Carbon dynamics, including net ecosystem exchange, litter fall, soil respiration, plant productivity and related water uptake, are monitored along an elevational gradient. This phenocam view is of the lowest elevation, Wyoming big sagebrush, site. Snow is common, but ephemeral during the winter.

7.gb.tollgate-weir
Reynolds Creek at Tollgate weir defines an area of about a quarter (55 km²) of Reynolds Creek Experimental Watershed almost entirely comprised of the upper elevations that receive the greatest annual precipitation which predominately falls as snow. Elevations range from 1410 m to 2241 m. Vegetation is primarily sagebrush rangelands with small stands of Douglas fir (Pseudotsuga menziesii), aspen (Populus spp.), and Alpine Fir (Abies lasiocarpa) at the higher elevations
