Jamieson and Maciek on the island today
Erik + 6 divers, 3 surface tenders, and Laura Verhegge came out for a dive off the jetty
Maciek left for the college with the dive boat

Incident with a tour boat operating over top of the divers, despite a properly posted dive flag and hand signals to back off. Settled it over the radio.
Consider making it policy to call a securite on the radio to inform operators that there are divers in the water.

-A box of supplies was delivered by Erik for a variety repairs
-Scoped out plumbing repairs in the student house
-Started cleaning student house (murdered flies, cleaned windows and sills, vacuumed)
-Ran dealinator
-Practiced docking the boat on the jetty in the evening with the ‘Jamieson School of Boat Handling’

Lots of littluns!

 

Glaucous-winged gull chicks, newly hatched

Glaucous-winged gull chicks, newly hatched

The glaucous-winged gulls have started hatching all over the island. Stressed parent gulls are VERY protective, dive-bombing any passersby. And for good reason because the juvenile bald eagle has paid a few visits in search of lunch.

 

There are generally 3 eggs to a nest although many only have two.

Oystercatcher chicks

Oystercatcher chicks

The oystercatchers on the south side of the island hatched on Sunday mid-morning. Notice the similarly coloured eggshells. Even though the two chicks have different nesting environments, a similar pattern camouflages them in their surroundings. The oystercatcher shells are also considerably smaller in size.

 

Although we’ve had less whale-watchers these past few days, a number of dive boats have visited the underside of the island. Don’t be fooled–the weather might look nice, but the water’s still only 10 degrees celsius!

Sept 15th..up to 175 sea lions

Today I used the new seawater pump to fill the cistern which had gotten pretty low. We de-salinate water here for household purposes as there is insufficient rain and the roofs are quite contaminated with gull poop!

The reserve is busy today with tour boats and divers. I had to call one of the companies to ask their operator to slow down at the edge of the reserve. Usually they are pretty good but occasionally a new driver doesn’t realize the reserve boundaries. More troubling are the recreational boaters who frequently speed through the reserve. The problem is that unless you are a local it is unlikely you will know the guidelines. As much as I dislike signs this seems a reasonable place for a few “5 knots” and ” No Fishing” signs. There is simply no way I can ask them to slow down from my perch on Great Race Island…

The California and Steller sea lions are here in droves. I counted more than 175 Stellers in the reserve. The vast majority are bulls but there are a few cows and in the last few days a number of yearlings have shown up. I will get some pictures for the next entry. The view from the tower shows the commotion outside my house!

Hundreds of California Sea Lions adorn the lawn.

In other animal news, quite a few glaucous-winged gulls remain but i think all the chicks can fly now. A few cormorants have returned and about 50 black turnstones wander about between the sea lions picking off insects. I also observed some type of sandpiper picking insects off a dead gull chick. Very resourceful!

Sea Lions are arriving

Aside

More and more California Sea Lions are showing up. There are about 10 on the rocks beneath the winch house as I write this. This photo however is of two Stellar’s enjoying the sunset after they cleared the rock of Californians.

I noticed three more Red Knots on the foreshore, and a corvus caurinus (crow) made it out for a visit. North-western crows are rare visitors here and I have only observed solitary excursions.

Work this week has comprised of painting the railings around the main house and walkway. We got the water desalinator working again, and some of the old computer equipment was removed from the student house.

Several dive groups have made underwater excursions just off the dock in the last week. We continue to see a lot of tour boats in the reserve.

This afternoon I noticed the first Glaucous-winged Gull egg in a shallow grass nest a few feet from my doorstep. I will have to stick to the sidewalk for a few months while the nesting and hatching play out.

Elephant Seals, Divers

On Wednesday afternoon the elephant seal with double green tags 5086/4665 hauled out again on the boat ramp and has remained around the jetty for the past days.  Today I noticed another elephant seal in the South bay with green tag # 6355.  This appears to be the same one that Mike reported in early January. 

Squall has been over by the fog signal the past two days but made her way back towards the flagpole at sunset today.  According to Pam, Squall turned 9 weeks old today.

Today there were two vessels in the reserve. In the morning Pinnacle Scuba Adventures (they have a video with some nice underwater shots on their site) brought a group out and dove near the jetty.  They paid a visit to the underwater camera and gave the lens a wipe, thanks!

In the afternoon a Prince of Whales ecotour vessel visited the reserve while the current was ebbing into a +25 knot W wind, looked like a bumpy wet ride.

 

boats and planes!

Human Interaction
At 0835hrs PDT a floatplane flew W to E over the south side of the Reserve under 1000 ft.

At 1035hrs PDT a small RHIB entered the east side of the Reserve near North Race at high speed. The vessel proceeded to transit the main passage to the south side of Middle Race where they approached within 30 metres of harbour seals on the Rocks. At least 25 seals took flight to the water.

At ~1100hrs PDT a vessel was spotted entering the Reserve from the east at high speed.

At ~1330hrs PDT a vessel was spotted transiting the main passage at very high speed. Communication was made with the vessel and it slowed.

At 1510hrs PDT an Oak Bay Marine Group vessel was spotted fishing within the limits of the Reserve. Pedder Bay Marina was alerted. The vessel was halted by another recreational fishermen before PBM staff could respond.

At 1515hrs PDT an OBMG vessel was spotted speeding in the waters west of Great Race. The vessel eventually departed.

At 1515hrs PDT a recreational vessel was spotted fishing near West Race. The station vessel was launched to intercept the violators and they departed shortly thereafter.

At ~1900hrs PDT a recreational vessel was spotted speeding into the eastern portion of the Reserve in the direction of the North Race-Middle Race channel. The vessel slowed before entering the channel.

Divers from Ocean Educations arrived in the afternoon to dive off the front side of the island.

There were 18 visitors to the island today.

Pseudocnus curatus: Black brooding sea cucumber–The Race Rocks Taxonomy

 

 

by Ryan Murphy, April, 2010 See Ryan’s underwater set on Flickr with a range of invertebrates:

In the early 1980’s while doing subtidal surveys, we discovered a major concentration of the small subtidal sea cucumber Pseudocnus curatus ( formerly Cucumaria pseudocnus) living in high density off the West side of Great Race Rocks. On April16, 2004, six divers, Ramiro, Mael, Mike, Carmen, Aven and Chris were able to do a preliminary survey of the area and have produced the results shown here.
To do the survey, they ran out a reel tape measure from shore to 75 meters in a bearing of 255 degrees magnetic from peg number 7- a permanent reference peg on the very South West corner of the Island. This took them into water that is 8 to 10 meters in depth.
We are uncertain as to why this organism concentrate here in these numbers, and this also happens at other locations such as Beecher bay 3 km to the West. This is the only area we find them in at Race Rocks.
Also included in this file are the raw data values from the divers. One may clip and paste these into an EXCEL program in order to do alternate analysis.

This species is distinguished from Cucumaria pseudocurata which lives up in the mussel beds by having 10 tentacles instead of 8. It is s found in great abundance on the surface of boulders at a depth of 10 meters 60 meters offshore of the south west tip of Great Race Rock ( peg7) Counts of up to 1000 per square meter have been estimated. It can also be found intertidally among the mussel beds on the Western side of the main island.

The following count done by students of the diving activity gives an idea of how dense this species is in one location at Race Rocks. Recently Ryan Murphy found another population of this density on the Eastside  of Great Race Rock.
The book Sea Cucumbers of British Columbia, Southeast Alaska, and Puget Sound by Phil Lambert is the best source for identification of most of the 45 species of local sea cucumbers. In it he notes that the habitat of Pseudocnus curatus “in the Juan de Fuca Strait tends to be shallow subtidal in areas where the tidal currents are strong….. They nestle together in large aggregations on open rocky surfaces …..and….. are eaten by many species of sea stars……although their body wall is toxic to some fish predators providing a strong defense mechanism.”

See also Taxing Problems by Philip Lambert – Now Curator Emeritus of Invertebrates, Royal BC Museum for a description of the difficulty in classification and the need to classify by the skin ossicles.
Google Pseudocnus curatus for a link to the page describing this species..

Pseudocnus curatus Is similar to another species, Cucumaria pseudocurata which is found more shallow in the intertidal zone at Race Rocks. Both species average 1.5 to 3cm in length. C. pseudocurata has 5 bands of tube feet in single or zig zag rows. As a rule there are 8 equal sized tentacles. P.curatus on the other hand has 10 equal sized tentacles. and tube feet scattered on the Dorsal side. At Race Rocks, it lives in the subtidal zone at 8 to 10 meters in depth.

The Johan Ashuvud Memorial

It is unlikely that the creation of the Race Rocks Ecological Reserve in 1980 would have happened except for the efforts of an 18 year old Pearson College student from Sweden.

johan Johan Ashuvud, a student from 1978-1980, was in the Marine Science class and the Diving Service as part of IB his program at the college.
He devoted a great amount of energy in helping to direct a group of students in an extensive diving and research program in order to demonstrate the need for a Reserve at Race Rocks.

dv1Johan Ashuvud SCUBA diving at Race Rocks 1979

 

 

 

ellisIn the fall of 1979 he helped organize a workshop to investigate the creation of a reserve at Race Rocks involving provincial and university officials. Johan was instrumental in drawing up the draft proposal with staff of the Ecological reserves branch of the Parks Department in the provincial government and even helped in guiding the Deputy Minister of Parks on an underwater tour of the reserve.

sw4mJens Jensen from Denmark,and Johan Asuvud attach a transect line onto the top of the rarely exposed Rosedale Reef, South of Race Rocks at an extreme low tide.  At that point they were standing on the most southerly point in Western Canada!

Jballanac27-1ohan’s underwater photography was the first done by students of the college and was to become very valuable in helping to promote conservation of the beautiful life forms there
A gallery of some of his work is available here.

celeb80When the Ecological Reserve at Race Rocks was declared in 1980 by the provincial government, the group of students who had worked on the proposal made a celebratory trip to Race Rocks to tell the lightkeepers Trev and Flo Anderson of the great news. (Johan is on crutches after returning from a holiday in Mexico where he had had a collision with a bus!)

sw7A few weeks later, Trev and Flo invited the core group back to present the “Order of Race Rocks” for the great work done. Johan (center of photo) and other divers with whom he had worked, were given the special presentation by Trev and Flo Anderson to express their thanks for the work done.
When Johan graduated from Pearson College, he went on to the School of Economics in Stockholm, Sweden, where he obtained his Master’s degree in Environmental Economics. His first job was in Costa Rica with the International Union for the Conservancy of Nature (IUCN). There he continued his interest in getting special places preserved, as he worked to convince officials in Parks Departments of Central American governments to preserve their Natural Heritage.

Almost 10 years after he left Pearson College, on a trip back to Sweden in April of 1988, Johan died in a car accident. Our college community was deeply saddened by this tragic event. Johan left his wife and a soon to be born daughter.
Johan would be the first to urge young people from all countries to never give up with environmental concerns. He proved to us that youth can make a significant impact in the world by getting actively involved in working to preserve such special places as Race Rocks.

In 2000, The family of Johan contributed the Johan Ashuvud Memorial Fund to be administered in Trust by Lester B. Pearson College . The purpose of the fund is to support with the annual proceeds environmental activities, research and projects undertaken by present and former students of Pearson related to the Race Rocks Marine Reserve.

  • In June 2000, Several students with faculty member Garry Fletcher did a week-long series of webcasts from the Ecological reserve for the Johan Ashuvud Week
  • In June 2001, students Damien Guihen and Jean Olivier Dalphond spent several weeks at Race Rocks, doing webcasts, and producing QuickTime Virtual Reality and QuickTime Videos for the archives of racerocks.com.
  • In June 2002 four students are doing an educational webcasting program from Race Rocks.
  • Almost every year since 2002, a few students from the college stay behind after others leave at the end of the term in May to go to Race Rocks for a project week which we still call “The Johan Ashuvud Week”

One of the last papers published by Johan on his work for the IUCN in Central America :

Ashuvud, Johan, “Environmental Conservation for Development in Central America” C. Folke and T. Kåberger ed. Linking the Natural Environment and the Economy: Essays from the Eco-Eco Group, (Boston, MA: Kluwer Academic Publishers, 1991): 253-270.

ASACODE, Asociación San Migueleña para la Conservación y el Desarrollo, tiene un Albergue para la recepción de turismo en una finca dedicada al manejo integral del bosque, que fue donada por UICN y que lleva el nombre de Johan Ashuvud.

*” Talamancan Ecotourism and Conservation (ATEC) Association, provided training Tourism naturalist guides, who work in Talamanca (local communities). ATEC works as tour operator working directly with the community. * ASACODE, San Miguelena Association for Conservation and Development, has a Hostel for receipt of tourism in an area dedicated to integrated forest management, which was donated by IUCN and named Johan Ashuvud. * There are a number of private initiatives to develop tourism hotels which will generate pressure on the resources of the Refuge.”

In December 2014,  a memorial bronze plaque was installed at Race Rocks to commemorate Johan and the work that he did to help in the creation of the Race Rocks Ecological reserve: Click to enlarge.2014-12-28johanplaque

The plaque can be seen from the remote camera 1. It  faces the tower on the rock near the path intersection below the tower.
