This year of no spring delayed migration from Wyoming’s high desert for weeks-

The famed Jackson Hole pronghorn herd which winters in the high desert 150 miles to the south has been beleaguered by natural gas development and subdivsions. In recent years, Wyoming Game and Fish and numerous other interests have worked to keep millenia-old migration route open despite human impacts.

This year deep snow delayed the migration (an epic migration that goes back at least 6000 years) to the latest date on record, June 10. Pronghorn numbers are down by a third and an unknown number of fawns might have perished.

The Jackson Hole News and Guide has a detailed story. Pronghorn arrive late, new moms may be lagging. Biologists wonder what delayed migration could mean for fawns. By Cory Hatch.

    An important question is this, because the migration is knowledge passed from generation to generation, will pronghorn that decided not to cross the wintry divide into Jackson Hole, now summer to the south and their fawn fail to learn the migration route?

‎"At some point we must draw a line across the ground of our home and our being, drive a spear into the land and say to the bulldozers, earthmovers, government and corporations, “thus far and no further.” If we do not, we shall later feel, instead of pride, the regret of Thoreau, that good but overly-bookish man, who wrote, near the end of his life, “If I repent of anything it is likely to be my good behaviour."
