Hi there I-Naturalists!
I'm a full-time I-Naturalist, avid hiker-traveler, plant-finder, bird-watcher, bug-seeker, herp-lover--which takes me to many interesting natural places where I enjoy taking WAY too many photos. I love nature and find all living things fascinating and worth studying. I appreciate all comments, corrections and confirmations to my observations, and I look forward to seeing your sightings in nature too. I-Naturalist tip: The more Projects you join that match your interests--the more expert eyes will see and confirm your observations.

As a former research/reference librarian, I'm always thrilled to share new learning tools. I hope you will discover some interesting print and online, mostly California-focused, Nature Resources below to help you verify and learn a bit more about your species sightings before and as you add them to INaturalist. The INaturalist app and Seek app can be useful tools in the field for a quick, but only tentative I.D. of species. A.I. (or Computer Vision) isn't that reliable or perfect yet!
