Cars kill 300 year old tree

500 block of Victoria St, centred on large tree

Another piece of Oak Bay’s urban forest was lost this week. A large Garry Oak in the 500 block of Victoria Avenue was removed because it was diseased and thus was a potential risk to falling over. Given it was around 300 years old, age does tend to catch up to even the best of us. But this tree did not really die of old age. It was felled by root rot. What caused the root rot? Well, the story in the Oak Bay News lays it all out:

A younger Garry oak might have been able to fend off the disease, but the Victoria Avenue tree’s age and damage done to it when the street was widened in the 1970s weakened the root system left the oak vulnerable to disease. (emphasis added)

Thats right. It was killed because the road needed to be wider. What can clearly be seen from the photo to the right above is that the road and sidewalk ran almost right against the trunk. As evidenced by this case, driving on a trees roots damages them via soil compaction. But how far out do they extend? A good rule of thumb is the that the roots extend at least as far as the branches or crown does, often further in urban areas. (The Southern Nevada Water Authority has a good graphic and explanation).

Of course, Oak Bay is not the only offender. Parking lots are great places to see just how bad it can get for these poor trees. Case in point; the parking lot at Camosun’s Lansdowne Campus as seen to the left. Formerly a Garry Oak meadow, the trees remain but the grass is now concrete.

The Garry Oak ecosystem is amongst the most endangered in the world and its centerpiece species, the Garry Oak, the only native oak west of Manitoba.

Coincidentally, a lady from the Garry Oak Ecosystem Recovery Team was at Oak Bay council on Monday night looking for some funding to help print their book, The Garry Oak Gardener’s Handbook (PDF link).Thankfully council was able to give them about $200 for 40 copies. She also had a few on hand, so I picked one up and having read through, I highly recommend it. I am looking forward to the newer, larger, edition coming out later this year.

TC’s special on Rebuilding Canada

The Times Colonist (and presumably the whole Canwest newspaper chain) has a special entitled “Rebuilding Canada”. That they are running such a piece now isn’t really a surprise, given the massive number of stories talking about an “infrastructure stimulus“. What really gets me is the focus on rebuilding and adding new roads. One of the choicer quotes comes from a story titled “The scramble to make our highways safe“:

Elsewhere, Edmonton has a $260-million interchange project to unclog a bottleneck on a ring road.

You can’t build your way out of congestion. This is the hard lesson Boston is discovering, after their giant “Big Dig” project. Aside from all the well documented problems with quality of the construction, what they have found is that the faster traffic flow in the core has simply pushed bottlenecks outwards. The traditional answer to this would be to “fix” the new bottlenecks with more roads, which would just be perpetuating the cycle of endless construction, which is how we ended up here in the first place. We need to build less roads and reduce the number we already have, not be adding more.

But where is the talk about using transit to solve some of these bottlenecks? The problem is that planners and governments fail to look at mobility holistically. Essentially, we need to be planning how to move people more efficiently, not cars. Some organizations get it, such as Washington States Department of Transportation and their page on bottlenecks and chokepoints. Others, well, just don’t.

Of course, roads are not the only piece of infrastructure that is crumbling. Recreational facilities and housing, garbage disposal, sewers and public transit are all covered as well. Sewers are an interesting one. Apparently the City of Victoria has some of the oldest sewer pipes in Canada, at almost 100 years old. All well and good, but where is the discussion of using bioswales (CRD on bioswales) and green roofs (Ecogeeks has a good photo-filled FAQ on green roofs) to reduce runoff into our sewers? As the CRD plans to charge municipalities based on flow, reducing runoff means less tax dollars wasted.

Overall, I am deeply disappointed with this whole series. It is typical tired journalism. Given the recent cuts in the Canwest newsrooms, I am not surprised they are failing to produce good, innovative stories. I guess that leaves it up to the poor bloggers to tell the story.

Silly pedestrian, sidewalks are for cars!

Today while walking back from Camosun, I saw no less than three trucks parked on the sidewalk. Frustrating.

This looks like a contractors truck, given the construction in the house right at this location.

This Cadillac Escalade is owned by somebody who lives here. I see this car here nearly everyday, usually parked on the curb to some degree on another.

Tomorrow is my first final of three. I hope to get back into the blogging spirit as we roll closer to Christmas.
