check endemism status if its really right

[ajrominger]

Right now VO has most single island endemics. Is that really right?

• look at just native (or endemic) v. non-native or non-endemic
• compare that to single island endemics that we have calculated

Relates to looking at METE deviation versus prop invasive #4

[ajrominger]

per island info might be more about how extensively the island has been studied: 49be22e.

perhaps we just want to remove this analysis, data source might not be reliable enough
