We did create an Organized Editing Activity page in the wiki, it includes a description of how the process goes: https://wiki.openstreetmap.org/wiki/Organised_Editing/Activities/Yerevan_Tree_Map#Import_plan

There is no dataset to import per se.  We had around 4k trees in our local database and they are already in.  We want to send updates from now on, e.g. people with an app collect new data, on tree heights etc, and we send that data in small changesets, up to 100 nodes per hour.  We usually do weekly mapping sessions with a couple of volunteers, so there's not much data expected.  Do we still need a complex import plan described for this, with revert plan etc?
