To “document” an earthworm-free location you need to do 3 things

1. Write down the date and location of where you attempted to collect the earthworms.

   The location information should be either…

   1. a “legal description” (township-range-section, sub-section), or
   2. the UTM coordinates (if you are using GPS), or
   3. the latitude & longitude.

   A good description of the directions to it is also helpful (ie. 100 yards into woodlands on the east side of country road 12, 1 mile south of the junction with Shilhon road) with a short description of the habitat type (Sugar maple forest, shrubland, Oak savanna, prairie, city park; etc.), soil type (sandy, clay, rocky, steep slopes, level, etc.) and conditions (old & undisturbed, heavily used, wet, dry, etc.). Alternatively, you could include a general or detailed habitat survey and include this with your earthworm information. The more context information we have the more useful the data is!

2. Write down how you attempted to collect earthworms in your site.
   1. Mustard extraction
   2. Hand digging
   3. Flip & Strip

   See instructions for how to conduct earthworm surveys for details on these sampling methods. You could also include a short description of the conditions where you found the earthworms you collected (ie. under a log, parking lot after rain, deep in soil, on the surface, etc.)

3. Send your information to...
