Abstract
Revenues from oil and gas development play a key role in the economies of many states in the United States, but there are environmental concerns such as local air and water pollution, land cover changes and fragmentation, and negative effects on wildlife. These concerns were exacerbated as oil and gas production reached historic highs due to the expanded use of hydraulic fracturing technology beginning in the mid-2000s. This paper examines the influence of oil and gas development on breeding bird communities in the High Plains ecoregion of Colorado between 2003 and 2018. Specifically, we investigated whether oil and gas drilling or production affected species richness or evenness of bird communities. Our findings indicate that a decrease in producing well density or the number of producing fracking wells were associated with an increase in evenness of the overall bird community and grassland species richness, but disturbances from well drilling generally did not have a statistically significant influence on bird communities. We also found that a decrease in tree cover was associated with an increase in species richness and evenness of the overall bird community.
