Yr 12 Ecosystems at risk

Littoral rainforest of Minnamurra Spit

Year 12 Geography

Ecosystems at Risk

Location

Minnamurra Spit

Program overview

Students examine the Littoral Rainforest of Minnamurra Spit as a case study of an ecosystem to be compared with a second, different ecosystem at risk. Students study the unique characteristics of Minnamurra Spit, including the:

  • spatial patterns and dimensions: location, altitude, latitude, size, shape and continuity
  • biophysical interactions including:
    • the dynamics of weather and climate
    • geomorphic and hydrologic processes such as earth movements, weathering, erosion, transport and deposition, soil formation
    • biogeographical processes: invasion, succession, modification, resilience
    • adjustments in response to natural stress
    • the nature and rate of change which affects ecosystem functioning
    • human impacts (both positive and negative)
    • traditional and contemporary management practices.   

Inquiry and focus questions

  • What are the reasons for the location of the Minnamurra Spit and associated Littoral Rainforest?
  • What action is appropriate for managing the Killalea State Park sustainably?
  • What will the Littoral Rainforests of Minnamurra Spit be like in the future?

Key syllabus outcomes

Geography Yr 12

Ecosystems at Risk

Students:

  • use geographical skills and tools
  • identify geographical methods applicable to, and useful in, the workplace

Students learn about:

  • ecosystems and their management
  • biophysical interactions which lead to diverse ecosystems and their functioning
  • vulnerability and resilience of ecosystems – impacts due to natural stress – impacts due to human induced modifications to energy flows, nutrient cycling, and relationships between biophysical components
  • the importance of ecosystem management and protection – maintenance of genetic diversity – utility values – intrinsic values – heritage values – need to allow natural change to proceed
  • evaluation of traditional and contemporary management strategies
