Observations by Gary Fewless for Green Bay WI (Lat.N 44.51° Long. W 88.02° ), except as noted. For flowers lacking conspicuous petals or sepals I define "anthesis" as release of pollen by mature anthers.

Woodcock, Oconto Co.,Pensaukee (Tom Erdman).

Mar 20 High temp 46. Most snow is gone from level open ground, City of Green Bay. There is still considerable snow in shaded sites and where it was deeper in drifts or snowbanks. East River ice has standing water along the edges, but is still in full ice cover.

Mar 17 Robins and Sandhill Cranes seen in Manitowoc Co., Cooperstown area (Joel Trick);
Mar 16 Substantial flocks of Robins and large numbers of Red-winged Blackbirds, City of Green Bay;
Mar 15 A few Marsh Marigolds (Caltha palustris) in flower, Brown Co (Gary Fewless). These plants are in a very active 'spring' which flows all winter and prevents the soil from freezing. Consequently the marsh marigolds flower there long before most other sites. Symplocarpus foetidus (skunk cabbage), ordinarily a very early flowering species in springy sites has not yet flowered on UWGB--many plants appear very unhealthy (flowers black and shriveled), but the cause is not clear, perhaps a disease. One source of stress on the plants may be related to the decreased flow of spring water over the last two years. Also, one site has been over-run by the invasive species Phragmites australis (common reed) which shades out smaller species.
Mar 14 Small flocks of Red-wings reported widely in the City of Green Bay. Since 1986 the average date for this event on the East River in Allouez is March 10--last year it was Feb 26 (Gary Fewless)
