The dataset includes specifics on fragments of bullets recovered from shot Belding's ground squirrels from Oregon and California. Ground squirrels were radiographed and then we used ImageJ software to count and measure the area of those bullet fragments. A subset of shot carcasses were then digested and bullet fragments were recovered. Statistical models were developed to predict either the number or mass of bullet fragments in shot ground squirrel carcasses using the radiograph estimates and the digested recovered fragment data.

The Cosumnes River Preserve in the California’s Central Valley contains a mosaic of managed wetlands where conditions may promote high levels of methylmercury bioaccumulation. In order to document potential environmental health risk in these wetlands due to mercury, we analyzed dragonfly larvae, western mosquitofish, and tree swallow eggs collected from wetlands and rice fields of the Preserve from 2011 to 2013.
