Making observations of the amount of damage that the leaf-mining moth has done to trees, means that you have to remember to submit what you saw and where you saw it when you get home and turn on your computer.
What would be perfect would be if people had a little device to make those records while they were looking at the tree. It would be even better if it would record their location automatically, and even allow them to submit a photo of one of the leaves, while they were there.
Aha! Smartphones would be the perfect tool!
...And so was born the idea of the LeafWatch app.
