You can search for photo series sites using a large number of search variables and combinations of search variables.  Click on the toggle boxes to select search variables.  If you decide to remove a search variable from your query, select the blank box at the top of each search variable list to clear your previous selection.  Once you have specified your query, click the Get sites button.  All matches will be displayed in the lower box.  Click on a site thumbnail to view site information and associated data tables.

The example below shows all sites in the Lodgepole Pine series that include overstory species whose common name starts with "lodgepole" AND whose tree density is less than or equal to 400 trees per acre.

Tip: Because there are so many potential search variables, it is easy to come up with no matches.  If your query does not produce a match, try simplifying it or modifying numeric search variables.
