San Francisco Gartersnake Fecundity Data from San Mateo County, California Collected from 2019-2022

August 30, 2023

Adult female San Francisco gartersnakes (Thamnophis sirtalis tetrataenia) were captured and examined using an ultrasound device to determine if they were gravid and count the number of embryos in those that were. Morphological data including length and mass were collected for each snake, along with the date of capture and a study site identifier.
