I'm curious about how tall this tree is?

@MatthewFrawley the tallest was called Sir Vim at 88.9m tall with a 10.3 trunk girth. Unfortunately it is one of the tallest that have died from Ginger Tree Syndrome - climate change related. The one in this sighting photo is smaller but still a giant, and still alive and healthy, although there was a bit of patchy branch death appearing. One measure of drought tolerance is based on leaf osmotic potential at zero turgor (Ψo). Species with greater drought tolerance have a more negative Ψo. For example from most to least drought tolerant based on Ψo: E.microcarpa > E.melliodora > E.globulus (subsp. bicostata?) > E.maculata > E.pauciflora > E.viminalis.

Thanks for the extra information @Steve818 and I love the Big Eucalypts of Tasmania collection you have started. I'm going to mention it on Facebook, if that's okay with you.
