Recognizing the importance of a clear consensus of terms and their definitions used in grazing lands, The Forage and Grazing Lands Terminology Committee was formed in 1989 through the American Forage and Grassland Council. Terminology for Grazing Lands and Grazing Animals, published in 1991, addressed 106 terms. Results were reported at the XVII International Grassland Congress in 1993. At the Congress’s request, and in collaboration with the International Rangeland Congress, this was expanded to include an international scope that resulted in the terminology we have today. An International Terminology for Grazing Lands and Grazing Animals was published in 2011 and translated into seven languages.
