Foraging calendar: Wisconsin
Month by month, when people in Wisconsin record the things foragers look for: 21 species from 8,619 public observations. Darker means more of that row's records fall in that month.

Questions
When do people record mushrooms in Wisconsin?
In the public records, the busiest months are: Oyster mushrooms (Jun), Chicken of the woods (Aug), Giant puffball (Oct), Morels (May), Hen of the woods (maitake) (Sep), Lion's mane and other Hericium (Sep). That is when people reported them, not a forecast or a statement that anything is safe to eat.
When do people record wild fruit and nuts in Wisconsin?
Records of plants with fruit peak as follows: Sumacs (Jul), Blackberries, raspberries and relatives (Jul), Elderberries (Aug), Blueberries, huckleberries and relatives (Jul), Hazelnuts (Jul), Wild roses (hips) (Oct). Fruit on a plant in a record says nothing about ripeness or edibility.
Is this a guide to what is safe to eat?
No. It lists when people recorded species in public datasets. It does not identify anything or judge edibility. Confirm every find with a qualified local expert.
