The good news about Robbie the Bittern just got even better – he’s decided to visit the Long Swamp Restoration Trial!

If you are one of those people who like stories of synchronicity, or meaningful co-incidences, then this blog update is for you…

As if Robbie the Bittern making a bee-line for Pick Swamp, directly from the rice crops of the Riverina where he was born and bred, wasn’t good enough… he decided to take in some sights near the Glenelg River mouth (within a very short distance of a spot mentioned in this recent blog), before flying down the coast to – you guessed it – Long Swamp!

But it turns out that Robbie didn’t head to just anywhere in Long Swamp, he flew straight to the wetland in the immediate vicinity our our restoration trial at Nobles Rocks.

The location of the weir structures associated with the three phases of the Long Swamp restoration trial at Nobles Rocks – the very area that Robbie has decided to fly to for a look around!

For two concurrent and previously unrelated conservation projects to come together like this, when one of those projects started over 500 km away in NSW, I reckon is a pretty amazing, meaningful coincidence!

Now he’s oblivious to all the fuss of course, but Robbie is quickly becoming our highest profile touring ambassador for wetland restoration!

In case you are wondering, this is what he is seeing at the moment around the Nobles Rocks area:

Let’s hope Robbie sticks around a while longer, because the trial at Nobles Rocks is now really starting to get interesting – and we think he might be well suited to the habitat being restored in this area.

It turns out that after a wet week in the local area, water levels in this recently restored portion of Long Swamp are continuing to rise.

Here’s how the levels have changed at our gauge board in Long Swamp both before and after the structure was completed on the 27th April:

In other words, the transformation of the swamp has begun…
