LINCOLN — Nebraska’s state tree, the cottonwood, may struggle to thrive in the Cornhusker State.
University of Nebraska-Lincoln Extension forester Dennis Adams said the cottonwood is threatened by several factors.
It needs bare mineral soil to regenerate, which is common after flooding. But Adams said modern flood control efforts make it harder for the trees to reproduce.
Adams said cottonwoods can also be damaged by livestock grazing and by herbicides used in nearby farm fields.
