||Observation (Click on links for photos)
||Late summer flowers have
taken over. Goldenrods are very conspicuous now in fields. Ragweed
pollen levels are near the peak for Green Bay area--the levels high
by nearly anyone's standards.
(Solidago flexicaulis) in flower, Door Co (Gary Fewless).
||Another prolonged heat
wave continues in the Green Bay area. It has been warmer than
average and quite humid since July 31 with temperatures in the upper
80's and low 90's. Only 0.18 inches of rain fell so far in August
and 0.85 inches in July, which is nearly 2 inches below average for
this period. The grass in lawns has generally stopped growing and
is turning brown if not watered. Some deeper rooted plants such as
Chicory are doing well however.
(Ambrosia artemisiifolia) in flower, Green Bay. It's hard to
pinpoint the exact first day, because these flowers do not have showy
petals. Common Ragweed and Giant Ragweed (Ambrosia trifida)
cause more pollen hayfever than all other plants combined. You may
notice in the next month that many people will be complaining of "summer
colds" that just won't go away. In many cases the cause is actually
hayfever caused by ragweed.
(Aster macrophyllus) in flower, Brown County, Suamico. Canadian
Goldenrod (Solidago canadensis) in flower, UWGB (Gary Fewless).
|Although a few plants have been in flower
previously, Prickly Lettuce (Lactuca serriola) is now
conspicuously in flower in northeastern Wisconsin.
