Season Earliest year: Latest year: Trend line:

The Population trends tool allows you to display estimated annual indices of population size over time, with an optional loess smoothed trend line, for a selected time period and season (note however that trend is only calculated on the entire sampling period at each site). 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 the other optional features.
