Expect earlier 'call of colors' in Iowa

Dry summer will make season shorter, too

Carolyn Goforth will let Mother Nature do her decorating when she gets married Saturday.

“The ceremony will be at Pikes Peak State Park, and the leaves are really starting to look pretty,” the interim executive director of the McGregor-Marquette Chamber of Commerce said Tuesday.

Goforth, whose interest in fall foliage extends beyond her wedding to the enjoyment of the thousands of tourists who flood northeast Iowa each autumn, said she was worried that the 2012 drought would cause the leaves to turn brown and drop off with little if any colorful display.

So too were Department of Natural Resources foresters Bruce Blair and Mark Vitosh before cooler, damper weather in late August and September allayed their concerns.

Blair, the DNR District forester in Elkader, said severe drought can impact leaf size, vigor and physiology and cause some leaves to fall even before they change color.

Vitosh, whose district includes Linn and Johnson counties, said he saw worrisome symptoms before the drought loosened its grip.

Bottomland species like silver maple, river birch and cottonwood were dropping their leaves early, he said.

Now, despite predictions by for-profit forecaster AccuWeather.com that Iowa and other hard-hit drought states “are probably not going to have a good display of fall foliage this year,” Blair and Vitosh are already seeing signs of a colorful fall.

But, like almost every other natural event this year, including the first widespread frost on Sunday morning, fall colors will arrive early, they say.

“I would say it’s about 10 days early,” Blair said.

Interviewed on Sept. 20, Blair said the sumacs and maples in Clayton County “look like they should on Oct. 1.”

“It’s at least a week early,” said Mary Beth Theis, who has an excellent vantage driving the Great River Road from her Balltown home to her job as director of Guttenberg Development and Tourism.

“It might even be two weeks early this year,” said Darla Kelchen, director of the Clayton County Development Group in Elkader.

Whereas peak color usually occurs there in mid-October, the first weekend of the month “could be prime time this year,” Kelchen said.

Vitosh said leaf lookers would be well advised not to bet on the traditional peak weekend. “Be ready and go when it’s pretty,” he said.

Both Blair and Vitosh said hard frosts and windy rainstorms can quickly strip trees of their colorful leaves.

Vitosh said he still worries about the drought’s impact on trees’ long-term health.

Extreme events like this year’s drought stresses trees and makes them more vulnerable to disease and infestation, he said.

“The drought rang their bell. Another dry year could be fatal,” he said.

If next year is anywhere near as dry as this one, “you would see some big trees dying,” Blair said.

Dendrochronologists examining the rings of tree trunks a hundred years from now should have no difficulty spotting this year’s slim growth ring, he said.
