2017 May 28--Serpentine Site in Upper Quines Creek

Two years ago, 2015, I saw this rather rocky, barren spot on Google Earth and decided to go take a look. In late March and late May of that year, I visited the site with Jimmy Billstine, looking for birds of interest. On the May trip we were successful in locating Poorwills, one of our target species. No other specialty birds were found, but it was clearly an interesting site and worth additional visits. On the first trip we accessed the site via the Quines Creek drainage, and the second trip via the Starvout Creek Drainage. The last leg of either route is not recommended for low-clearance vehicles, though you can get closer with a passenger vehicle by going up Starvout Creek. The east side of this serpentine site is on BLM land, while the west side is private industrial forest land.

On May 28 this year I went alone to look for Sagebrush Lizards! I am uncertain at this time if there are historical records for the species in Douglas County or the Umpqua Basin, as some published range maps show different boundaries (some crossing Douglas County, some not), but based on their habitat preferences and range, I figured that if Sagebrush Lizards did occur in southern Douglas County, this site would have a high likelihood of having them. I also figured I would enjoy some interesting flowers at this unusually large, open serpentine site.

The site has abundant exposed serpentine rock and very little soil. Dominant trees include Jeffrey Pine and Incense Cedar. Buckbrush, Canyon Live Oak, and Dwarf Silktassel are present, and numerous rocky site plants; otherwise, in this 6-hour visit I did not find any rare plants (that I know of). I was surprised to find a half-dozen Monadenia species snails (probably M. fidelis). Click on the landscape photos below to get a 360 degree look at the site.

As for the lizards, they were nowhere to be found in the early morning, but by about 10:00 and 75-80 F degrees, small Sceloporus sp. were scurrying this way and that to hide in the brush as I approached. These remained unidentified. However, all of the small and large lizards I adequately observed and/or photographed were Western Fence Lizards (see the many photos). While I can't say there aren't any Sagebrush Lizards here, the abundance of Western Fence Lizards lowers my expectations and hopes of finding a Sagebrush Lizard here. But if they are not here, I wonder if they are anywhere in southern Douglas County? After all, I thought I picked the best looking spot! Well, who knows? I'll have to try a couple other locations, and I've got a couple in mind....

Here is a bird list for the visit (some birds in the list were heard from the open serpentine area, but were in the nearby forest), and see below for documentation of some of the life I observed (click for more info and additional photos).
