Willows: choking pools or creating them?

Willows are said by some to ‘choke’ pools and streams: check here, here and here.

Apparently that’s one of the reasons they’re so terribly bad for platypus; like the one in this video.

Then again, the platypus pool in this video is actually created and maintained by a bank of willows, you can see some of them in the background. These have colonised and aggraded the ‘floodout’ of deposited sediment at the pool’s downstream end (shown in the clip). The pool is approximately 150m long, averaging 4-5m across and is about 160cm at its deepest point. It lies within an incised section of Monkittee Creek which is well-lined with willows. Platypus are regularly sighted in this pool, sometimes two at a time. Continue reading

Nativist affronts to logic: they’re everywhere

No one should have to read this stuff (though it is everywhere and very hard to avoid), but if you are going to read it you should be made to practice critical thinking throughout. Then again, this could just make it painful for you. Non-critical thinking is so much easier; no jarring thoughts, no need to employ logic, just a comforting background hum of soothing ideology.

Where does it end?…..No, seriously…..

When you look at the wilful and wanton environmental destruction conveyed in these photographs you must ask yourself: ‘how could anyone do this in the name of environmentalism?’ After all the disturbance we’ve already inflicted upon this biosphere, how is this really helping?

In this example of willow demolition, the trees were cut down and dragged away and the stumps were poisoned. Then (for some unfathomable reason) a drainage ditch was excavated into the floodplain. Continue reading

Platypus cavorting in a ‘willow infested’ world!

Braidwood has a small population of platypus living happily along its “willow-infested” urban creeks. They have long been a feature of the town, as have the willows.

Until about 1997 these creeks had virtually no native vegetation. Around that time the urban Landcare group starting planting natives (and killing willows). But even today, these native trees are relatively-small and represent only a tiny fraction of the vegetation cover, the vast majority of which is willow (salix fragilis); others include poplar, elm and privet. This could be described as a ‘non-native’ ecosystem, but non-nativist ecosystem might be more accurate.
