Aldo LeopoldEarly authority on game
management“art of making land produce
sustained annual crops of wild game for recreational use”

Game ManagementScience and art of
changing characteristics and interactions of habitats, wild animals, and humans to achieve wildlife population goals

FoodWildlife are often
classified by the type of food they eat
Herbivores – plant eatersCarnivores – meat eaters
![Page 8: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/8.jpg)
FoodInsectivores – insect eatersFrugivores – fruit eatersOmnivores – eat many types
of foods, usually meat and plants
![Page 9: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/9.jpg)
FoodSpermivores – seed
eatersAlso classified by the
amount of food that they eat
![Page 10: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/10.jpg)
FoodEuryphagous – animal that
consumes great varieties of food
Since its choice of food is varied, chance of survival is great
![Page 11: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/11.jpg)
EuryphagousOpossum eats fruits,
berries, corn, worms, frogs, snakes and even mice
![Page 12: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/12.jpg)
StenophagousEats a specialized dietUsually has less chance to
adapt to new food sources it its traditional food supply is not available
![Page 13: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/13.jpg)
StenophagousMore likely to starve in a
food scarce season
![Page 14: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/14.jpg)
CoverIn order for wildlife to
survive harsh weather conditions they must find cover – a place that will protect them
![Page 15: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/15.jpg)
CoverProtection from predatorsRanges from a thicket or a
fencerow to water in the case of beavers and muskrats
![Page 16: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/16.jpg)
WaterOne of the most important
requirements of wildlifeBodies of most game
animals are 60-80% water
![Page 17: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/17.jpg)
WaterImportant in blood
composition, temperature regulation and nutrient transport
![Page 18: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/18.jpg)
WaterWithout an abundant
supply of fresh water an area will soon become desolate of wild game
![Page 19: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/19.jpg)
Home RangeArea over which the game
travels is called its home range
Area may be as small as an acre or as large as a township
![Page 20: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/20.jpg)
TerritoryArea that an animal will
defend, often to the deathAnimal’s home ranges
may over lap but territory never will
![Page 21: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/21.jpg)
TerritoryOnly exception to territory
overlap is during mating season
![Page 22: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/22.jpg)
Management proceduresMost common methods
include:Game refugesHabitat development and
improvement
![Page 23: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/23.jpg)
Common methodsCoordination with other
resourcesHunting regulationsPredator controlArtificial stocking
![Page 24: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/24.jpg)
Game RefugesSet aside land for the
protection of wildlife species
Refuges, reserves and wilderness areas
![Page 25: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/25.jpg)
Game RefugesProvide the basics for
survival without the threat of hunters
Early refuges were for private use
![Page 26: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/26.jpg)
Game RefugesFirst state reserve was
established in 1870 in California
![Page 27: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/27.jpg)
Game RefugesAreas for nesting birds,
migratory waterfowl, pelicans, and large game animals have been established since 1870
![Page 28: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/28.jpg)
Game RefugesNot the answer to all
wildlife problemsOnly protect wildlife from
hunters, not their natural enemies
![Page 29: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/29.jpg)
Game RefugesDo not protect the animals
once they leave their boundaries
Only part of total game management plan
![Page 30: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/30.jpg)
Habitat development To increase game
populations, habitat must be developed and improved
Common methodsFencerow plantings
![Page 31: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/31.jpg)
Fencerow PlantingsProvide food and shelter
for wildlifeFarmers provide area at
the end of rows for wildlife habitat
![Page 32: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/32.jpg)
Woodland ManagementNot allowing livestock to
graze in woodlands increases game carrying capacity
![Page 33: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/33.jpg)
Coordination w/other resourcesKeep in mind that all
resources work together
![Page 34: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/34.jpg)
Hunting RegulationsGame was abundant to early
colonists1646 Rhode Island became
first state to establish a closed season on game
![Page 35: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/35.jpg)
Hunting RegulationsLaw was specific for white
tailed deer, it led the way for other states to follow suit
First bag limit was initiated in 1878 by the state of Iowa
![Page 36: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/36.jpg)
Hunting RegulationsAmerican Bison were
plentiful on the plainsProvided food, clothing
and shelter to the plains Indians
![Page 37: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/37.jpg)
BisonWhen the railroad was
being constructed through the west, thousands of bison were slaughtered to feed the workers
![Page 38: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/38.jpg)
BisonMany more were killed as
easterners came to the west and killed bison for their tongues – a delicacy in the East or their hides
![Page 39: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/39.jpg)
BisonThe entire carcass was not
utilized, the remains were left to rot
Legislation by Congress tried to head off extinction……
![Page 40: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/40.jpg)
BisonThe bill was vetoed by
President GrantLaws passed later, but
Bison were almost extinct
![Page 41: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/41.jpg)
Hunting RegulationsHunting is controlled on
both public and private lands
Game populations depend on many factors
![Page 42: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/42.jpg)
Hunting RegulationsReproduction rates,
climate, disease, habitat, and predators
![Page 43: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/43.jpg)
Hunting RegulationsBag limits, hunting
seasons and closed seasons for a given game species must be changed each year in accordance with the population
![Page 44: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/44.jpg)
Predator ControlMedium sized and large
predators can be dangerous to people
Predators can be a threat to domestic livestock and wild game
![Page 45: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/45.jpg)
Predator ControlPredators help to maintain
an improved game population by killing weak or diseased animals
![Page 46: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/46.jpg)
Artificial StockingIntroduction of exotics –
species new to the areaUsually done to supply
predators for a problem game animal
![Page 47: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/47.jpg)
Artificial StockingThe rabbit – once
introduced in Australia soon became a major pest
![Page 48: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/48.jpg)
Artificial StockingExamine the desired
population density or an area
Estimate the carrying capacity

Population DensityNumber of game animals
in a defined areaCan easily become a
problem of over population of a game species
![Page 50: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/50.jpg)
Carrying CapacityAmount of game for which
a given area will provide the essentials for life
![Page 51: Game Management](https://reader036.vdocuments.mx/reader036/viewer/2022062501/56816866550346895ddec74f/html5/thumbnails/51.jpg)
Population DensityMismanagement can lead
to starvation , unhealthy animals and possible disease problems due to weak animals with poor resistance
