Fair test - repeat measurements, randoms sample that is representative]]> 2022-10-10 03:58:21 UTC https://padlet.com/lmgraham/43r0lf51ive2l69e/wish/2332977889 https://padlet.com/lmgraham/43r0lf51ive2l69e/wish/2332978392 How is the population of Native trees affected by the distribution and density of introduced species? 

We will observe a square of the forest and count the amount of Camphor Laural and eucalyptus trees. Then see how they have affected each other's growth, Density, and population.

In our study we have come to the conclusion that many native trees such as Okra and Sandpaper Fig are being suppressed by introduced species such as the Camphor Laurel. Many native trees are growing in very small and are maturing at a very small size not at their potential. This is most likely from the little amount of dappled light that that native trees are receiving because of the tall expansive camphor laurel trees. Also, the large Camphor laurel trees may be soaking up nutrients that is beneficial for native trees. 


Results: (Taken from a 5x5m Quadrant)

Camphor Laurel (Big): 5
Camphor Laurel (Small): 12

Sandpaper Fig (Big): 0
Sandpaper Fig (Small): 21

Ocra (Big): 3
Ocra (Small): 8

Palm (Big): 0
Palm (Small): 2

We are going to look and record the amount of fungi found and take pictures to see the different types of species. 
- Camera/phone to take pictures of different fungi.
- Book to record amounts of fungi..

During the investigation we found that there were two main types of fungi found near the creek, Agaricus (3 found) and Auricularia (13 found). Although the role of these fungis were not orginally found through the investigation, we have since learnt that the Agaricus fungi plays the important role of degradating leaf and needle litter in temperate forests, whereas Auricularia fungi helps to absorb exess water.

 - collect water from multiple points along the creek
 - determine quality (pH) and microscopic life
 - compare with town and tank water


Results:

Through testing the pH levels in the creek we confirmed that the water had a neutral pH level. In the first three locations of the creek (downstream) the pH measured at 7.50, and upstream the pH measured at 7.25. Compared to distilled water the pH levels show that the concentration of Hydrogen ions compared to distilled water is 0.

Take multiple samples in different places of the creek

After taking 10 samples our results were:
Sample 1: 8
Sample 2: 8
Sample 3: 8
Sample 4: 8
Sample 5: 7
Sample 6: 8
Sample 7: 8
Sample 8: 6
Sample 9: 8
Sample 10: 8
Average: 7.7
Animals that can live in this ph level are:
Eels, Shrimp, Frogs

- Research common species 
- Document and identify the species
- Create a map documenting the plant species within a 5 meter radius.
 Species found 
- okra
- Christmas bush
- Ferns
- Lamandra 
- Fig
- moss 
- camphor laurel 
The plant species diversity changes depending on the distance from the creek. Using a quadrat, we measured the plant species located within a one meter radius at different distances from the creek. Starting on the creek bank, one meter from the water, plants such as the fig and ferns thrived. However plant species like Lomandra and moss are still evident. Two meters from the water, ferns prosper with around 15 within the quadrat, while still being surrounded by the two figs, moss,  and 1 Lomandra, while showing new species such as the Christmas bush and camphol oral. While advancing further away from the water and into the forest, species such as okra becomes evident. While Lomandra, Christmas bush, moss and camphor laurel, while the fig is not apparent. Finally, 5 meters away from the creek, there is no longer Lomandra, fig or moss, but more ferns, camphor laurel, okra and Christmas bush. Overall, the species diversity changes depending on the distance from the water, however we have measured it in a smaller 1 by 1 quadrat, and to get accurate data, would need to measure the diversity along the entire coes creek and forest.

What diversity of plants are found in the forest?
- Record the different species of plants in the area
- Where are they located(distance from creek, elevation)
- 
The species we found around and near the bank include Camphalaurel, ferns and Lomandra 
A bit further in the forest we found palm trees, ferns, camphalaurel, Lomandra, ocra, sand paper figs and Berry Bushes
Deeper in the forest there was palm trees, camphalaurel,

The most common species of plants found in the forest was camphalaurel and palm trees which were found near the water bank and further in the forest.

What is the species diversity of the forest?

Results:
As the group did not systematically count the number of organisms that were present, it is difficult to make a measure of species diversity.  The species that were counted were
1 eel
5 mushrooms
1 crayfish
1 fish
A wild monkey
