Gday Taipan!
Sorry for the delay in responding to your Ghost Gum query - I've done a little bit of STFWing, and the short answer is "I don't know". Give it a go, I say. Nice pic, BTW.
While I'm here, I thought I might as well post a few more pics in a vain attempt to keep the viewer interested. Please find attached photos of some River Reds in Mill Park, in Melbourne's outer Northern suburbs. Some of the best examples of mature Redgums can be found in here. This area has been pasture for a number of years, and is quickly becoming over-developed into suburban sprawl.
I am of the belief - the hope? - that the remaining Reds are protected. Being protected is one thing, but have a look at how close the construction is to these ancient trees... >( Can't be good for a very old root system. The developers might learn a lesson or two once these big fellas start dropping 500kg+ branches on their rooves and/or customers...
Apologies in advance for the quality of the pics - 'twas a little overcast, and - try as I may - I was unable to frame out the obvious signs of 'civilisation'. Hopefully they show enough to be of some inspiration.
Thanks.
FlyBri.
PS: I hope to update my project tree pics soon...
