Abstract

Describing historic wildlife communities is important for evaluating changes in ecosystems over time and developing contemporary objectives for conservation and restoration. The early historical record in the Greater Yellowstone Ecosystem (GYE) has been analyzed many times using a small number (~20) of written accounts, with interpretations vigorously disputed among historians, scientists, and other stakeholders.

We compiled a comprehensive narrative of thousands of first-hand accounts of wildlife in the GYE during 1796-1881 to enhance understanding of the native wildlife community. We quantitatively summarized and queried information in a georeferenced database to clarify conflicting past perceptions and gain insights for contemporary management. Analyses suggested wildlife was plentiful and widespread in the GYE prior to Euro-American colonization, with a community composition similar to modern times. However, bison were eliminated from some areas (e.g., Snake River Plain) by the 1840s and there was considerable slaughter of many wildlife species during 1871-1885. In their accounts, observers preferentially mentioned larger species based on their personal and professional interests. Mammals smaller than deer were rarely mentioned and there was a bias towards visual evidence rather than sign or sounds.This analytical approach of compiling large numbers of written accounts, categorizing them in a relational database, and analyzing output from queries could be used in many areas to clarify historic wildlife conditions and provide reference information for modern conservation decisions.
