Sonny Saturday.

The west wind blew 20 – 25 knots all day, bringing cloud, drizzle, rain and eventually, late afternoon, sunshine. The strong wind warning remains in effect and the barometer, which has been hovering above 1010 HPa., has started to drop very gradually. The forecast for tomorrow calls for a mix of sun and rain.

Identifiable, commercial tour boats in the Ecological Reserve were limited to five whale watching boats and one dive charter, today. Two Sea Doo- type vessels, came from the direction of Victoria, did a tour around Race Rocks, and headed back.

Luxuriant growth of Pineapple Weed, Matricaria sp. has filled in the highly disturbed areas where hundreds of sealions hauled out last fall and winter, compacting the soil and destroying all vegetation. Although considered a weed, the pineapple smell is nice and covers up the devastation left behind by the sealions.

Tall pineapple weed covers the area occupied by sealions last fall and winter.

Another species left over from the old gardens here, is blooming right now and very beautiful. It looks like it might be in the iris family but it is not something I am familiar with. So if you are reading this and recognize the plant, please let me know what it is.

Mystery flower.

Mystery flower is Gladiolus imbricatus, originally from southeastern Europe/Turkey. It has been growing unattended for at least fifty years. Thanks to Garry Fletcher for the identification.

Floyd continues to visit Great Race. He spends extra time in the water, suspended and fairly weightless, understandably more comfortable, considering his great bulk.

Eighteen elephant seals continue to haul out on Great Race and their moults are at different stages, depending on start time. The animals that arrived early appear to have completed their moult except for the regrowth of vibrissae. Animals that arrived recently, like Floyd and the female, 5086 are just starting the process.

Some gulls are already looking broody and sitting like they are practicing for incubation. Mating pairs can be seen throughout the colony.

My family continues to visit. Chores and maintenance included a lot of regular tasks, some monthly jobs and a few extraordinary repairs. The fire-pump ran for several hours today adding to the seawater in the cistern.

This plant was introduced to Race Rocks by Assistant keepers in the 1980s. From a small flower bed near the assistant’s house It has spread over much of the Great Race Rock Island. Since it is a member of the Crassulacea family, it uses the crassulacean acid metabolism (CAM) method for fixation of

Carbon Dioxide for photosynthesis. Since it can fix Carbon into a chemical when stomata are open only when its cool at night, it is very resistant to drought, and can survive with very little soil.

The mat of green is a monoculture of Sedum anglicum, English Stonecrop growing on the concrete surface of the large gound-level cistern.

It is of course not the only introduced species on Race Rocks but since it is not grazed by anything, it is rapidly replacing the sparse growth of native species such as thrift  and grasses in the rock crevices.

Introduced Ornamentals

Light North wind this morning. Strong Westerlies this afternoon. Rain with periods of sun.

1 tour boat

This morning was the first time this Spring that there have been a few California Sea lions resting on the end of the jetty.

With Spring mostly here, many of the introduced ornamental plants are flowering. This isn’t a complete plant inventory, just a selection of plants that I noticed on my photo walk. The terrestrial plants at Race Rocks are dominated by introduced and invasive species. This is something that occurs at most light stations. There is a long history of trying to make the light stations look “like home”; Which is usually done by introducing hardy ornamental plants that can survive (although only a few thrive) on remote, salt and wind blasted light stations.

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.

Pam and Dennis Visit the Ecological Reserve

 ‘Garry took Pam and Dennis Birley out to the Island today. Pam does the monthly photo diary from camera 5 from her home iin Leicester England .

Pam took the following images when she was out on the island and on the boat. See her gallery here.
