Mushroom foraging in Siuslaw National Forest

13 of our 17 species have habitat in Siuslaw National Forest (about 2,591 km² of public forest mapped). This week 10 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.

"Flushing": at least a fifth of the species' habitat in the forest is rated good or better on one of the next 7 days. Season: the middle half of dated finds in this part of Oregon (GBIF, 2000-2026). How accurate is this?

Picking rules

Rules change: always check with the forest before you go. Wilderness areas, research natural areas and some monuments are closed to picking.

Safety

Never eat a wild mushroom unless an expert has identified it in person. Several deadly species grow in these forests.
