Restoration of grasslands dominated by tall fescue (Schedonorus phoenix [Scop.] Holub) to native tallgrass prairie usually requires burning, herbicides, or reseeding. We tested seasonal grazing by livestock in winter, combined with cessation of fertilization, as a restoration tool for modifying the competitive dynamics among herbaceous plants to restore tallgrass prairie communities in southeastern Kansas. In 2004-2005, we compared responses of grassland plants and birds across a chronosequence of pastures that were winter-grazed from 1 yr to 5 yr. We compared winter-grazed pastures to pastures grazed year-round and to local native prairie remnants as starting and endpoints for restoration, respectively. Abundance of native warmseason grasses increased from 2% to 3% mean relative frequency in pastures grazed year-round to 18% to 30% in winter-grazed pastures, and increased with duration of winter-grazing. Native warm-season grasses accounted for 1-6% of total live aboveground biomass in pastures grazed year-round, 1-34% in winter-grazed pastures, and 31-34% in native prairie remnants. Tall fescue abundance and biomass were similar among grazing treatments, with a trend for tall fescue to be less dominant in winter-grazed pastures. Tall fescue made up 9-40% of total aboveground biomass in year-round grazed pastures and 10-25% in winter-grazed pastures. Grassland birds showed variable responses to winter-grazing. Dickcissels (Spiza americana) and Henslow's sparrows (Ammodramus henslowii) were more abundant in winter-grazed pastures, whereas eastern meadowlarks (Sturnella magna) and grasshopper sparrows (A. savannarum) had similar abundance in pastures grazed year-round and during winter. Winter-grazing of pastures dominated by tall fescue combined with suspension of nitrogen fertilization could be an effective restoration technique that allows use of prairie rangeland while improving habitat for sensitive grassland birds. Resumen La rehabilitación de los pastizales dominados por festuca alta (Schedonorus phoenix [Scop.] Holub) a pastizales nativos generalmente requiere el uso de fuego, herbicidas, o resiembras. Utilizamos el pastoreo estacional con ganado durante el invierno, combinado con el cese de fertilización como una herramienta rotacional de rehabilitación para modificar la dinámica competitiva entre plantas herbáceas y con esto rehabilitar las comunidades de pastizales de pastos altos en el sudeste de Kansas. En 2004-2005, se compararon las respuestas de las plantas en estos pastizales y las aves a trave´s de una cronosecuencia de los potreros que se pastorearon durante el invierno de uno a cinco añ os. Comparamos los potreros que se pastorearon durante el invierno a los que se pastorearon todo el añ o, con los remanentes de la vegetación nativa del pastizal como punto inicial y final para la rehabilitación respectivamente. La abundancia de pastos nativos de crecimiento de verano aumentó de un 2-3% de la media de la frecuencia relativa en los potreros pastoreados todo el añ o, a 18-30% de los potreros pasto...
