The Future for our Elephant Seal Population?

British Columbians can take great satisfaction in the fact that an Elephant seal colony is being slowly established in British Columbia, and we can see an elephant seal pup being nursed via a webcam on an island within site of Victoria.  The reality is that the risks these animals face in the Strait of Juan de Fuca if they are to maintain a population increase are now becoming even more challenging.

Currently about 6,000 large commercial vessels transit Canadian and U.S. waters toward Vancouver or Washington ports each year. Each month about five large oil tankers ply the waters down the international border within a few kilometres of the Race Rocks Ecological Reserve.

Under the Kinder Morgan Pipeline Proposal, up to 34 tankers a month would be loaded with oil at a terminal outside Vancouver, then travel through Haro Strait and the Strait of Juan de Fuca for export to markets in Asia and the U.S.  These are tankers in excess of 200 metres in length. 

The $5.4 billion expansion project would nearly triple pipeline capacity from about 300,000 to 890,000 barrels of crude oil a day to meet customer demand. Much of that future cargo will likely be diluted bitumen from Canada’s tar  sands. If approved, the expansion is expected to be operational in late 2017. The pipeline is operated by Kinder Morgan Canada and owned by Houston-based Kinder Morgan Energy Partners LP.

The potential of collision and oil spills is unparalleled, and you can’t’ clean oil off a two ton marine mammal very easily let alone the volumes of marine life it consumes daily for survival. It would be a miracle indeed if we still have elephant seals at Race Rocks in 2020, the 40th anniversary of the Ecological Reserve.

References we could all consider seriously:

  • Financial Liability for Kinder Morgan – Georgia Strait Alliance,

    “Residents of the Salish Sea region—Vancouver, Victoria, the Gulf Islands and Washington State—could see a four-fold increase in the number of oil tankers traveling from the Port of Metro Vancouver through Juan de Fuca Strait, if Kinder Morgan is permitted to build a new pipeline to carry oil from the tar sands to markets in Asia. Such a dramatic increase signals exponentially higher risk of oil spills and raises many questions about what is at risk, how the oil is “cleaned up”, and who pays for oil spill response. “

  • The Deepwater Horizon Oil Spill and Marine Mammals by the marine mammal Commission, an independent commission of the US government
  • Effects of Oil Spills on Marine and Coastal Wildlife“Oil spills can impact wildlife directly through three primary pathways: —ingestion – when animals swallow oil particles directly or consume prey items that have been exposed to oil .—–absorption – when animals come into direct contact with oil inhalation – when animals breathe volatile organics released from oil or from “dispersants” applied by response teams in an effort to increase the rate of degradation of the oil in seawater. ——inhalation – when animals breathe volatile organics released from oil or from “dispersants” applied by response teams in an effort to increase the rate of degradation of the oil in seawater”
  • Effects of Oil Pollution on Marine WIldlife ”  Seals are very vulnerable to oil pollution because they spend much of their time on or near the surface of the water. They need to surface to breathe, and regularly haul out onto beaches. During the course of an oil pollution incident, they are at risk both when surfacing and when hauling out.”

kayak disturbance, tagged e-seals, pup, etc

Wind has varied between W and NE less than 20 NMPH over the past few days.  We have had some patches of fog during the week and partly clear skies today and yesterday.

On the 15th a group of 20 kayakers passed through the reserve on the East side heading West.  They passed on both sides of East rock and caused one of the largest sea lion disturbances I have seen here, several hundred sealions scrambled into the water.  I was able to talk to one of the kayakers as they passed by the south side and told him that they are not allowed to cause this kind of disturbance to marine mammals at race rocks. Though I love kayaking and prefer kayaks to motorized vessels, kayakers need to realize that because they are so nice and silent they can also easily surprise wildlife.  Once startled sealions stampede and can easily trample younger sealions or injure themselves rushing over the jagged rocks.

1 dive boat in the reserve today, 1 eco tour in the afternoon, 1 sports fishing boat in the morning which traveled too close to sealions on the East rocks. I called Pedder Bay Marina and gave them the ID number and a description and asked them to talk to the operator about regulations at Race Rocks (thanks Pedder Bay Marina!).

The elephant seal pup seems to be in good shape and is drinking milk regularly. Chunk seems fairly well behaved, a few times a day he we will arise from his slumber and chase after Bertha. Sometimes it seems he is trying to separate her from the pup and restrain her. I have seen him with his mouth around the pup’s head as well as with the pup partly underneath him though on all occasions I have observed he has clearly not harmed the pup when he easily could have. Chunk went off the island last night, I assume to middle rock and was back in the morning. There are two elephant seals on middle rock, both fairly large, one possibly a young male. I have been hearing what sounds like a male’s call coming from middle rock today. There were also two smaller scruffy, moulting female elephant seals in the shoreline of the main island today one tagged green 7502 the other tagged pink N93_ the last number is not visible. That brings the current e-seal population to 7.

Past week maintenance:
-cleaned solar panels daily
-flushed media filter on desal
-changed pre-filters on desal
-troubleshooting cam 5 with help from Jonathan, replaced POE unit. took measurements to replace leaky cable housing at base of cam stand
-ran desal x2
-ran fire pump
-replaced leaky hydraulic line on crane, pressure tested line
-cut, chopped, stacked fire wood
-replaced fire extinguishers which had been sent in for annual servicing
-brought temporary fire extinguishers off island for servicing
-troubleshooting of failed internet system with help from Jonathan
-swapped out 1 propane tank on main house

Visitors this week:
-on the 15th Erik came with a guest to drop off supplies
-on the 16th Erik brought Jonathan out to replace switch in the tower as well as the Marine sciences class for a field trip (12 students and Ann)

Elephant Seal Pup Losing the Wrinkles

Comparison of screen captures from the remote camera over the past 2 days shows that the pup must be nursing well as his wrinkled skin is gradually becoming filled in. The mother will lose up to 40% of her weight while nursing. She will stay with the pup, not returning to the water for several weeks. At that time the pup will have increased in weight and have the adequate fat storage to last it several weeks before it goes to the water on its own and starts to feed.

An elephant seal pup is getting used to the watchful eye of the Internet.

Its every move is being broadcast by a webcam to people watching around the world.

It was born in the early morning hours of January 14 at Race Rocks Ecological Reserve in the Strait of Juan de Fuca just off the southern tip of Vancouver island.

The reserve says this is the fifth pup born to a female called Bertha since January 2009.

Race Rocks is the only place in Canada where elephant seals breed and while other baby seals have been born on the reserve’s other islands, they’ve been washed out to sea by the waves.

Elephant seals were hunted to near-extinction in the 19th century, but are now protected under the Fisheries Act.

Elephant seals more durable than internet networks

I  checked on the pup briefly this morning (so far unnamed as we will wait for a while to make sure he has a good chance of survival.)  I said “he” because Alex thinks it is probably a male because of a tell-tale opening midway from umbilical to tail.

Pup- 2014-01-15 at 11.10.50 AMThis picture taken at 11:15 AM from camera 1 shows all is well and the male Chunk (top) is not bothering the pup or the female. 

 

 

Hopefully you can take advantage of the documentation we have on the website of our observations of elephant seals at Race Rocks Ecological reserve.……more tomorrow…..

Elephant seal Pup at Race Rocks Jan 15, 2014

These are images taken yesterday of the new elephant seal pup at Race Rocks . (by resident Ecoguardian Alex Fletcher). The pup has been nursing regularly and the male “Chunk” is not bothering it so far.

An elephant seal pup is nursing at its mother’s side at Race Rocks Ecological Reserve, oblivious to the fact a camera is sending its image around the world.

The pup was born Monday evening — the first birth of an elephant seal this year on the main island, said Garry Fletcher, educational director for the reserve’s website.

Another elephant seal was born last week on one of the smaller islands but rough weather washed it into the sea where it perished.

“All the ones that are born on the outer islands get washed off,” Fletcher said Tuesday. “This one is from a mother that’s had young ones there four or five times before.”

Race Rocks is the only spot in Canada where elephant seals breed, Fletcher said. Normally, elephant seals choose breeding colonies in Oregon or northern California.

There are usually a few elephant seals hanging out at Race Rocks throughout the year, Fletcher said. Last June, a record high of 15 elephant seals were counted on the reef.

Elephant seals are far out-numbered at Race Rocks by their cousins, California sea lions and northern sea lions. Males can grow to four metres in length and weigh 2.3 tonnes, more than a average car, and are often twice as big as male California sea lions.

Harbour seals, which are smaller and much more commonly seen along the coast, also use Race Rocks to breed.

The numbers of elephant sea lions are rebounding after being hunted to near extinction by the end of the 19th century. Elephant seals are now protected under the Fisheries Act.

Westerly

Over the past 5 days we have had strong westerly winds reaching over 40 NMPH most days (in the evening) and over 50
NMPH on Saturday evening. There have been heavy swells as a result. Because of bad weather/low light I am having to run the generator longer most days, around 3 hours to charge batteries, than usual.

Chunk has mostly remained on main island with Bertha who continues to resist his advances. We are approaching the date when she gave birth two years ago. I have not been able to see the pup on middle rock for several days. The weather has made it harder to get a view over there.

On Thursday the 9th, 12 bald eagles were observed in the reserve. Still havent been able to get banding info on black oyster catchers.

Wednesday, Jan 8th: 1 charter fishing boat toured through reserve, 1 CG helicopter flew over.
Monday, Jan 13th: 1 CG helicopter flew over.
