Signs of Fall

Fall looks as if it’s here to stay as temperatures are set to lower sharply next week. The first dip below zero of the season is forecast for October 30 which is slightly earlier than Toronto’s average of November 1-10.

Here are some recent images of the park as it eases into the approaching winter.

Today in Raymore Park

A large Norway Maple by the parking lot is coming closer to the end of its life. The tree provides much needed shade but its days appear to be numbered as more rotten branches are found. It is the last of several large maples that once lined (and shaded) the parking lot.

Signs of Fall: tree planting

In the last 20 years, thanks to old age and disease, there has been a steady reduction in the number of mature trees in Raymore Park. Quite a number of these trees are invasive non-natives such as Siberian elm and Norway maple. While many hundreds of native saplings have been mass planted in the wild areas, no mature boulevard trees have been planted to line the pathway.

On Monday September 23rd, 43 trees were planted along the entrance and pathway as far down as the weir. This will make a big difference in years to come as the path is quite exposed in both winter and summer. I only have one slight quibble with the choice of trees; quite a number are black walnut and the park has no shortage of those already. There are quite a few water-loving weeping willows where the path comes near the river and some maples too.

A couple of Toronto Forestry workers were inspecting the trees yesterday and they told me that for the most part the trees were planted to the correct specifications by the contractor. A few have been planted too high and will need to  be adjusted and some look a little straggly, but for the most part it has been a successful planting.

This is the perfect time of year to plant trees as the ground is still warm and autumn rains will ensure lots of moisture for roots to grow.

Count 'em - it's 43!

Count ’em – 43 new trees!

Textures, invaders and regeneration

Trees come and go in the park whether they are felled by old age, ice or by the latest foreign invader, new ones rise up and take their place. Many of the new ones are foreign invaders themselves.

Norway Maples have become ubiquitous in Eastern Canada – even to the point of having their leaf on our currency. They have been in Canada for hundreds of years and are able to grow more quickly and produce leaf earlier in the season than native trees. In addition, their shallow roots and dense shade have a smothering effect on native tree seedlings. As for Siberian / Chinese Elm, I can honestly say I must have killed thousands of saplings in their attempts to establish a beachhead in my back yard.

This old Norway Maple provides wonderful summer shade to cars in the Raymore parking lot but its age is showing and its hollowing interior has become home to more than a few squirrels. It drops the occasional limb now and then and will soon become a victim of old age. Unfortunately its replacement (if any) will take many years to provide the same cover. Hopefully the replacement will be from a native species.

Across the path from the parking lot attempts have been made to mass plant native trees and shrubs with varying degrees of success. Part of the problem is that the saplings (thanks to the availability of student labour) are planted at the hottest time of year. Last summer, a substantial batch of saplings was delivered to the planting site and left in plastic bags for a day in hot sunshine before being carefully planted. Needless to say, thanks to bad planning, only a tiny fraction survived, wasting a whole lot of time, effort and money.
