RAINFOREST PLANTS of AUSTRALIA: Rockhampton to Victoria

Those of you who are interested in knowing more about the plants in our local area might like to get hold of this new computer key. Written by Gwen Harden, Hugh Nicholson, Bill McDonald, Nan Nicholson, Terry Tame and John Williams, it was launched last month, and is available on a USB from http://rainforests.net.au, or http://www.rainforestpublishing.com.au. The cost, if ordered on the internet, is $80.00. My first thought was that the price is rather high, but it contains so very much more than could ever be fitted into a single book, that it is definitely worth it. It covers all the trees, shrub, climbers mistletoes, and treeferns that fit within the authors' rather broad definition of a rainforest plant. This includes plants of wet environments like Goomburra, Ravensbourne or the Bunya Mountains; dry rainforests such as those in Redwood Park or Highfields; and even the "scrub" plants to the west of Toowoomba. (There are no "sclerophyll" plants - gumtrees or wattles - in it).

"Keying out" plants can be quite difficult if you use a traditional key, but the great thing about this one is that you can enter anything you know about the plant. It begins with a list of all its 1139 plants. Type in one fact - that it has pink fruits of a certain size, for example - and all plants that don't fit this description disappear from the list. Type in the geographical area, and suddenly you find yourself with quite a short list that makes it easy to find your plant. Add a few other facts, such as the length of the leaves, and you may have identified your plant already, and can look at its description and photos. Or if there are still a few to choose from, you can look at the photos of each of the plants left in the list, which might give you the bit of extra help you need to find "your" plant. Because it's a computer key, it has included lots more photos of each plant than books can afford to publish - 1200 of them altogether, with ten or a dozen of every plant, so you get a really good idea of what each plant looks like. Another use for the program is simply to look up any plant that you're curious about, in the list of names. Because you're given a full written description of each plant, an indication of where it's likely to grow, and photos of the whole plant as well as close-ups of the trunk, flowers, fruit, leaves, etc, you can start to feel you really know that plant. As a bonus, if you order it from Hugh and Nan Nicholson's "rainforestpublishing" site you get a free copy of Volume 1 of their rainforest book series. This is a really a fantastic resource, which I feel sure many of our members would like to own.

Outing Report: West Creek, 09 November, 2014

Twenty Field Nats gathered at the rotunda on Creedon Drive at 9.00am, to be joined by a few more late arrivals. Margaret’s purpose for the outing was twofold – for us to contemplate the changes to the creek wrought by 150+ years of European intervention; and to show us what some of West Creeks’s detention basins look like (to help us project what East Creek’s current and controversial developments might morph into, given time). 

Margaret had quotes from Archibald Meston’s evaluations of “The Swamp”, with comments of mullet in these creeks and leptospermums along the banks where the creek lines connected the then different wetlands along the way. Meston, I believe, was only 18 when he first arrived in Drayton, later to work with Aborigines, and eventually to become Queensland’s Protector of Aborigines by the end of the Nineteenth Century. It would seem that, at 18, he was not accurate in his identifications of fish or plants – yet his letters still carry weight as historical records! 

We learned that this section of West Creek, southwards from the rotunda to Stenner Street, was developed in the 1980s to suit Toowoomba City Council’s then priority for an International Gardens theme – specifically here to create a Palm Grove (Egypt) and the canal structures that connect successive detention basins were to be reminiscent of Holland. Nearby, there are separate lines of Queensland Kauris, ficus species, eucalypts, casuar- inas, willows and poplars – giving us a certain sense of identity crisis. 

Northwards from the rotunda we did a short loop walk around the next few basins, here connected by under- ground pipes. These basins are beside and slightly above the present watercourse, which is lined with imported rocks, to slow the flood flow. The ponds had three species of waterlilies, some of which were beginning to clog the ponds. One wonders what happens to this surplus of (regenerative) plant matter when there is a big flush event. For many of us, the feature of the day was the massed display of the “Snow in Summers” (Melaleuca linariifolia) which were just short of their very best, and intermittently lining the major ponds. Most of us turned around at the end of that first loop, where a tree stump had been expertly capped, so making an ideal habitat for a large and active colony of native bees.    

I think that we as Field Nats were most appreciative of the natives on show, and can’t help but wonder what the creek-scape would have looked like if it were exclusively native species. A chance missed for Toowoomba to have showcased Australia’s unique vegetation. This would have been an ideal opportunity for Toowoomba, the second largest city within the Murray-Darling Basin, and in a significant headwater position within this basin, to have set an example of environmental responsibility. 

While not oppressively hot, it was a very warm morning as we ambled around West Creek. Morning-tea at 10.40am was late for us Nats, but proved leisurely, and gradually lingered towards midday, when we all took an early mark and dismissed for the day. Jean and I walked this area last November and were blown away by the “Snow in Summers”, so I settled upon this for our November 2014, outing. While on our W.A. trip, I became anxious that I may not have time to pull together my part preparations for West Creek if we arrived back too late in October. My thanks to Margaret for taking up this theme on short notice and coordinating our day.
