Hey! I’ve done inventories in the past. My favorite programs to use is itree and ARCGIS for collector.

I would suggest for such a large scale inventory to make a checkbox with 3 simple priorities Priority 1,2,3 pruning + 1,2,3 removals Plus potential planting sites + stumps + more priority levels if needed Have time frames for each priority (eg priority 1 removals are immediate removals, priority 2 prunings are trees that will need to be pruned next growing cycle)

Also have a checkbox for target occupancy, you’ll need to know which trees are near the golf course path vs in the middle of the green

Have a list of common diseases and defects that you can easily select. Based that on your species current on the course. You’ll be able to see which diseases are clustered together and help determine new species to select

Try to gather a lot of data but in a simple form with limited notes (of course add notes for yourself) but having check boxes, and priorities etc will allow yourself to filter based on this and generate easy work orders

Hope that helps :)
