Stage 6
Students investigate the characteristics of this wetland ecosystem through collecting first hand data on water quality, completion of vegetation transects, and conducting aquatic macroinvertebrate and bird surveys.
Students observe human induced modifications to the ecosystem and strategies to maintain ecosystem functioning and actions for sustainability. Students discuss the dynamics of ecosystem functioning in this wetland ecosystem.
Inquiry questions
- Describes the characteristics of the ecosystem and the dynamics of ecosystem functioning including, resilience, vulnerability and ecological disturbance.
- Describe the human induced modifications to the ecosystem.
- Assess the effectiveness of ecosystem management in terms of maintaining ecosystem functioning and actions for sustainability.
The program includes:
Introduction
Fieldwork including:
- Investigation into the characteristics of the ecosystem including: water and air temperature, humidity, wind speed and direction, water depth, pH, turbidity, dissolved oxygen and salinity, using various equipment and data loggers.
- Construction of a flow chart to represent the interaction of factors and systems that influence the characteristics of the wetland ecosystem.
- Investigation of the nature of biodiversity in the ecosystem through: - the sampling of aquatic macro invertebrates to calculate the species diversity and abundance in 2 different wetland ponds. - Completion of a vegetation transect. -Completion of a bird survey.
- Discussion of economic, political and sociocultural factors that influence the management of the wetlands at the Hunter Wetlands Centre.
- Walk around wetlands observing the human induced modifications and ecosystem management for sustainability.
- Discussion of the vulnerability and resilience of this ecosystem.
