Two weed workshops, weed identification and Difference $7,803weed control methods and a weed sprayer calibration clinic wereconducted. Eighty acres of irrigated land were selected for restoration Total Project Cost $12,400based on infestation with problem weeds including “”Carduus nutans””L, “”Cirsium vulgare””, “”Cirsium arvense”” and “”Cardaria draba””.Herbicide spray treatments took place in 2009, and 2010 followed byseeding with “”Festuca ovina”” and “”Dactylis glomerata”” in October Contributors2010. Production of grass hay was 31 and 72 tons before and afterrestoration, respectively. With grass hay in Utah valued at $99/ton in Project Contributors Labor & Equipment Value2010 and $151 in 2011, hay produced on project acres before and afterrestoration was worth $3,069 and $10,872, respectively, an increase of SARE-FRTEP Grant $2,550$7,803.
