How can history impact a species’ future? Bison were nearly driven extinct in the late 1800s by overhunting and ranching. Today, scientists at Theodore Roosevelt National Park and across the continent are studying bison DNA to discover how that chapter of history changed their gene pool — and bison themselves — forever.

Get the inside scoop on how park rangers and researchers collect DNA from bison in the field! In this video, bioscience technician Melissa Thompson explains the technique used to collect genetic samples without endangering the researchers or the animals. DNA from these samples is used to measure the genetic diversity of the herd, and gives us the tools to preserve genetic diversity here in the park, and across the continent.
