The info here is rather like a system of checks and balances, David. By being open forums, posted information is seen by anyone reading. If there seems to be some misinformation/mistaken ID's, etc, it will be questioned, corrected and/or explained or changed.
There are moderators for the different areas and a wealth of anecdotal experience and info from the members here. The Moderators work to ensure that info that goes into the Plant Data Base is accurate .
The site is owned and operated by Dave and Trish Whitinger.
