THE PROBLEM
Tree-of-Life knowledge
• Mostly locked in pics• < 5% of trees archived • Hard to discover & access
Researchers, educators, & resource-providers who could use a good
species tree
?
What big-tree methods generateWhat users need

Goal: access to expert ToL knowledge that is convenient – much easier than DIY tree computable – logically encoded trees (not
