Impacts Flashcards
Conservation
Is the preservation, protection, management or restoration of the natural environment.
Conservation positive impacts
Preservation of sensitive vegetation.
Protection of areas of significant value (creation of State and National
Parks).
Reduce erosion - due to creation of walkways, paths
Rehabilitation of areas - due to track closures
Reintroduction of species into areas they originally inhabited.
Conservation negative impacts
Vegetation modification - due to controlled fire burning.
Land clearing due to conservation infrastructure - tracks, walkways,
toilets, buildings.
Permanent structures - viewing platforms, information buildings,
barriers/fences.
Disruption of habitats.
Commercial activities
Commercial activities result in profit or gain - utilising the environment.
Recreational activities
Is any activity for enjoyment amusement of pleasure.
Can be undertaken as nature based or adventure based.
Recreational activities positive impacts
Inspiration & Creativity - Artists, musicians and writers have
all interacted with our outdoor environments and used them
for inspiration.
Aesthetic value - the emotional responses we get from our
interactions with the outdoors. How we feel from our
connections with environments.
Education - occur through school or group trips. Also include
the teachings of OES at Padua College. Learn about the
environment and ways that we can protect and conserve it.
Urbanisation
Urbanisation refers to the development of towns and cities, and the increasing number of individuals that live in urban areas.
Ecological footprint
the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
Integrated farming
An approach to farming combining tradition methods with modern technology to achieve higher levels of productivity without increasing the environmental impact.
Direct impacts
Direct impacts are those caused by the action and occur at the same time and place, usually observable.
Indirect impacts
Indirect or deferred impacts are those that are caused by the action, but not immediately. They happen before an event, or later in time but are still reasonably foreseeable.
Urbanisation impacts on waterways
- disruption of ecosystems
- increased turbidity
- rising salt levels
- loss of stream side vegetation
- erosion of creeks and watercourses
- increased stormwater runoff
- water pollution
Urbanisation impacts on land
- decrease in biodiversity levels
- lack of dead wood and forest litter
- introduction of weeds
- loss of topsoil
- increased water absorption into soil
-loss of old hollow trees - habitat loss
