THE SWEDISH MOOSE POPULATION EXPLOSION, PRECONDITIONS, LIMITING FACTORS AND REGULATION FOR MAXIMUM MEAT PRODUCTION
The recent sudden increase in the number of moose in Sweden is discussed. In 1978, 12 million kg carcass was obtained by killing 94,000 animals. The high fertility rate, the abundant feed supply and the regulated, animal licensed, hunting are considered to be the main factors causing the increase in moose number.
Among the limiting factors, climate in terms of snow cover depth seems to be of some importance. The effect of air temperature and predators seem to be insignificant. The main limiting factors in the near future seemed to be the availability of metabolizable energy and the demand for better road safety.
The use of population simulation studies for maximum meat production from a winter stock of constant size is also discussed.
Finally a group of problems in urgent need to be solved is listed.
