How to search from the Database

  • Start choosing 1-2 selections best describing your needs (on the left column) and Click on 'Search' just below the 'Report options'.
  • Then make one more selection and repeat the search
  • As the different search criteria must all be true it is easy to end up with no experiments found. Then just click on 'Reset form'
  • Experiment with different criteria. Help and explanation on each choice is available by clicking the '?' next to each popup-menu.

The selections

  • The seven menus in the first select-group list all different values from the database followed by total number of experiments for the text like Abies (4).
  • It is possible to search by some numeric values. However there are still some missing values in the data. Because of this the search might not find some experiments
  • The next two choices make it possible to search in numeric fields for values/ranges.
  • With the last search the rest of the text variables can be searched for exact (is) text or for substring (contains).
  • There is a vertical line dividing the menu-area and this help. It can be adjusted for most convenient view.

About Reporting Options and Results

  • There are a three choices (1000, 500 and download to Microsoft Excel/any spreadsheet program) for the number of experiments returned. Experiments are shown on pages of at most 20 experiments.
  • Click in the corresponding checkbox to extend the search with terminated experiments. They are shown on the map with slightly lighter color. Default is not to search terminated experiments (Priority T).
  • There are 26 variables in the database, you may define your reports by clicking the 'Define Report Columns' -button
  • The approximate locations are displayed on the first report page on a map (rounding effect up to 10 km in the data). This is the default and can be changed by removing the check in the 'show results on map' box.
  • You can see all fields for the experiment by clicking the orange number in the start of the report-row. Or you can check the box for interesting experiments and click the 'List selected experiments' button to see details for several experiments with less clicks.


The list is seen on the search menu. Short names for subject fields and objectives are also included as keywords.

Tree species

The list is seen on the menu. Search by partial name is possible with text search on bottom of the search form.
