Yellowstone Bison Experiment

Yellowstone National Park has given permission to APHIS and the USDA to experiment on 100 bison the effects of GonaCon. This is a pesticide contraceptive approved by the EPA. GonaCon is a single-shot immunocontraceptive vaccine. It is effective for 1-5 years. (These people need to use it.)

As part of its program to develop tools for managing populations of overabundant wildlife species, NWRC [National Wildlife Research Center] scientists have developed a new GnRH immunocontraceptive vaccine (named GonaCon™) that shows great promise as a wildlife infertility agent. (Technical discussion on how GnRH immunocontraception works)

GonaCon was originally made to reduce white-tail deer populations, which the EPA has classified as a public health pest.
