up to 50 individuals
Herd Size: More than 40, up to
300 individuals

only
Conservation and
Management
 Pigs and Peccaries Specialist Group:
“Maintain core wild populations of not less
than 2,000 animals each taxon in each
individual reserve. . .”
 Maintaining accurate counts
 Game Survey Counts: Late Feb or early
March hunting season
 Trapped animals
 Scat analysis
 Mailing questioneers
 Cameras in peak areas
Management Through
Hunting
 Day (1976) Rest Rotation
 Sustainable harvest levels set by
annual census
 Problem:
 Determination of annual census
 Non-seasonal, unpredictable breeding
makes it difficult to set viable hunting
regulations to avoid killing pregnant
or lactating individuals
 Utilization of peaked breeding times to
avoid this
Management Through
Regulation
 Monitor and regulate the legal trade of peccary hides
and meat markets
 Control poaching
 Establish viable genetic populations in ecological
interconnected reserves i.e. corridors
Management Through
Relocation
 Common in U.S.
 Large scale relocation: Cuba in 1930, unsuccessful
because of hunting (Mayer and Wetzel 1987)
 Need a large enough size of suitable, protected habitat
 Captive Breeding:
 Currently successfully commercial breeding for meat and
hides of Collard Peccaries, no such commercial exists for
White Lipped Peccaries
Management Through
Habitat Conservation
 Need for parks and reserves of suitable size and
habitat
 White Lipped- “It is uncertain whether the existing
networks of reserves is adequate to ensure the
survival of representative populations sufficient in
size to maintain viable populations in all major habitat
types within its distribution” (Altrichter 2012)
 Reduced habitat destruction/degradation
Future
Collared Peccary is more adaptable to man-made
environmental changes, not susceptible to population
pressures – looks bright!
White-Lipped Peccary long term population viable for the
majority of current habitat is poor
 Habitat destruction
 Intense hunting pressures
 Possible epizootics
