As asked, did you use the find my drone feature? If not, have you used satellite view of your flight track to identify last location (tree)? It’s in your logs.
Good luck, let us know the results
Like the other blokes said. Just open your DJI Fly app on your device and click on Profile and then More. select the last flight and the track will come up. If you use the satellite view layer you'll be able to zoom in and narrow it down to an individual tree.
