Hahndorf Part 1

Kudos to Canberra Connect. Kim from Urban Trees rang me seven days after I called to discuss tree removal in Haig Park. She advised that Pinus Radiata has the status of a weed, but due to the heritage nature of the planting they would replant the same species as removed, in more or less the same positions. (Also, apparently pines are very hard to prune.) There is therefore not a specific plan for the work or the layout of Haig Park generally. An arborist is contracted to perform the job.

No tree survey exists for the location, but there is a Trees Database, probably for the wider region. Unfortunately, it is not accessible to the public, except under Freedom of Information laws or a friendly purposeful request.

Here are some pieces of the park I removed to practise drawing.

Ink painting of male strobilus and other features from tree in Hahndorf, South Australia.


Video of pollen being released from the same tree. It is probably microsphoryll containing pollen. I don't know if this applies to the conifer in question, but the female strobilus containing the megaspore or mother cell does appear in the first spring at the end of branches where male strobili are manifest. Their meeting begets megasporophyll and so on.



This would explain the shape of the tree I sat under with four spiders for some time. Of course there were undoubtedly more than four spiders present, but these particular four made my personal accquaintance.

Is not the magnifying glass the greatest instrument of scientific discovery, considering it can be bought for as little as the price of two cans of baked beans?

Conifers are a good subject for ink painting and I got my hands on a roll of rice paper in Adelaide for further practice.
