The College of Agriculture at Montana State University and High Country Apps have partnered to produce the new Montana Grasses identification app for iOS and Android devices. The app provides images, species descriptions, range maps, flowering period, and technical descriptions for over 280 grasses and grass-like plants (graminoids) inhabiting Montana and adjacent areas of Wyoming, North Dakota, and Idaho. The majority of species included are native, but introduced species common to the region are covered as well. The app does not need an Internet connection to run, so you can use it no matter how remote your wanderings take you. The number of species covered and wealth of information included sets a new standard for grass identification apps. Though primarily designed for amateur enthusiasts, the breadth of content in Montana Grasses also makes it appealing to more experienced botanists. Users can browse the species list by common or scientific name to locate a plant and access the related information. However, most users will want to rely on the easy-to-use search key to accurately identify plants of interest.
