Purpose

These data were collected to better understand the demography of Giant Gartersnakes in the Sacramento Valley. The Integral Projection Model was constructed to identify which life-stage transitions (e.g., survival, fecundity) have the greatest influence of the growth rate of Giant Gartersnake populations.
