Urban forests must be strategically managed and incorporated as green infrastructure into land use planning both spaally and temporally to ensure their ability to provide a sustainable supply of ecological and socio- economic services, and support healthy, sustainable communiQes. Tree Canada: Canadian Urban Forest Strategy 2019-2024 Green infrastructure is defined as the natural vegetave systems and green technologies that collecvely provide society with a multude 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 crical components of urban infrastructure that exist on private and public lands: • Public trees and vegetaon include street trees, those in parks, as well as municipally managed forested areas and conservaon areas. • Private trees and vegetaon include those in private front and backyards, around apartment buildings, in parking lots, and on commercial and industrial lots. hps://greeninfrastructureontario.org/urban-forests/ GREENWAY Charles E Lile - Greenways for America 1995 greenways-linear open spaces that preserve and restore nature in cies, suburbs and rural areas. Lile 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 demonstraon trails, heritage walks and nature trails. Greenways expand opportunies for urban recreaon, provide alternate ways to move through the city, and enhance the experience of nature, community and city life. hps://vancouver.ca/streets-transportaon/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.
