Galls are a plants reaction

Galls are a plants reaction to an external influence, for example, a gall wasp, a virus, mite, bacteria, fungi etc. They are amazing things and more information can be found at http://www.british-galls.org.uk/

I am trying to get all UK plant gall postings in one place



This will hopefully increase the "visibilty" to people interested in plant galls and increase identifcation/confirmation rates

There are cureently over 500 records collected

Could you please tag any plant gall records "plant gall" or "plant gall causer" - without speech marks

Thanks in anticipation - appologies if you get multiple requests as I am trawling through past records.

If you feel reasonably confident in your id why not go to "other observations and confirm them - Following Derek's advice - if you go here to get to the next record for the same species just go to the top left and click next
