Black-tailed Prairie Dog Colony Expansion and Forage Response to Fire/Grazing Interaction
SEAFWA Journal Volume 1, March 2014
Restoring historic fire/grazing interactions and increasing the population of the black-tailed prairie dog (Cynomys ludovicianus), a keystone species, are two management priorities for North America's grasslands.
