A few boats cruising by today, mostly pleasure crafts and a couple tour boats and even a couple sailboats and kayaks on this beautiful day
Greg will also be dropping by this afternoon to bring some water and food
Ecological
the tagged elephant seal that the previous ecoguardians named Eric turns out to be an Erica, she is female
It is unusual for a juvenile elephant to be sticking around an area for this length of time, typically they would be moving along the coast now
There are so many sea lions right now and it seems she does not mind the smell or the noise but it isn’t unusual for elephant seals and sea lions to be hanging out together
More boat traffic on the nice days and there was also a dive boat with a couple divers on the east side of the island, it looked recreational
Ecological
The little steller is still around and adorable
seems like even more sea lions today but that might be because they are so concentrated around the helipad and the jetty but at least they are away from the burial cairns and the generator room/lighthouse
Maintenance
Fuel and water have been delivered recently and hopefully in the next week we get more decluttering done around the island and start bucking up some more firewood so we have enough to last the year since driftwood does take months to dry out enough to be usable
The past few days we have seen more pleasure crafts than tour boats and these pleasure crafts get way too close and I can never find them on the radio because it is very hard to know which channel they are on
A group students stayed Saturday night to film around the island looking at ecological impacts which around here are mostly due to sea lions trampling all the green and turning it into mud
Ecological
The little steller is still around, haven’t noticed any new injuries on any of the sea lions
the sea lion that was by the jetty before that seemed lethargic and didn’t really respond to people left for 2 maybe 3 days and is now back in the same spot and it is much more energetic and responsive than before
the number of sea lions seems to have gone up from the last census by about 100, will post more numbers below
I have been consistently seeing about two humpback whales per day
Maintenance
The fence now only needs typically one minor repair per day, the sea lions are getting used to staying away from it
I still need to stay on top of clearing them away from certain areas, they seem to not crowd the entrance to the generator room anymore or the burial cairns as much, but they have taken a strong liking to the grass around the lighthouse
Since I got back on Tuesday there have been approximately 15 boats per day, the number varies a bit each day
On tuesday and thursday we had visitors from the eagle wing crew come for a tour on Race Rocks. It was so nice for them to be able to come check out what Race Rocks looks like from the land after seeing it from the water so many times
Greg and Guy are coming by today so we can do a more in depth orientation on the projects and maintenance going on around the island
Ecological
After my walk around I noticed a couple interesting things, first there was a young steller, not a baby but he was still nursing.
Then an elephant seal, which was so nice to see and it had a green tag on it. Unfortunately by the time I got my camera it was already gone.
There have also been humpbacks nearby lately, the past two days there have been 4. Yesterday when the eagle wing crew was here was saw a fishing boat getting way to close to the whales, the whales were clearly upset and one jumped right out of the water because of it. Luckily we saw one of the whale watching boats from BC tours and got a hold of them and they let us know they had a word with the fishing boat about keeping its distance from the animals.
Maintenance
The fence still needs to be repaired twice a day but the sea lions are starting to stay away from the entrance to the generator room with regular clearing which will also start happening around the burial cairns between the student house and the helicopter pad. The sea lions have started shifting the stones around a lot and we want to preserve this important historic area.
I am back on Race Rocks, this is my third year but I’m only staying for 3 months this time. I am very happy to be back and look forward to a beautiful and productive autumn.
Today I plan to take a good look around the island and see if any of the sea lions have any injuries and just do a good once over.
I’ve spent the last 5 months with the whale watching community and here are some things I have learned. The whale watchers care about these animals as much as I do and our goal is education. We enjoy sharing this beautiful ocean and our knowledge of these animals with other people. The observations I’ve made during this summer are that many commercial boats do keep a respectful distance. The whale watching boats actually help me out as an ecoguardian. There are plenty of areas in the reserve that are out of my sight and if they see an injured animal they notify me and tell me where it is so I can monitor it and let marine mammal rescue know. If someone is doing activity within the reserve that shouldn’t be like fishing or snorkeling in a dangerous area they let that boat know that they can’t do that. I have a very difficult time trying to get a hold of pleasure crafts because they are always on different radio channels so this really helps me when others look out for the safety of the reserve and others within the reserve.
This island is a special place for many people and so much goes into protecting this ecological reserve and I just wanted to acknowledge a group of people who have helped in many ways to protect Race Rocks.
We received a response from the scientists who had tagged the elephant seal mentioned and pictured in this previous post. They were able to share some interesting information about GE103, whom we nicknamed Eric. GE103 was part of a mother and pup interaction study, as well as the subject of a blubber biopsy study.
“Eric”, GE103
Juliette Linossier, a researcher working under a Fyssen grant at UC Santa Cruz/Año Nuevo Reserve, was able to tell us more about the early life of this animal and others. She told us that shortly after the birth of another elephant seal (GE338), there was a huge storm at Año Nuevo and GE338 was separated from it’s mother. The pup was stuck on the beach, and his mother in an protected elevated area. They called to each other for a long while, but were never able to return to each other. GE338 did survive but was nursed by another female in the colony.
The now ’empty nest’ mother of GE338 became attached to GE103! She nursed him, and stayed close to him and his mother, G9474. Thus, GE103 (or as we call him, Eric) was able to take advantage of more than one milk source as a pup; the two mothers even fought over him from time to time.
According to her bio, Juliette wants to investigate the link between allonursing and maternal cognitive abilities using new approaches. Using time-lapse photography, chemical profiles and other techniques she plans to look at variables such as maternal age, pup similarity, genetic connection, spacial proximity and more to further understand what drives allonursing in these interesting creatures. Thanks for sharing, Juliette!
GE103’s blubber biopsies were taken for the purpose of furthering the understanding of pollutants bioaccumulating in marine mammals. Read more about this subject here.
Many thanks to Patrick Robinson, director of Año Nuevo Reserve and lecturer at UC Santa Cruz, for helping us learn more about this work.
We left Race Rocks last Monday (October 30th), and hours before leaving we were surprised by the landing of a Bell 412EPI Coast Guard helicopter. They came to Race Rocks in order to replace the solar battery bank beside the foghorn (near the base of the lighthouse). We were able to get great video of them landing as well as taking off!
Unfortunately, as one can see at the left of the video the landing scared many sea lions off of the rock in a rush. Without knowing that they were coming we had no chance to gently move any vulnerable animals away from the helicopter pad. We were able to speak with someone at the college about this, and the Coast Guard will hopefully be able to better work with Race Rocks in the future to ensure the safety and comfort of the animals.
The pilot was kind enough to take a moment to show us around and allow us to take some pictures. He explained that a smaller helicopter could have been landed near the house, but the 412EPI’s cargo capacity (over 6000lbs) was needed to transport the batteries. The helicopter is powered by a Pratt & Whitney PT6T-9 turboshaft engine that makes over 2000hp (about 1500kW), and it’s made in Canada!

Fresh batteries getting installed.
That’s not your regular engine!
We enjoyed our time at Race Rocks (a big thanks to everyone who supported us during our term), and hope to return and continue this work protecting and observing the fragile ecosystems and the animals within. Until next time!
Corey, Guy, and a student with their visiting grandparents visited yesterday, and delivered water- the desalinator is on the horizon!
We are ending our term on Race Rocks tomorrow, so Greg and Guy will come for a debrief before the next eco-guardian takes over.
Yesterday we saw a pleasure craft enter the reserve and drop snorkelers into the water less than 100 m from our jetty, within 5 m of shore and the hauled out sea lions. The animals were distressed and swam around the snorkelers barking. The current was flooding very quickly (5 knots), which creates dangerous water currents, eddies, and upwellings. We as well as Corey in Second Nature motioned for the boat to move away, but they simply gathered the snorkelers and moved around the corner where they presumably thought we would not see them. An eco-tourism vessel in the reserve also noticed them and contacted us to let us know, out of concern for their safety given the animals present and the currents at the time.
In the past scuba divers and vessels have found themselves capsized or pulled away from their dive site and rescued by helicopter, and in 2015 a diver went missing and was found deceased days after they disappeared by a fisherman after rescue crews were not able to find them. We were especially concerned for this group’s safety due to lack of float marking their position and the frequent boating traffic through the reserve. In the past, seal pups have been decapitated by vessels passing through too quickly and unable to see them. If these snorkelers had been pulled away by the currents, there would have been a high chance of being struck by a vessel unable to see them in the rough water.
Snorkelers entering the water next in Race Passage.

Ecological:
The sea lions population continues to grow! We are having to repair the fences sometimes twice per day. It seems like a more powerful electric fence energizer could be a good idea.
We spotted a little Greylag goose among the Canadian geese yesterday.
The sea lion that we spotted on Sept. 12th with an apparent propeller wound to his head is still here. He stays near the jetty and seems to have some behavioural anomalies, presumably due to the head injury. He is not afraid of us like the others, and does not move away into the water with the others when we clear the jetty. We haven’t had any problems but are weary that his behaviour could be unpredictable. Marty (the vet that came to aid in rescuing the entangled sea lion) mentioned that sometimes when this happens a shard of their skull can splinter and cause a brain infection. We hope this little guy is on the mend.
There have been many Canadian Geese passing through this week; A few days ago we counted over 20. The geese are not native to the island, but according to Gary Fletcher they arrived somewhere in the 80’s as the population of geese on Vancouver Island were introduced/grew. Addling the eggs began somewhere in the late 90’s. Unfortunately, this year two nests survived and hatched goslings, meaning that 20 geese left the island after 8 nested here in the spring.
We removed 6 large garbage bags full of invasive “Canada” thistles over the past few days. Considered a “noxious weed” under the BC Weed control act, these perennial (grow back every year) weeds can reproduce through seed and root regeneration. Thought to have been introduced to North America via contaminated crop seed in the 1700’s, this plant is actually native to southeast Europe and Asia. Presumably they were introduced to Race Rocks by a visitor on clothing or equipment, or perhaps by an animal.
A big patch of thistles
Seeds
Much better!
They can be a bit laborious to remove, due to their tap root and ability to regenerate through “cloning” (growing back if you leave the root in the ground). Incredibly, the seeds can remain viable for 3-6 years when buried at typical depth, and some up to 21 years (yikes!). Each plant produces an average of 1500 seeds, but can sometimes exceed 5000.
Because of this, we collected them into garbage bags to remove from the island instead of composting them where they would have the opportunity to reproduce. Unfortunately it appeared that these aggressively persistent weeds were whipper snipped in past seasons, allowing the seeds to disperse and roots to regenerate. Hopefully with some attentiveness, they can be eradicated from Race Rocks in the next few years. More information on other introduced plants available in this post from Garry Fletcher, 2006.
Weather:
Sky partly cloudy, some sunshine
Visibility 15+ miles (some fog last night)
Wind 20-30 knots W
Water choppy, whitecaps
Visitors:
Today Laura (Pearson’s marine science teacher), and her class came for a bit for their first trip to Race Rocks! Two more classes will visit in the next couple of days.
Less frequent eco-tourism traffic now that the summer tourism has slowed down. They have been getting quite close to the sea lions though, often causing them to climb over each other to get further away from the vessels. Since it has been overcast, we’ve been seeing the use of flash photography much more, which seems to audibly cause quite a stir.
Ecological:
There have been some birds passing through that we don’t often see: western sandpiper, savannah sparrow, song sparrow, and juvenile sandpiper (or possibly sanderling- we have a hard time with bird ID!) Also, we think we spotted a yellow warbler a while back, but it was too speedy for us to snap a photo.
The sea lions have continued to haul out- notably, there are typically over 100 animals on the jetty alone.
A team comprised of the DFO and Vancouver Aquariums Marine Mammal Rescue (MMR) came out to Race Rocks on September 16th to help the entangled sea lions we’ve spotted over the last few weeks. Leaving from Pedder Bay at 0900, they arrived in two RHIBs at the reserve shortly after. After observing the struggling animals over the last while and communicating information with MMR, they were a welcomed sight.
MMR and DFO arrive at the edge of the reserve.
An eco tourism boat encounters the DFO support vessel in front of the jetty.
Right away we spotted three possibly entangled sea lions from the lighthouse (unfortunately none of these three being the animals we photographed previously). We then landed the team of vet techs and veterinarian Marty at the jetty to assess the situation. It was decided that one of the sea lions resting by the water between the guest house and the helicopter pad was our best rescue candidate.
The entangled sea lion.
Visual contact from the water!
Marty and a videographer from Vancouver Aquarium approached over the helicopter pad from the direction of ‘Camera 5’. They got into position and a shot was taken, but the tranquilizer dart bounced and the sea lion fled into the water.
Preparing the tranquilizer.
The sea lion was estimated to weigh 500kg, and the dose had to be measured accordingly.

From the lighthouse we were able to follow its movements and keep the team apprised by radio. There was uncertainty about whether or not it received a partial dose of the tranquilizer as it floated in strange positions/patterns. Moving around Race Rocks to the water beside the solar panel/generator building, it hauled out again and another shot at it was lined up from one of the boats. The angle wasn’t quite right, and it again fled into the ocean and couldn’t be spotted. It was around 1400, and everyone took a break to have some food.
After this, everyone considered calling it off as it was getting late and we couldn’t locate the animal. At the last moment, with both boats ready to head back to Pedder Bay, it was spotted from the lighthouse (resting on the rock mound on the NW point of Great Race Rock)! Tranquilizing was attempted from water, but the dart bounced again and landed in the water and was recovered. Here’s a short video of that:
After that, it ended up too far from the water to try another shot by boat, so in a final effort the one boat landed Marty and the team again while the other stayed on the water to support. With no cover available between him and the animal, Marty had no choice but to crawl about one hundred feet in order to take the shot.
The sea lion is sighted again on the point of NW Race Rock.

Gearing up for the land approach. Hopefully some good video was captured!
Marty moves over challenging terrain near our compost bins, staying low while managing to carry the large tranquilizer gun.

We were able to capture the following footage of the sea lion being darted, going into the water, and then after a tense 20 minutes during which a pod of transient orcas appeared in the reserve (who sometimes eat sea lions), it was found! The team proceeded to cradle the animal between their vessels and remove the plastic band. Then, they injected a reversal drug to reverse the tranquilizer before letting it go.
Everyone was relieved to have successfully helped an animal in need. We have suggested that future disentanglement efforts might have a better chance if extended to overnight stays in the guest house, and perhaps coordinated and executed in a more timely manner in relation to the animal sighting(s). This time we were unable to find the original animals that we had previously spotted, since it took quite a while to organize the rescue attempt. A big thank you to everyone who came to help this sea lion and teach us about their work!

Thanks to the rescue team, one more sea lion has a better chance of survival! (vet Marty holding the dart gun and dart used to tranquilize the sea lion)
Sky partially overcast, some light showers throughout the week
Visibility 15 miles this morning, consistent throughout the day, some heavy fog a few days ago
Wind 10-15 knots W
Water ranging from calm to choppy with waves up to 1.5m over the last few days
Boats/Visitors:
There’s been a lot going on over the past few days! Our apologies for the lapse in updates.
On Monday, after a few weeks of planning, the Marine Mammal Rescue team from the Vancouver Aquarium came out to RR with support from DFO, to attempt disentanglement of the troubled sea lions we’ve been spotting. Stay tuned for an in-depth post detailing the days events with many photos and videos!
We have been having minor trouble with the water supply/storage for our house here, but with a little investigation and some extra water deliveries it seems to be changing for the better!
With water deliveries, there have been a handful of guests, notably including a guest speaker visiting the college to address students. It’s always nice to see some friendly faces!
Ecological:
The sea lions continue to haul out in larger numbers, but it seems to be tapering off. Our electric fence lines are holding better as they learn (through trial and error) not to push through them.
Young seagulls are naive to the danger sea lions pose – we have observed juvenile birds being trampled to death by a sea lion simply moving quickly to a different area of the rock. The birds who learn quickly live to fish another day…
Over our time on Race Rocks we have been finding plastic/general garbage across the island compressed into a similar size and shape. After observing a seagull regurgitate a condiment packet (ex: rectangular, fast food style ketchup package), we believe this plastic to be consumed by seagulls on land or at sea, and then carried back to Race Rocks when the birds come to feed their young or rest. Regurgitating the foreign waste, perhaps to feed their offspring or out of discomfort, they deposit this human trash here.
Here are some picture showing the plastic/garbage described above:
We find compressed balls of trash like this, the size of what a seagull is capable of regurgitating
A common find: cheese stick wrappers
Another cheese stick wrapper
On closer inspection, this appears to be a ball of dental floss tangled up with small vertebrae.
A collection of trash we collected from around Race Rocks.
We assume this came to the island in or with an animal, no starbucks out here!
On the note of seagull diet, here are some picture of sea life remains found around RR which would seem to be left overs (and examples of what they should be eating) – talk about sea food from the source!
