Moreton Bay Regional Council

 This blog was originally posted on the 1st of December 2010 and the green wording was added on the 7th of December 2010. New photographs have the date below them to distinguish them from the originals which were all taken on the 1st of December.

It is always reassuring to see your local government (council) hard at work, but there are times when you have to wonder if there is anyone up there in head office making any decisions, or should I be asking that question in another way.

In one of the local parks in Leis Parade in Lawnton they have just done some wonderful work on restoring part of the park. The section I refer to is a seventy to ninety metre stretch that runs along the bank of the North Pine River. This section of the bank is at a turn in the river and it cops the full force of the river when it floods. They have planted some new plants, mostly smaller grasses and little shrubs and spread a truck load of bark chips. Oh, and they cut down a gum tree.

The cut down version of a gum tree

What's that I hear you say, surely they wouldn't cut down a gum tree in the middle of a koala habitat; would they? This was quite a substantial tree, about 600mm in diameter almost a metre from the ground and right on the bank of the river. I can only imagine that some koala has written to council complaining that the tree was obscuring their view, I mean why else would you cut it down. Of course you're right, silly me, where else would they get their bark chips from to cover the bare ground where the river had washed away some of the soil and grass. Very remiss of me. In the old days I would have been sentenced to carrying night soil for a month for saying such things about our beloved council.

Now let me see. What's the date today? Ah yes, first of December in the year of 2010. What's that I hear outside, precipitation, good heavens, is it the rainy season already. I do hope those koalas down at the park have some trees to climb. If it rains for another hour or so they are going to need swimming lessons.

We have known for a few years now that trees hold the banks together and help stop erosion. And in this case provide some food for the furry ones. The first time we get a decent bit of rain, all those plants and the nice bark chips are going to be relocated. I'm sure that some early primary school children would have a better understanding of the principals involved here with regards to erosion, the environment and koala habitat.

You can see what happens when there is only a small amount of rain. Look at the difference with these supports for the rail bridge. The weather forecasters are telling us that heavier falls are expected later in the week. What will the result be then?

These pictures show the supports of a rail bridge a hundred meters from the bank of the river back behind the photographer. You can see where erosion has occurred at the base of some and debris is piled up against the others.  
The gravel that was placed around these posts is the same material used on railway tracks (and was probably placed here by Queensland Rail) and yet it is moved so easily by the water.

And here is another photograph looking from the rail bridge back towards the river where some erosion is taking place and the lovely repairs were done. You will see a rise in the ground between the two trees were the river gives the park another top dressing of river silt and small gravel every time it floods. By the end of this rainy season you should see all of the material our wonderful council has placed at the far end of the park (you can just make out the brown bark chips at the end of the lawn) somewhere close to the photographer's feet.

The photograph on the right is looking in the opposite direction to the previous photograph. Look at the new top dressing of river sand, silt and those wonderful bark chips. All that money spent by our wonderful council spread somewhere else six (that is 6) days after it was put down.

Well done council.

What was that scheme that was brought in by, I think it was Gough Whitlam, where people had to work for the dole. What a catastrophe, and yet, it was managed better than this bit of gardening.
