Yesterday and today I spent time taking pictures of plants, identifying them (initially with Google Lens and then with the National Audubon Field Guide to Trees and the iNaturalist site), and then posting the ones I could identify to the iNaturalist site. A good advance on my naturalist skills. I listened to a Tim Ferriss podcast, I do not remember the guest, but that guest had advised Tim, who likes nature walks and wanted to make more identifications of what he saw, to start with trees. There are fewer different species than for other types of plants. I may start to focus on those as well for the same reason. If can be overwhelming to try to identify everything you see on a walk through nature.
