Visit to Chester Spring Marsh

This week, we visited Chester Spring Marsh, which is about a 20 minute walk from Riverdale Park.  It has been decided that our team would visit the site a few times this season as it hasn't had a regular stewardship team working there since 2004.  Consequently, it's very dense and was left to its own device, so there is a lot of maintenance work needed.

After going through a wooded path, we emerge on a beach right on the Don river.

We didn't waste any time and started pulling an incredible amount of invasives. 

We had 3 piles like this one of all the stuff we pulled including garlic mustard, stinging nettle, burdock and dame's rocket.

I also noticed quite a bit of Japanese knotweed, another highly invasive species in the valley because of its rapid growth and height.  The Global Invasive Species Database has listed it as one of the World's 100 Worst Invasive Alien Species. According to an article in Wikipedia about Japanese Knotweed "The invasive root system and strong growth can damage foundations, buildings, flood defences, roads, paving, retaining walls and architectural sites." There is also an interesting video posted a few years ago on Don Watcher's blog.

Manitoba Maple. 

We managed to clear quite a large patch of these seedlings which have had a field day on this site in the last few years.

My co-leader Christine.  She is not the one who damaged that tree, none of our tools would have such a devastating effect on a tree.  It was of course the work of beavers.  Amazingly, the tree is still alive.

Lots of burdock and it's getting pretty big everywhere on the site.

I took this picture which shows a tree that's almost completely flattened in the ground, I don't recall ever seeing something like that.
