Door County Phenology

When things are seen, week by week. Built from community-verified iNaturalist observations.

8,597 observations across 14 groups, 2023. Colour scale is fixed across years, but unconfirmed counts are not comparable between them.

Totals by Group

Observations by iconic taxon group, 2023. Both columns are counted whichever setting is active; the unconfirmed column is only added to the calendar above when it is switched on.

Insects	578	797	late July
Fungi	203	593	late August
Birds	337	254	late May
Spiders	72	80	late July
Reptiles	84	33	early July
Amphibians	54	61	late May
Mammals	34	44	mid September
Fish	52	3	late July
Molluscs	25	21	late August

Protozoans	3	19	late July
Unclassified	5	4	mid August
Chromists	0	5	late October

Unconfirmed identifications are included. These were identified by iNaturalist's computer vision and never confirmed by anyone. Their dates and coordinates are as sound as any other record — better, if anything, since they are overwhelmingly phone captures — but the species names have not been checked, and photo-based identification is weakest exactly where these are most numerous: plants and fungi.

They are also not spread evenly across the years. Community review lags behind new records, so recent years hold far more of them — roughly seven unconfirmed for every confirmed record in 2026, against one for every five in 2017. Comparing one year against another on this setting will mislead you, whatever the colour scale suggests.
