Principles of Ecological Landscaping• Solves or mitigates current
environmental problems.
• Does not require excessive
resources for long term
maintenance.
• Helps maintain or create a
healthy ecosystem(i.e. contributes to biological
diversity)
• Respects local conditions such
as topography, hydrology and
soil conditions.
• Accomplishes all of the above,
while also adding beauty and
functional space for humans.

Principles of Sustainability
• Development which meets the needs of the present
without compromising the ability of future generations
to meet their own needs (Brundtland
1987)
• Near constancy of natural resources
• Equilibrium relationship between human activities and
the physical environment
• Intergenerational fairness

Applications of Ecological Landscaping• Green Roofs, Meadows, Xeriscapes, Urban Forests, Rain Gardens

GREEN ROOFS Quick Facts
• Modern building materials allow greening of almost all
roofs.
• They are not “new.”
Green roofs are common practice
in Norway, Sweden, Germany, and Switzerland and have
been for decades.
• Habitat for pollinators, songbirds, plant biodiversity.
• Reduced lifecycle costs for buildings.
• Valuable source of green space in dense urban or
agricultural settings.
• TIP:
Don’t think of them as “green roofs.”
Consider
them yet another place to design for gardens and spaces
for humans.

MEADOWS and PERENNIAL GARDENS Quick Facts
• Source of biodiversity and pollinator habitat.
• Higher up front costs but reduced life cycle costs.
• High quality native meadows establishment
distinct from "just stop mowing“
commonly seen in
naturalization areas.
• True naturalization involves removing exotic sod,
and actively planting wildflowers and native grasses.
• Meadows in dense urban areas require more
planting design to remain publicly acceptable.

XERISCAPES Quick Facts
• Uses engineered growing medium designed for low weed pressure
and excellent drainage.
• Allows for demonstration of responsible water use of
municipalities.
• Establishment requires care and attention to preparation of site,
but is as lowest in annual input there after.
• Designed for zero irrigation with long‐lived plants.

URBAN FORESTRY Quick Facts
• Associated with increased property values and greater community
care.
• Engineered soil is absolutely necessary in dense hard‐scapes. Trees
live short lives in downtown cores.
• Tree selection of paramount importance
• Long term human care and use should be integrated.

Challenges of Ecological Landscaping
• Misperceptions that naturalization is simply not mowing the grass.
• Up front costs.
• Different from traditional aesthetic, although these can be mostly mitigated.
• Lack of standards, knowledge of practices within landscape industries.
• Shortage of products needed for these projects in Canada.
ECOLOGICAL LANDSCAPING For Communities small to LARGE
How to Mitigate Challenges
• Demonstration projects in city parks and streetscapes.
• Corporate sponsors willing to pioneer techniques or fund municipal projects; education regarding lifecycle costs.
• Education regarding lifecycle costs, water use for traditional gardens.
• Research standards and practices from other countries.
