“…Tillers are grazed in direct proportion to their pre-defoliation tiller heights. This agrees with other findings on frequency and intensity of tiller defoliation (Morris 1969, Briske and Stuth 1982, Hart and Balla 1982, Clark et al 1984. About 20-30% of the pre-defoliation tiller height is observed to be removed per defoliation event by sheep or cattle (Heitschmidt et al 1990).…”

“…Hodgson (1966), Hodgson and Ollerenshaw (1969), Allison and Kothmann (1979), Briske and Stuth (1982), and Curll and Wilkins (1982) all confirm that high stocking rates increase efficiency of defoliation. Brown and Stuth (1984) suggest it is possible to modify patterns and degree of utilization by altering stocking rate.…”

“…Clipping little bluestem after apical meristems have been elevated stimulates tillering the first year (Jameson and Huss 1959 (Mullahey et al 1990). This change in the size of plants and plant parts commonly occurs in response to heavy grazing (Hanson et al 1931, Holscher 1945, Weaver and Darland 1947 (Hodgson 1966, Morris 1969, Briske and Stuth 1982, Curll and Wilkins 1982, Hart and Balla 1982, Jensen et al 1990; 2) the relative relationship between defoliation frequency and intensity (Cassady 1953, Owensby et al 1974, Buwai and Trlica 1977, Gammon and Roberts 1978c, Clark et al 1984, Mullahey et al 1990); and 3) the importance of tiller architecture i.e., height, total lamina length and location in the canopy, in determining defoliation probabilities (Greenwood and Arnold 1968, Hodgson and Ollerenshaw 1969, Bartham and Grant 1984, Pierson and Scarnecchia 1987, Heitschmidt et al 1990). …”

“…However, responses of Old World bluestems to defoliation have been studied with clipping (e.g., Anderson andMatches 1983, Coyne andBradford 1985) rather than grazing. Hodgkinson (1980) and Briske and Stuth (1982) have indicated that grazing patterns are seldom adequately characterized, and such information is necessary if grazing is to be simulated. Because grazing patterns are difficult to reproduce, Hodgkinson (1980) concluded that future studies should examine physiological stress in plants subject to actual grazing and growing in natural communities.…”

Rest–grazing before soil thawing alters the below‐ground distribution and extent of rooting in Carex subalpine meadows

Livestock activities impact plant rhizomes and roots in the topsoil, particularly in the early stages of spring for a Carex subalpine meadow. Rest–grazing during critical periods can prevent harm to these roots and rhizomes caused by livestock, thereby enhancing the ecological performance of grasslands. In accordance with soil thawing and plant re‐greening, we designated five rest–grazing periods during the spring in a Carex subalpine meadows. The findings demonstrate that the topsoil of 0–10 cm, largely consisting of Carex roots, housed over 70% of root volume and root mass. After the plant had regained its greenery for a certain duration, rest–grazing resulted in higher vertical root length distribution index. With earlier rest–grazing, root growth in deeper soil was promoted, consequently transporting more organic material to the deeper soil. Deferred rest–grazing time has the potential to enhance lateral rooting extent, root resistance to vertical uprooting, and root accumulation in topsoil. It follows that increased root accumulation in the topsoil leads to greater loss of soil nutrients and carbon. Consequently, we recommend rest–grazing prior to soil thawing for Carex subalpine meadows, which encourages Carex root growth and fosters greater biomass accumulation in deeper soils. Avoiding “running for the green” and “trampling tillage” has a positive effect on both productivity and long‐term soil nutrients and carbon pool management in pastures.
