Stage 6 Biology - Module 3 and 4 | Ecosystem Dynamics - forest ecosystems
Georges River EEC
Program overview
Bring ecological science to life in this focused Stage 6 fieldwork program, where students investigate how abiotic factors shape the distribution, behaviour, and interactions of living organisms within a forest ecosystem. This program will focus on sandstone geology vegetation, hollow bearing trees, koalas and sulphur-crested cockatoos; their niche and interactions within the ecosystem.
Students will engage in a series of investigations designed to generate valid, reliable data to answer key inquiry questions about ecosystem structure and the influence of environmental variables. Throughout the day, students will identify potential risks, plan safe procedures, and apply authentic scientific fieldwork techniques to build confidence, competency, and curiosity as developing ecologists.
Fieldwork activities include:
- measuring abiotic factors such as light intensity, temperature, wind speed, relative humidity, soil moisture, soil depth, soil colour, and soil texture
- conducting a belt transect survey of Sydney red gum (Angophora) and Grey gum (Eucalyptus) populations, recording saplings, juveniles, mature non-hollow-bearing, and mature hollow-bearing trees
- observing bushland fauna, with a focus on koalas and sulphur-crested cockatoos and their ecological niches
- predicting potential niche overlap with other species and considering the consequences for koala and cockatoo populations and those of competing species.
Across this immersive experience, students will analyse relationships between abiotic and biotic components, use key standardised sampling techniques, observe species interactions, and develop a deeper understanding of how environmental factors influence ecosystem dynamics.
Recommended for up to four classes per day.

Content
Population Dynamics
Inquiry question: What effect can one species have on the other species in a community?
Students:
●investigate and determine relationships between biotic and abiotic factors in an ecosystem, including: (ACSBL019)
– the impact of abiotic factors
– the impact of biotic factors, including predation, competition and symbiotic relationships
– the ecological niches occupied by species
– predicting consequences for populations in ecosystems due to predation, competition, symbiosis and disease
– measuring populations of organisms using sampling techniques
