I haven't seen this clip before so, thank you for sharing...!
Spalting, has always been a very interesting subject to me and since I moved to this location 8 years ago, I have been astonished by the variety of local woods that dye and spalt tremendously fast. If fact so fast that, I have left some behind to spalt a little more and by the time I have returned a year later, is already too late, the wood has completely rotted...!
This off-course changes depend upon the density of the wood species, some species, such as the White and Silver Wattles, have a life expectancy of less than 20 years, most will be attached by white fungi before they reach 10 years of age, that will attack the tree at its forks/joints first and therefore the tree simply snaps its main branches in a mild wind storm.
Anyway, I could be here until Christmas talking about spalting, I don't have a degree like Sara but I have been following and working with spalted trees/woods for "some" time...!
Some time ago, I have created a thread here on IAP about spalting, there are pics and a video clip showing, some of the creatures that live in the moistured/wet wood and that all contribute to the spalting, have a look in
