How to Build Your Own Foraging Calendar From Your Journal
The best foraging calendar for your patches is the one your own notes draw. Log every find with its date and your own name for it, and after one season you can lay the year out by week, see which months were busiest, and print a checklist of what turned up next month last year. Regional charts and public records give you a starting point; your journal tells you about your ground.
Why a public calendar is only a starting point
Public foraging calendars, including the state-by-state calendar of public records on this site, show when many people reported something across a whole state. That is useful for knowing roughly when to start looking. It cannot tell you when your north-facing slope comes in, how a wet spring shifts your patch, or what you personally go out for.
Public records also follow people: they pile up on weekends, near cities and in good weather. A month with lots of records may simply be a month when lots of people walked. Your own journal has the same bias toward the days you went out, which is exactly why it is the calendar that matches your habits.
Step 1: record the date and your own name, every time
A calendar needs two fields above all: the date and a consistent name. Use the same name for the same thing every time you log it (pick one spelling and stick to it), so a season of entries groups cleanly. Add the category (mushroom, berry or fruit, nut, greens, herb, root) so you can see the shape of your year at a glance.
Log trips that found nothing too, in your notes. A blank outing is real information about timing.
Step 2: lay the year out by week
Weeks beat months for foraging. A month is too coarse: "September" hides the difference between the first week and the last. Number the weeks of the year from 1 to 53 and place each find on its week. Laid around a circle (January at the top, clockwise), the year becomes a wheel, and the clusters show your seasons at a glance: a spring knot, a summer run, an autumn ring.
| What to look at | What it tells you |
|---|---|
| Where the marks cluster | Your own seasons, by week, on your ground |
| Gaps between clusters | Weeks you did not go out, or went out and found nothing (check your notes) |
| The busiest months | Where your effort went; compare with last year |
| The same name across years | How consistent a find is from year to year, by week |
Step 3: compare years, not single dates
One year of notes gives you dates. Two or three give you a window. If you logged something in weeks 35 to 37 in two of the last three years, that is the window worth planning around, and the year it was missing is worth a note about weather.
Step 4: print a checklist for next month
Before a new month starts, list what you logged in that month in earlier years, with the weeks you found it and in how many years. Leave blank columns for the date, the patch and notes, and a few empty rows for anything new. Take it into the field and fill it in with a pencil. Then log the finds properly when you are back in signal.
Keep patch names off anything you share. A list of names and weeks is fine to show a friend; the places are yours.
Step 5: share the year, not the spots
At the end of the season a year in review (total finds, distinct names, busiest month and a wheel of weeks) is a good thing to post or send to the friend who forages with you. It says what kind of year you had without saying where.
How Forager's Field Notes does this. Forager's Field Notes builds the year wheel for you from your own journal: one mark per find, placed by week and stacking outward, with your busiest months and the names you logged most. Share it as an image card that never shows a patch name or a location. With Field Notes+, the field checklist lists what you logged in any month in earlier years, with the weeks and the years, plus blank rows, and shares or prints as one page. Everything is worked out on your phone from your own finds; there is no account and nothing is uploaded.
