THE ECONOMICS OF A STAGE-STRUCTURED WILDLIFE POPULATION MODEL
Jon Olaf Olaussen
A four-stage model (calves, yearlings, adult female and adult male)
of the Scandinavian moose (Alces alces) is formulated. Fecundity is density
dependent while mortality is density independent. The paper aims to demonstrate
the economic content of such a wildlife model and how this content may
change under shifting economic and ecological conditions. Two different
harvesting regimes are explored: hunting for meat, and trophy hunting.
It is shown how different ways to compose the harvest influences the profitability
while, at the same time, the population levels of the different stages
may only change modestly. It is also shown why different market situations
require different compositions of the harvest, knowledge that is disregarded
in the traditional bioeconomic modelling approach.
