Task one: The Gully Section of the Ridge track.
Aim: To see the different species of plants spread over a distance.
Hypothesis: That across the distance, that we would find different types of plant species.
Materials: - Belt transect
- measuring tape
Methods: 1. Measure out the distance that you will cover
2. Draw up a belt transect between 0 – 80m
3. In 10m intervals, place the species found at their correct measurement of finding on the belt transect.
Results:
vegetation key:
| Symbols | Vegetation name |
Trees | AC | Angophora Costata (Sydney Redgum) |
| C | Coach Wood |
| SP | Sydney Peppermint |
Shrubs | BA | Blueberry Ash |
| SW | Sweet Pittospurum |
| PR | Pittospurum Revolutem |
| SU | Sunshine Wattle |
| BS | Banksia Serrata |
| HP | Hairpin Banksia |
| D | Drumstick |
| B | Burrawang |
| FG | Forest grass free |
| MD | Mountain Devil |
Ground Cover | MF | Maidenhair fern |
Other | | Sandstone boulder |
Discussion: From this we see that every metre there was either the same or different species of plants, 14 different species were found over the 80m that were cover. There were also a few sandstone boulders.
Conclusion: From this it is evident that there is a wide range of plant species across the large area due to the abiotic factors.
Task two: Measurement of Abiotic Factors at site A and B.

Anemometer |
Light meter |
Compass |
Clinometers |
Aim: To compare the abiotic factors at two different sites.
Hypothesis: That there will be a difference in abiotic factors in the two different sites.
Materials:
Abiotic factor | Instrument | Ridge top results | Gully result |
Air temperature | Thermometer | 24 C | 24 C |
Humidity | Hydrometer | 54% | 53% |
Soil PH | PH test kit | 3.5 (acidic) | 5.5...
