WHAT IS THE AIM? The aim of this booklet is to illustrate Adelaide’s lack of native flora in the CBD inparticulary around Adelaide oval . We can analysis this by utilitising government websites we can track the growing numbers of introduced species against natives. We can also use software like cloud compare to better visualise what these number actually look like. This booklet is aimed anyone but in particular people involved within the Adelaide city council, if this information was better known and understood maybe we could start to rectify it.
WHERE? The site is South Australia’s capital. Adelaide is situated on the River Torrens which flows from the Mt Lofty Rangers down the hills and out to the ocean at Henley Beach.
HISTORY Settled in 1836 Adelaide was chosen for its abundance natural resources such as timber and water from the Torrens river. Its didn’t take long for residents to dispatch almost all of the native vegetation along the river. This had disastrous effects causing flooding as well as making the city a rather in hospitable place to live. To fix this issue rather than replanting native species people began planting foreign specimens as can be seen in figure 2.
NATIVE VS INTRODUCED OVER TIME By analysing data obtained from environment.sa.gov.au I was able to track the growth of introduced plants vs native plants over a 140 year period in and around the cbd in particular around the Adelaide oval and Torrens river. This graph shows an inherent push to plant introduced species over native. The most interesting part of this data is that even though we understand now the great importance native plants have on our ecosystem we are planting less now than we were 40 years ago, we have actually began to see a rise in the amount of introduced species. 120

EXPLODED AXONMETRIC DIAGRAM By using cloud compare I was able to segment the area of the cbd I had chosen and break it into different levels. This shows the efforts of people to revegetate the city. Although this is probably the most densely vegetated area in the cbd, with building only taking up a small area.

WHAT DIDN’T WORK In my attempts to create a more comprehensive model I attempted to use blender. This created a very interesting model but it on contained man made structures (buildings, road, etc.) as blender uses Open street maps which relies on users upload information to it I may have been better served choosing a site in a more populated city i.e. Melbourne.

OVERVIEW It was interesting to investigate the flora around the cbd as in previous subjects I have learnt about how early settlers cut down most trees in the area. It was worrying to see the contrast in the numbers between native and introduced species that have been planted since the late 1800s. inparticular the fact that even recently the numbers are still pushing towards introduced species.
NEXT TIME Although nature is something that I am very interested in I feel for this assignment there was an overall lack of data to create an interesting model in cloud compare.
