Both the Porcupine and 'Central Arctic Herds are biologically healthy. After a long period of stability at around 100,000 animals, the Porcupine Herd began to grow steadily during the late 1970s and 1980s and reached 180,000 animals by 1989. The herd then decreased during a series of severe winters and was down to 160,000 in 1992. In 2002, the Porcupine Herd numbered 123,000, but the caribou were in excellent physiological condition.

Drilling for Oil in Prudhoe Bay was started in 1975. Radical environmentalists predicted the demise of the caribou, but they were wrong---instead the herd size has grown dramatically.

It’s interesting to note that the facts are presented logically, and with backup links, regarding caribou in Prudhoe Bay before and after the oil exploration, and the left immediately resorts to their two standard responses. First, they lie. Then, they call you names (see below, leftist lies about Caribou not being in Prudhoe Bay, then calls the fact presenter an “idiot”.

See below from http://www.anwr.org/features/pdfs/caribou-facts.pdf , the fact that Caribou are thriving in and near the oil development is well documented and backed up by the Alaska Dept. of Fish and Game, the Argonne National Laboratory, and actual physical visits to the area.

Also see picture at link, “Central Arctic Herd near Prudhoe Bay on Alaska’s North Slope.”

Are caribou affected by oil development on the North Slope? It
would appear not, based on the growing population of herds
that use land in the existing oil fields in northern Alaska. The
population of the Central Arctic caribou herd, which migrates north each
summer into the oil fields near Prudhoe Bay, has been growing about 8.5
percent per year. Alaska Dept. of Fish and Game biologists counted 31,857
caribou in aerial surveys of this herd in July 2002. In July 2000, fish and
game biologists counted 27,128. In 1997, the count was 19, 730.
Caribou herd populations rise and fall with natural cycles, but one
explanation biologists have for the increasing population of the Central
Arctic Herd is good calf production and survival, and high survival of adults.
Pregnant caribou cows in the Central Arctic herd bear their calves on
lands within or near operating oil fields. Some calves are born within a few
hundred meters of oil field roads.
The Alaska Dept. of Fish and Game findings are backed by the
Argonne National Laboratory. Argonne found no evidence that oil development
harmed the Central Arctic Herd in the lab’s work on the
Environmental Impact Statement for an extension of the Trans-Alaska
Pipeline System federal right-of-way.
