Does the institution own or manage land that includes or is adjacent to legally protected areas, internationally recognized areas, priority sites for biodiversity, or regions of conservation importance?:
Yes

A brief description of the legally protected areas, internationally recognized areas, priority sites for biodiversity, and/or regions of conservation importance:

The Humber Arboretum is a joint venture of the City of Toronto, Humber College, and the Toronto and Region Conservation Authority. Connected to Humber College’s North Campus, the Humber Arboretum covers approximately 250 acres and combines botanical gardens with large naturalized areas and walking trails.
In 2015, a 7.2 ha portion the Humber Arboretum was named as an Environmentally Significant Area (ESA) by the City of Toronto. The city does not permit development within ESAs and restricts activities to “those which are compatible with the preservation of the natural feature(s).” ESAs can be designated on several different criteria; in the case of the Humber Arboretum, this designation is due to the presence of plant species which are considered vulnerable, rare and/or threatened with the city or the Greater Toronto Area.


Has the institution conducted an assessment to identify endangered and vulnerable species (including migratory species) with habitats on land owned or managed by the institution?:
No

Has the institution conducted an assessment to identify areas of biodiversity importance on land owned or managed by the institution?:
Yes

A brief description of areas of biodiversity importance on land owned or managed by the institution:

The City of Toronto, which is one member of a tri-partnership which owns the Humber Arboretum, hired North-South Environmental Inc., Dougan & Associates, and Beacon Environmental Ltd., to prepare a report on Environmentally Significant Areas (ESAs) in Toronto. A 7.2 ha portion of the Humber Arboretum was surveyed over multiple sessions between April and July, 2008. Field assessments followed provincial protocols. The team also drew on research conducted by the Toronto Region Conservation Authority (TRCA) in the year 2000. These assessments were done to identify flora and fauna species which are considered locally vulnerable, either within the City of Toronto or the Greater Toronto area.

The City of Toronto report considered the Humber Arboretum ESA to be in “good condition.” One potential concern was the possibility of encroachment by invasive plant species. With that in mind, Arboretum staff continue to note any areas of concern and are creating a plan for future control efforts in collaboration with the City of Toronto.
The parking lots at Humber College North Campus were landscaped following the City of Toronto's Design Guidelines for 'Greening' Surface Parking Lots. Among the 200 trees and 1000 shrubs installed, three-quarters were selected from the Native Species Planting List which offer a familiar and varied habitat for local wildlife.
