Urban Forest Strategy - Glossary of terms

Terms used in our Urban Forest Strategy are listed below.
202020Vision: A national campaign across Australia to increase urban green space by 20% by the year 2020.
Biodiversity: The variety of all life forms on earth: the different plants, animals and micro-organisms and the ecosystems in which they are a part.
Biomass: The biological material of a living plant. Capital Works Program: A program of works conducted by Council which renews, upgrades or creates new infrastructure to support the delivery of services to the Geelong community.
Carbon sequestration: The ability of trees to absorb carbon dioxide from the atmosphere through their leaves.
CBD: Central Business District.
Ecological resilience: The amount of disturbance an ecosystem could withstand without permanently changing or damaging it.
Ecosystem: A community of organisms interacting with each other in their environment.
Evapotranspiration: The movement of water from the landscape to the atmosphere through vegetative matter by the process of evaporation and transpiration.
Future Proofing Geelong: A partnership of organisations that supports the Geelong region towards a low carbon future.
G21: Geelong Regional Alliance of government, business and community organisations working together to improve the lives of people across five municipalities: Surf Coast, Colac Otway, Golden Plains, Greater Geelong and Queenscliff.
Greening the West: An initiative that takes a regional approach to urban greening in order to enhance liveability for communities in the western suburbs of Melbourne.
Greenway: A project run by Council to revegetate the Ted Wilson bike trail that runs the length of the Geelong Ring Road. Supported by Barwon Water, The Federal Government’s Department of Environment, the People and Parks Foundation and the Lions Club. Council is committed to planting over 80,000 trees along the Greenway by 2018.
I-Tree Eco: A model built by the United States Forestry Service that analyses certain tree parameters in conjunction with air quality measures to determine an environmental value of a tree. The value includes air pollution, carbon sequestration and storage, energy saving benefits, stormwater flow reductions and a structural value, allocating an overall figure of worth on a population of urban trees.
Integrated water cycle management: A holistic approach to water that promotes the sustainable use of all available water resources in ways that best deliver multiple community objectives.
Liveability: An assessment of what a place is like to live in, taking into account environmental quality, crime and safety, education and health provision, access to shops and services, recreational facilities and cultural activities.
Microclimatic moderation: The ability of trees to cool the ambient temperature through shading and evapotranspiration for the benefit of pedestrians.
One Planet Principles: A set of ten principles adopted by Council within the Environment Management Strategy 2013-2017 that help the community progress towards living and working sustainably.
Remnant Vegetation: The patches of native trees, shrubs and grasses that remain in the landscape.
SEIFA: Socio-Economic Index for Areas which categorises census parcels based on socio-economic advantage or disadvantage.
Stormwater interception: The halt or reduced flows of stormwater into the drainage system for re-use.
Urban density: The number of people inhabiting a given urbanised area.
Urban Heat Island Effect: When urban areas are warmer than surrounding rural areas due to heat retention in hard surfaces. This build-up of heat is re-radiated at night time, increasing air temperatures which can have serious human health consequences particularly during heatwaves. The UHI effect can be mitigated by a range of factors. The most cost effective and efficient mitigation tool is an increase in tree canopy cover.
Water sensitive urban design: The integration of the water cycle into urban planning and design by recognising all water streams in the urban environment as a potential resource, for example: rainwater, stormwater, grey water and blackwater. WSUD is often used to describe the infrastructure built to capture and reuse stormwater
