Wolf locations for this report were obtained from flights conducted between 29 and 30 April 1998.
All wolves being monitored via radio-telemetry remain within the experimental area, most on national forest land. Twenty-three radio collared wolves being monitored are paired or packmates. Six of 8 Idaho wolf packs produced pups in 1997. Five additional wolf pairs have established home ranges in Idaho and may produce pups in 1998. Three of these wolf pairs include wolves that either were not part of the translocated experimental population, or are wolves with failed radios.
