sheep

Several weeks ago I wrote about my most memorable wildlife encounters. Inexplicably, I failed to mention what was probably the most unusual of them all: the sighting of two bighorn sheep as I was hiking down the south side of Pinchot Pass. The encounter was doubly unlikely. First, hikers don’t often get this close to one (or, in this case, two), and second, even if you are close to them, they blend in so well to the terrain that they are extremely easy to miss.

Watching this ewe and ram negotiate the rocky, uneven terrain with more grace than I can summon walking across the dance floor was a humbling experience.

This may be the closest I’ve ever been to an endangered species. They came close to disappearing entirely.

There were many factors that contributed to the shrinking size of the herd. The most cited include hunting (which, obviously, is no longer permitted), competition from domestic sheep, and disease. They are also a favorite dinner for cougars. In the mid-1990s there were only about 100 animals left; nevertheless, it took nearly five years for the Sierra Nevada Bighorn Sheep to be added the endangered species list. Three separate geographic recovery units were created in the north, central, and southern parts of the Sierra Nevada. The John Muir Trail passes through all three of them.

Since then there has been a carefully managed program to revitalize the herd. In 2013 it was estimated to exceed 500 animals. That may not sound like many, but it’s likely that the herd was never all that large. The California Department of Fish & Wildlife estimate that prior to contact with the west, it was “more than 1,000” strong.

If you see these amazing animals in the wild you are in for a treat. They somehow manage to move across impossibly rugged ground with as little apparent effort as a lazy bear strolling through Cook’s Meadow. I’ve spoken to hikers far more experienced than I who have never seen one. Seeing these two made for a pretty great morning.

Good hiking, Ray

If the sheep hadn’t been chased out of the Sierra, the meadows would not look this this.

Recently, there has been a lot of news, from Nevada, about grazing rights on public property. As I read about the conflict I was immediately reminded of the Sierra Nevada, the late 1800s, and sheep.

Sheep ranching has a long history in the state of California. In 1880, there were in excess of four million of what John Muir would call “hoofed locusts”, more than in any other state in the union. Many of the original shepherds had come from Spain, where the custom was to use the lowlands in the winter for grazing, and then the high mountain meadows when the weather turned warmer. If such a technique worked in Europe, why not the Sierra?

It turned out that there were lots of problems with that approach, mostly stemming from two fundamental conditions: there were too many sheep and there were few controls over who could graze where. (What controls that did exist were unenforceable). This lack of policy meant that whomever got to the meadows first got to do the grazing, which led to herders arriving earlier and earlier in the year. As bad as sheep can be on a meadow in mid-summer, they are a hundred times worse in early spring, before the ground firms up and before the grass has time to fully develop. It quickly became clear that this was not only unsustainable, it would leave scars in the mountains that would last for decades.

During the negotiations with Congress over the Land Revision Act of 1891, President Benjamin Harrison arranged to have a few words slipped into the bill:

“That the President of the United States may, from time to time, set apart and reserve, in any State or Territory having public land bearing forests, in any part of the public lands wholly or in part covered with timber or undergrowth, whether of commercial value or not, as public reservations, and the President shall, by public proclamation, declare the establishment of such reservations and the limits thereof.”

In 1893 Harrison decided to set apart and reserve part of the Sierra Nevada, and shortly afterwards more than four million acres on the western slopes were declared off-limits to sheep.

The herders, at first, paid little attention. Why should they? President Harrison wasn’t around to chase them out. Eventually, the Unites States 5^th Calvary was called to police the forest, including Yosemite. (The unit in Yosemite was led by First Lieutenant N. F. McClure, who would name one of the passes out of the park after one of his NCOs: Sergeant Donohue.) Even then it took years for the government to gain the upper hand. At one point, sheep herders went as far as hiring a network of scouts, trained to locate the army and signal their location and direction of movement via signal fires.

Eventually the sheep were evicted, although they did return for three years during the latter part of World War I.

Good hiking, Ray
