Race Rocks Ecological Reserve #97 Warden’s Report ,

We departed Pedder Bay on Second Nature with Greg who was taking Joan Rosenburgh out for an Ecoguardian exchange.  Before leaving we noted a new perch location on the new docks at Pearson College .

 

On arrival, a nice greeting from the group of Northern and Californian sealions near the docks

I took photos of all the adult elephant elephant seals still at the reserve :

 

 

There have been many improvements that the Ecoguardians and the college staff have done since the last time i was here.One important improvement has been the installation of a new toilet system which seems to be a big improvement over past models.

I was interested in relocating the spot where a new geo-positioning system was installed last year, since I had been unable to locate it one time when i was out there. So these pictures are for future reference for relocation. When scientists come out to recheck , the results from satellite triangulation at this spot can indicate the amount of tectonic plate movement .

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.

Pelicans and Owls and Misery!

It is mid-November isn’t it? So why did 9 pelicans just fly by the window? And yesterday a Snowy Owl showed up for the night. Is there something going on with the weather or climate that is encouraging this? We live in interesting times… and speaking of interesting, Misery returned the day before yesterday. I noticed him down at the boat-ramp and we had a little chat! I felt he recognized me! Later he lumbered up onto the lawn looking very fat and sleek, well-prepared for his 2-3 month fast ahead while he stakes his territory, fights off potential challengers, and “courts” any females that might around.

Lastly the other day I heard a commotion in the kitchen and upon investigation I discovered a bird in the oven vent. I removed the cowling and this European Starling appeared and flew around the house for a while. Starlings are a species introduced from Europe (Sturnus vulgaris)in 1890. About 60 were released into New York’s Central Park in an effort to introduce every bird species mentioned in the works of William Shakespeare. By 1945 they were appearing in the Pacific Northwest. About 200 million are thought to exist in North America presently.

European Starling – Good owl food?

 

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)

Sturnus vulgaris: European Starlng-The Race Rocks Taxonomy

Starlings are of course, one of the worst introduced bird species in North America. Fortunately they are not that common at Race Rocks, as there are no nesting locations for them.

This starling was trapped in a vent.

Garden Escapes and Invasive Species of Great Race Rocks Island.

towerstockThroughout the year, on the main island of Great Race Rocks, a changing array of introduced garden flowers range over the landscape of the island. This island had been used by the British Colonial Navy and then by the Canadian Coast Guard since the 1860’s . During that time, many light keepers and their assistants had brought ashore soil and had planted gardens for their own provisioning. Along with the soil came many introduced species, and over the years, those species of plants that have been tolerant of the salt spray and the extreme drought of the summer months have survived. A further selective force was the “trimming and mowing” of the grass and the rock knolls on the island. Fire was always a hazard and as a result every attempt was made to prevent the build up of organic materials. In 1997 when Lester Pearson College started managing the environment on the island, a decision was made to attempt to restore the grassed area to a more natural environment by leaving it in its natural state. The introduced flowers are not cultivated, if they survived the conditions, they are allowed to flourish. Those that are unpalatable to Canada geese grazing now have an advantage. The unique thing about these perennials is that they often remain flowering throughout the winter since the air temperature, moderated by the surrounding waters keeps it the above freezing.

Sedum sp.: possibly Sedum album see also below This was introduced beside the assistant keepers house in the mid 1980s and has since spread over most of the rock-exposed parts of the island, partially because of increased pressure of Canada goose grazing on other plants Calendula sp.: Native to the area from Macaronesia east through the Mediterranean region to Iran. Also shown beside the paths below where it self-seeds each year. Cheiranthus allionii: Perennial wall flower, native to the Canary islands. This plant will flower throughout the year.In mild winters it does not stop blooming. Cheiranthus allionii .–wallflowers near the residence with the tower in the background

Passer domesticus: House Sparrow- The Race Rocks Taxonomy

 

Domain Eukarya
Kingdom Animalia
Phylum Chordata
Sub-Phylum Vertebrata
Class Aves
Order Passerifomes
Family Passeridae

Genus Passer
Species domesticus

Common Name: House Sparrow,  Passer domesticus

One of the worst introduced European species in North America because of their habit of preying on other nests in the area they are frequenting , 

Given that house sparrows are so common everywhere else, it is surprizing that they are rarely seen on Race Rocks. 

Normally this species can be quite damaging to other nesting birds but there are few other small birds that nest here other than the occasional barn swallow.

This bird was the subject of the Classic Paper by Bumpus on Limiting Factors
