just comparing your city’s observations to my city’s observations (Houston), it looks to me like you all made a lot of plant observations (like we did) but then you all had a relatively low identification rate on plant observations.
you all had lots of insect and bird observations, too, but the identification rates on those are not terrible. your mammal rate is good, too.
reptiles and amphibians need a little improvement, along with everything else, but you all made relatively few of those observations.
but at the end of the day the biggest impact to getting a better RG ratio overall would be to improve on your plant IDs. i didn’t check to see whether the issue is observations without enough evidence (ex. bark but no leaves), blurry / low-resolution photos, lots difficult-to-id-to-species organisms recorded, or lack of identifiers, but i suspect working on recruiting some good plant identifiers could make a big difference in any case.
