Revegetation on rangelands in the Intermountain west is conducted with long-term goals in mind. However, many trials only look at short-term data. The purpose of this study was to revisit plots that were originally seeded with cool-season grasses and forage kochia to suppress broom snakeweed and downy brome. Grasses were seeded in October 2003 and forage kochia in March 2004. The seeding treatments comprised of three introduced grasses, three native grasses, an introduced grass mix, a native grass mix, and forage kochia. The treatments were seeded into 3 by 15-m plots at Howell and Nephi, Utah within the sagebrush-steppe biome. Frequency and biomass measurements were taken in 2015 to determine long-term persistence and forage production. At the Howell location, crested wheatgrass, pubescent wheatgrass, and western wheatgrass all persisted (? 75%) and produced 1,520 � 168, 2,160 � 168, and 1,760 � 168 kg/ha of forage, respectively. Russian wildrye and big squirreltail were still present at 35 and 20 %, respectively. Bluebunch wheatgrass and forage kochia did not persist (< 2%). At the Nephi location, crested wheatgrass, pubescent wheatgrass, and western wheatgrass all persisted (? 62%) and produced 3,760 � 552, 3,200 � 552, and 2,240 � 552 kg/ha of forage, respectively. There was very little Russian wildrye and big squirreltail remaining (? 13%) and no bluebunch wheatgrass remaining (1%). Forage kochia was still present at the Nephi site (41%). Our results suggest that crested wheatgrass, pubescent wheatgrass, and western wheatgrass can be used to rehabilitate disturbed landscapes due to their ability to establish and persist longer than 10 years.
