||Observation (Click on links for photos)
||Very warm in Green Bay, with
a high temperature of 83 F.
||There is still very little
fall color in Northeastern Wisconsin. The Sugar
Maple forests are still mostly green, as seen in this photo
from Florence County. Some Staghorn
Sumac (Rhus typhina) and Red Maple (Acer
rubrum) leaves have turned red. Black Ash (Fraxinus
nigra) leaves have turned brown in many places and some herbaceous
plants like Bracken Fern (Pteridium aquilinum) and Wild
Sarsparilla (Aralia nudicaulis) have turned brown and yellow
respectively. It is likely that the period of fall colors will be
shorter this year than usual (Gary Fewless).
The low temperature this
morning was 35F at the airport and there were scattered reports
of frost across the area. That is the lowest temperature
in Green Bay since May 21.
Ash (Fraxinus pennsylvanica) leaves have begun to
quickly turn yellow, which is their typical Fall color. Sumac is
also well along in color change.
Sumacs (Rhus typhina) now beginning
to turn red, UWGB (Gary Fewless).
||Light frost in low-lying
areas of northeastern Marinette County and elsewhere in northeastern
Wisconsin. There is still very little evidence of fall leaf color
although some leaves have dried up and turned brown. There are some
Red Maple (Acer rubrum) leaves turning red, and some
Staghorn Sumacs (Rhus typhina) (Gary Fewless).
(Laetiporus sulfureus) and Beefsteak (Fistulina hepatica)
mushrooms observed, near Holland, Brown County (Matt Welter).
Creeper (Parthenocissus vitacea)
are quickly turning red, UWGB (Gary Fewless).
Canada Geese have returned to the East River
and adjacent marshes and fields in large numbers.
(Solidago speciosa) first open flowers, UWGB (Gary Fewless).
This species begins to flower later than any other of which I am
aware, in the Green Bay area. It began to flower as the leaves of
Sumac in the same field began to turn red. There are still only
a few plants of New England Aster (Aster novae-angliae)in
flower on UWGB.
The first plant to flower last spring was Skunk
cabbage on March 12, 183 days ago, or about 6 months.
Canada Goldenrod is at about peak of yellow
color in UWGB fields, but the Asters are all still very inconspicuous.
Ladies-tresses (Spiranthes cernua)
in flower along roadside on county highway Y, Town of Peshtigo,
Marinette County (Joel Trick). [This species may have been in flower
since late August, but had not previously been reported here, GF]
Giant Puffball mushrooms observed on UWGB
Still very little leaf color change in Oconto and
southern Forest Counties. Except for injured or diseased individuals
the only conspicuous color was from some red leaves of Sumac
(Rhus typhina) and the yellow leaves of Common Milkweed
(Asclepias syriaca) and Spreading Dogbane (Apocynum
androsaeifolium). Some Black Ash (Fraxinus nigra)
leaves have begun to curl up and turn brown at the edges, but not
to turn yellow.
||Flying Ant day.
Millions of flying ants emerging and flying all over Green Bay and
DePere. Gulls are swarming and flying erratically while eating
them. This event always happens an "off" day in September
when it is unusually warm and muggy, rather than cool. Ants seen swarming
in the grass, on sidewalks and climbing tall things (Betsy Bartelt
and Matt Welter).
England Aster (Aster novae-angliae)
first fully open flowers, UWGB. (Gary Fewless).
Over 1000 Chimney Swifts swirling around
a single chimney
near sunset. Like a bat emergence in reverse, the chimney swifts
enter the chimney within fifteen minutes. By 7:45 pm they have all
fluttered down into the chimney. St. Norbert Campus, West De Pere
(Rhus typhina) leaves are turning red in northern Wisconsin.
In the Townsend area of Oconto County the leaves of some clones
are about half turned to red and some conspicuous color is evident
all the way south to Brown County (but less so near the Bay). Virginia
Creeper (Parthenocissus inserta) is also rapidly
changing color. Most other trees and shrubs are still green however,
except for damaged or diseased individuals (Gary Fewless).
Zig-zag Goldenrod (Solidago
flexicaulis) in flower, T. of Cooperstown, Manitowoc Co., (Joel
An unseasonally warm day in northeastern
Wisconsin, some areas near 90F with high humidity. Ragweed pollen
remains high, causing numerous people to suffer from hayfever, often
misinterpreted as "a summer cold".
(Aster ericoides) first fully open flowers, UWGB (Gary Fewless).
||Several conspicuous species
have not yet begun to flower on UWGB, including the large blue-flowered
New England Aster (Aster novae-angliae), Heath Aster
(Aster ericoides), and Showy Goldendrod (Solidago
speciosa) (Gary Fewless). They won't have long to produce mature
seeds before the growing season ends. As you might imagine, these
species are near the northern edge of their distribution here.
||First flowering of Jerusalem
Artichoke (Helianthus tuberosus), UWGB (Gary Fewless).
First flowering of Maximilian's
sunflower (Helianthus maximilianii), Baird Creek
area, City of Green Bay (Gary Fewless). Calico Aster (Aster
lateriflorus) has only been in flower for a couple of days (I
missed the start).
