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.

fog Overcast with fog and light rain early this morning, but mild as the temperature fell only to 52° F.
Oct 29
shagbark hickory There is also a considerable difference in leaf condition within a single species, as for shagbark hickory (Carya ovata). The plant shown at left is growing out in the open by itself and is completely free of leaves.
shagbark hickory This tree, also of shagbark hickory, is growing in a forest and the leaves are mostly still on. Presumably, the surrounding forest helps keep the air a little warmer and may also diminish winds that could blow leaves off. Whatever the cause, there is a big difference in appearance.
Oct 28
  The daily low temperature was 24° F, the lowest of the season to date. Usually our daily low temperature happens early in the morning, but this one was late at night--around 11 p.m., I think.
white ash There is a wide range of leaf condition in local trees. Some, like this white ash (Fraxinus americana) are mostly leaf free (though the fruits remain here).
buckthorn Others, like this invasive alien, European buckthorn (Rhamnus cathartica) are still fully green and functional.
Oct 25

Another heavy frost this morning. We've been through a period of several consecutive days of cold nights and cool days so the cooling surface soil allows for the frost to stay longer in the morning. The plant is yellow coneflower (Ratibida pinnata).

Our morning low temperature was 26° F, the lowest of the season so far.

Oct 22
  The morning low temperature was 31° F in Green Bay.
deer There was a deer along the roadside this morning, very brave and not leaving even when I stopped nearby for photos. That kind of indifference to threat often indicates illness or injury.
shoreline Green Bay shoreline at UWGB.
pumpkin There is a pumpkin plant growing along the beach on Green Bay, tangled up in marsh plants and zebra mussel shells, and still flowering until this morning. Given the large number of opportunities, even plants that don't normally "escape" from gardens will ocasionally show up in odd places.
Oct 21 There was at least a trace of snow north of about U.S. Highway 8 (i.e. about 80 miles north of Green Bay) and widespread frost throughout. Some locations (e.g. Lac Vieux Desert) received up to 1.5 inches of snow.
Oct 20 Morning low temperature of 31° F in Green Bay and more substantial frost this morning. This is the first time the temperature fell to or below 32 since May 13 (159 days) and before that single day day of freeze it goes back to April 24.
Oct 19 Morning low temperature of 33° F in Green Bay, and light frost early in the morning. Lowest temperature of the season to date.
Oct 18
stiff goldenrod Some plants remain easily recognizable long after they are done for the season, as this stiff goldenrod (Solidago rigida) on UW-Green Bay's prairie.
Oct 15
leaves There has been an abrupt dropping of leaves by cottonwoods (Populus deltoides) on the UW-Green Bay campus.
Oct 14
uw-Green Bay

Still plenty of leaf color in the Green Bay area.


Frost and freeze in northeastern Wisconsin this morning:
Rhinelander 28° F
Florence 29°
Eagle River 30°
Laona 31°
City of Green Bay fell to 34° F.
City of Marinette, on the shore of Green Bay, fell only to 37°.

fog More fog this morning, here on UW-Green Bay's Cofrin Arboretum.

UWGB and beyond Here's a view looking across UW-Green Bay and the Bay, to the Leo Frigo Bridge on Highway I-43 on the left and the Pulliam electrical power generation plant at the mouth of the Fox River on the right.
Oct 8
green bay shore There are still many leaves on the trees in some locations, as here near the Green Bay shore at UW-Green Bay.
Oct 7
sandhill crane There were 2 Sandhill Cranes near the soccer fields on UW-Green Bay this morning.
Oct 6 Monarch butterfly flying on the Fox River Trail, Allouez, Brown County, WI (Mike Draney).

Point su Sauble Point au Sauble from the UW-Green Bay shore. Most trees are remarkably green for this date.
Oct 1
staghorn sumac Staghorn sumac (Rhus typhina) is at about peak fall color on plants in the open at UWGB and will decline rapidly hereafter. Plants that are at the edges of woods are somewhat protected and are not so far along.
