Would be a good idea to make a code for each of these (and others) so you can annotate maps of your AO. Put a little work into improving these stands, or adding others in the area.

In an emergency situation, scavenging for food, is much easier to do if you know where specific items are.

The collection of foods, and guarding of these gathering parties could be a good task for "second line"/"auxiliary" forces. They could be part of a logistics team that keeps "first line" militia forces in the field well fed and supplied. They could also provide valuable intel on enemy activities and movements.
