Sorry, off topic, but loosely following the line of "why isnt someone doing a study?"........
We have to remember that research usually continues
ad infinitum..........there's often no silver bullet so the problem wont always go away........for WAs Jarrah, its probably been around for much longer than many think.........but I havent studied it in great depth. I do however, recall dieback in WA forests being heavily researched 25 years ago when I was at Uni studying Forestry....jointly funded by the industry, government and Uni's......
There was a period through the 90's when the forestry profession & industry were hunted out of WA....I think it was by your WA branch of the Australian Medical Association who won a State election after WA Inc. ......they knew so much more about forest science apparently.............
I see there's a Native forest based industry back there again and it looks as though there's a fair bit going on with Jarrah dieback......Just had a quick look and here's a useful link which you can navigate around & find whats being studied and how its prioritised.............google dieback.org.au
As for Crimson finch research.....did anyone get their questions answered at the count?
