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.

July 2007

July 31

The bright yellow flowers of Solidago canadensis (Canada goldenrod) are beginning to appear in local fields, although only a small percentage of plants are in flower.

The temperature is 90° F at 5 pm [the daily high temperature was 91°] .

The total precipitation for the month was 2.41 inches, which is about 1.03 inches (30%) below average. We received a total of only 0.09 inches of rain over the last 19 days of the month.

July 30 Green Bay reached a high temperature of 90° F today after 89° yesterday. The next few days are also forecast to be in the 90's and humid. Still no significant rain (although some nearby communities have had rain).
July 26 Green Bay has been dry lately with only sprinkles of rain since July 12. There were substantial thunderstorms in northern Wisconsin today, but they were spotty and the Green Bay weather station reports only 0.05 inches of rain. Rhinelander received 1.65 inches of rain. The humid air of the last couple of days is predicted to depart today.
July 23 Another invasive plant has been found in northeastern Wisconsin. Vincetoxicum nigrum (black swallow-wort or dog-stangling vine) has been found in the Baileys Harbor area of Door County by Karen Newbern of the Ridges Sanctuary. It was previously known in Wisconsin only in the southernmost two tiers of counties (i.e not north of Milwaukee).
July 20 Another new invasive plant has been reported from northeastern Wisconsin. Hydrilla verticillata (Hydrilla) was found in Marinette County. Follow the link for photos and a description. This is the first record of this species for Wisconsin.
July 18 Several small but very strong thunder storms moved through northeastern Wisconsin this afternoon, including one that passed through the Bay Beach Wildlife Sanctuary area of Green Bay. Downed power lines left some Green Bay homes without electricity and East Shore Drive between Danz Avenue and Webster Avenue was still closed to traffic the next morning as crews cleaned up fallen trees.
July 17 Returning after an absence of 10 days, numerous species have recently begun to flower on the UWGB campus, including Silphium terabinthinaceum (prairie dock), Mimulus ringens (monkey flower) and Solidago gigantea (giant goldenrod).
July 05 A new invasive species for Wisconsin has been discovered in Brown County. Please send a note if you find this plant elsewhere.
July 01

Returning after a few days away, there are Silphium laciniatum (compass plant), Daucus carota (wild carrot) and Sonchus arvensis (sow thistle) new in flower, UW-Green Bay..
