Xavier,
California tiger salamanders are federally listed as "endangered" in Santa Barbara County (where I did my graduate research) and a "threatened" species throughout the rest of CA. Because of their status, developers are required to have surveys done as part of their permitting process to find out if salamanders are present on their property. I have a permit that allows me to do aquatic sampling of vernal pools (looking for salamander larvae). I can also do drift fence surveys for them as well. A drift fence is a 2-3 foot tall fence, usually made out of silt fence, with buckets buried along the fence. Animals passing through an area hit the fence and walk along it to eventually fall into a bucket. Thankfully, not all the work I do is developer/construction related. Just last week I spent 3 days in San Luis Obispo County working on a contract from the US Fish and Wildlife Service. California tiger salamanders were last documented in San Luis Obispo County in 1939, and we are trying to find them there again. I was dip netting a bunch of ponds to look for salamander larvae. No salamanders this time, just lots of Pacific treefrog larvae. But the habitat certainly looks good!
We just moved north the the Sacramento area, and part of the reason was so that I would be closer to the salamanders. We used to live in Orange County, and the closest salamander population was 200 miles away, so my salamander skills weren't doing me much good!
Matt,
Very cool! A friend of mine found 2 new California tiger salamander breeding ponds in Calaveras County this year.
