Barn Swallow Habitat

Barn Swallow Habitat

1. What work is happening on site?

Three (3) Barn Swallow Nesting Structures are being installed as part of Trillium Park.  The structures are considered as new habitat and are required due to potential disruption to existing barn swallow habitat on the Pod and Cinesphere complex. Disruptions to existing habitat may occur due to the repair works being undertaken to the Pod and Cinesphere complex.  To install the new nesting structures, footings will be installed below grade that secure the main support posts and nesting structures. Fencing, matching the existing cedar/rope, will be installed around the perimeter of the area along the pathway. An interpretive sign mounted on a wooden frame, also requiring a small footing, will be installed to explain the function and benefit of the nesting structures.  During the work, tree protection fencing, erosion and sediment controls will be installed on a temporary basis.

2. Why is this work required?

The work is being completed to create new nesting habitat for barn swallows, which are a Species at Risk in Ontario receiving habitat protection under the Endangered Species Act (ESA). Creation of nesting habitat for barn swallows is a legal requirement (under the ESA/O. Reg 830/21) to compensate for barn swallow nests that are anticipated to be impacted (damaged/removed/excluded) by the repair work to the Pod and Cinesphere complex. New nesting habitat must be completed prior to any repair works starting on the Pods and Cinesphere complex that may impact existing nesting.

3. How long the work will construction of the nesting structures take?

Approximately 2 to 3 weeks. On site work is expected to start March 21, 2022 and expected to be completed in the first week of April, 2022.

4. Will this work impact public access?

Public access will be temporarily (for ~2 weeks) restricted from one secondary (non-primary) pathway using pylons.

5. Will this work impact the landscaping of Trillium Park?

No tree or shrub removal is required. Tree protection fencing will be installed around all trees near the work limits. Areas of ground cover being impacted has been minimized and is limited to areas directly adjacent to the structure installations). Any impacted areas will be re-planted with similar perennial species, if required (as recommended by the original landscape architects of Trillium Park).

6. How long will these structures be installed for?

The structures are required to remain in place for a minimum of three years.

7. How will you know that the structures are being used by barn swallows?

New habitat will be required to be monitored annually by qualified experts (biologists) for at least three years. Through this monitoring process, evidence of use by barn swallows will be assessed and recorded.

8. What kind of mitigation measures are in place to deter vandalism and protect the structures?

A rope fence in keeping with the original design of Trillium Park will be installed around the perimeter. Natural vegetation and planting are also being used as a deterrent. An interpretive sign asks people to kindly not disturb the birds and explains the intended purpose of the structures.
