Roos, Dean 2011 Journal Oct. 23 Nevado de Colima, Jalisco, Mexico Drove from Mexico City to Guadalajara with Gabriel Perra, Jorge Sanchez, Omar Becerra, picked up Ted Papenfuss at airport + spent night in Guadalajara. This morning, drove to Ciudad Guzman, then across highway on road W that passes Nevado de Colima. Took small road S toward El Fresnillo, then a small dirt road up the NE side of Nevado de Colima, which follows one of the aqueducts and eventually reaches the refuge landings. We went to one of the first points w/ pine-oak forest (19.58873°N, 103.55711°W [279m], 2527m elev) + searched from 14:00-16:00 but found nothing. The forest has about an even mixture of pine+oak (mostly oak in some areas w/ a shrubby understory + some pison oak - looks like a forest in California from the Sierra foothills). The logs are wet w/in + beneath, and leaf litter was fairly wet under first layer - good conditions. It appears to have rained there recently. We drove ~1km downhill + sampled on an abandoned road. Searched along road from 17:45-19:00; I got a Stegophis in leaf litter. Habitat here looks good along roadbank (rock w/ cracks) but forest is either too brushy/steept to enter or somewhat dry. Searched again from 20:30 - 21:00 w/ lights; Jorge + Omar got another Stegophis but didn't collect it. The daytime high was around 23°C and it got fairly cold at night, maybe w/ a low of ~5°C. Oct. 24 At a late start, because we were cold, I think, Ted says he had collected salamander at 7200 ft (2200m) so we walked down lower to a farm and searched in a tiny patch of pine forest from 11:45-12:00. The forest here is very disturbed and there is no more forest downhill. Ted decided I found a Stegophis here.
