Abundance scales

As with species lists, an abundance scale lookup table eases data entry and helps to keep the data consistent. A default lookup table comes with the install but custom lookup tables can be imported from tabular text files that can be edited and exchanged between devices. A link in the action bar displays the active abundance scale and links to related functions in the menu.

We are grateful if you provide other scales regularly used in your area.

If you want to import your own scale you can download the original file, edit and re-load it (menu: Lookup > Cover scales > Load from disk). The table consists of a textfile with tabular data of the following format:

"""01""";"""r""";1;Braun-Blanquet (old)
"""01""";"""+""";2;Braun-Blanquet (old)
"""01""";"""1""";3;Braun-Blanquet (old)
"""01""";"""2""";13;Braun-Blanquet (old)
"""01""";"""3""";38;Braun-Blanquet (old)
"""01""";"""4""";68;Braun-Blanquet (old)
"""01""";"""5""";88;Braun-Blanquet (old)
