Bushwalk at Lake Parramatta
Our next walk will be at Lake Parramatta. We will be walking on the West side of the Lake which is more rugged. There is a large variety of plants growing on the sandstone here. However, the recent dry spell means we probably won't see many flowers. The challenge will be to identify plants without them. Walkers will still be rewarded with beautiful views over the lake. We may have time to walk to the dam wall with views down the Hunts Creek valley. We will meet at the car park accessed from North Rocks Road. If the car park is full, there should be space to park in Whitbread Place on the opposite side of North Rocks Road. Please wear closed shoes and a hat. Bring water.

The speaker will be James Indsto, one of our own members. Many members will remember James’ fascinating talk to us last year about the mimicry used by Diuris Orchids to encourage pollination. James will talk this time about his experiences as a forensic botanist. He has always had an interest in science and horticulture and started out by training in horticulture. A BSc. in biology led to a role in plant virology research and then in cancer genetics. This led to a position with NSW Police as a forensic botanist, where he has undertaken major crime case work. In his talk James will explore some of the techniques used to present evidence such as analysing leaf fragments, wood, pollen and Cannabis. James says “Simple microscopy techniques can be very useful. Quality photography is a big advantage. Forensic botanists usually have limited time and resources for specimen preparation, so simple is good. My forte is specialized photography techniques so these will be featured. An important principle in expert evidence presentation is the idea that the expert needs to demonstrate their ability to do the work. Gone are the days when a respected person such as the family doctor might give an opinion on almost anything and be believed. So showing the actual evidence is important. Most forensic botanists spend most of their time on drug botany. I am in the process of writing up a project on Cannabis microscopic features photographed using photomacro technique with image stacking. This has been a reason to develop skills in this area.” The meeting will conclude with an end of year celebratory afternoon tea. Visitors are welcome.
