Yellowstone attracts scientists from all over the world. Currently approximately 200 research projects take place in the park each year, with topics ranging from wildlife to volcanism, insects to microorganisms.
Permits are required to conduct research or collect specimens in the park. Scientists must submit an application, study proposal, and peer reviews for permit consideration. A research permit allows scientists to do things that would otherwise be prohibited in a national park. With special permissions, come special responsibilities for the scientists to conduct respectful, low impact research and minimize their traces in the field.
