Observable Characteristics
pH values between 1-3 are considered what?
Acidic
Recreation and adventure.
Using the outdoor environment for enjoyment and to engage in positive risk taking behaviours, is called what?
Dryland soil salinity
What is a result of land clearing, cropping and irrigation practices?
What does DELWP stand for?
Department of Environment, Land, Water and Planning (DELWP) and Parks Victoria
Gariwerd
What is the Indigenous name for the Grampians?
Stagnant, algae present and smells bad.
What are some indicators of poor water quality?
Name one important reason for maintaining biodiversity.
1.All species have a right to exist (humans respect non-human species)
2.Species reduction reduces the richness of a human experience
3.Many species in the future may be found to have new properties in terms of food, medicine, and renewable and biological resources
Why does the water table rise (and therefore salts)?
When deep-rooted trees are cleared for farming and crops are planted.
Trust for Nature
Name a non-for-profit organisation that works to protect native plants and wildlife in cooperation with private landowners.
Name 3 pests (other than Sallow wattle) in the Grampians N.P.
foxes, rabbits, deer, goats, feral cats, Sallow Wattle, South African Weed Orchid
10m transit line
How do you assess the amount of biodiversity in an outdoor environment?
Economic value.
Tourism, exportation, mining and agriculture are all examples of using outdoor environments for what?
Over fertilising and wetland drainage for irrigation.
What causes soil contamination?
What is a conservation covenant?
A management agreement placed on a property’s title to ensure native flora and fauna on the property are protected forever
Conservation covenants are one of the most effective ways to protect flora and fauna on private land
Why is Sallow wattle a pest?
It crowds other native flora species such as Tea Tree.
What indicates healthy/fertile soil?
Dark in colour (moist), different materials (more nutrients), thick growth of flora, no erosion and worms or insects living in it.
What provides society with an understanding of the complexities of outdoor environments?
Scientific research
Why are blackberries considered an environmental threat?
The plant reduces native wildlife habitat, limits access to water sources, displaces native plants and provides habitat and food for pest species
Why is Australia's biodiversity declining?
±Habitat loss, degradation and fragmentation
±Invasive species
±Unsustainable use and management of natural resources
±Changes to the aquatic environment and water flows
±Changing fire regimes
±Climate Change
What is a management strategy for feral/wild goats in the Grampians?
Judas goat. Buying a goat from a local farm, tracking the goat and releasing it into the National Park. The Judas goat will want to find other goats so the rangers can then manage the feral/wild goats (muster, trap or shoot)
Less than 4.8 and greater than 9.2
What range of pH levels can be harmful to aquatic life?
Derived from the natural environment.
Where do the ingredients in contemporary medicines come from?
Explain three potential impacts of climate change.
±Increase in intensity of droughts and floods
±Reduction in fish stocks
±Increased risk of bushfires
±Loss of coral reefs
±Species extinction of species with low adaptability or mobility
±Changes in ecosystems
Explain 2 conservation and 2 recreation duties of park rangers
Conservation:
Eradicate and control pest animals and weeds, maintain historic sites, identify and protect threatened species
Recreation:
Create and maintain trails, maintain facilities, education services, respond to emergency situations
Explain two measures our rock climbing guide, Hugh, told us about when taking clients climbing, to ensure the outdoor environment is not negatively impacted.
Rubbish out
No chalk
No screws for climb anchors
No engraving initials on rocks
