The living ecosystem in Delbrook creeks needs protection

Keegan Casidy, who has written on this site before on environmental issues and our creeks today offers us a fascinating video of salmon fry in Mission (Thain Creek). Mission Creek is an important tributary to Mosquito Creek.

Keegan writes, “Did you know that Coho fry spend a year in their Creek/Stream before leaving to the Ocean?

“This extended rearing phase is often the limiting factor for the species success. In the Summer months the fry have to deal with hot temperatures and low flows, and during the Winter they rely on deep slow moving pools for refuge.

“Mosquito Creek like many urban streams have their challenges.
One of which is they generally have large storm drain networks that are fed by our roads. Mosquito has seen mass fish kill offs in the past from negligent residents. Low flows during Summer and Winter months make this a very challenging time for the life under the water.

“Also, many urban streams have lost complexity created by large fallen trees and the deeper pools that come with it. These deeper pools are few and far between. It is likely almost every fish within several hundred meters has come to seek refuge in this one pool, making it critical to the species success on this watershed. The challenge here is there is literally so few of these refuges that you can count them on 1 hand.

“Another challenge is that Mosquito Creek has a large off leash dog area and with it these refuge pools have become dog swimming pools. There are 4 areas on Mosquito that were created specifically to help the Salmon. 1) The channel south of the skateboard bowl (Griffin Channel) 2) The channel below HWY 1 which runs parallel to Fell Ave (Fell Channel) 3) The two Alcoves that hold deep still water, there’s one just south east of the trailhead coming down off Fell Ave hill (West Alcove) 4) The other just a few steps up from the closed trail sign from the access on 19th to the East trail (East Alcove). Although Fell Channel is highlighted at every entrance as a “No Dog” zone, many trail users ignore these signs. There is very little water that enters this channel regardless of the time of year, and very little summer and wintering refuge, so dog pressure is magnified.

“East Alcove has significant dog pressure, especially during Summer months when dog activity kicks up silt and sediment to suffocate the fry.”

Editors Note: One of the uses the Delbrook Community Association has suggested for the Delbrook Lands site would include environmental education on issues such as this.

Arson fires hit south Delbrook area

If you find this article interesting, please use the buttons at the end of the article to share it with your neighbours on social media.

BC’s fire season is coming to an end and not a moment too soon for Delbrook area residents.

Friday evening, September 15th, three fires were apparently started in yards and parks in the south Delbrook area. One fire was started in the soccer field area and two on private property. Fortunately, there were no injuries and no houses were affected. A passing videographer captured some of the action and posted it to his YouTube channel at his Canadian Treasure Hunter site. The video is below.

Subsequent discussion with police and firefighters found the cause of the fires was arson and not a thrown cigarette butt.

As the video shows, one tree was candling or torching and sparks could have spread to trees and homes in other areas including Mission Creek. One fire fighter said the situation could have gotten out of control.

It is hard to imagine in this year’s BC fire season how anyone could have been so stupid as to start fires. Let’s hope North Shore RCMP find the people responsible. If you have any knowledge of this please contact the police.

Delbrook project needs to consider environmental issues

If you find this article interesting, please use the buttons at the end of the article to share it with your neighbours on social media.

The following is a really interesting presentation on environmental issues touching on the Delbrook site from long time Delbrook resident Keegan Casidy

Keegan tried to post this as a comment on an earlier blog post, but due to the mysteries of technology, it didn’t work. Perhaps its just as well. This deserves a posting on its own.

 


Hi DCA,

I was at the council meeting yesterday evening, and I am following up to gather more insight with regards to this post’s comment that “most of the land is to be retained as green space.” In particular, what exactly will be done to protect one of the last wild stock Coho & Steelhead streams left on the North Shore, Mission Creek (aka Thain Creek)?

There was little to no mention with what was going to be done with “most” of this land, being that it is proposed to be “Green Space.”

Furthermore, I find it troubling that following a review of the preliminary report, the only mention of Mission Creek was the following:

“Environmental Impact:

Mission Creek riparian area will be protected and enhanced.”

In my volunteer works with the Federal Government’s Department of Fisheries and Oceans, the Squamish Nation, BCIT River’s Institute and other parties – It is extremely important to consider the ecological, economical, and human health values of this creek.

There is a massive opportunity to engage children and give them the opportunity to witness in their back yard one of nature’s most impressive feats, the returning spawning salmon. Something many of us probably took for granted growing up in such a beautiful area that has seen many changes over the decades.

The District has recognized this creek’s value on occasion, with the $1.4M removal of the culvert under Westview drive in 1999, and again most recently with the replacement of the culvert on Windsor Road.

With such significant investments in the past I would hope to see that the right steps are taken to improve what is literally one of the last pieces of “Green Space” left on this creek.

Additionally, I would like to invite you all to the website I have created to read and see the true value of Mission Creek and it’s importance to not only the Delbrook residents, but to all of the residents on the North Shore.
