Orcas in other areas around the region. Several private fishing vessels came by the dock because of the sea lions.

Infractions: Private vessel coming through the reserve at too high a speed. Warned them to slow down, which they did.

Weather Events:  First day of noticeable smoke from fires on the mainland. Reduced visibility. Low winds from the south and east.

Wildfire smoke was present all day.

Vessel – Abigail fishing in Race Rocks RCA

First observed at location *F with binoculars at 0857, they saw me on the deck and reeled in lines. I returned to deck and took photo 1 as they jetted away. (high speed within the reserve)

They returned to the RCA at 0922, photos 2,3,4 taken for overview of location and ID.

After photo 5 and 6, I attempted to contact them on VHF 16 and 68 (was just going to politely suggest they check the regulations for Rockfish Conservation information). They were even closer to the North Rock by this time.

They looked up, reeled in lines fast, and again jetted off.

CODAR SeaSonde continuous surface current mapping and wave monitoring HF radar system.

This is taken from this page: http://vocab.nerc.ac.uk/collection/L22/current/TOOL1366/

http://vocab.nerc.ac.uk/collection/L22/current/TOOL1366/
SeaVoX Device Catalogue
Preferred Label CODAR SeaSonde continuous surface current mapping and wave monitoring HF radar system
Definition A high-frequency radar system designed for fixed deployment on the shore or on offshore structures. It measures continuous sea-surface current velocities and wavefield conditions such as significant wave height, dominant on-shore direction and dominant wave period. The CODAR SeaSonde transmits radio waves, receives Doppler-shifted reflected signals and processes the resulting data into radial ocean current velocities. The data from two or more radial stations can be combined into total velocities, i.e. ocean currents resolved into their N-S and E-W components. Total velocities are available only in regions of overlap with other stations. For wave measurements, the SeaSonde works on the principal of Bragg scattering; radial stations detect radar backscatter from ocean waves with wavelengths one-half the radar wavelength. The radar system is available in three configurations: Standard, Hi-Res and Long-Range. The SeaSonde’s spatial range varies from 15 – 220 km (dependent on the configuration), and offers 360 degrees coverage. The angular resolution is a 1-5 degree grid and is user selectable. Significant wave height accuracy is 7-15 percent, dominant on-shore direction accuracy is 5-12 degrees, wave period accuracy is 0.6 s, current accuracy is typically <7 percent of the total current velocity.

Kayaker in trouble

Posted on by

Rescue day:
Early this morning I was very surprised to find a person yelling at my door for help.  The man was very upset and his broken English difficult to understand, but I eventually figured out that his friend was in trouble.

The pair were fishing in the protected marine reserve when the push peddles on the friends kayak broke. I spotted the kayaker on the south west side of the Main Island, and it was quickly being pushed out on a big ebb tide to the west. The kayaker was trying to paddle against the five knot tide. Witnessing very little progress, I learned the fishermen were not carrying a VHF radio and carried unworkable mobile phones (which often don’t work on the south side without a US plan or roaming).  I immediately took action to launch the Race Rocks boat but the low tide and risky boat ramp conditions would not allow the boat to launch. There was simply not enough water to float the Race Rocks boat to help the kayaker.

Immediately, I contacted the Coast Guard (my cell phone *16) and they tasked out a RIB and lifeboat from Victoria. Myself and the Coast Guard were in constant communication about the troubled kayaker. While in communication, the kayaker managed to find a back eddy and travel to land on the south beach of the Main Island. After a discussion with the kayakers, they decided they were too exhausted from paddling to safely travel back to the mainland, even if they waited for the a slower tide. I confirmed their request with the Coast Guard who continued with the rescue.

One of my responsibilities as eco-guardian is to inform the public about the eco-reserve as a marine protected area. This means there is no fishing, crabbing or prawning permitted. Clearly, the kayaks were both outfitted with all the gear to crab, fish and prawn including a big capture net. I informed the kayakers the Coast Guard may have some questions as to why they were illegally fishing in the protected marine park. To record the incident, I quickly went to the main house to grab my camera.  By the time I returned to the kayakers, the man with the working kayak was paddling frantically back to the mainland shore. Soon he was caught in the ebb tide and heading out to sea. The fear of getting in trouble with the Coast Guard was enough for him to abandon his fishing buddy.

The Coast Guard arrived within 17 minutes from the first call. They picked up the broken kayak and the exhausted kayaker. By now, the second kayaker was on the north west side of the main island in the ebb and quickly heading out to sea. The Coast Guard pulled him and the boat after a 45-minute paddle against the very strong ebb.

As a seasoned marine captain, I have several lessons to share about this incident.  First, don’t head out into the Juan de Fuca straight without being prepared for an emergency. Always carry a VHS radio and/or reliable mobile phone plan.  Second, don’t crab, fish or prawn in a protected marine park. Always check fishing regulations and tide tables. Third, don’t abandon a fishing buddy, no matter the circumstances.  The buddy system saves lives.

Thank you to the Coast Guard for their hard work and commitment.  I am happy to report that both men were returned home safely.

Best wishes,

Captain Rod King
