administration down to the Gardner
River at the first bridge, and back up

Overgrazing is very prominent.
Every shrub and pitchin has a "high-

Hardly a twig remains below the
line. Sagebrush is browsed until
it is stubby, and many bushes are
killed. Grass is cropped to the
very ground. The Giant Rye grass
is quite prevalent. Even it has

are severely barked along the
pronounced high water line, and
have no reproduction. The hills
look bare and are covered with
game trails. Chrysothamnus & choke-
cherry & snowberry have been heavily
browsed - only a few stubs
remaining in many clumps.
Erosion is setting in. Bankspur
is showing in scattered places.
If there are 10,000 elk in this
northern herd, it is my opinion
that they should be reduced to 5,000.
The range looks as bad as the Kiahah,
