  • When you first open the website, you will see records of All Species Groups, at a 2km square resolution.
  • As you zoom into an area of interest, the map will automatically change to a 1km and then the 100m resolution of each record, if recorded at a high enough resolution.
  • If you are viewing an entire species group, darker squares indicate more different species within it.
  • If you are viewing a single species, darker squares indicate more records of that species.
  • The mapping options menu on the right will allow you to choose different species groups, individual species, and record management status and lets you lock the resolution.
  • The options along the top allow you to zoom in and out and change the background map, and submit a species record.
