Total search effort for box turtles by USGS EESC in 2020

Detailed Description

Numerical values and colors represent the total frequency of observer passes through the center of each grid cell during the 60 d of survey activity (1–4 surveyors each survey day) by USGS EESC in 2020. For example, a value of 40 would mean that a given grid cell was searched 40 times during the season. The buffered track lines, outlined in black, show the search path of one surveyor on Day 5 in the Stickel plot (northwest region) and Day 58 in the Snowden plot (southeast region). The black dots represent capture locations of box turtles over the season. Credit: Royle and Turner 2022.
