Leaf Watching: The Comox Valley Top Five
My toddler son is keen to collect fallen leaves, clutching fistfuls in each hand and sorting them by shape and colour. He doesn’t know which trees the leaves belong to yet, but I am happy that he is out noticing things and exploring nature.
Most of the broad-leaved deciduous trees (trees that shed their leaves in the fall) are actually easy to recognize with practice. To start with, here are brief descriptions of the “top five” kinds of leaves that one is likely to see in the Comox Valley this fall.
Bigleaf Maple (Acer macrophyllum)
Bigleaf Maple
The bigleaf maple has the largest maple leaves in all of Canada, and the large yellow and rusty fall leaves provide some of the best fall colours in our area. Bigleaf leaves are deeply five-lobed. The brown V-shaped winged seeds fly down like little helicopters.
Maple trunks and limbs are often covered with luxuriant clumps of moss and ferns. The porous, calcium rich bark encourages plant growth. Douglas maple (Acer glabrum), is the only other common maple species in our area. This is a much smaller, more shrub-like tree that grows to ten metres high. Continue reading »
On the Trail of a Snail
Pacific Sideband Snail
Whatever the time of year, we always find something of interest on our nature walks. A few days ago we found ourselves on the trail of a snail, which crossed right in front of us. It glided slowly but stealthily over twigs and needles, toting a brown spiral shell on its back. When I got home, I pulled out my copy of “Land Snails of British Columbia” by Robert Forsyth, an excellent guide to our provinces’ slugs and snails, to learn more about this quiet but compelling creature.
In evolutionary terms, slugs and snails are very successful, with as many as 35,000 species of land dwelling slugs and snails in the world, and 94 species in BC.
Snails belong to a large group of marine and land-dwelling creatures called molluscs. The word mollusc comes from the Greek word “mollis” meaning soft, in reference to the soft-fleshed body. Continue reading »
A Good Year for Pinks
Pink Salmon Head
We took a stroll down to Puntledge Park in Courtenay the other day, to see the salmon in action. All seemed quiet at first, then with a sudden splash we spotted a salmon, swimming up through the riffles of the stream. The salmon spawn is a beautiful thing, and reminder of the natural cycles of life and death that we are all a part of. Along river’s edge, we found a freshly deceased male pink salmon, and admired the colours and markings of the fish up close. The pink salmon (Oncorhynchus gorbuscha) is the smallest and most abundant of the five species of Pacific salmon. Pinks weigh between 1.0-3.3 kg, and are 45-55 cm long. A key identification feature is the tail, which has tiny scales that have no silver, and distinctively large oval spots. Continue reading »
