With an app in your phone, you can assess damages on tree stems.
The user add some basic facts: the age of the tree, average diameter, site, share of trees chewed and some more. The app computes how much you will loose in money at felling compared to the same stand with no damages.
This gives the forest owner some advice and makes it possible for her to test different scenarios. Plus, it pays attention to the damages made by animals to the forest, which, due to the researchers, is important.
