Summary

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. These data support the following publication: Rose, J.P., Kim, R., Schoening, E.J., Lien, P.C., and Halstead, B.J., 2023. Comparing reintroduction strategies for the endangered San Francisco gartersnake (Thamnophis sirtalis tetrataenia) using demographic models.
