Abstract
Fecal seedingby livestock may be an effective, low-cost means
of rangeland restoration. We compared recruitment of switch-
grass(Panicum virgatum L.) from seedfed to cattle and deposited
in dung to that of broadcast-seededplots receiving a comparable
number of unfed seed. Although germinability of seed passed
through livestock (52 to 62%) was reduced relative to that of
broadcast seed(85to 91%), recruitment of switchgrassfrom seed
in cattle feceswas equal to or superior to that of broadcast seed
in terms of establishment (frequency of occurrence and density),
plant growth and final plant sire. The frequency of plots with
emerging switchgrassplants ranged from 62to 100% when seeds
were delivered in feces, but only 2 to 40% when seeds were
