Save the conker..

Let's hope this app gives the boffins enough info to save our horse chestnuts. I noticed this discolouration on the leaves in spring and wondered what it was. I'm glad they have found a solution to the alien moth.
To the person that gave one star, either you did not understand what the app is or you're a miserable so and so!

Citizen Science!

Great app. I love the idea of 'citizen science'.

One reviewer suggested that you can't submit more than one photo a month. That's not the case at all. The instructions say "You are welcome to submit as many records as you like throughout summer, but please only create 1 record per tree per month."

Simple way to help track pesky pests

Simple to use in the field, and very obvious what to do. Take a photo, rate, and upload. Hope they find this information useful.

(Was having issues over the weekend, but all working now.)
