Here is the R code I used to make a Gannt chart displaying a muli-taxa wildlife monitoring timeline with different survey types. It's based on the code from: https://www.molecularecologist.com/2019/01/simple-gantt-charts-in-r-with-ggplot2-and-the-tidyverse/.
My main modification is the overlapping colors to display two techniques used to monitor the same taxa at the same time.
