  1. Need for Hunting Laws • By the 1930s activities had destroyed much of the habitat of wildlife • Some species had been nearly wiped to extinction from uncontrolled hunting and trapping

  2. Hunting Laws • Hunting and trapping laws left to each state • Except for migratory birds • 1937 – Pittman-Robertson Act placed a federal tax on hunting licenses, firearms, and munitions • Money used for wildlife conservation • 1950 – Dingell-Johnson Act collected taxes on fishing and boating equipment and boat fuel • Money used for fish habitats

  3. PA Animals • 255 species of breeding birds and mammals in PA • 20% of these species can be legally hunted – game species

  4. PA Animals • When wildlife is managed by game agencies, management plans often favor game species • Habitats of non-game species may be destroyed in order to manage land for game animals • Primary method of game management – regulated hunting

  5. Carrying Capacity • Determines the population that can be supported in a given area • In PA: • Largest deer are in counties with dairy farms and timber operations • Smaller deer are in counties with large areas closed to public hunting

  6. Deer • By late 1920s there were no deer in Minnesota, Wisconsin, Iowa, Illinois, Ohio, Pennsylvania, and much of New York • Due to unregulated hunting • Refuges bought with money from hunting permits were stocked with deer from other states

  7. Deer • Hunting was regulated • Strict enforcement of game laws • White-tail deer population is now the most abundant big game species in North America • 20-25 million

  8. Gettysburg National Military Park • Survey conducted between 1987 and 1992 – increase from 721 to 1,018 deer in study area • Population density as high as 447 deer per square mile of forest • Ate tree seedlings and nearby crops • Park couldn’t maintain historic landscapes necessary for understanding historic events

  9. Little Round Top

  10. Bloody Wheatfield

  11. Plum Run

  12. High Water Mark

  13. Gettysburg National Military Park • National Park Service determined that the number of deer needed to be drastically reduced • Between October 1995 and March 1997 858 deer were removed • Venison was donated to local food banks • Goal to reduce and maintain density to 25 deer per square mile

  14. Poaching • Taking of wildlife by any method that is illegal • Studies in Missouri, Washington, and New Mexico show that more animals are killed illegally than legally • Most poaching is done for “sport” or for profit

  15. Other Human Activities • Most human activities result in some negative impacts on wildlife habitats • Developers, dam builders, road builders, and swamp drainers destroy more wildlife than hunters • Our technology often causes the accidental death of many kinds of wildlife • With the exception of hunting season, more deer are killed on highways than by any other means
