URBAN ECOLOGY
•
•
•
•
•
•
Define “watershed”
Define pervious and impervious
Urban heat island
Biodiversity
Habitat
Human experience
• By the year 2030, 60% of the world’s
populations will live in cities.
• King County grew 44% from 1970 2000, from 1.2 to 1.7 million residents.
WATERSHED
A watershed is the area of land where all of
the water that is under it or drains off of it
goes into the same place.
URBAN WATERSHED
• Pervious: permeable
• Impervious: impermeable
VEGETATION
•
•
•
•
•
Shading
Evaporative cooling
Rain capture and filtration
Habitat
Recreation
• Impacts multiple cycles: water, carbon,
nutrient
• Resource consumption
URBAN HEAT ISLAND
• City warmer than its surroundings
• Modification of land surface by
development and waste heat from
energy use: heat absorption and lack of
evaporative cooling
BIODIVERSITY
• diversity among and within plant and
animal species in an environment
HABITAT
• Fragmented, isolated and degraded
• Simplified and homogenous species
composition
• Modified ecosystem process
• Example: decomposition, fire, wind
DEMOCRATIC ACCESS
SUSTAINABILITY
• to support, hold, or bear up from below;
• to keep up or keep going, as an action
or process
GREEN INFRASTRUCTURE
• An interconnected network of green
space that conserves natural ecosystem
values and functions, and provides
associated benefits to human
populations
• To create a bold
integrated Open Space
Plan with
implementation
strategies for Seattle’s
next 100 years, which
will enhance the health
and well-being of both
cultural and natural
environments. This
vision of a regenerative
green infrastructure will
strive to create a
healthy, beautiful
Seattle while
maximizing our
economic, social, and
ecological sustainability.
