The Adaptations and Response of Organisms to the Abiotic factor of Rainfall

Canada geese are dependant on the availability of fresh water at Race Rocks. During the winter, the higher level rock pools are refreshed by rainfall. There is no other natural source of water on the island. By the time their eggs hatch in June, most of the pools have dried up, so they have to take their young off the island and over to the mainland. They may make it past the eagles….(Photo by PB)

The availability of water for vegetation on Race Rocks has major implications for the species of plants which can survive on the island. Not only do they have to survive dessication from salt spray, but abundant water in the winter months and almost a total lack of water from June to September. One of the best grasses to tolerate these conditions is Fescue. Here you can see it growing on the natural rock outcrops on the island.

Branded sealion, desalinating water with sunshine, Good bye Race Rocks

They all came to wave goodbye

Eco-guardian cross over day. I arrived here barely over a bout of sciatica. I wasn’t sure if I should cancel my week but thought I could do all the absolutely necessary tasks, even if I had to crawl to take the water samples! As it turned out I was able to clean the solar panels, top up the batteries, collect enough wood to keep the house warm, clean the house, start a thorough cleaning of the fuel shed, scrub the walkways in the rain and do the necessary tasks. It was difficult though not to carry out the tasks I enjoy, like carrying a bucket of water to clean the lamp room or splitting wood.

I love the challenge at Race Rocks of living with a small environmental foot print. The abundant life here, that I deeply care about, inspires me to decrease my fuel consumption. This visit I did not need  to use the house furnace and heated my hot water on the woodstove. I even used this method of heating water for “Thai” showers. Cleaning the solar panels when they have dew on them and the walkways in the rain helps too. If I didn’t love my coffee first thing in the morning I could probably cook on the woodstove too. Maybe next time!

Observations

The 2 moulting elephant seals are still by the jetty. One is looking very good, all open sores are healed over. The other one is still panting away and shivering. I sent a video and have heard back from Candice at marine mammal rescue at the Vancouver Aquarium  and she would like to be kept informed if his status changes (rescue@vanaqua.org). Still no luck getting his tag #. I should note that I have not seen any infant seals this visit. I have scanned the rocks. My usual visit is in late April and there are often nursing pups.

The branded sealion 1191 below has been reported and we await back information.

Finally the two immature bald eagles are on the island at the same time and I believe they are the same age, less than a year. Do you agree?

I am currently running the desalinator on sunshine! Amazing.

This is the screen we live by on Race Rocks. It tells how how much energy we are using and how much we are producing. Right now the sun is producing 4.88 kw and we are consuming 3.8 kilowatts while running the desalinator.

Weather

The day started out with thick cloud cover. The sun broke through around 1400 hrs. The wind is currently 13 knot SE. Scattered clouds.
