Use wire fencing to exclude large native herbivores
A replicated, controlled study in 1997 in eucalypt woodlands in New South Wales, Australia (Grant & MacGregor 2001) found no effect of excluding large herbivores on topsoil seed density. The density of topsoil seeds was similar between grazed and ungrazed plots (12,360 and 9,351 seeds/m2 respectively). Topsoil (0-10 cm depth) seeds were monitored in five grazed (1-2 dry sheep equivalents/ha/year) and five ungrazed 20 ×20 m plots. Soil was sampled in 1997 using a soil corer 20 cm in diameter.
