Annual frequency graphs

The following graphs provide the annual pattern of frequency (proportion of surveys where a species was detected) based on data associated with this project only. To view more advanced options as well as data from other projects, you can go to the NatureCounts data summary page. Please note that these graphs do not necessarily reflect actual trends in the species population and may be subject to various reporting biases and changes in methodology along the years.

You can restrict the bar charts to only some of the datasets that are part of this project
