Wild berries in Južno-Banatski

Ripening dates here are computed from accumulated warmth rather than from the calendar: in a cold spring the berry ripens later, and the model follows that. But the thresholds themselves are chosen rather than measured against field records — we are confident about the order of species and still owe you the exact numbers.

And the thing that matters most: no page on this site gives you permission to eat what you found. The lookalike comparison above tells you what this berry is confused with; it does not confirm that what you are holding is that berry.
