"Amphibian reproduction is strongly influenced by ambient temperature and precipitation thus making amphibians strong potential indicators of biotic response to climate change. The Mohonk Preserve's Daniel Smiley Research Center have been monitoring species occupancy, reproductive success, and water quality of 11 vernal pools (Ski Loop, Bonticou, Terrace, Long Woodland Pool, Long Woodland Swamp, Oakwood, Sleepy Hollow, Hermits, North Mud Pond, Canaan, and Talus ) on the Preserve each spring from April 1931 to May 2019 (present). Data collection has included species, egg mass, and tadpole counts; weather conditions including precipitation, sky and wind codes; and water quality measurements including water temperature, pH, and depth. Collection of data was sporadic from 1931 - 1991 but has been collected consistantly from 1991 to present. We also began monitoring dissolved oxygen, nitrate concentrations, and conductivity of the vernal pools using a YSI Sonde Professional Plus Instrument and turbidity using a turbidity tube in February 2018."
