Comparative accuracy of population estimators for enclosed small mammal populations

摘要: With the use of statistical methods it is possible to forecast extent damage in farm crops done by big game (red deer and wild boars). Mathematical model for a definite number animals ecological environment on area was solved with aid multiple regression analysis. Studies, carried out during years 1973-1975, included 23 lowland forest districts situated within Silesian Land. Data collected each district concered size animal populations, information environmental characters related their behaviour, as well value inflicted crops. There were obtained equations illustrating economic aspects situation prevailing hunting grounds.
