Fall colors starting in northern Wis.

Wisconsin’s fall color show is beginning in northern regions of the state and forestry specialists expect this year’s red, yellow and russet hues to be spectacular.

The state Department of Natural Resources says weather during the growing season is essential for the quality of leaves that provide the stunning color. DNR forestry sciences section chief Carmen Hardin says the growing season has been excellent across much of Wisconsin. Hardin says the shortened day length is the primary trigger for trees to begin changing color.

The DNR says peak fall color usually occurs in far northern Wisconsin during the last week of September and the first week of October. Significant color can appear earlier in isolated, lower lying areas by mid-September.
