Forage and Pasture Educational Program for Extension, FSA, and NRCS in the Pacific Northwest
The production of a Pasture and Grazing Management Guide was completed in 2009 and printed books will be available in early 2010.
The objectives of the third phase of this project were to produce a pasture monitoring form and guide; and publication of an intensive pasture and grazing management guide. PASTURE AND GRAZING MANAGEMENT IN THE NORTHWEST is a Pacific Northwest Extension Publication PNW 614. There are an introduction, 17 chapters, and a glossary by 36 authors from Cooperative Extension, USDA Agricultural Research Service and Natural Resources Conservation Service, and a private consultant. Authors are located in the states of Washington, Oregon, Idaho, Montana, Utah, and West Virginia. The 208 page document edited by Glenn E. Shewmaker and Mylen G. Bohle is published by the University of Idaho Extension. This is the first comprehensive management guide for pastures and grazing in the Northwest.

Proofs were approved on December 18, 2009 and the book is in the process of being printed, thus the copyright date of 2010. Below are the contents of the guide book.

Color plates follow page 204
Three spreadsheets were developed to assist producers, extension, and advisors. The Pasture ruler calibrations.xls and Idaho RPM calibration.xls spreadsheets assist in calibrating the pasture stick, rising plate meter, and falling plate meter. The Grazing wedge.xls spreadsheet allows forage biomass records to be kept and is easily used to create a grazing wedge, which graphically displays the amounts of available forage at any one time. These are down-loadable from the following web site: http://www.extension.uidaho.edu/forage/
Summarization of pasture data has progressed with publication of the following abstract:
Hooper, Laura, G.E. Shewmaker, and T.C. Griggs. 2008. Relationship of sward height and herbage mass for orchardgrass (Dactylis glomerata L.), smooth bromegrass (Bromus inermis Leyss.), and perennial ryegrass (Lolium perenne L.) in a pasture system. Abstract, 61st Annual Meeting Society for Range Management, 27-31 January 2008, Louisville, KY.
More complete summarization of forage prediction data was completed in a Master of Science Thesis by Laura Hooper in May 2007, University of Idaho.
Shewmaker,G.E., L.K. Hooper, and T.C. Griggs. 2010 (in press). Predicting herbage mass in irrigated orchardgrass. In Proceedings IV National Conference on Grazinglands, 13-15 December 2009, Sparks, NV; Grazing Lands Conservation Initiative.
Impacts and Contributions/Outcomes
The pasture monitoring form and guide; and the PASTURE AND GRAZING MANAGEMENT IN THE NORTHWEST book should serve as good resources for Cooperative Extension, USDA and Natural Resources Conservation Service, crop advisors and producers. We expect extensive use in the states of Washington, Oregon, Idaho, Montana, and Utah. This is the first comprehensive management guide for pastures and grazing in the Northwest.
