Wind and Snow Damage

On April 29th 2010 in Calgary, Alberta there was a significant winter storm that caused many issues including tree failures.

Along with all the snow that has fallen in Calgary over the past few days, there has been a significant amount of wind. The damage to the utility poles around Alberta is a testament to the storms strength. We saw a few damaged trees as a result. A few trees with weak branch or stem attachments had broken like the one pictured below.

Falling Trees

We also saw some trees that were actually uprooting at the base. This is a scary situation when the trees is leaning towards a building or other obstacle. That’s exactly what we ran in to in the South East of Calgary. These trees appeared to have problems growing roots outside of the initial planting hole. When combined with the extremely wet conditions and wind, they started to blow over.

We took a short video with our digital camera before we had to cut this tree down as it looked like it might fall any time. It was leaning right over a house. The video below shows the base of the tree, as the wind blows the water is sucked down under the root ball and as the gust dies down, the water is forced back to the surface.
