Browser Requirements

  1. A reasonably recent browser (Chrome, IE, Firefox, Opera, Safari)
  2. At least 1280 horizontal pixels in browser window. Decrease magnification if necessary

Usage Hints

  1. On the data pane at left, clicking within one of the lightly shaded areas (corresponding to an MGP) filters the populations down to that MPG. Clicking again within that area (or the Back icon) restores the previous.
  2. Clicking on the name of the population displays its data all by itself.
  3. You can restrict the populations to one or more ESUs by clicking on the associated bars in the ESU row chart on the left.
  4. You can restrict the time window by clicking and dragging your mouse across the year labels on the x-axis. The span will shade gray as you do this, but you need to release the click within that axis (and not somewhere else on the screen). Not perfect, but it works for now. Clicking on the left or right arrows which appear expands back to the original limits.
  5. The map is for orientation purposes, so clicking on it will get you nowhere.
  6. Grouping together one or more MPGs or run types is possible using the pie chart filters found under the Pop/Stream/Run tab (mislabeled at present) on the left pane.
  7. The "Show" dropdown toggles between displaying only those populations for which the SPS has data and additional listed populations which may (or may not) have data in the future.
  8. The "Show All" selection in the Select Species list will indeed show all populations on one screen. It's really scary.
