Des Moines Register: Iowa lost an estimated 7.2 million trees in cities and farms when last year’s hurricane-force derecho swept across the state, a new Iowa Department of Natural Resources report shows. Cedar Rapids, Des Moines and Davenport suffered the largest tree losses in the Aug. 10, 2020, storm, according to the DNR report, as winds surged up to 140 mph in some counties. Overall, Iowa cities lost about 4.5 million trees, or 13% of the state’s 34 million urban trees, the report says. The storm damaged an estimated 32,773 acres of urban tree canopy. Iowa’s rural lands lost 2.7 million trees, the state reported.
