Several thousand Tundra Swans are now scattered along the
west bayshore of Green Bay from at least Oconto southward, Oconto
County, Pensaukee area (Tom Erdman).
Woodcock and Saw-whet Owls were calling at

The ice went off prairie
pond today on UWGB's Cofrin Arboretum. It had nearly melted
off in the warm period of about March 10-14, but colder weather
returned and established firm ice again.

||The first flowers of Acer saccharinum
maple) began dispersing pollen today in the city of Green
Bay. This same tree has an average first flower date of March 25 over
the last 21 years and the date has been exactly March 25th 3 of the
last 4 years. You may be tempted to conclude from this data set that
March 25th is the "normal" date for first flower, however
the date has ranged from March 6 through April 5 during this period
(31 days). In fact most items of phenology have ranged over 4 or 5
weeks during the period of this study.
||There was a light covering of snow this morning
in Green Bay. The airport reported 0.1 inch, but it was enough to
whiten streets and driveways. Temperatures rose into the mid-30's
and the snow quickly melted.
The earliest plants of Symplocarpus foetidus (skunk cabbage)
began to flower (pollen released) today, City of Green Bay. These
early plants are in springs where the flowing water prevents the
soil from freezing. Other plants, not in springs, may not flower
for 2 or 3 weeks more. As I have mentioned in the past, the populations
of skunk cabbage have declined significantly in all the places in
which I regularly see them. This may be in large part because the
ground water seems to be depleted in the springy areas. Springs
that I have visited each year for over 20 years are at the lowest
flow during that period--including the serious drought years of
1987 and 1988. The skunk cabbage plants also seem to be affected
by a disease in recent years.
Although the ice went out on the East River on March 13th, a thin
shell of ice re-formed overnight (March18/19). Ordinarily, ice would
not have formed because of the flowing water of the river, but most
melt water has already passed through the system and we have had
virtually no precipitation in the last 12 days so there is no perceivable
flow in the river in its lower reaches. The ice quickly melted as
the temperature rose later in the morning.
||I have received several reports of returning
Robins, but this is the first day that I saw flocks of Robins
in the fields near our house.
||Although a major winter storm was forecast
for today with 6 to 8 inches of snow for the Green Bay area, we received

Although the temperatures remained in the 30's this morning, it
was sunny and the birds were quite vocal: Red-winged Blackbirds,

There have been no flowering plants yet, but many species have
begun to grow, including mosses
and liverworts on raised surfaces such as fallen trees,
stumps, etc. Also the new leaves of some overwintering plants are
clearly emerging. One example is the common yard plant Matricaria

||After several cloudy and foggy days in Green
Bay we experienced a bit of sunny weather today and mild temperatures
continue. The temperature has not fallen below freezing since the
morning of March 7th and melting snow has now produced puddles and
