1 Fish and Wildlife in America

2 Renewable resources usually taken for granted we have developed an attitude that there will always be more Animals fall into this category

3 Renewable resources ability to reproduce many species have died out management of wildlife resources is important

4 Wildlife living things that are neither human or domesticated especially birds, mammals, fishes includes both plant and animal life

5 Wildlife we will concentrate on higher life forms vertebrates lower forms of plant and animal life are also important in maintaining a balance

6 United States estimated that the continental U.S. contains over 2,300 different vertebrate species. Game animals make up only a small portion of this number

7 Early Pioneers depended on these birds, mammals and fish to survive meat supplied food skins used for shelter and clothing oil kept firearms usable

8 Early Pioneers oil used to light cabins with out wildlife resources the wilderness would have never been conquered.

9 World Fur Trade America was well established at the cost of wildlife trappers took the animals faster than they could multiply treated the resources as a crop

10 Wildlife killed many because they appeared hostile bears, wildcats - danger to people many species were killed because they threatened the safety of domestic animals

11 Wrongly accused hawks were thought to kill chickens mass destruction of hawks took place

12 hawks stomach contents found to contain 40% insects, 30% frogs 23% rats and mice, 3.4% small birds 2% aquatic wildlife

13 stomach contents.5% game birds.5% rabbits

14 Red Tail hawks poultry parts were discovered but those parts were only a small percentage of the diet original premise was unfounded.

15 Rare or Endangered few in number 1966 Endangered Species Preservation Act Endangered Species Conservation Act

16 Congressional Acts protect fish and wildlife on a worldwide basis protection and conservation of species of native fish known to be threatened with extinction

17 1969 amendment dealt with importation of endangered species into the US from anywhere in the world called for formation of an endangered species list

18 1969 amendment list is updated every 5 years 1970 the list contained 133 species of mammals 124 birds, 24 reptiles 25 fish, 1 mollusk

19 Extinct species no longer exist outside of museums or photographs

20 Rare species one that is no longer common in danger of becoming extinct zoos may hold the last examples of the species

21 Extinct Species Passenger Pigeon at one time the population was thought to be in the billions flew in enormous flocks John Audubon estimated on flock he saw at over one billion

22 Passenger Pigeon large flocks would strip all the foliage leaving the area bare people declared war on the birds killing all they could find

23 Passenger Pigeon captured the young and killed them, shipped them to cities as food flocks soon disappeared NY, PA and MA passed laws to protect them

24 Passenger Pigeon laws were too late birds held in captivity would not breed last known passenger pigeon died in the Cincinnati Zoo in 1914

25 Passenger Pigeon body of last passenger pigeon is on display at the Smithsonian Institute in Washington, DC

26 Extinct Species Carolina Parakeet Heath Hen Labrador Duck

27 Carolina Parakeet sought for their colorful feathers which were used in womens hats final extinction came in 1914

28 Heath Hen relative of the prairie chicken used for food by early settlers bird sanctuary set up in the early 1900s

29 Heath Hen Fire swept through the sanctuary a few males survived last bird died in 1932

30 Labrador Duck became extinct before anyone realized it was gone most birds were killed for their feathers which were used to stuff pillows

32 Common endangered big horn sheep, polar bears, key deer, wolves mountain lions most hunted extensively without considering extinction

33 Big Horn Sheep threatened by extinction from two sides humans and disease large sheep, relatives of domestic sheep

34 Big Horn Sheep live high in the mountains above the tree line 6-7 feet in length have long curved horns

35 Big Horn Sheep are hunted for trophies many carcasses are found with head removed very alert are under protection of game laws some are being kept in wildlife reserves

36 Polar Bears important source of food for Eskimos fur is used for clothing meat is used for food airplane hunting is being used to kill vast amounts each year

37 Polar Bears Females produce only 2 young each year stay with mother for 10 months Canada and Soviet Union have laws to protect these animals

38 Key Deer smallest white tail deer killed for trophies strict laws prohibiting hunting population increased from 30 to 300 because of wildlife refuges

39 Wolves wolves resemble dogs hunt in packs at night pack consists of young and old female bears 5-14 pups in a den guarded by the male male and female mate for life

40 Wolves feed on domestic livestock there have been bounties on wolves now bounties can only exist if the population endanger the deer population
