Iowa's Changing Wildlife : Three Decades of Gain and Loss

Much has changed with Iowa’s wildlife in the years 1990 to 2020.

Some species such as Canada goose, wild turkey, and white-tailed deer that once were rare in Iowa are now common, and others like sandhill crane, river otter, and trumpeter swan are becoming increasingly abundant.

Iowa’s Changing Wildlife provides an up-to-date, scientifically based summary of changes in the distribution, status, conservation needs, and future prospects of about sixty species of Iowa’s birds and mammals whose populations have increased or decreased in the past three decades.

Readers will learn more about familiar species, become acquainted with the status of less familiar species, and find out how many of the species around them have fared during this era of transformation.
