ARTICLES Climate Change confuses Flowering Trees By George Pinniger A long time has passed since I was in Kindy! Things were much simpler then; we had lots of rules that we were taught over and over again. Every day we stood to sing “God Save the Queen” while saluting the Australian flag. We celebrated everyone’s birthday, usually with cake, and also had quite a number of “special days”, including Wattle Day and Arbor Day, not actual true holidays that we stayed at home for, but were deemed special by the teachers, so most of us went along with that. I recall the little song we were all taught to sing around the middle of August to celebrate Wattle Day at the end of winter: The bush was grey a week today – Olive-green, and brown and grey. But now the spring has come this way with blossoms for the wattle. It seems to be a fairy tree – it dances to a melody, and sings a little song to me – the graceful, swaying wattle. Not far from where I live there’s a fairly small but beautiful patch of wetland I like to visit. Actually, all too soon the M-6 Motorway is very likely to make it disappear in the name of “Progress”, but I hope not because Bayside Council keeps it as tidy as possible, and great numbers of waterbirds are always there, fairly secure from predatory cats because they can rest or nest on a few small islands in the lake. It’s peaceful and beautiful. The Council discovered that small turtles (terrapins) also live in the waters, and made a small floating island for them as well. There’s a bridge crossing the water about halfway between its northern and southern extremities, where many people bring children to toss bread to the hundreds of ducks and other waterfowl that inhabit this spot. 25th June: This is usually the first wattle to bloom; there ar tiny yellow points on many branches, but none are identifiable as blossoms. The three wattles I will focus upon: the tree in image 1. is on the right. Currently the other two trees show no signs of blossoms. Other types of flowering trees have already begun to bud. 39 SCIENCE EDUCATIONAL NEWS VOL 68 NO 3 About 50 m south of the three trees, a banksia already has a large number of those familiar bottle-brush flowers – mainly a pale yellow.
