Hi there :) 

I appreciate that you want to improve the database, but please do not delete useful information. While the species=palm that was added by EveryDoor is wrong, I can later change that tag to a beter one, e.g. taxon:family=Arecaceae. When you remove that information from the trees, it means that I will need to resurvey all those trees in the area I look after. 

Thank you.
