This is a very small dorid nudibranch, 15 mm in length, with elongate orange-tipped club-shaped tubercles around dorsal margin. Rhinophores are bright red-orange.
We haven’t photographed this nudibranch before, but due to its small size it has probably been overlooked until now.

Lighthouse team disputes right to sell Race Rocks

Lighthouse team disputes right to sell Race Rocks operators say beacons not owned by federal government

OTTAWA — With the federal government preparing to sell almost 1,000 lighthouses across the country, the group overseeing operations at the beacon on Race Rocks, off Vancouver Island, says many are not the government’s to sell.
At issue is who holds the rights to the land — the respective provinces or the federal government.
The lighthouse at Race Rocks, one nautical mile below the southernmost tip of the Island, was built by the Royal Navy in 1860.
It has been listed as “for sale” since June, when the government designated it and the others as surplus property. The tower stands on a rock within an island that is part of a provincial ecological reserve.
While the tower is owned and operated by the Canadian Coast Guard, the land on which it sits is not federal property, a spokesman for the province said Thursday. “The land occupied by the lighthouse on Race Rocks is provincial land, which is under a transfer, or lease, to the federal government for lighthouse purposes,” said Dan Gilmour, a spokesman for B.C.’s environment ministry.
In a letter to the Race Rocks team after the lighthouse was designated surplus property, Gilmour’s colleague, Doug Biffard, said he had received notice from the federal government indicating it was aware of the quandary.
“The Department of Fisheries and Oceans and the coast guard know that they cannot enter into any arrangement to sell, lease or otherwise tenure out, most of the lighthouses in B.C. because the land is under provincial ownership,” the letter said.
Last summer, the federal DFO published a catalogue of 975 surplus properties following the coast guard’s assessment of all the lighthouses it operates.
The list contains at least one from every province except Saskatchewan. To save the lighthouses listed as surplus, a community or group must agree to take on the maintenance of the site, but the federal government would continue to operate and maintain the lighthouse.
The government was criticised when the listing became public in June. Many groups said it undermined the Heritage Lighthouse Protection Act, which had come into force days earlier. The act was designed to ensure the federal government preserved historically significant lighthouses, rather than leave them abandoned.
Those feelings were echoed by the chairman of the Senate committee on fisheries and oceans, Liberal Sen. Bill Rompkey.
This week, the committee released the first of two reports on lighthouses.
When the committee toured the country and hosted discussions on the future of lighthouses, it heard from some of the stakeholders at Race Rocks, including Garry Fletcher, B.C. Parks Ecological reserve warden.
“It would defy logic to see how the federal government could sell a property owned by the province,” Fletcher said.

Feds’ lighthouse sell-off program hits dark patch

Feds’ lighthouse sell-off program hits dark patch

OTTAWA: The federal government has been preparing to sell almost 1,000 lighthouses peppered across the country.

But many of those beacons aren’t the government’s to sell, says the group overseeing operations on an island in British Columbia where one of those lighthouses sits.

At issue is who holds the rights to the land : the respective provinces or the federal government.

The lighthouse at Race Rocks is located one nautical mile below the southernmost tip of Vancouver Island, and was built by the Royal Navy in 1860.

It has been listed as “for sale” since June, when the government designated it and the others as surplus property.

The light tower which harbours an automated light and a foghorn stands on a small rock within an island that is part of a provincial ecological reserve.

And while the tower itself is owned and operated by the Canadian Coast Guard, the land on which it sits is not federal property, a spokesman for the province said Thursday.

“The land occupied by the lighthouse on Race Rocks is provincial land, which is under a transfer, or lease, to the federal government for lighthouse purposes,” said Dan Gilmour, a spokesman for B.C.’s environment ministry.

In a letter sent to the team at Race Rocks shortly after the lighthouse was designated surplus property, Gilmour’s colleague, Doug Bifffard said he had received notice from the federal government indicating it was aware of the quandary.

“The Department of Fisheries and Oceans and the Coast Guard know that they cannot enter into any arrangement to sell, lease or otherwise tenure out, most of the lighthouses in B.C. because the land is under provincial ownership,” the letter said.

Last summer, the federal Fisheries Department published a catalogue of 975 surplus properties following the coast guard’s assessment of all the lighthouses it operates.

The list contains at least one from every province except Saskatchewan, and includes some iconic structures, such as those at Peggy’s Cove, N.S. and Cape Spear, near St. John’s, N.L.

To save the lighthouses listed as surplus, a community or group must agree to take on the maintenance of the site, but the federal government would continue to operate and maintain the lighthouse, itself.

The government took some heat for the move when the listing became public in June. Many groups said it undermined the Heritage Lighthouse Protection Act, which had come into force days earlier, at the end of May.

The act was designed to ensure the federal government preserved historically significant lighthouses, rather than leaving them abandoned and left to crumble.

Those feelings are being echoed by the chair of the Senate committee on fisheries and oceans, Liberal Senator Bill Rompkey of Newfoundland and Labrador.

“We were disappointed and surprised that the coast guard had made so many lighthouses surplus,” he said. “It really defeats the purpose of the act.”

The committee this week released the first of two reports it is issuing as part of its wide-reaching study of Canadian lighthouses.

The second report, set to be released this spring, will focus on the heritage aspect of the country’s lighthouses, Rompkey said.

One issue the committee will examine closely is how much time a community group has to assume responsibility of any given lighthouse, Rompkey said. As it stands, groups have two years from the day the act came into force.

“We feel they really should revisit that part, at least,” he said.

When the committee was touring the country and hosting discussions on the future of lighthouses, it heard from some of the stakeholders at Race Rock, including Garry Fletcher, BC Parks Ecological reserve warden.

“In my opinion, it would of course, defy logic to see how the federal government could sell a property owned by the province,” he said. “And we conveyed this sentiment when we attended the Senate meetings in Victoria.”

Military Activities Near Race Rocks

DND BLASTING ACTIVITIES AT ROCKY POINT:

  • blast-18Bentinck island is used by the Department of National Defense as both a demolition range and a testing range for explosives. On the South end of Rocky Point there is a disposal pit where other demolition occurs, and in Whirl Bay, behind Christopher Point, there is an underwater test site. The size of the explosions is supposed to be monitored and controlled , however, we invariable get widely varying impacts. Our ecoguardians have made observations of the impact on sea
    agornge-1

    From the “burn pit” on Rocky Point

    lions, seals and seabirds over the last few years. Invariably the blasting results in the sea lions being scared from the islands . Sometimes they do come back to haul out on the rocks but they often move on to another location. Unfortunately the location of Race Rocks next to these areas makes it very difficult to mitigate the impact of these explosions.

  • This video was made on October 7, 2002 in order to document the effect of the dndblasts-1Department of National Defence demolition exercises on Bentinck Island on the behaviour of birds and marine mammals at Race Rocks MPA. In previous years we have observed considerable disruption by military exercises involving blasting on nearby Bentinck Island in the fall just after the sea lions have returned to the island. We have requested that blasts be spread out over a longer period of time during an exercise. Traditionally blasts have come in a series of three. The first one would alert the sea lions, the second would send a few in the water and the third would clear the islands. This year on this one occasion, only two blasts were held at five minutes apart. The results are shown in the video.
  • On November 7, 2002, the DND were still doing their demolition blasting exercises at Bentinck Island. (not Oct 7 as stated in this draft version of the video) The students lionblasts-1from Lester Pearson College who were out for a project week were able to catch the images of the impact of these blasts on the first day from the science centre window and on the second day from the top of the light tower. In the tower, they interviewed Mike Demarchi of LGL who is currently doing a $50,000 contract for the Department of National Defence to monitor the impact of these blasts and to compare them with other disturbances at Race Rocks.

Update 2020: and its still going on —-https://www.racerocks.ca/tag/blasting/

and on January 27-2020: another set of blasts from Bentinck Island clears the docks of sealions:

https://www.racerocks.ca/wp-content/uploads/2020/01/Blasting.mp4“][/video]

Recommendations:

1. Explosions should only be conducted at times of the year when there are no nesting birds or harbour and elephant seals having young .
( this occurs May to mid-August for harbour seals and mid-january to February for elphant seals )

2. During the months of August, September and October when the sea lions are returning to the islands, they are particularly sensitive to disturbances.

3. December, March and April are probably the times of least impact but only if explosion size is carefully controlled.

4. The sizes of explosions should be carefully monitored so as to limit the impact of disturbance.

5. Blasts should be spaced out to at least 10 minutes between detonation, and especially never three blasts in succession. This lessens the impacts on the animals.

SAMPLE DAILY LOGS FROM RACE ROCKS WITH EFFECTS OF BLASTING ON ANIMAL BEHAVIOUR

Thursday, November 22, 2001–MARINE LIFE: A typical November day weather wise however the Military detonation exercises on Bentinck Island were particularly disturbing for the Harbour Seals and Sea Lions. Once the blasting was done for the day the animals were still quite nervous and in fact when a Cuda Marine Whale Watching boat went by one rock (15:15-15:30) with approximately 120 sea lions hauled out over half of them stampeded into the water!”

Thursday, January 17, 2002
MARINE LIFE:At 8:30 there were 150-170 Sealions, 2 large bull and 1 smaller Elephant Seals on Middle rock. With the first blast at 11:10 the gulls and cormorants took flight, most of the sealions were alerted and some went into the water. When the second blast went off 2 minutes after the first, the sealions scrambled over each other in a rush to get to the water. The elephant seals although alerted (raised their heads and looked around ) did not move off their spots. With each blast the eagles, gulls and cormorants all took flight but within 1 or 2 minutes settled back down. During the hour between blast series 10 to 15 sealions hauled out again but appeared to be somewhat ‘edgy’ and were much quicker to move into the water when the blasting occurred again. There were 14-7 mature Bald Eagles in the M.P.A. today.

Friday, January 18, 2002
MARINE LIFE: At 8:30 there were only 75-80 sealions hauled out on middle rock, not all the animals have returned since the blasting yesterday. The first blast at 9:58 alerted all the sealions and 20-25 went into the water, the second blast 2-3 minutes later sent all but 6 animals scrambling into the sea. The last blast at approx. 10:25 sent 12 of the 20 sealions that had hauled out after the 10:01 blast, back into the water. There will be blasting exercises again next week on the 24th and 25th. There were 11 (7 mature ) Bald Eagles today.
posted by Carol or Mike S at 6:03 PM

Thursday, January 24, 2002
MARINE LIFE: Today we monitored the scheduled detonations at the D.N.D. site on Bentinck Island. There were three sets of blasts, each consisting of two detonations separated by about 2 minutes. The first blast at 10:54 sent the gulls, cormorants into the air and alerted the sealions hauled out on the middle rock. About 20 animals moved towards the water then the second blast went off and caused a stampede of all the hauled out sealions. The birds as usual settled back down in a minute or two. Very gradually a few at a time, 10-15 sealions returned to the haul out areas. The Elephant Seals raised their heads and looked around but did not move away. The Second set of blasts at 11:53 and 11:55 cleared Middle Rock of sealions and also sent 40-45 Harbour Seals hauled out on the western slopes of the Southeast Rocks scrambling into the water. The Last 2 blasts( 12:48 and 12:50 ) sent the 5 sealions that hauled out again about 20 minutes after the 11:55, back into the water. Do not know the size of the detonations but they shook the cameras and most of the pictures on the walls. There are more blasts scheduled for tomorrow. There were 7 Bald Eagles – 4 mature.

Addendum:
In the fall of 2002 the blasting activities took place again at Bentinck Island. This year we have had a large population of the endangered Northern Sea Lions, and are again at risk of having them move out due to the effects of the blasting. The DND has let a contract for an environmental study to LGL, an environmental consulting firm ( See link below). Unfortunately the results of that study will not affect the pattern of blasting scheduled for the fall term. We have been recording the effects with several videos and images below.

UPDATE: January, 2007: Recent blasting activities at Bentinck Island have flushed some of the birds and have scared some of the northern sea lions into the water. In general however we have observed that when they only do two blasts at more than a 1 minute interval, there is much less disturbance than three successive blasts.

Nereocystis luetkeana- Videos of Kelp

 

Kelp and color. At the end of a live underwater video session, I inadvertently left the camera “on while I was waiting in the kelp bed off the jetty at Race Rocks Ecological Reserve.  It was a sunny day and the effects created by the sunlight streaming through the canopy of the forest gave this interesting effect.” GF-2003

Note: The video pauses on each clump in order to have a better view.

When Race Rocks was declared Canada’s first Marine Protected Area, Holly Arntzen offered Pearson College the opportunity to use some of her songs as video backgrounds. Her CD entitled “The Salish Sea” is about the fading beauties of the oceans and it stresses the importance of their protection.
Using the song “Saltwater” as a background, this video shows images of divers and the bull kelp, Nereocystis leutkeana, a species of brown algae present in high density throughout the summer and fall at Race Rocks. Their lamina provide a special protective canopy for a delicate ecosystem with many species of invertebrates and fish under their canopy. This video was filmed and edited by Jean-Olivier Dalphond (PC yr26) and Damien Guihen (PC yr27) in June 2001.

The background color can be white or any shade of yellow to a yellowish brown, and it has characteristic markings consisting of a few brown rings or irregular spots. Specimens with more numerous spots are Diaulula odonoghuei.” Wikipedia

Barred Owl at Race Rocks , November 2010. Images by Raisa Mirza

Raisa Mirza (Ecoguardian) took these photos of the first Barred Owl to be photographed at Race Rocks on November 2, 2010. Raisa notes: ” When I woke up this morning, Virginie said that she had seen an owl and taken a picture which was pretty awesome. Lo and behold when I went outside half an hour later, I spotted this Barred Owl behind the boat house. He was covered in mist. This picture was taken later in the day when the sun had come out. My first owl sighting in the wild ever! I’m pretty excited to share the other shots of him. Couldn’t wait to put this one up. Another first sighting at Race Rocks! Its pretty awesome to know that my photography is contributing to building a cool record.”

The barred owl is a permanent resident of nearby Southern Vancouver Island, It is frequently heard at night in the farms and wooded areas of Metchosin.

In this photo by Raisa, the barred owl has its head turned 180 degrees and it is looking to the left on this photo.  The wind pushes up the feathers on the back of the head giving it a very weird appearance!
