Glenorie – Ironbark/Turpentine Forest

Out the back of Glenorie Primary School is a very small patch of the Ironbark/Turpentine forest that once covered much of this region. There are still reminants scattered around including Cattai NP though the biotype is listed as critically endangered. The forest needs relatively high moisture and clay soils. It usually lies close to the equally endangered Bluegum High Forests. One example of which is found in Turramurra. Its quite an unusual environment and I love the fact there was a whole heap of Flax lillies covering the ground at both sites I visited. Whilst they are not currently in bloom a type of orchid called Caladenia catenata or White fingers is. This particular species uses insects as a means of pollination and does so in a quite violent fashion. The insect is once alighted is launched via a spring motion onto its stigma and becoming stuck to it struggles violently to escape. In doing so it takes pollen masses from the anther and smears them over the stigma. (30d, 180mm, f11, 1/160, iso 1600)

The second picture is a little odd for me as its unusual that I take bird shots. This bird was pretty cool and was assumedely trying to keep me away from its nest following and squawking at me. The Grey Butcher Bird, Cracticus toruatus, derives its name from wedging its prey into gaps in trees or on sharp sticks to help it dismember it or save it for later. (30d, 180mm, f5, 1/2500, iso 800).

The following post will be of some of the cool bugs I have found on the past couple of walks.
