A Further Analysis of the Nelchina Caribou and Wolf Data

Simple models were used to examine wolf and caribou population data in the Nelchina Basin of south-central Alaska. Use of a projection method made it possible to back-calculate previous wolf abundance from a sequence of recent population estimates, and an age structured model permitted interpolation between the few historical census points available for caribou. Adult survival rates calculated from the caribou data indicated that, although the sharp reduction in recruitment in 1964-1966 undoubtedly reduced population size substantially, curtailment of female harvests in 1968 would likely have precluded the 'crash' of 1970-1971.
