I am slowly putting together a very basic identification key of plant damages, to determine first if the source of the damage is living or not, and then what did it: bacteria, fungi, insects, mite, small/medium/large mammals... I was quite surprise at the first place to not find such material already produce.
I hope this material to be used by parataxonomists in Central Africa. It should therefore be accessible and well-illustrated. It also do not need to go too much into details: for example, to conclude the key at 'Insect' is fine, we do not need to know which Order of Insects did it.
I have seen quite some apps and other websites for cultivated plants, but none are quite as simple and general as what I am looking for. Maybe I was simply looking at the wrong places.
Any suggestion is welcome. Thanks.
