Developing sense of place in the Mawson Lakes Campus using a science lens

 
1. Using your (Un) Common Sense(s) to connect to your place

Exploring through smell

The first thoughts that came to mind after smelling the surrounding area of our tree were words such as, damp, moist, wet, fresh and green. Rainfall from the previous day most likely explains why my senses picked up on these characteristics. 

As I got closer to the tree I noticed that the sensation of dampness and humidity increased slightly and there was also a musky scent in the air. I could also smell freshly cut grass, which is most likely explained by the adjacent fairway of the Mawson Lakes Golf Course.


Exploring through touch

As I ran my hand over the trunk and thicker branches of the tree I noticed it was quite smooth, almost like very fine sandpaper. In some areas the older bark had begun to flake away and the texture of these pieces were crumbly and crunchy. The older bark that had flaked off was crunchy under my feet at the base of the tree. There were strange ‘knobbly’ bits on the thicker branches where it looked as though some branches had been pruned. Where the larger branches bent upwards, the surface of the tree was wrinkled like old skin. 


Leaves

Ground Leaves

The leaves that I observed and collected from the leaf litter at the base of tree all differed in shape, size and colour. The differentiation in the leaves suggests that some may be from a different species of tree and have been blown towards our tree by the wind.

Touch and sight: The older, brown leaves felt much more delicate than the yellow and ‘greener’ leaves. The tips of the longer leaves appeared to be decaying and were grey in colour. The texture on the surface of these leaves resembled very fine sandpaper. These leaves also crumbled and snapped under very little pressure.

The yellow and green leaves found on the ground were much more durable than the brown leaves. They could be bent over on themselves without breaking. The ‘greener’ the leaves were, the more durable they seemed. The yellow ones were still durable but not as firm as the green leaves. The difference in colour most likely suggests the age of the leaves and how long they have been on the ground. 

Branch Leaves

 
Touch and sight: The leaves on the branches all seemed to be a similar length. Some were more rounded and others were pointy. They all felt leathery to touch, aside from the lumps and bumps, most likely caused by feeding insects. 

The insect bites on the leaves were most prevalent on the outside edges of the leaves. The reason for this is most likely because this area of the leaf would be thinner and less fleshy, thus easier for a small insect to bite through.

Bark


 
Touch and Sight: The bark on the tree ranges in colour from a light grey to a light chocolate brown. The older, chocolate brown bark appears to flake away in long strips exposing the lighter grey colour underneath.


 
There was an assortment of textures, gradients, shapes and sizes in the bark collected at the base of the tree. The colours ranged from dark brown/almost black, lighter browns and reds. There was a link between the darker colours and the ‘curliness’ and ‘delicateness’ of certain pieces which suggests the darker pieces were older

 
As you can see from this photograph, the bark towards the base of the tree turns a reddish brown colour before it flakes off. We can assume that the pieces resembling this colour are much ‘younger’ than the darker pieces found in the litter.

Effects on Neighbours


It appears as though our tree has a negative effect on some of the surrounding neighbours. Because of its height, the canopy blocks out much needed sunlight for smaller neighbours and they are unable to thrive in the conditions. There are stumps surrounding the base of tree where some neighbours have suffered fatalities, and by the looks of things, this tree in the above photograph may suffer the same fate in the near future.
