In keeping with their commitment to provide scientific materials online, the Northern Prairie Wildlife Research Center (NPWRC) has posted five scientific papers at their site. These resources were originally published in other journals, but are available here in full, free of charge. All five resources may also be downloaded in full as .zip files. Kenneth F. Higgins and others wrote the first resource on fire effects on the grassland biome of the Northern Great Plains (US/ Canada). It is based on a 1989 US Fish and Wildlife Service document written by the same authors (Extension Circular 761).
