Mushroom foraging in Umatilla National Forest
11 of our 17 species have habitat in Umatilla National Forest (about 4,125 km² of public forest mapped). This week 3 of them are flushing somewhere in the forest. Updated every night from the weather forecast.
Where the habitat is
5 km squares: darker green means more of the square is habitat for at least one species. The map shows the zones at 250 m.
