Success Strategies
And Wildlife Management
 Wildlife
managers need to identify
• population size and carrying capacity
• critical habitat
• food requirements
• Nesting/breeding requirements
• Symbiotic relationships
• Special species needs
 Census
(counting
each individual)
 Random Sampling
(estimating
population size from
smaller sample)
 Habitat
management and improvement
• Setting aside reserves, coordinating with private
landowners
 Connecting
fragmented habitat allows
animals from each smaller area to safely
get to other areas.
 Habitat
management and improvement
• Creating artificial nesting sites (Red cockaded
woodpecker in Eastern Texas) saves the bird
time so they can reproduce more frequently
 Federal
program
 Pays land owners to put marginal lands
back into native vegetation to provide
wildlife habitat
 31.4 million acres currently
 Removal
of invasive
species, replanting
native species, using
prescribed burns
 Individuals
are
captured in wellpopulated areas and
moved to lesspopulaed areas
 Increases genetic
biodiversity
 1996
wolves
reintroduced in
Yellowstone
 Camera
traps on
trees. When an
animal crosses the
infrared beam of light
a picture is taken.
Wildlife managers
can tell exactly when
the animal was there.
 Usually
with egg-
layers –
birds/amphibians
 Young are raised until
they can survive on
their own in the wild
and then released
 Genetic
index of
endangered species
 Cross breeding of
distantly-related
individuals to
improve the
population
 Radio
collars can be
put on
birds/mammals to
keep track of what
habitat they use and
whether they are
alive or dead.
