Arroyo Toad ID Confirmation.

Post by RobertH » October 28th, 2016, 8:01 pm

So basically a friend of mine at school took this picture of a toad while he was fishing. He has a pretty good knowledge of the native fauna that lives in our watersheds, but when he told me he saw an arroyo toad I was pretty doubtful. But then he showed me this picture he took of it and it actually does look like one. The location he found it at is also not at one that is on any report you can find on google.

It looks like the picture on CA. Herps. for the Arroyo Toad.

I would say that's a positive ID....

Definitely an arroyo toad. New locality, just shows what's still out there for those willing to go look.

Yep looks like A. californicus to me, but once Dr. Sweet has given his opinion, mine seems a little pointless.

Indeed, that's very cool. Just goes to show you, "please, just try". Was that friend fishing at night for catfish, or what? Sitting around quietly in the dark next to some water, letting the local anurans come out and show themselves, sounds pretty fun.

cheers

Thanks for everyone's replies.

In the meantime, I had mailed Sam Sweet and he had already confirmed to me that this is indeed an Arroyo Toad - and from a new locality! As to the specific locality, I can only say that it's a very remote place on the coastal side of the San Gabriel Mountains.

We'll enter the toad into the HERP database and also report the find to the CDFW and to the US F&W Service, as Sam has recommended.

Jimi, you had asked how the toad was found and when: The toad was found around 3 pm in the afternoon, so not at night or in the dark. It was apparently sitting by the side of a stream in bright daylight when Nicholas's friend, an avid fisherman, spotted it (and later several others).

Thanks for the additional story, Robert. It's nice to hear that several were seen.

Incidentally, the pic just looked like it had been taken in the dark - that's what got me started down that path.

I wonder what this find will mean for CDFW trout stocking & eradication operations. Will be interesting to watch. From the outside, anyway...

cheers

Trout don't seem to affect arroyo toads much, although trout fishermen do. Long ago (pre-listing) I sat and flipped tadpoles to foraging trout, and the fish ignored them. Sunfish in the daytime and bullheads by night, and sculpins any time all enjoy toad tadpoles, but trout seem to be in the clear. What is NOT cool occurs when fishermen tromp up and down the stream and walk in the shallow water rather than on shore. Doing so they crush or displace many arroyo toad clutches.
