How to estimate and calculate Animal Unit Months and Animal Unit Equivalents to help manage for sustainable grazing and maintaining federal grazing permits is explained in a new bulletin from the University of Wyoming Extension.
The information is in Animal Unit Month Concepts and Applications for Grazing Rangelands, B-1320. An AUM is the amount of air-dry forage a 1,000-pound cow and her un-weaned calf will consume (the “Animal Unit”) in one month. AUMs are frequently used to determine sustainable stocking rates for grazing pastures and rangelands in the West. AUMs can also be useful for managing private lands grazing because they link animal demand with forage supply.

Farm safety and learning from local niche marketers and vendors are part of the Women’s Ag Expo at the Washakie County Fairgrounds in Worland.
The program is 9 a.m.-2:30 p.m. Wednesday, Aug. 29.
“Women will share their business experiences with other women in ways that provide inspiration, motivation and networking opportunities,” said Lisa Bower with the Farm Service Agency in Washakie County.
There will be live demonstrations on electrical, grain bin and equipment safety.
Caitlin Youngquist, Washakie County University of Wyoming Extension educator, will moderate a panel discussion with local producers about farm and ranch program participation and success stories.
“This will be a fun and educational event for women involved in all forms and sizes of agricultural production,” she said. “Participants will also learn about local niche marketers and vendors who produce and distribute agricultural products.”
Event organizers are seeking vendors of agricultural products and services who would like to participate. There is no cost to have a booth, said Youngquist.
Contact Bower at 307-347-2456, ext. 2, for more information or to register.
Lunch from Chubby Cheeks Barbeque will be available for $12. The Farm Service Agency, the Natural Resources Conservation Service, the Washakie County Conservation District and University of Wyoming Washakie County Extension are hosting the Expo and hope to make this an annual event.
Fearsome cheatgrass taking over land can generate enough horror to reach for silver bullets.
But there are no silver bullets for cheatgrass, University of Wyoming Extension specialist Dan Tekiela told those attending the July 11 cheatgrass management field day in Sybille Canyon.
More than 45 people attended the event in the relatively isolated Tom Thorne/Beth Williams Wildlife Habitat Management Area between Laramie and Wheatland, representing producers, government agencies and the herbicide industry.
Pickups and SUVs parked near the herbicide test plots, the attendees having heard Tekiela earlier discuss management options and the importance of managing the soil seed bank.
They saw results – or lack – of herbicide trials in a heavily cheatgrass infested area for which the Wyoming Game and Fish Department and state lands had treated more than a decade ago.
The cheatgrass shrugged off the earlier treatments and returned, and agency representatives wanted to see what alternatives could eradicate, or at least lessen, the cheatgrass.
Tekiela partnered with them on the project and wasn’t perplexed at the higher-than-thought turnout to the isolated area because cheatgrass isn’t selective – everyone has a problem with it. Researchers across the nation are studying the invasive grass.
“It’s the poster child of invasion in the West,” he said. “People are scrambling for information, but we don’t have the silver bullet.”
There will likely never be a one-size-fits-all solution, but Tekiela had specific takeaway messages during the day.
A ranch tour focused on rangelands and local agriculture is Saturday, Aug. 4, in Teton County.
The event is 10 a.m. to noon and includes a tour at Snake River Ranch, said Glenn Owings, University of Wyoming Extension educator. He said there is no cost to attend, but registration is required. There is a limit of 30.
Presentations are 10-11 a.m. at the Teton County 4-H Extension Office, 255 W. Deloney, in Jackson, and include rangeland ecosystems, how ranches typically work in Wyoming and associated landscape values. The Snake River Ranch tour is 11:15 a.m.-noon.
Owings said there is no age limit, although minors will need to be with an adult.
“The event will go on rain or shine,” said Owings. “Transportation from the classroom to the ranch is not provided. Please carpool if possible.”
Visitors to Cheyenne Frontier Days can build a ranch, change a stream flow, meet Wyoming’s most (un)wanted outlaw weeds, eat a beef stick from UW Cowboy Branded Meats and test their wool grading skills.
The University of Wyoming College of Agriculture and Natural Resources is presenting displays and interactive activities at the Western Experience area of Cheyenne Frontier Days Park, July 21-22 and July 24-28. Hours are 10:30 a.m.-8 p.m. Look for them next to the BLM horses.
July 21 and 22, visitors can explore native grasses, measure soil pH, gain perspective on the state’s rainfall, and learn what it means to be a headwaters state for three major river basins.
July 24 and 25 are beef days. Highlights include beef trivia, build-a-ranch, meet your meat and free giveaways.
July 26, visitors can view plants and insects and try their hand at determining which are friend and foe.
July 27 and 28 are sheep days. Highlights include sheep trivia, “not your grandmother’s wool,” meet your meat and key qualities of different fleeces.
College of Agriculture and Natural Resources students, staff and faculty members will be on hand. Partners for these activities are the Wyoming Beef Council, Wyoming Wool Growers Association and Laramie County Conservation District.
Other organizations offer demonstrations of horsemanship and training, rodeo and other Western experiences.
