Old Growth Trees Provide Valuable Habitat

 Pileated woodpeckers have excavated the thick bark of this old growth Douglas fir

Intact large tracts of old growth trees and forests provide irreplaceable habitat for a wide variety of living things. Many can not thrive in any other habitat, so when the trees go, so does a large part of the forest community.


The Pileated woodpecker is one of the largest
woodpeckers, and can be found in
the coastal temperate rainforest




Old Douglas fir like the one shown above can have bark up to 30 or 40 cm thick. This bark is deeply furrowed and provides habitat for feeding, nesting, and roosting animals.


Woodpeckers, like the largest species in the world, the Pileated, access insects in this cork-like bark.









Some bats roost under slabs of bark



Large slabs of bark can also harbour sleeping bats.


Bats have few predators, and human activity causes them the most harm. Some “tree bats”, such as Keen’s Long-eared Myotis, are dependant on old growth forest for roosting.


These bats, like so many other old growth residents, are endangered due to habitat loss.

Spotted owls also depend on large old trees for their habitat. It is estimated that there only 12 Spotted owls left in the wild in all of British Columbia.


The province has started the world's first captive breeding program for the owls, but with no habitat to return the birds to, the Spotted owl's continued survival outside of zoos is unlikely.





We don't know what is at risk when we destroy the primal forest for these forests have never been extensively studied. 

If we did a serious survey of old growth logging we would see that we are losing much more than we are gaining when we cut primal forests. When the big old trees go, so does the entire forest community, in what can only be called ecocide. 

A ransacked community means reduced biodiversity which means a less robust, less productive environment. 

We need an immediate end to industrial clear cut logging in our primal forests not just in BC, but globally. The slugs, and birds, and bats, and insects are depending on us, as are the trees.

Our own survival may depend on the outcome of the fight for maintaining ecological integrity.

No Respect For BC's Big Trees

2 homeowners hired an arborist to illegally cut or damage 35 trees
in Capilano River Park to 'improve' the view from the homes

"The tree which moves some to tears of joy is in the eyes of others only a green thing which stands in their way."

BC's big trees, despite attracting thousands of tourists every year, have a hard time getting respect from some of the people who live under them. Tragically, our government still allows the logging of the last of the big original trees out in what is remaining of our wilderness, while in our cities homeowners are illegally removing park trees to "improve the view".

A tree-cutting incident in a North Vancouver park made the news recently and highlights the attitude that many have in this province. Poet William Blake summed it up long ago when he said, "The tree which moves some to tears of joy is in the eyes of others only a green thing which stands in their way."

Standing in the way of two homeowners living on properties bordering Capilano River Regional Park were 35 trees (in the park) up to 145 years old. The homeowners, in an attempt to improve the view and increase the value of their properties, allegedly found an unscrupulous arborist in the neighbourhood that was willing to take money to remove or damage the park trees.

All three are facing charges of mischief over $5000 dollars, and will have to pay for remediation.

As far as I am concerned, the homeowners reduced the value of their properties. I would be willing to pay extra for the privilege of living in a place with such incredible forest in the back yard. How could you possibly enhance that view?

Whatever they gained in view they lost in slope stability in the area below homes where the trees in question were  hacked down or severely trimmed. Maybe the houses will be at risk in the future when the slope fails, or when the hole in the forest canopy causes a blowdown event and trees begin to topple. Experts also say the illegal work increased the risk of fire.

Why would you spend $2 million dollars to live in forested North Vancouver if you don't like trees?

As audacious as this sounds, it is unfortunately not an isolated event in the old growth forest of Capilano River Park, which is surrounded by urban development. Last year another tree cutting incident in the park was dubbed the "North Vancouver Tree Massacre" by one news outlet. Again, 'improving' the view was the motive.

A little respect would go a long way when it comes to BC's old growth trees and public spaces.

Resting Under Trees

A good place to rest on a hot summer day.



"Rest is not idleness, and to lie sometimes on the grass under trees on a summer's day, listening to the murmur of the water, or watching the clouds float across the sky, is by no means a waste of time."  - J. Lubbock

Drift Logs Important For Beaches

Beaches on the Pacific coast are littered with bleached drift wood

Drift logs are important parts of beaches all along the Pacific coast.

The banner at the top of this blog is a photo that was taken on a beach in nearby Washington state. When the photo was taken the mammoth drift log was newly arrived on the beach and was still dark and hydrated.

After a while on beaches on the coast, drift logs age to a beautiful sun-bleached white-ish grey colour. The picture at the top of this post is of the very same drift log used for my banner, except the log has been desiccated by summertime sunny days.

But drift logs are good for more than having fun looking at them and climbing upon their prone trunks.

Often drift logs have sawn ends, an indication they are escapees from log booms or other logging operations. Regardless of their origin, drift wood acts as an important stabilizer of beaches.

In the winter these logs are tossed like tiny toothpicks by high tides and pounding waves. In the summer they settle into place and trap sand and organic material. This maintains the beach structure and provides habitat for all manner of living things.

In this way, the trees continue to do work even as they slowly decompose back into the environment.

BC Liberal Government Triples Raw Log Exports

BC Liberal Government More Than Tripled Raw Log Exports to Foreign Mills

Media Release, May 7, 2013 
The BC Liberal government more than tripled the amount of unprocessed, raw logs leaving the province to foreign mills during their reign of power, according to recent figures provided by BC’s Ministry of Forests, Lands, and Natural Resource Operations (Min. of FLNRO) to the Ancient Forest Alliance (AFA). 
From 2002 to 2012, over 47 million cubic meters of raw logs were exported from BC to foreign mills in China, the USA, Japan, Korea, and other nations. This contrasts to about 14.8 million cubic meters from 1991 to 2001 under the NDP government. Over the past two years alone, in 2011 and 2012, record levels of raw logs were exported from BC, 13.2 million cubic meters in total. 
“The BC Liberals have decimated the province’s forestry workforce through massive raw log exports, industry deregulation, and unsustainable practices. 30,000 BC forest workers lost their jobs and over 70 mills were shut down under the BC Liberals, yet they've allowed companies to cut at near record levels,” stated Arnold Bercov, national forestry officer of the Pulp, Paper, and Woodworkers of Canada. “Under the BC Liberals, we lost both our forests and our jobs, it’s nuts.”

World's Largest Yellow Cedars Are On Vancouver Island

St. RandAlly, previous champion Yellow cedar

When it comes to the world's top six largest Yellow cedars, Vancouver Island is where it is at. Five of the top six are in British Columbia (the other is in the state of Washington). Of those five, at least three are on Vancouver Island.

The current largest commonly known specimen of Yellow cedar (Chamaecyparis nootkatensis) can be found near the small town of Sayward on the north west part of the island. It is in an area of big trees along Cooper Creek, and its name is Admiral Broeren.

The previous champion Yellow Cedar grew for many centuries close by to where today's champion stands. Shortly before the St. RandAlly recreational site was to open, the 2000 year old giant tree fell to the forest floor.

The tree was named after Randall Dayton and Ally Gibson, the forestry engineers that discovered the record breaker in 1993. It fell in 2004.

This fallen Yellow cedar boasted impressive measurements:
  • Height 61m (200 ft), 
  • Circumference 13.08m (42ft.11in), 
  • Diameter 4.16m (13.7ft), 
  • Crown Spread 16m (52.5ft), and 
  • Stem Volume 175 cubic meters (6,200 cu. ft). 
Note: Champion trees in North America are determined with a point system used by the American Forestry Association that awards 1 point per inch of circumference at breast height, 1 point per foot in height, and 1 point for every 4 feet diameter of the live crown.
Sgt. RandAlly's score in AFA Points was 728.

Admiral Broeren, at 575 points, has more volume (188 cubic meters) than Sgt. RandAlly, but is smaller in height, crown and diameter.

The British Columbia Big Tree Registry lists a Yellow cedar with more AFA points (618) than Admiral Broeren. It is listed as a "recent addition", is not named and no location is recorded. I suspect it is on Vancouver Island somewhere, but at this time I can not confirm that.

The tree is recorded as having the following dimensions which would make it more impressive than Admiral Broeren, and the largest in the world:

  • Height  46.40 m (152 ft) 
  • Circumference 11.59 m (38 ft)
  • Diameter 3.68 m (12 ft), 
  • Crown Spread 12.2 m (40 ft), and 
  • AFA points 618

Yellow Cedar Facts
  • Yellow Cedar grows well in deep moist soils. 
  • They usually grow as single trees, but may also occur  in small groves. 
  • Can be found alongside western red cedar and western hemlock.
  • Their beautiful, rot-resistant wood is highly valued. 
  • Given optimum conditions, they can reach monumental proportions.
  • Many Yellow Cedars are dying in the northern part of their range - global warming has been fingered as the culprit. 
  • Chamaecyparis is derived from the Greek word for the ground cypress, an Old World shrub; nootkatensis refers to Nootka Sound on the west side of Vancouver Island where Yellow cedar was first identified by botanists.

Range of the Yellow cedar

These trees are common in old growth forests on Vancouver Island, but are rarer in the south island and east coast where it is too warm. In the southern part of their range they are found high in the hills where it is cooler, and where snow accumulates in winter.
