Hectares
Figures required to calculate the total area of managed grounds:
| Area (double-counting is not allowed) | |
| Area managed organically, without the use of inorganic fertilizers and chemical pesticides, fungicides and herbicides | 1.34 Hectares |
| Area managed in accordance with an Integrated Pest Management (IPM) program that uses selected chemicals only when needed | 0 Hectares |
| Area managed using conventional, chemical-based landscape management practices | 0 Hectares |
| Total area of managed grounds | 1.34 Hectares |
If the total area of managed grounds is less than the total campus area, provide:
The footprint of buildings and impervious surfaces were not included in the area of managed grounds, as well as lands that are not maintained by Douglas College such as boulevards (that are maintained by the New Westminster and Coquitlam in the respective campuses).
As Douglas College is an urban campus, the overall area of managed grounds is low compared with the overall campus area. Douglas College has two different categories of landscape management practices carried out by different contracting firms:
- one is for the green roofs on campus (Architek), totalling 0.1161288 hectares
- the other is for general grounds landscaping (Lawnsplus) totalling 1.2225 hectares

If reporting an organic program, provide:
Douglas College has two different types of landscape management practices carried out by different contracting firms: one is for the green roofs on campus (Architek), and another is for general grounds landscaping (Lawnsplus). Descriptions of each practice can be found below:
Landscaping practices for Green Roofs (Architek):
As a regular practice for green roofs Architek uses organic, soluble forms of carbon, nitrogen, phosphorus and magnesium. Architek also use soluble seaweed concentrate for trace minerals. Once a year it may be necessary to use compost teas and extracts that are biologically proven to contain adequate amounts of beneficial microorganisms. Please see supporting documentation for more information on these amendments that are used by Architek for green roof care.
NOTE: 0.1161288 ha is the combined size of green roofs on Douglas College campuses.
Grounds landscaping (Lawnsplus)
Lanwsplus manage weeds on campus by hand weeding and hoeing rather than using herbicides, use aeration practices, use lime for moss control and fertilizer for lawns, and employ frequent cutting of lawns without the use of herbicides.

Optional Fields
Landscaping practices for Green Roofs (Architek):
The majority of the plant material on the green roofs is sedum species, there is a mix of native and non-native sedum in the plantings that we have used.

A brief description of the institution's approach to hydrology and water use:
Landscaping practices for Green Roofs (Architek):
Sedums are very drought tolerant plants. We take a very conservative approach to water by only irrigating once per week or less.
Other grounds landscaping (Lawnsplus)
Bark mulch is used on campus for weed control and to cover exposed roots and help with water retention during summer drought.

A brief description of the institution's approach to energy-efficient landscape design:
Landscaping practices for Green Roofs (Architek):
Douglas College uses very drought tolerant plants and strive to use as little water as possible. All weeding is done by hand and without the use of fertilizers or gas/electric powered equipment.
Other grounds landscaping (Lawnsplus)
All weeding is done by hand and without the use of fertilizers or gas/electric powered equipment.
