Recent Changes and Updates on this website

Posted on by

A year ago , we lost the services of storage on a Telus service without any warning. As a result all files, photos and documents, which had URLs starting with racerocks.com were not accessible, but fortunately I had a backup, so now I have been  gradually getting caught up in transferring several hundred items to this wordpress site which now carries the racerocks.ca archives.

Some of the more significant files which have been updated are as follows:

  1. The Race Rocks Species list and Image Gallery- species photographed at Race Rocks
  2. Weather and Physical factors at Race Rocks– all the abiotic factors pages have been redone– example: tidal currents: and wind
  3. Media Coverage of Race Rocks stories
  4. Archive of Events at Race Rocks 
  5. .The History of the Development of the racerocks.com millenium  Project
  6. The Situation with MPA status for Race Rocks
  7. Archives of the Tidal Energy project
  8. The Contributions of Pam Birley of Leicestershire England
  9. Current and Archived Video
  10. Archival records 1859-1906
  11. A translate dropdown menu has been added to the top of most pages and it should always be embedded at the top of the log posts if one logs in from the URL racerocks.ca
  12. Two archival files from the 1980s and 1990s  have been added recently; The Salmon Enhancement Activity and CoastWatch program activity
  13. Transects for Environmental Monitoring at Race Rocks

 

Christmas Bird Counts 2017-present year

Posted on by

Records for 2017 to 2020–
THE ANNUAL CHRISTMAS BIRD COUNT AT RACE ROCKS
This data below may be highlighted, copied and pasted to an open EXCEL file. It will then be usable for statistical manipulations and graphing exercises.Some of the records reflect seabirds observed on the trip from Bentinck Island out while on the boat. Due to inclement weather ( that means a wind above 15 knots from the north East usually, ) In 2018 and 2019  observations were carried out from Great Race Rock Island only, and the surrounding area visible from there.
Linked below are the count returns by year. Included are some of the photographs taken of the members by those who were able to make it out for the counts, –Garry Fletcher

Christmas Bird Count at Race Rocks 2020

Posted on by

Today was the annual Christmas bird count. Martin Stewart provided the transportation on the boat Ecosphere for Matt and Courtney Cameron to go out to Race Rocks Ecological reserve from Pedder Bay with Garry Fletcher. 

Observations were done from the marine a out through Pedder bay and then we docked at Race Rocks to be met by Courtney the Ecoguardian.  We had only a brief window of time, probably an hour  there before the wind started to pick up from the North East, but that was adequate to get a good count of the birds on shore.

Pam Birley from England took these photos on camera 5 :

Striking in their abundance were the and Pelagic and Brandts Cormorants. On leaving we circled around the South side of the islands and out past West Rock where there were also large numbers of cormorants.  From West Race Rocks we went over to Emdyck Pass behind Bentinck Island and found another large gathering of Cormorants, and some alcids.  The other bird that seemed much more frequent than previous years were the Black Turnstones

On the island, after stepping carefully past a male elephant seal on the jetty, we were able to view the new pup and mother elephant seal with the large male up on the lawn by the house. 

The following three sets of data are from their e-bird posts,

The Problem with Ocean Fouling/succession-

Posted on by

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.

 

Measurement Exercise

Posted on by

Today we had a request from Meghan Byrne, a 6th grade science teacher in the San Francisco Unified School District. She was doing a lesson with her students on size and scale and she was interested in using the following picture from this blog of the elephant seal measuring device – and letting students determine its length.

 

 

 

So I thought that would be a good exercise to include here for school students. Ecoguardian Mara has provided the following photos of the boat ramp rail so you can now calculate the length of the small elephant seal. 

Be sure to calculate the length of the Elephant seal in both centimeters and in inches.  Then you can also convert it to Metres and Feet . 

Mara sent another picture of a larger male, the brackets on the rail can just be made out so calculate his size.

The Origins of an Ecological Reserve-Trev Anderson turns 100

Posted on by

Trevor Anderson at age 100

On October 22nd  we were invited to the 100th year  birthday party for Trevor Anderson, the light keeper at Race Rocks when it became an Ecological Reserve. Trev and Flo Anderson had arrived at Race Rocks with their family in 1966, and served at the station until they had built a boat and left to sail across the Pacific Ocean in 1982. They had been married for 70 years in 2014  and  Flo Anderson passed away in 1977.

  I first met the Andersons in 1976 and the students from Lester Pearson College in the Diving Marine Science and Biology programs started coming out to the Islands for field trips and SCUBA diving, with some even spending their project weeks studying and working at the islands. Students in the Diving and Sea Rescue Services at Pearson College developed a close relationship with these neighbours 5 km out at sea. After many of our dive sessions whenour students were invited into their home for tea and cookies, the students would talk excitedly about the incredible sea-life they were seeing at under water. In the late 1970s we started to visit Race Rocks more frequently and the Andersons invited students to stay on project weeks. 

Trev and Flo were the first to plant the seed of an idea urging us to see if we could get the government to do some formal recognition and protection of the Race Rocks Area.  What they could see at low tide alone was impressive enough, but if the underwater life also could be protected, that would be ideal.  In the years 1997 and 1998 we recorded the unique life underwater by logging dives from over 80 locations throughout the Race Rocks archipelago, and by February of 1979 a highly successful workshop took place, with officials invited from the Provincial Museum, the University of Victoria, and the Ministry of Parks who were all enthusiastic and supportive of our proposal.

Throughout that year we worked at the task of formalizing our proposal, presenting it to cabinet and lobbying to get action. Two students in diving and marine science, Johan Ashuvud from Sweden and Jens Jensen from Denmark were especially relentless in their pursuit of our goal. The proposal had to clear 11 agencies in the government bureaucracy and the cabinet before the Reserve could be proclaimed. These two students invited the Director of the Ecological reserves Branch Bristol Foster, and the Deputy Minister of Parks Tom Lee out to dive and then kept following it up with phone calls, even after hours! Their persistence finally paid off when after a year, the shortest time any reserve proposal has ever taken, the Minister of Parks was able to request Prince Charles on his visit to the college as international board president (April 1980) to make the formal announcement proclaiming Race Rocks the 97th Provincial Ecological Reserve.

The day we received the information that the reserve was proclaimed by the Ecological Reserves Branch of the Ministry of Lands Parks and Housing, The group of students who had worked so hard on the proposal went out to Race Rocks to give the news to Trev and Flo and present them with a very unofficial looking sign. 

 

The next week Trev and Flo asked the group of students who had worked so hard to establish the Ecological Reserve to come out to the island one afternoon where they presented the students with medals and “The Order of Race Rocks” as recognition and appreciation for their work in creating the Ecological reserve.

Sea Lion Rescued Near Victoria (Times Colonist , Sept 9, 2020)

A sea lion with a plastic packing band cinched around its neck was rescued near Race Rocks on Sunday, thanks to the combined efforts of rescue teams from Victoria and Vancouver.

The struggling sea lion was first spotted by Mara Radawetz, who lives in the decommissioned lightkeepers’ residence at Race Rocks, just off the southern tip of Vancouver Island. Radawetz, who monitors the Race Rocks Ecological Reserve with partner Kai Westby on behalf ­Metchosin’s Pearson College, saw the sea lion several times during the week in nearby Juan de Fuca Strait, and said the marine ­mammal was clearly in distress.

“He was scratching constantly at his wounds, which were cutting into his skin,” ­Radawetz said.

She contacted Fisheries and Oceans Canada and the Vancouver Aquarium’s Marine Mammal Rescue Centre, Canada’s only dedicated marine mammal rescue facility and one of the largest rescue facilities in the world, to help free the sea lion from the plastic packing band wrapped around its neck.

Two large Zodiac boats ­carrying the rescue team and several veterinarians arrived Sunday morning, and quickly found the sea lion, Westby said. After being given a tranquilizer ­injection by veterinarian Martin Haulena from the Marine Mammal Rescue Centre, the sea lion was brought onto the shores of Race Rocks and treated.

The plastic band was removed and tracking tags were attached to the animal’s front flippers. A blood sample was also taken, to assist with future studies. After being given a drug to reverse the effects of the tranquilizer, the sea lion was back swimming within minutes, Westby said. “It was great to see them help out an animal that was in such great pain.”

Suffering caused by man-made material such as plastic is an increasingly common problem among sea lions, Westby said. As permanent residents on Race Rocks, he and Radawetz see their share of injuries to sea lions.

“It can be pretty sad to see. They live for 20 years or 30 years, and as the animal grows, the band cuts through its skin. It becomes a really painful-looking wound.”

Diving with Sea lions –and foolish diver behaviour

Posted on by

I am posting these videos from Youtube here with a precautionary warning; The behaviours demonstrated by some the divers could be very dangerous. Trying to touch sealions and putting a hand in their mouth and even staying in the water when they get agitated is very unwise. When a sealion starts snapping his teeth at an intruder it is best to move on.  A sealion bite can be very toxic, and they have been known to ram into divers , especially if a diver enters a zone where they have been actively  hunting for fish.  Department of Fisheries regulations warn against any interaction with marine mammals
