Wildlife harvest models l.jpg

Wildlife Harvest Models

  • Annual surplus model

    • Large mammals

    • Bird populations

  • Maximum Sustained Yield (MSY)

    • Large mammals (control situations)

  • Population control model

    • For pest or eruptive populations


Annual surplus model l.jpg

Annual Surplus Model

  • Hunting takes the annual surplus production that can not be supported by the habitat

  • Based on concept of compensatory mortality

    • That is, hunting mortality replaces other forms of mortality and is not additive


Maximum sustained yield model l.jpg

Maximum Sustained Yield Model

  • Produces the highest harvest from a population

  • Reduces population to half of carrying capacity of habitat

  • Based on logistic growth model

  • Used for deer/elk damage problems on private commodity lands
