| In
spite of the death toll on native species, federal and state land
agencies continue to promote and protect livestock grazing on public
lands in the West. Livestock ranching on federal public lands is subsidized
to the tune of $100 million annually in direct payments; indirect
subsidies may be three times that. Taxpayers are footing the bill
for ranchers to run livestock on 270 million acres of federal public
land in the 11 western states-an area that represents fully one third
of these states' total land area |

Range fencing detrimentally affects wildllife. Here we see a dead Long eared owl entangled in barbed-wire. Owls are nocturnal hunters that cannot see the invisible fencing at night.

Appelton Whittell preserve, SE Arizona. The work on Appleton Whittell contrasted a 30+ year cow free area with adjacent grazed areas in which researchers report that grasses in winter on the AW were taller (4.4-fold) and had higher basal area ground cover (2.5-fold), canopy cover (2.2-fold), and reproductive canopy cover (10-fold) than in the grazed area after a drought. 19 species of ground-foraging, seed-eating birds (e.g., doves, quail, sparrows, towhees) were 2.7 times more abundant. Significant differences persisted even after a year of reduced stocking in response to drought on the grazed areas. Bock & Bock, (1993) also found that grass canopy cover was greatest on the ungrazed AW than on adjacent grazed sites. The tallest species showed the greatest height recovery increases in ungrazed plots.
