The Annual Indices tool allows you to display estimated annual indices of population size over time, with optional best polynomial fit trend line (with trend estimate) or loess smoothed trend line (without trend estimate), for a selected time period and season. Plots for multiple locations and species can be displayed at once. You can start by selecting a project, and then one or more area, and one or more species (you can select multiple areas or species by holding the CTRL key), as well as some other optional features.
