The North Dakota Game and Fish Department’s annual bighorn sheep survey revealed a minimum of 293 bighorn sheep in western North Dakota, virtually unchanged from the previous count of 297. In total, biologists counted 85 rams, 159 ewes and 49 lambs. Not included are 24 bighorn sheep introduced from Alberta in February, and approximately 30 bighorns in the North Unit of Theodore Roosevelt National Park. Big game biologist Brett Wiedmann said the count in the northern badlands was the highest on record, beating the previous record set in 2012, but the southern badlands population declined 15 percent. “Rams and lambs showed a slight decline, but adult ewes increased,” Wiedmann said. “About 75 percent of lambs counted during last summer’s survey survived the winter, which is about average, but the recruitment rate of 37 percent was above average.” Game and Fish Department biologists count and classify all bighorn sheep in late summer, and then recount lambs the followi...

(Photo credit: Wikipedia) The North Dakota Game and Fish Department’s annual bighorn sheep survey revealed a minimum of 297 bighorn sheep in western North Dakota. The 2012 count was second highest on record and 5 percent above last year’s survey. In total, biologists counted 87 rams, 156 ewes and a record 54 lambs. Not included are approximately 30 bighorn sheep in the North Unit of Theodore Roosevelt National Park. Big game biologist Brett Wiedmann said the northern badlands population was the highest on record, but the southern badlands herds declined slightly. “Although adult rams and ewes were virtually unchanged from 2011, we were very pleased to see a record number of lambs recruited into the population, as well as a record recruitment rate of 38 percent,” Wiedmann said. “Nearly all of the lambs we counted during last summer’s survey survived the winter.” Game and Fish Department biologists count and classify all bighorn sheep in late summer and then recount lambs the followi...
