Lactuca tatarica: Blue lettuce–The Race Rocks taxonomy

flower blue lettuce

The introduced invasive species Lactuca tatarica appears occasionally at Race Rocks

Cautionary note in case someone gets hungry on the island:

“The milky-sap from this plant, contains a medicinal compound called ‘lactucarium’. It has been used for its pain-relieving, antispasmodic, digestive, urinating-inducing, hypnotic, narcotic and sedative inducing properties If one injests the plant it is used to treat insomnia, anxiety, neuroses, hyperactivity in children, dry coughs, whooping cough, and rheumatic pain. An external dose can even be applied to warts. However, it should be noted that this plant should not be used in these cases excepted by trained professionals. This is because the plant, even in small doses, could lead to death through cardiac paralysis.” (plant-life.org)

Elephant seal moulting

Misery is hauled up between the path and the desalinator bunker, a change from the grassy area west of the boathouse. He is now almost finished his moult and seems to be much more docile these days. He was observed vocalizing loudly this afternoon (perhaps at a seagull that decided to stare him down on the path). The young female #4252 (soon to be named) has been observed hauled up on the island lately (didn’t see her today). She’s been making almost daily trips to the water from the grassy area near the boathouse (compared to Misery who decides to haul his girth down to the water only when the temperature becomes unbearable for his copious amounts of body mass). #4252 seems much more nervous than other elephant seals, perhaps because she is younger and is not as acquainted with our human presence on the island as compared to the other Mirounga. I have not seen Bertha around for a number of days now, and I’ve not seen Slash since my return to the island two weeks ago.

Reaction to DFO Announcement on Selling off its Lighthouses

In June of 2010 a few days after the Heritage Lighthouse Act came into effect, the Department of Fisheries, in charge of Coast Guard, announced that it was selling off all its surplus lighthouses across Canada. Race Rocks was included on the list of 960 surplus lighthouses. Our initial response was ” How could the federal government even think of selling off a heritage structure–the only rock built lighthouse on our Pacific Coast and especially in the year of its 150th anniversary of construction?” We contacted BC Parks for clarification since the Lighthouse is on Provincial Crown Land leased to the Federal government, and therefore it would be hard to see how the tower could be sold. Their response was as follows:
  • ” I looked through our files and confirmed that the lands occupied  by the light are provincial lands under a transfer to the federal government for lighthouse purposes.
    Also our planner David Brown in Terrace has contacted a Pacific Region federal staff member that assured David that DFO/Coast Guard knows that they cannot enter into any arrangement to sell, lease or otherwise tenure out, most of the lighthouses in BC because the land is under provincial ownership. This implies that Pacific Region will simply not act on this initiative where it has to do with the lights that are on provincial land.”

  • DOCUMENTS: 1894 and 1997 re Lighthouse Reversion In September of 2011, I contacted Andrew Anderson in DFO and asked for a clarification based on the above statement. after a telephone conversation, his response is below: September 29, 2011 5:52 AM
    Mr. Fletcher: 
    As discussed – Under the Heritage Lighthouse Protection Act, the Department was required to publish a list of lighthouses deemed surplus to operational requirements. Canadian Coast Guard has determined that ownership of the structure that supports the aid to navigation at Race Rocks is no longer required for program purposes and as such it forms part of the surplus list. The preamble to the list of surplus lighthouses on the DFO web-site acknowledges that despite surplus status there could be administrative or legal issues related to some sites that would restrict the capacity of DFO to transfer ownership.

  • EXCERPT FROM “Heritage Lighthouse Protection Act Implementation, May 2010
    Heritage Lighthouses of Canada

    “Fisheries and Oceans Canada has declared approximately 480 active lighthouses and approximately 490 inactive lighthouses across Canada surplus to its needs. Under the new Heritage Lighthouse Protection Act, these properties can be transferred to new owners wishing to take advantage of their heritage designation or tourism potential.

The Act comes into force on May 29, 2010 as a means to protect federally-owned heritage lighthouses by allowing them to be used for other purposes, as long as they are maintained in a manner consistent with established conservation practices.

Individuals, municipalities or non-profit groups may apply to Parks Canada for heritage designation of any federally-owned lighthouse property. For the surplus lighthouses, a written commitment to acquire ownership and protect the lighthouse must be accepted by Fisheries and Oceans Canada in order for it to be designated under the Act. Potential owners must submit a business plan that shows their proposed use of the property will be economically viable over the long term, and that they have the capacity to manage the property.

In some cases, lighthouses contain aids to navigation, which must remain operational. Parties wishing to purchase these properties would need to enter into an agreement with Fisheries and Oceans Canada, permitting it access to the site for maintenance and operation of the aid to navigation.

Pursuant to the Heritage Lighthouse Protection Act, the Minister of Fisheries and Oceans Canada has determined that the lighthouses on the lists below are surplus to the operational requirements of the Department. A surplus lighthouse may only be designated as a heritage lighthouse if a person or body submits a written commitment to acquire the lighthouse and protect its heritage character in the event that it is designated as a heritage lighthouse.” See continuation in the original version (2010) with Gail Shea as Minister of Fisheries:

For the Current version of this — See this on the DFO website

Note in particular, the following paragraph:from this reference:

“For the surplus lighthouses, a written commitment to acquire ownership and protect the lighthouse must be accepted by Fisheries and Oceans Canada in order for it to be designated under the Act. Potential owners must submit a business plan that shows their proposed use of the property will be economically viable over the long term, and that they have the capacity to manage the property.”

On the Environment Canada website one finds the following version:

Petition Process

You are encouraged to participate in the designation of heritage lighthouses!

Residents of Canada can nominate a lighthouse for designation under the Heritage Lighthouse Protection Act by forwarding a petition to the Heritage Lighthouse Program by 29 May 2012.

To meet the requirements of the Act, petitions must:

nominate a lighthouse that is currently owned by the federal government;
be signed by at least 25 residents of Canada who are 18 years of age or older, including the names and addresses of all petitioners; and
be addressed to the Minister responsible for Parks Canada (the Minister of the Environment).

Elephant seal behaviour

-106, ‘2010-06-03’, ‘Elephant Seal’, 3, ‘An eventful day for the elephant seals. More sunlight and less wind than we ”ve been used to this spring brought all three Elephant Seals on Great Race down to the water… but not before Misery had a go at mounting Bertha. She escaped up the “steep ” path to the grass on top of the foundation left from the original keeper’s house. Bertha then slipped past the sleeping Misery and lay on the ramp right at the water line in the shade but not in the water. Misery woke and detected the deception and came barreling down the path and boat ramp. Bertha took off through the water like a startled harbour seal, moving closer to the hauled-out California sea lions. She did not come back on land until dark. After all his effort, Misery followed just until he was in the water and took to splashing water back across his body which both trickled and steamed off his late winter coat. Once refreshed, he moved further into the water, floating and steaming in the warm sunshine. Seeing/smelling Bertha in deeper waters, he followed her only to have her swim even further away. 4252 was already in the water and Misery soon sensed her and tried to pin her against the rocks in the shallow sea lion haul-out, but she snapped at him and also swam to deeper waters. Just before sunset, Misery returned to land, trumpeting in the shallows. Looking at records -and noting how much girth Misery has put on lately), the habitat use of our two adult bull elephant seals is very different. Misery: showed up for the ”season ” first in October, was back before Slash showed up for the pupping season, stayed longer through the breeding season, and is now here moulting -as he did this time last year). His moult is delayed 1-2 weeks compared to last year. That all said, Misery has grown significantly this season after spending much of the last 6 months here at Race Rocks, while our dominant bull spends much greater times away before returning with added mass.’, ‘ryan’, ’23:56:01 ,

Gulls nesting

Over the last few days, a number of gull nests with eggs have been spotted around the island. By now, most gulls have nested, although there are still a number of pairs that appear to be without nests still. Gull numbers seem to be down compared to the same time last year.
Elephant Seals: Bertha seems to have taken off sometime in the last few days, although Misery and #4252 (soon to be named) are still sticking around. A female elephant was spotted on Middle Race several days ago.

Elephant seal intrigue

Black Oystercatchers are the species of the day with the first chicks sighted in the nest to the E of the Main Keeper’s house. Camera 1 will just be able to make them out if they stay put. Another nest was discovered directly behind tank #1 that is a “limited-time only” infrastructure feature on the island. 3 nests with eggs:3,2,3 (now 2+chicks,2,3), 2 brooding pairs with undiscovered nests, and 2 pairs with overlapping feeding territories but no suspected nest sites.
