Sooke River Cedars

Cedar growing along (or in!) the Sooke River.

The Cheewhat Cedar in Pacific Rim National Park is the largest known tree in Canada. This building sized behemoth lives only about 100 km away, as the eagle flies, from my home. Thankfully I don't need to go that far to visit ancient cedars.

Cedars favour a moist, wet environment making the Sooke River riparian zone prime growing habitat. Only a few kilometres from my house I can access some of my favourite giant, ancient cedars growing where the land and the river meet.


Riparian zones provide rich habitat and have high biodiversity.

Wikipedia describes riparian zones as "important natural biofilters, protecting aquatic environments from excessive sedimentation, polluted surface runoff and erosion. They supply shelter and food for many aquatic animals and shade that is an important part of stream temperature regulation."


There are a trio of trees in this ancient cedar grove on the Sooke River bank.

Cedars are a major part of Vancouver Island riparian ecosystems. This community of plants ensures perfects conditions for spawning and growing salmon. Any damage to the cedars and the riparian zone will result in damage to salmon runs, as has been the case all along BC's coast.


An unhealthy salmon run reflects back on the rivers and damage to the riparian zone results. Every year millions of salmon return to their river birthplaces and provide riparian areas with tons of nutrients. No fish - no nutrients.


Broken top cedars on the river bank show their advanced age.

Some of the local cedars I visit on my bike rides could be up to 800 years old. Or more. I marvel that they still exist, and breathe a sigh of relief each time I go for a visit and see that they are still there.

Then I soak up the history and magic of the riverside groves and of these patient, wise tree beings that have so much to share. They don't call it the "Tree of Life" for nothing.

Soon the salmon will be running along the base of their land dwelling tree friends, continuing the cycle of life for both fish and trees.

Perhaps one day in the distant future one of the Sooke River cedars will be the largest tree in Canada.

Muir Creek: Potential Old Growth Parkland



Just past Sooke along West Coast Road you will find the magnificent Muir Creek watershed. The lower part of the watershed contains one of the most easily accessible chunks of old growth forest left on South Vancouver Island. Here you will find large diameter (up to 3m/9ft), soaring (up to 76m/250ft) Sitka spruce, Douglas-fir, Western red-cedar, and the B.C. Big Tree Registry-listed second largest Pacific yew. If you are in the south island area, Muir Creek is a big tree highlight not to be missed.








Several of the old trees along the creek are large and tall enough to be eligible for inclusion in the provinces registry. This is not surprising - historically some of the largest trees on Vancouver Island came from this valley. So big and tall were the trees of old that sailing ships in the 1800's would anchor off of Muir Creek in search of the best specimens to use as masts.






A monument in Victoria's Beacon Hill Park, touted as the world's tallest free-standing totem pole, began as a tree growing in the Muir Creek valley. It was carved from a 50m (164ft) Western red-cedar that was cut, then floated down the creek before being pulled by tugboat to Victoria. There it was carved by renowned Kwakwaka'wakw artist Mungo Martin and his team. The pole was raised in 1956, and is 38.8m (128ft) tall.




Although the area has been logged since the 1800's - evidence of this can be seen throughout the forest - many old growth trees have survived the decades of extraction. Especially notable for the oldest trees are the lower reaches of the creek and steep hillsides next to it. Modern industrial logging methods such as helicopter logging now make these trees economical to harvest. They are currently within logging territory.



Originally this was part of the T'Souke Nation traditional territory. They used the Muir Creek area for winter dancing and fish processing. The land was taken from them in the E&N Railway land grab of the 1880's. 2 million acres were given to the railway company as compensation for building a rail line.With one stroke of the pen much of the T'Souke's traditional territory became off limits to the very people that had lived there for generations. Politicians of the time said the land held no value to the native groups. Therefore, there was no compensation for this grievous loss.



Since then much of this land has fallen into the hands of industrial logging interests that have used it to generate billions of dollars in revenue. Successive governments have failed to acknowledge the theft of land originally, and continue to fail to ensure it is being cared for by profit-minded multi-national corporations.








The land here also provides access to the ocean, something that is increasingly difficult to find as the south island becomes more developed. There are fossil beds in the seaside cliffs, and at low tide one can walk for hours on the cobble and sand beach. There are occasional large trees to be seen up on the headland as you hike beside the surf.









Rather than being seen for the ecological gem that it is, the Muir Creek area is viewed by some as nothing more than potential profit. Now that Timber West has gone into the real estate business, residential development of these wild lands is possible. Logging activity of second growth in the watershed has increased dramatically and loaded logging trucks are once again rumbling through downtown Sooke. Will the old growth trees be next?





The Muir Creek Protection Society is working to preserve all that Muir Creek has to offer. A park would protect the area for the bears, cougars, jumping slugs, otters, mink, eagles and salmon that currently reside there. 95% of the west coast of Vancouver Island is private land. A park would protect the old growth trees and provide much needed recreational opportunities for local residents and tourists alike.


With the recent purchase of Sandcut Beach and Jordan River property we will be told there is not money available to secure Muir Creek for future generations and the maintenance of biodiversity. That is obviously not true as we easily came up with billions for that big party back in the winter of 2010. TimberWest, CRD, and other officials have discussed the need for parkland between Sooke and Port Renfrew, and Muir Creek has been identified as a prime location.


It would be an awful shame to loose this amazing area. Check it out for yourself - you know what I say, "See Them, Save Them". Stand beneath a 500 year old Sitka spruce and try to maintain perspective. These ancient tree's massive diameter soars skyward with very little taper until the trunks disappear into the canopy of the forest.


The forest here is of an increasingly rare variety, and this is a excellent opportunity to save it from the saw. Encourage the politicians that work for us, and TimberWest that makes a profit exploiting lands of global significance, to save Muir Creek.



Getting There

Muir Creek is 14 km past Sooke on West Coast Road/Highway 14. Once you pass the gravel pit on your left the road dips down to one of the only flat coastal areas along this stretch of the Juan de Fuca. This is the Muir Creek estuary.


Parking is available on the south-west side of the bridge, and access to the big trees is on the north-east side of the bridge. Follow the trail upstream on the east bank of the creek, keeping to your left. The trail will take you to the creek, then continues upstream. Either side of the bridge has trails down to the beach.

Forest Creatures: Snakes and Slugs (Warning: graphic photos)


I was touring one of my favourite big tree haunts recently when I spotted thissssss beautifully patterned forest resident. It reminded me that I was visiting the homes of many creatures that reside in the rain forest, and make up the web of life here. The occasional pile of purple poo from passing black bears was also a reminder that I must be aware of the larger forest residents. Cougars are regular visitors, too. Out here I am prey.

Today the garter snake was the one to make its presence known. Found under the Sooke River Super Cedar of Gargantuan Proportions (I really must streamline this naming thing), this snake was surprisingly fast. When I slowed down, so did the snake. It stretched out before me and sunned a bit in a shaft of light piercing the forest canopy. We stared at each other for a while, his beady black eye to my blue one.




Here is how I envision a garter snake deciding on potential prey:
  • Is it alive?
  • Will it fit in my mouth and down my throat?
  • Can I catch it?
If the prey satisfies these criteria, it is on the menu. I found out on a hike last year, that the garter menu includes the second biggest slug in the world, the Banana Slug (more than 20cm). I didn't think anything ate slugs. Compared to dung beatle fare, slug could be considered a delicacy. After all, slugs are basically snails without shells - large escargot.


The snake did not move while I photographed it attempting to consume this large lunch. How could it? I was simultaneously mesmerized and mortified. I continued on my hike. Both snake and slug were gone when I returned. Note: you can click on any of the photos to get a blown up view of this amazing natural phenomena. Just thought you would like to know...

The garter snake will also eat small birds, leeches, amphibians, small rodents, and other snakes. This snake is very aquatic and in coastal areas fish makes up a large part of their diet. The snake I saw recently was next to the Sooke River, so the tiny salmon I was watching that day were no doubt in trouble when the snake hit the river.

Garters are fast on land and in water. As I watched the snake it slithered off quickly. I had to move fast to follow, hunched over and moving through the understory. About 10 meters away the snake bee-lined (snake-lined?) for a hole at the base of a fallen tree, right under the root ball. Had I discovered a snake den, or "communal hibernacula"?
Garter snakes spend the winter in communal dens, sharing space and warmth through the cold temperatures. This looked like one. I had a sudden urge to stick my hand in. Why? I resisted. One should not harass wildlife. Especially snakes. Do not touch garter snakes unless you want to see their defense mechanism - they will poop on you (it is very smelly). If they feel threatened they could also bite. Best to enjoy them from a distance, like all wildlife.

Here is a group that is trying to improve life for another coastal snake, the sharp-tailed snake, on Salt Spring Island. They remind us that snakes are an important part of our ecosystem and should be treated with respect. The Salt Spring group educates the public on habitat conservation and builds hibernacula for sharp-tailed snakes. You can build a hibernacula in your own yard or garden. How fascinating would that be?

I will be watching the Sooke River Cedar Hibernacula location in the spring when the snakes will be out on warm days to stretch their bodies (adults are 46cm to 1.3m) and warm in the sun. After being bundled in a coil with a hundred friends all winter, they will be ready for mating. Mating involves bundling up in a ball again, this time with many males surrounding a single female. Garter snakes are live-bearing and give birth in July or August. Baby snakes are born fully developed, and litters range from as few as 5 to as many as 80.

Every creature in the forest ecosystem is important, and that includes snakes and slugs. Slugs are the recyclers of the forest and clean up dead and decaying matter and return nutrients to the soil. Snakes keep insect and rodent populations in check. Many forest animals feed on snakes, including raccoons, blue herons, eagles, and owls. If you can respect slugs and snakes, and recognize their important place in the cycle of the forest, surely you can respect everything in the forest. Such respect is sssssorely needed today.
