Going on a county level, Sonoma County and the adjacent part of extreme southern Mendocino County are a pretty major biogeographical transition zone for herpetofauna, especially amphibians. So you’ve got several taxa that reach the southern extreme of their range right in my neck of the woods, but there are few to no iNat observations from this area. I’d absolutely love to fill in that gap.
Top of the list are the Wandering salamander (Aneides vagrans) and Northwestern salamander (Ambystoma gracile). Both can be found along the coast in northwest Sonoma County. The Northwestern salamander is especially tantalizing because there is a population in and around Salt Point State Park that’s only been observed a handful of times – most recently this past winter by @jeweliha (https://www.inaturalist.org/observations/19900334)
It’s an interesting habitat. The salamanders are almost certainly breeding in sag ponds on the San Andreas fault. I hope one day I’ll be lucky enough to encounter one.
Other local dream herps include the rubber boa and mountain kingsnake. A tailed frog would be pretty cool too.
I’m a huge cicada nerd, so I always have an ear out for songs when they are in season. I have probably encountered most if not all of the local species, but in many cases that simply means I’ve stood underneath a tree where one was singing, but had no way of capturing or even getting a look at the darn thing to identify it. Many of my daydreams involve finally getting my hands on a cicada that I’ve been hearing up in the canopy for years.
