Abstract: Several attributes, including fluctuating population densities, poor dispersal abilities, and patchy distributions, make prairie restricted insects especially susceptible to the high extinction rates associated with severely fragmented ecosystems. Habitat deficiencies, excessive levels of predation and competition, and intensive burning regimes can contribute to the extirpation of these extinction-prone organisms from preserve system comprised predominately of small, widely scattered sites. Managers can minimize insect losses by restoring habitat diversity, by eliminating unnatural landscape features, and by burning with restraint. On a regional level, conservation biologists are urged to minimize the likelihood of insect extirpations by insuring that rare species are established on a minimum number of protected sites within each state.
