A brief description of the IPM program:

Humber's North Campus Arboretum Landscape Management plan is dependent on season and weather. The plan includes the following practices:
• Use of dormant oil sprays and selective pruning to remove or limit overwintering pests and diseases.
• Identify and monitor known pests and diseases using phenology checklists, landscape reports from OMAFRA and visual inspection previous infestations
• Identify beneficial insects, reptiles and amphibians and encourage habitat through planting of native and host plant species, timing of plant cleanup (leaving leaf and plant litter as nesting and overwintering sites)
• Physical removal of pests through manual and mechanical means to maintain an acceptable threshold of damage.
• Remove of plants that cannot be maintained at an acceptable level and replanting with more resistant types.
• Use of insecticidal soaps and other sanctioned plant health additions and strategies such as neem oil, aerated compost tea, correct amounts of organic fertilizers and adequate watering.

A brief description of the institution's approach to plant stewardship:

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 guide's Native Species Planting List.
Humber's Arboretum has specific areas that have been designated as native plant materials only. This does not call for the removal of all exotic species only of invasive ones.
• Plants are sourced from nurseries that can identify their seed source and falls within the seed zones closest to our location –zones 37, 34, 33, 32.
• Areas surrounding the ponds are planted with native herbaceous and woody species specific to habitat.
• Other areas of the site –select native species for use if suitable.

A brief description of the institution's approach to landscape materials management and waste minimization:

Humber College has a composting program that uses most of its landscaping waste as mulch, and the rest is composted. Grass clippings, leaves, and small plant trimmings are composted on site within the Arboretum grounds at North campus. Grounds maintenance staff use a mulching mower to clip grass. Other mulch material such as tree limbs and branches are chipped and used on garden beds.
