^..yes, thank you for spotting that..ridiculously, i've never properly re-read or checked the OP !
A. acuminata is found predominantly in WA, and is described as such later in the thread..also, in the OP, i would have been including subspecies burkittii, or A. burkittii, which extends the range through to western NSW, and is widely distributed in central inland South Australia, as well as WA..thanks for being sharp Sharps

is fixed..
always appreciate typos or errors being pointed out..
^...^speaking of..those various species percentages posted earlier Orion1..in all cases, except acuminata, adding a decimal point would get nearer the ballpark..but as pointed out, one or two reported results do not mean that's what will definitely be in the plant..
potatokorpse thank you for your experiment in the pursuit of knowledge ! yes it is known for excess water and phosphorus to decrease alkaloids in some plants, and for water stress and nitrogen to increase them..
i assume that you checked the method with a known, positive, control..

and bbing..i appreciate your sentiments and comments..thank you both of you..
yes, i can only the hope the long term negative consequences of such destructive actions are becoming clearer to the people who would do or did this..
CosmicSpore, -Shadow, and DreaMTripper..you people are solid!
and Seldom, thanks for the heads up earlier on the golden wattle..
..the above mentioned tree destruction/exploitation actions have put me in a highly meditative mood of late on the topic of acacias (and in quiet discussion of actions that can discourage such behaviour) ..and spiritual matters, of course..and time to work on book..
Acacians, and the eco-conscious generally, may the joy of trees illuminate..and mutually sustain..
respect to the trees
