Grasses are the foremost plant family of prairies, savannas, barrens, many agricultural landscapes, lawns, and successional habitats throughout Wisconsin, yet they are notoriously difficult to identify. This field guide to 232 species of Wisconsin grasses includes more than 1,100 illustrations. Setting a new standard as the first new, illustrated midwestern grass identification manual to appear since the 1960s, it provides up-to-date, comprehensive information for naturalists, gardeners, landscapers, nursery horticulturalists, community restoration professionals, agronomists and biologists, and any outdoors lover.

The book includes:

• species descriptions and distribution maps for all 232 species

• more than 700 color photographs accompanying species descriptions
• drawings of most species
• chapters on grass morphology and grasses in natural communities
• keys to all species, including an illustrated key to genera
• a glossary of grass terminology.

At the time of European settlement, tallgrass prairie was the iconic landscape in much of the Upper Midwest. Although its extent has been drastically reduced, intact prairie remnants exist, prairie species persist along roadsides, and interest in prairie reconstruction has increased. The basic prairie matrix is formed by grasses, yet their diversity and beauty are often underappreciated because their flowering structures are highly reduced to aid in wind pollination. This much-needed addition to Iowa’s popular series of laminated guides—the twenty-sixth in the series—illustrates fifty-five grass species characteristic of or commonly found on prairies of the Upper Midwest states of Illinois, Iowa, Indiana, Michigan, Minnesota, Ohio, and Wisconsin.

The authors have organized species into groups by their most easily noted field characteristics. Are the flowering heads branched or unbranched? Are the branches dense, narrow, or fingerlike? For each species, its native or exotic status is followed by the months of flowering, abundance, general habitat, height, diagnostic features, geographic range, and, if relevant, threatened or endangered status.

Even amateur naturalists can identify big and little bluestem and prairie dropseed in the field, but both professional and amateur naturalists find certain grasses harder to identify, especially the less common or rare species such as cluster fescue and sand reedgrass. The photographs and descriptions in Grasses in Your Pocket will be an invaluable reference for outdoor expeditions in midwestern grasslands.
