A beetle from Asia, Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), was identified in July 2002 as the cause of widespread ash (Fraxinus spp.) tree decline and mortality in southeastern Michigan and Windsor, Ontario, Canada. Larval feeding in the tissue between the bark and sapwood disrupts transport of nutrients and water in a tree, eventually causing branches and the entire tree to die. Tens of millions of ash trees in forest, rural, and urban areas have already been killed or are heavily infested by this pest.

This publication is designed to help identify the most common hardwood or deciduous trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. Remember, vegetative characteristics are quite variable; use more than one specimen for comparison.

In 2005, the Iowa NRCS and Iowa DNR agreed to create new groupings of soils and revise the recommendations for tree and shrub species for those soil groups in Iowa. There were several reasons for this revision: there were errors in the previous recommendations; there were new soils identified and mapped; and both agencies wanted a user-friendly system for employees and the public to use.
