UC Merced Vernal Pools and Grassland Reserve Piezometer Data 2015-2016

Two sets of three–vernal pool series were chosen based on geomorphology, as well as 4,254 elevation and GPS survey points. Each catchment contained one series of three vernal pools, which consisted of an upper, middle, and lower vernal pool, and all pools were of cascading elevation. A monitoring well and piezometer were installed at the lowest elevation of each vernal pool. An additional monitoring well and piezometer were installed upland in each catchment. Model 3001 Junior M5 Leveloggers (Solinst, Georgetown, Ontario, Canada) were deployed in all monitoring wells and piezometers. The Leveloggers and Barologger were programmed to sample every hour. They were left unattended until the end of the season for collection. Data collection was for WY 2016. Precautions (particularly in capping the wells and piezometers and being sure they did not protrude more than 10 cm above land surface) were taken to make sure deployed field equipment and installations were cow–proof.
