Race Rocks Ecological Reserve #97 Wardens Report December 2023

Wardens Report by Garry Fletcher.. December 13, 2023

Past Wardens reports may be accessed at https://racerocks.ca/category/er-warden-report/

I got a ride out on the Second Nature vessel of Lester Pearson College. Greg and Cedrick were taking out two technicians to deal with problems with the Solar panels and the diesel engine. 

A herd of California Sea lions who have become accustomed to boats landing at the docks greeted us at the docks.

On the North side of the island there were mainly California sealions. 

The Northern sealions predominated on the south side of the island Their distinctive growl and larger size sets them apart from the California Sea lions 

For the several hours that the technicians were busy in the engine room I could  check out the whole island. Additional solar panels have been added to the array shown in the video below taken from the roof of the energy building/engine room. In the winter the diesel engine has to run for a few hours to help charge the batteries. 

 

From the helicopter pad I observed a very nervous mixed herd of California and Northern sealions that were occupying the area on the West side of the island, preventing me from going in that direction to check out the tidepools. 

Race Rocks must be one of the few outdoor locations in British Columbia where flowers bloom year round because of the surrounding waters never dropping below 8 degrees C which moderates the temperature.

There were many Black turnstones around the island. They are found here year round although they are not known to nest here.

 

 

There has been a high number of gull mortalities this past year. This one is missing the breasts indicating it was a meal for the Bald Eagles. They now patrol the area regularly and this has probably contributed to the low number of overwintering gulls.

The absence in overwintering seagulls at this time of of year  was very obvious. Ined some years they have number in the thousands. The south-west corner which usually is heavily populated only had a dozen of probably brants cormorants, and a small flock of less than 100 gulls was on the north-east corner of the island

While I was there , Greg and Cedrick from Pearson College helped in cleaning gutters, definitely a two-man job for safety reasons, and hauling up some of the logs in the harbour by the slipway for cutting up for firewood. 

SOME WORK YET TO BE DONE: 

Managing a former light station and an Ecological Reserve can be a large job.  Pearson College does an admirable job in fundraising to keep the place going. It is after all the only Ecological Reserve in the province which has human dwellings and a full time Ecoguardian paid for by Pearson College. Since 1997 Pearson College has taken on the role of management of these facilities which require constant upkeep in a very demanding physical and biological environment. I will point out several items below that are needing attention. 

 

This is the last of the old storage tanks used by the coastguard. They await removal. It is just a matter of time until the salty environment encouraging the rust could cause further problems. 

 

Below are some suggestions I would like to make about things that are not urgent but to which attention may be paid in the future. 

The rock wall which was eroded by the hurricane in 2006 Is still in a partly fallen state, contributing to bare soil and erosion.  It wouldn’t take much effort to repair this to improve the stability of the area. ( maybe a student project week item?)

 

At one time the area under these artifacts was covered  with bricks from the original engine room. The bricks are still there but they are now overgrown with grass. Removal of the overburden would improve the appearance of the area.

50th Anniversary of Ecological Reserves in British Columbia

Often when we visit special ecological areas our observations are restricted to a limited view. In this video, we visited six diverse Ecological Reserves  with the goal of revealing some of their special features from  a distant viewpoint as well as a close up one. Under a special permit from BC Parks, Jamie Frith used his drone and a macrophotographic camera to enable us to present a unique perspective on the reserves.

This video was made for the Friends of Ecological Reserves with the support of BC Parks. We started the project in March 2021 and originally were only allowed by  BC Parks to film in  6 Ecological Reserves in the southern part of Vancouver Island due to restrictions of COVID 19. Plans to include ERs from the interior of the province also were not possible   As those restrictions were eased mid summer, we were able to extend our range and travel North to include the Nimpkish River ER,  in order to include a  representative area of mature Douglas Fir forest.

Ecological Reserves which we were able to include were: 

  • Nimpkish RIver  ER#118   start time- 1:20
  • San Juan RIdge  ER #83   start time- 5:58
  • Oak Bay Islands  ER #94    start time-11:02
  • Mount Tzuhalem  ER#112    start time- 16:38
  • San Juan River  ER#141   start time-  25:01
  • Race Rocks  ER#97    start time- 25.03

 

One of the goals of the Ecological reserves act is to provide protected places for research and education. Some reserves, especially those with seabird colonies  are closed to the public and only accessible  with a permit from BC Parks. Since it is illegal to fly a drone over any provincial (or federal) protected area without a permit, the use of the drone was possible only with permission and precautions for no disruption to animals.  As mentioned in several of the interviews, because of the sensitive ecological nature of the areas, the public is not encouraged to visit Ecological reserves.

THE 50th ANNIVERSARY: 
On April 2, 1971, the Government of British Columbia became the first jurisdiction in Canada to pass legislation to protect Ecological Reserves, places set aside primarily for ecological research and education, not recreation. The Ecological Reserve Act led to an Order in Council that established the first 29 ecological reserves on May 4, 1971. Fifty years later, British Columbia has 148 ecological reserves across the entire province. This video features just a few of the ones on Vancouver Island. In 2021, the BC government proclaimed April 2nd as Ecological Reserves Day in commemoration of the 50th anniversary of the passing of the Ecological Reserve Act.

Protecting rare species and ecosystems is just one of the reasons to have an ER established. Equally important was protecting representative examples of natural ecosystems. See the wording in the Purpose section of the ER Act:

Many Visitors at Race Rocks

Ecological Notes:

Race Rocks is a wealth of biodiversity, and an amazing place to get to spend any amount of time. Despite the huge amount of wildlife that spend time on Race Rocks over the winter, it can feel a little quiet. Not last week!

We were super lucky getting some of the Pearson College students out despite COVID lockdowns on Campus, this is always one of the highlights of our time at Race Rocks! The kids always have the best questions and remind me why I pursued the life I live now. Any opportunity to share the joy and smells of Race Rocks.

After the final group of students left, we got a surprise visit from DFO via their helicopter coming by for a socially-distanced visit. We had a helicopter buzzing us throughout the week, and it wasn’t until it landed at the end of the week we realized that was most likely the crew checking out the island, seals, and heli-pad. The elephant seals clearly weren’t fans of the helicopter. Interesting-ly the idling helicopter covers the same sound frequencies the Beachmaster uses to drum his dominance. Our Beachmaster tried drumming at the intruder, but he couldn’t overpower the sound and decided that abandoning his harem and a trip into the ocean was preferable to hanging out with a helicopter.

The next day we woke up to a new female Elephant Seal! We suspect this seal was Tyra from last year, going off her scar patterns and BEAUTIFUL eyes. At this point in the season we have expectations for these seals: they come ashore, hang out for 5 days, give birth, nurse for 21 days, mate and leave. Tyra was a reminder that we don’t really know that much about these mysterious animals. She came ashore, mated, and left. She looked great, very plump. I am really quite surprised. Maybe not all pregnancies come to term, and in that light her behaviour actually makes a lot of sense. She needs to come ashore when a Beachmaster is ready to mate, and if she doesn’t have a pup to birth then there really isn’t a reason to stick around and wait until it’s time to moult.

Tyra returning to Race Rocks to visit the Beachmaster. All hail the Beachmaster!

And we had a new pup born! I told you lots happened. Rhi-Rhi has been ashore since January 25th and slipped out a new pup this morning. The new pup is super chirpy, and very mobile; it had a very ‘rolled up’ vibe directly after being born, with curled fingernails and it’s giant flippers wrapped around itself. We expect her to nurse until the 22nd of February, but clearly I need to stop trying to predict what these animals are going to do.

Rhi-Rhi inspecting her newborn pup.

Facility Work:

Race Rocks has a Boston Whaler from it’s Coast Guard era that can be used in case of an emergency. During a very low tide we figured this was the ideal time to re-spool the twisted up cable used to launch the boat. While it’s easy to think that emergencies never happen, it’s great to know that in that hypothetical situation the boat will be able to be launched on any tide without any problems. Big thanks to the previous Eco-Guardians who did some great boat maintenance!

DND events:

Lots of blasting over the last week, some of the Pearson College students were definitely surprised.

Elephant Seals seem happiest when all smushed up against each other.

Feature Event:

We had someone report a wayward Elephant Seals wandering around Sturdees Beach & the Gorge vale Golf Club. This fits very well with the theme of ‘we don’t really know much about Elephant Seals’ and thought it would be worth mentioning. As the Northern Elephant Seal population continues to recover, hopefully we’ll all get to experience more Elephant Seals in British Colombia, and sometimes that might be a returning pup who hasn’t really figured out the timing of things yet. They’re really remarkable animals, who spend a very small proportion of their time (<10%) above the water Over the last 2 years there have been wayward pups reported crawling around in areas where they were not wanted, these little seals are just looking for some place safe to moult and head back into the ocean. This is one of the parts that makes Race Rocks such an important place for these animals: a place on land where the seals can hang out and sleep without being disturbed: their time on land relies on them fasting for weeks on end losing up to 40% of their body weight during these stints. Every time they get woken up or stressed that is another drain on their limited energy available, leading to the first couple of years where mortality can be up to 75%.

The silver colouration shows this wayward pup has already moulted, so probably from last years birthing season. While we would expect pups to return to Race Rocks to moult, we don’t really know how they return to the same areas, and they may just try out new areas at different times; or just get lost.

Weather Events:

It was a lovely week of weather, punctuated with a nice little blast of wind of 40 knots+ Sunday and Monday.

The first pup Mikey is already starting to moult his soft baby fuzz into a silvery sleek diving suit of fur at 41 days old.

New Elephant Seal + Pupdate

Rhi=Rhi came back and is ready to birth!

Ecological Notes:

We have a new female Elephant Seal on Race Rocks! While she looks suspiciously like one of the returning mothers, without a tag it is hard to tell. She was thoroughly investigated by our local Beachmaster, and sassed Mikey for getting too close. Mikey seems to have learned his lesson to stay out the Beachmasters way, after a few small bites Mikey is now quite mobile and has learned the paths on the island to avoid further conflict.

Lil Blasty in one of the few moments not blasting squawks.

As for the other Elephant Seal Pup: named Nereo by it’s mothers namesake, but I have been referring to it as ‘Lil Blasty’ due to his extreme volume while ‘chirping’. The current theory is that Elephant Seal moms and pups learn each others vocalizations to identify each other, and regardless of the background noise present, they seem to always vocalize at the same volume.

Jocelyn’s vocalizations come in around 50-70db, where Lil Blasty is clocking in at 100-110db with his vocalizations. For reference: WCB recommends not being exposed to over 85db for prolonged times due to hearing damage. It definitely hurts to be outside when he’s shrieking.

The Beachmaster being grumpy that no one wants to mate with him.

Facility Work:

We bucked up the logs that were snagged over the last week, and got them off the boat/seal ramp. Heavy algae growth over the last 2 weeks so we’re started pressure washing the algae to keep things from getting too slipper.

DND events:

Canada’s Navy has started doing tester laps outside of Esquimalt.

Feature Event:

Mikey has learned to avoid the Beachmaster when he’s on the prowl, and decided to explore off the beaten path to avoid any conflict. We suspected he would fall off the ‘mountain’ climbed today, but displayed some remarkable manoeuvrability for a chubby little seal.

Mikey mountain-climbing.

A hallmark of the maturing pup is the wear-pattern on their chins. The chin is a key instrument for Elephant Seal locomotion: where they re-arrange their belly by lifting it up with their chin. The chin can also work to level the seals bulk up onto rocks, steps, and rough terrain.

Mikey starting to show his all-important chin patch.

Weather Events:

January means the start of some epic sunsets.

The last couple of days the temperature has dropped down to 4°C with light N winds around 10-15knots. This is log weather.

Revisiting Intertidal Transect sites at Race Rocks

Watden’s Report, September 3, 2021

I was fortunate to be able to get out to Race Rocks on one of the last morning low tides of the season. I wanted to revisit intertidal locations around the island in order to take photos of belt transects in locations I had recorded with baseline studies back in May of 1995. Photographic transects are valuable records in the event of changes that may happen along coastlines, usually caused by humans and/or by extreme weather events . 

 

Images taken in 1995 can be seen in this index on transects: https://racerocks.ca/ecology/ecological-monitoring/

The belt transect files with images will be linked here when they have been processed :

Peg 6  Peg5: Peg 5a  Peg 5b Peg 14a,  Peg 14b Peg 115. 

I was fortunate to have the assistance of Cedric Torres, the ecoguardian in doing the work on the transects.

 

At this time of year the island is populated by many young  glaucous-winged gulls, some fully fledged and other son various states of maturity. There were also a number of mortalities around the island which is typical for this time of year in a breeding colony.  In the following videos a number of behaviours of the chicks are shown .

Harbour seals with pups are hauled out on the southern most reef, note the current was still  ebbing in this video.

The California and Stellers sea lions have started coming back in large numbers. typically the Californias outnumber the Stelllers at this time of year.

Beneath the tower, the Californians( barking)  are predominant: but there is alos a mix of the growling Stellers.

 

On the East side cove a large group of Californian Sea lions were hauled out. The ones here were very skittish, any movement near the east end of the  house would startle them

.

Other observations : two orcas in Race Passage ( surprizingly with no whale watching boats nearby.  The nice weather on Sept 3 brought out many whale watching boats and as usual they approach closer to the north side in front of the docks than necessary and well within the distance for viewing marine mammal colonies. The sea lions on that side are more habituated to the presence of humans and these boats than on other parts of the island, but many still go into an alert stage when the boats pass by.

Only a few pelagic cormorants were seen on the south west tip of the island.

The Calendula escapes from gardens of lightkeepers over 50 years ago still exist along the pathways, although the dry summer has been challenging. I was able to make a new species observation of these green blow flies on the flowers.

 

This summer with the heat dome experience on Vancouver Island there have been reports of damage to intertidal life. I took these images of high intertidal level barnacles in the arintertidal between peg 14 and 15. which show very little damage from this event,

We checked out Anita’s pool #6 . The intertidal life in the area has been unchanged for decades.

On the west side of the cliff near peg 5 , we took these images on the vertical rock face as records of barnacle distribution:

And near peg 15 we noted these finger limpets in a shaded rock at an extreme high intertidal elevation.

And a follow-up photo of The ill-fated tidepool #13 which was readjusted in the hurricane of 2006

 

 

 

 

 

Elephant Seal Bubbles

This was my first full day at Race Rocks and it started with a fog check at 5 am. One of the volunteers from nearby Rocky Point Bird Observatory was interested in doing a simultaneous comparative seawatch from Beechey Head and Race Rocks to determine if the birds leaving Beechey also passed Race, and if so, how long it took.  The weather was clear, and the challenge was on!  But there was a glitch.  Nothing was passing Race Rocks, as there was a sea full of krill and to the west. I climbed the tower to do my watch, and found about 600 California Gulls already in the reserve picking at the krill near the water’s surface. The few alcids that made it here during the one hour watch (from 6:30-7:30) quickly set down rather than flying through. Most (if not all) of the birds Daniel counted at Beechey Head were not counted here.  We’ll try again.

Regurgitated krill

On a more entertaining note, the Elephant Seal went for a stroll today, all the way to the dock. I looked out the window at about 12:30, and there he wasn’t.  I ran out to see if he was really gone. Whew! Not yet!

He was working his way to the dock.

And eventually got to the water’s edge where he proceeded to stick his face in the water and blow bubbles. How exciting!! If you’d like to see some videos of this event, click here. (By the way, I am using a 600mm lens and keeping my distance!)

I was thrilled!  I thought it meant that he was on his way and could start eating again. Several wildlife watching vessels came by and were delighted to see him.  But apparently, this is a daily sojourn for him. Sure enough, as Greg Dickinson predicted, he returned to his resting spot after his trip to the beach!  Looks like he’s not done yet.

Elephant Seals From the Remote Control Camera

Elephant seal pups

Three mother Elephant seals and two of the pups, the newest pup is hiding beyond the top right mom.

This year, so far there has been a very successful set of births of Elephant seals at Race Rocks. This is the 13th year that Elephant seals have been breeding and having births in the ecological reserve.  Currently three females and four pups along with a large male can be seen from the remote-controlled  camera 1 from the top of the tower:

Humpback Whales Feeding off Race Rocks

There has been 2 humpbacks hanging around the Becher Bay – Race Passage for the last couple of weeks. They have always been a little bit distant from the Lighthouse, but on December 30th 2020 they came right up to the SW corner of the lighthouse and did some feeding right at the current line. There’s lots of turbulence, so it could be some bubblenetting or lungefeeding. Really cool to see them use the crazy currents around Race Rocks to get a meal in.

Elephant Seal Pup Growth – Day by day

The first Elephant Seal pup of the 2021 birthing season came on December 22 2020, and began it’s 23 days of nursing the day after (it took him awhile to figure out how to nurse). Elephant seal pups only have a couple of weeks to get big enough and healthy enough to survive alone after their moms wean them and abandon them on Race Rocks; which means their life is essentially just to feed, nap, and snuggle with their moms. It’s hard to show how impressive it is to see how fast they put on weight, with the pup doubling in size over the first few days. Here’s a video of the growth of ‘Cheermeister’ over his first 12 days of life.

The Problem with Ocean Fouling/succession-

When installing equipment underwater in a high current zone where the water is laden with nutrients from upwelling as it is at Race Rocks, it becomes obvious very soon that any new substrate placed underwater becomes an instant habitat for the settlement of many invertebrate and algal species. For this page I have brought together different examples from the work we did over the years at Race Rocks.  . It should be noted that the word “fouling”is a rather perjorative term, seen from the point of view of a natural process interfering with human wishes.  However,  it simply represents ecological succession, a perfectly natural event in a highly productive environment, and too bad that it inconvieniences us!

This video from 2001 shows what the condition of the growth of life was on a sensor bar that we installed in water at 8 meters depth just off the Jetty at Race Rocks: The sensors were for monitoring Oxygen, salinity, ph, and turbidity. Without constant attention by our divers getting accurate data from sensors like these over a long term would not be possible. This video was taken after three months in the water .

 

 

 

In September of 2011 we ended the experimental Tidal energy Project at Race Rocks.  This file has images of the turbine covered in fouling organisms when it was raised for the final time: 

 

 

 

Examination of the tidal energy installation after being installed for 6 months

 

 

 

The engineers concern for the kind of materials they were going to use in constructing the turbine were addressed by having the Pearson College Divers install a series of succession plates that could be monitored for growth over several months.

 

Video inspection done by Chris Blondeau on turbine inspection before removal, June, 2011 The growth of Invertebrtates is quite incredible. Since ther is little opportunity for predators like starfish to browse on this column, growth is unimpeded. This led us to decid that the i meter wide .. 15 metre high column should remain in place after the turbine was removed as such it has turned out to be such a unique  habitat.

 

Another example of succession is evident in the way that kelp attaches to a solid substrate and can end up in modifying the environment. In this case moving rocks from ocean to shore.
