W. Reimer 1950 Journal 16 Feb. Calif.: Contra Costa Co, Lafayette Reservoir kept as captive. One Rana aurora taken for experimental uses. Hylla seen almost everywhere though not common and occasionally calling from hillside. At dusk, in descending face of dam picked up a number of young Triturus, some young of the year and a Cottia. 18 Feb. Calif.: Contra Costa Co, Pinchot Spent 1430- 1730 in study area. 1645 hrs: air 11.4°C, water 8.4°C. Weather clear and sunny. Batrachosaps under every piece of cover. 10 Ensatina seen, many small. Water now clear with good flow. Walked downstream perhaps a quarter mile to determine if Triturus population below study area (out of redwoods) any more dense than in area, and also to see if any marked animals had moved or been washed downstream. Triturus noted only in two spots in stream, such spots near open grassy slope and oak woodland. In rest of area only tangled thick mass of shrub-like vegetation present near stream. No Triturus in these areas. Will they remain absent even later in season?
