Austin “a continuous network of [green] corridors and spaces, planned and managed to sustain healthy ecosystem functions” + to generate human benefits
NECESSARY: connectivity multiple functions ecosystem services GREEN INFRASTRUCTURE- narrow definitions
Greening gray infrastructure: “by greening our “gray infrastructure” (buildings, roads, bridges, pipelines, etc.)— effec vely so ening the lines between the human-made and natural environments— we can create urban systems that serve human needs and protect and restore environmental quality.”
Steve Nicholas, City of Sea le Office of Sustainability www.djc.com/news/en/11135643 Crown Street, Vancouver GREEN INFRASTRUCTURE- narrow definitions
Stormwater management: “Green infrastructure [strategies] infiltrate, evapotranspire, capture and reuse rainwater...to maintain or restore natural hydrologies.”
“green infrastructure prac ces include rain gardens, porous pavements, green roofs, infiltra on planters, tree [plan ng] and rainwater harves ng”

URBAN FORESTRY: Urban forests are trees, forests, greenspace and related abio c, bio c and cultural components in areas extending from the urban core to the urban-rural fringe.
Urban forests must be strategically managed and incorporated as green infrastructure into land use planning both spa ally and temporally to ensure their ability to provide a sustainable supply of ecological and socio- economic services, and support healthy, sustainable communi es.
Tree Canada: Canadian Urban Forest Strategy 2019-2024 Green infrastructure is defined as the natural vegeta ve systems and green technologies that collec vely provide society with a mul tude of economic, environmental, and social benefits and include: Urban forests, stormwater systems, green roofs, parks and open spaces, urban agriculture, natural heritage Urban forests are cri cal components of urban infrastructure that exist on private and public lands: • Public trees and vegeta on include street trees, those in parks, as well as municipally managed forested areas and conserva on areas.
• Private trees and vegeta on include those in private front and backyards, around apartment buildings, in parking lots, and on commercial and industrial lots.

Charles E Li le - Greenways for America 1995 greenways-linear open spaces that preserve and restore nature in ci es, suburbs and rural areas.
Li le also coined them “networks of green” 1990 GREENWAY
GREENWAYS— corridors of various widths liked together in a network including ecologically significant corridors, recreational corridors, historical or cultural corridors (Fabos L&UP Greenways Special Issue, Vol. 33 1995)
Diagram of Surrey’s Green Infrastructure Network URBAN GREENWAY
City of Vancouver GREENWAYS 2018 Greenways in Vancouver are linear public corridors for pedestrians and cyclists that connect parks, nature reserves, cultural features, historic sites, neighbourhoods and retail areas. Vancouver Greenways can be waterfront promenades, urban walks, environmental demonstra on trails, heritage walks and nature trails. Greenways expand opportuni es for urban recrea on, provide alternate ways to move through the city, and enhance the experience of nature, community and city life. h ps://vancouver.ca/streets-transporta on/greenways-for- walking-and-cycling.aspx NATURAL AREA HABITAT AREA
What is a natural area?
What is a habitat area?
Are they one in the same? NATURAL AREA HABITAT AREA
City of Vancouver Biodiversity Strategy 2016 Natural areas are forests, wetlands, streams, and other ecosystems that are composed primarily of native plants and animals.
For example, older forests in Stanley Park, wetlands in Jericho Beach Park, the Still Creek corridor, and Trout Lake are considered natural areas.
Naturalness was estimated for each polygon on a scale of 1 to 5 with 1 being maintained vegetation, and 5 being undisturbed, natural vegetation. NATURAL AREA HABITAT AREA Vancouver definitions: HABITAT: An area or type of environment in which a species of plant or animal lives such as a woodpecker in a forested habitat. From Vanplay Ch 5
HABITAT AREAS: Patches of landscape that have habitat values for one or more species.
Erickson “Hubs, sites and links” page 18 NATURAL AREA HABITAT AREA Vancouver definitions: HABITAT: An area or type of environment in which a species of plant or animal lives such as a woodpecker in a forested habitat. From Vanplay Ch 5
HABITAT AREAS: Patches of landscape that have habitat values for one or more species.
Hubs are defined as natural areas greater than 10 ha in size comprised of vegetation of naturalness 3 or greater. Erickson “Hubs, sites and links” page 18 Sites are smaller areas of natural or semi- natural vegetation (naturalness 3 or greater) between 0.1 and 10 ha in size. TYPES (CATEGORIZATIONS)
TYPES (CATEGORIZATIONS)
WHY CATEGORIZE? • Define the structure and functions of urban systems like parks systems • Understand relationships of parts of systems • Prioritize
TODAY: FUNCTIONS SCALE NATURALNESS JURISDICTION
NOTE: Project 1 is all about categorizing. This is an Urban nature by cityprotocol.org introduction. FUNCTIONAL CATEGORIZATIONS
Amenity?? OR Recreation and respite?
Functional?? (all are functions) Maybe: functional + amenity are 1 category- human purposes

Shades of green -choose words carefully and be clear about intended meaning
Green networks: All of a city’s pubic open spaces which provide multiple ecosystem services and are ideally interconnected
No single effective categorization - use multiple categorizations to understand different aspects
Scale matters + primary functions of green spaces change with scale (and jurisdiction) PROJECT 1
PROJECT 1
What are the most important greenspaces at the different scales?
What are different ways of categorizing greenspaces and how does this differ at these three scales?
Do/how do the most important func ons of greenspaces differ across the scales (and therefore types of greenspace)? PROJECT 1
