How to use KYTE
Photograph the whole tree first, then a close photo of a few leaves still on it, if you can reach them; the bark helps too. On a later visit, stand in the same place, so the two photos can be compared.
Find lists interesting trees near you: notable, NZ Tree Register, big and few on record. Walk there points the way, and the camera labels the trees so you can tell which one it is.
Saved visits work offline. The tree records for places you have already looked at, and Find’s lists once opened, stay on this phone; new places and the aerial photos need a connection.
Sign in to back up your trees and open them on another device. You choose which visits to send to ALTO. You can export your visits and their original photos at any time.
KYTE lists the trees nearest the photo’s location, and uses the direction the camera faced when the phone records it. The photos of the tree you send to ALTO (the whole tree, its leaves, flowers and fruit) also go to Pl@ntNet, which suggests a species to you and the reviewer.

Stay on footpaths, off private land and graves, and watch for traffic. Kauri are never missions.

Only show:
The lists Find opens on and the species search hold street and park trees only. Kauri are left out, and so is every tree within 50 m of one, so that no one is sent to walk their roots. A tree number finds any ALTO tree, but KYTE offers a walk only to a tree on these lists, and Take me to one picks only from them.

This tree may stand on private land. Look from the street or a public place, and ask before going in.
Is this the tree?
The record may be a few metres out, or the tree may have gone.
