New Study Showing Minimal Impact on Caribou Range

Last fall, President Trump approved Alaska’s Ambler Mining Road, which might run from the Dalton Highway close to Wiseman to the Ambler Mining district, a distance of about 150 miles. The function is to enable for simpler extraction and transport of the identified mineral wealth in the Ambler district, which is appreciable, and which incorporates some strategic uncommon earth minerals.

Now, a doable impediment to that street has been eliminated. A examine finished by a Yale-educated biologist, Matthew Cronin, has decided that the great Western Arctic caribou herd (WAH) is not going to be adversely affected by the deliberate street.

At around 150,000, WAH is the most important caribou herd in Alaska. This herd spends its summers and calves in the western area of Alaska’s North Slope and migrates as far south as the Yukon River in western Alaska during the winter.

The population of this herd has dropped from a peak of 500,000 caribou in 2003, raising considerations among Alaska Natives in the western areas of the state that rely on the herd for subsistence. Biologists attribute climate change, predation, and human harvest as the first elements for the shrinking caribou numbers over the past twenty years.

The western half of the proposed 211-mile Ambler Road crosses into the WAH migratory space.

The examine accomplished by Cronin, a researcher at the Northwest Biology and Forestry Company, discovered that the proposed Ambler Road footprint is less than 0.005% of the WAH’s 92.2-million-acre vary and crosses an space seldom crossed during migration.

In case you were not conscious of it, Alaska is a big, big place. There’s room for caribou and a mining street. And the most important impacts on caribou populations aren’t from human actions, in any case:

Other key findings of the report embody:

• The major migration routes of the WAH have been west and north of the proposed street.
• The Ambler Road and related mines are situated over 150 miles away from the Western Arctic Caribou core calving grounds.
• Caribou have efficiently crossed the Dalton Highway and other roads in Alaska and Canada during migrations for many years.
• Predation by bears and wolves, particularly on calves, as nicely as winter climate and icing occasions, are major elements impacting the WAH population.

Icing occasions are notably harmful for grazers and browsers, like caribou and moose. Last winter, when south-central Alaska skilled a extended period of freezing rain and icing, browse was locked away behind ice, and the roadways and drives that moose rely on to transfer around have been as slick as spit on a doorknob; to my understanding, Alaska Fish & Game is still working on figuring out the affect on the south-central moose population.

As for caribou, bears, and wolves are a a lot higher risk than roads. Caribou routinely cross Alaska’s current highways and byways (not that we’ve a lot of them) with impunity. But predation by bears and wolves can account for half of any given yr’s calves.

So, a doable stumbling block has been addressed. It’s not yet identified when construction of the Ambler Road will start, and it isn’t yet identified if the overall public will likely be allowed to use the street for leisure functions. But this is a win, all the same.
