The number of red and white oak trees in Iowa has dropped in half over the last 35 years, according to data from the United States Forest Service. Iowa DNR forester Mark Vitosh says there are several things that could be impacting the oaks.
Vitosh says another question is where are the replacements when the older trees die out.
But Vitosh says another big challenge is a shift in many of Iowa’s forests. He says part of the problem is without wildfires and other disturbances, shade-tolerant trees like sugar maple and hackberry fill in the open areas and that makes it difficult for young oak trees to grow. He encourages landowners to work with professional foresters to support the future of oak forests in Iowa.
Vitosh says professional foresters can help landowners develop long-term management plans that benefit the future of oak forests. Vitosh made his comments on the Iowa Public Radio program “Talk of Iowa.”
