Many Seals, Census

Weather:

  • Visibility 10 + NM
  • Sky partly cloudy
  • Wind 15-20 Knots SE
  • Sea state: calm, rippled

Marine Traffic/Visitors: One pleasure craft drifted through in the early afternoon. They did an amazing job of drifting with the current so the animals would not be disturbed, and were very careful of the kelp and shallow areas. Well done!

Ecological: 

  • The animals have been keeping to themselves and trying to stay out of the elements as yesterday there was quite a bit of rain and wind. When the weather is harsh, the elephant seals typically try to lay behind a rock or outbuilding to avoid the wind. The seagulls point themselves into the wind and sit close to the ground. The sea lions don’t seem to mind at all, but the geese love the rainy days! They like to drink from puddles and clean their feathers in the fresh water.
  • Yesterday we were visited by a flock of pigeon guillemots, who prefer the jetty or rocks immediately surrounding.
  • Comments in photos refer to pineapple weed..check it out here in the Taxonomy File

Census:

  • 7 Elephant Seals
  • 8 Oyster Catchers
  • 32 Sea Lions
  • 101 Harbor Seals
  • 22 Geese (one active nest)
  • 285 Seagulls

 

Stunning Weather, Spring at Full Force!

Weather:

  • Visibility 15+ NM
  • Sky clear
  • Wind 5-10 knots SW
  • Sea State: calm

Marine Traffic/Visitors:

  • 2 jet skis yesterday evening, 1 kayak this morning, 1 eco-tourism vessel yesterday
  • Greg today with supplies (thanks Greg!)
  • 1 boat inside the reserve fishing this morning- Greg stopped to remind them that they were within the boundary on his way
  • Many pleasure crafts just outside of the reserve boundary

Ecological: 

  • Consistent eagle presence as the seagulls continue to return, and food is plentiful in the water
  • The geese seem to be getting pushed out of their territory by the seagulls. The seagulls have continued to steal goose eggs when they get an opportunity, thus there are only 2 remaining nests with eggs. The geese have started to spend more time on the water, and often leave during the day.
  • The pineapple weed has been growing at an impressive rate! Most of the grassier areas on the island are covered by the fluffy foliage.

 

Matricaria discoidea : pineapple weed, The Race Rocks taxonomy

The observation below was made in 2013/06/05 …

Several large areas where the grass was matted and smothered by the sealions hauling out last fall, now have a prolific growth of this newly arrived plant, Matricaria discoidea, or pineappleweed. These are the tallest growing samples of that plant I have seen. Another plant in the same areas is the fiddleneck, Amsinckia menziesii

This year the same situation appears in the areas trampled by the sealions last fall. This post  shows how comfortable it is for the elephant seals.

Kingdom: Plantae
Clade: Tracheophytes
Clade: Angiosperms
Clade: Eudicots
Clade: Asterids
Order: Asterales
Family: Asteraceae
Genus: Matricaria

A trip with BC Parks Staff to Race Rocks

On the morning of Wednesday June  6 , I went with Andy MacDonald,  the Vancouver Island Region (South) Parks and Protected Areas Section Head, and  Zsana Tulcsik, the new BC Parks Area Supervisor from the Goldstream Office out to the Race Rocks Ecological Reserve. ( A report by Garry Fletcher, Race Rocks ER warden)

College staff member Erik Schauff skippered Second Nature and we met Chris Blondeau , Director of Operations for Pearson College UWC  on the jetty. He is the relief ecoguardian at  Race Rocks for the week .

The elephant seals co-operated and were basking in the sun on the grass in the centre of the island. There were 4-  2 year olds and one large older Male, which may have been Chunk … the inflamed  right eye from an injury administered by Misery was a good identification mark.

Two Northern sea lions were observed in the water . I thought it was notable that there were very few harbour seals which usually have pups at this time of year, and none on the southern islets where they usually haul out. I will have to check over the next few days on the tower camera, as they may have been out foraging.

The glaucous-winged gulls are well into nesting season, with several nests containing three eggs. The image from the window of the science centre shows the distribution of pairs. Another picture above shows a nest precariously close to the elephant seal  haulout spot.

There was an abundance of pigeon guillemots on all corners of the island where they have their nesting burrows. They should be visible on camera 5 now out near the edge of the cliff to the west.  They have certainly been a success story in increasing numbers in the past few years. There must be well over 60 pairs nesting in the hidden burrows under the rocks. Ironically good habitat has been produced in several areas because of  human activity in the past by the blasting  of rock for the helipad construction by the Coastguard, and other construction on the islands done in the 1900s before it was an ecological reserve. This is a rare example of habitat enhancement that humans can claim, as usually it is the other way around.

On the return to the docks we were impressed with the clumps of Thrift in full bloom. Chris mentioned that the Black Oystercatchers had been in the area on the rock right off the sidewalk by the docks and we soon spotted the nest. This is the same area they have used for many years. The videos of the hatching oystercatchers in this link  are from the same area.

In addition to the vast monocultures of pineapple weed as shown above, this is the second year we have noted large patches of Fiddleneck, Amsinckia spectabilis in the same compacted and richly fertilized areas where the grass was killed out by the sealions and intense Canada Goose grazing.
