In a continuing effort to remove invasive plant species on our Sheridan campuses, in the coming week the Office for Sustainability will be removing the tall grass (Phragmites australis), that is situated in the river at Trafalgar, between the SCAET building and Marquee pub. The removal process begins this Thursday, April 5th.
Although the Phragmites australis on campus is beautiful to observe, as an invasive species they tend to have many negative effects on the biodiversity of our local environment.
The Government of Ontario has provided a list of these negative effects and some include:
- The crowding out of native plants
- Generally known as poor habitats and food supplies for wildlife
- It grows faster than many native species and thus consumes higher amounts of water and nutrients, leaving very little for native vegetation.
This particular invasive species prefers to grow, and thrives in areas with standing water. They also release toxins from its roots into the soil, making it nearly impossible for local species to survive long-term.
There are key factors when identifying the invasive Phragmites australis. Not to be confused with the local Native Phragmites of Ontario, you can tell it is of an invasive nature by density, colour and height.
If the stalks are tan and extremely dense, it is invasive. A couple of other telltale signs are the height of its stalks and colour of its leaves. Fully-grown they can reach heights of 15ft. The colour of the invasive leaf is of a blue-green tint. Compared to the native species, which is much shorter, with a green stalk and yellow-green tinted leaves.
The removal process begins next Thursday, April 5th. Please look for and follow the signage that will be placed in the work area. The removal will take place by the river at the Trafalgar campus, between the SCAET and Marquee pub buildings.
Your patience and understanding throughout this process is greatly appreciated.
