When I was teaching at Washington State University, I collected beetles. Then I got older and my back worse, and I found wild flowers a lot easier to photograph. So I donated my Coleoptera collection to the Department of Entomology at Texas A&M University (over 24,000 pinned and labeled specimens, most of them identified), retired from teaching, and moved to the small town of Del Norte in the San Luis Valley of south central Colorado. My current preoccupation is with wild flowers (Gymnosperms and Angiosperms) of that valley or, more specifically, of the Rio Grande drainage in Colorado.

My current project, then, is an online inventory of that drainage, Flora of the Rio Grande Watershed in Colorado https://floraupperriogrande.com/. Currently it lists 1,317 species, categorized as definitely present in the drainage or maybe present but needing verified documentation. Some 870 of the species are accompanied with photographs from the field—a number that is growing as contributors add to it. The site has a multi-field search with eight fields that can be combined:

Status (native, exotic, adventive, etc.
Earliest date recorded
Latest date recorded
Ecosystem (aquatic, basin, foothill, ruderal, urban, etc.)
Geobotanical region (Lower Basin, Culebras, South San Juans, etc.)
County that contains the drainage at least in part (Alamosa, Costilla, Conejos, etc.)
Pass (Wolf Creek, La Manga, La Veta, etc.)
Wildlife preserve (Baca Wetlands, Gread Sand Dunes NM, La Botica, etc.).

So, for instance, a user can search for plant that are exotic and recorded from the foothills of Saguache County.

So the main intention of Flora of the Rio Grande Watershed in Colorado is not to help people identify a plant (iNaturalist can do that). It is to maintain a current and ongoing catalogue, as accurate as possible, of plants in a major drainage of the state. The foundational list derives from vouchers in herbaria, augmented by photorecords of occurrences in the field.

At the moment (March 2023) I am beginning a systematic uploading into iNaturalist of photographed species that represent new state, county, or drainage records.
