Wildlife Science Unit 1: Introduction to Wildlife Management
Wildlife Management
Balance the needs of wildlife with the needs of people using science
Common practices include:
Hunting/Fishing/Trapping
Selective burns and tree cuttings
Food plots
Conservation areas
6 Principles of Wildlife Management
Carrying Capacity
Limiting Factors
Territorialism
Harvestable Surplus
Cycles
Inter-dependence
Carrying Capacity
Maximum population of a species that an environment can provide for, given the water, food, habitat, and other resources available
What resources are needed?
Important Components
Water
Food
Shelter/Habitat
Cover, nesting, escape plan
When resources disappear, animals become:
Aggressive
Less reproductive
Why are there changes in CC?
Increase in resources---animals/plants
Natural Disaster
Disease
Environmental Stresses---use all resources
Technology
Limiting Factors
Forces that holds back a population
Slows the growth
Food, Water, Shelter, Space
Lack of something essential
Abundance of something bad
Improve by identifying the most prominent limiting factor and reducing it
Territorialism
A behavior in which animals establish and defend living and hunting areas against other competing members of their species
Harvestable Surplus
Number of animals that can be harvested from the population w/o long-term effects
Maintain stability of the population
Approximately 1/3 of the full population may be harvested
How?
Hunting
“Natural” Mortality
Predator/Prey
Disease
Accidents
Starvation
Cycles
Annual Cycle for each species (short term)
Lowest population right after winter and highest in the spring
Predator/Prey Relationships
Natural Disasters
InterDependence
Plants and animals live in a complex, interrelated community
Everything works together and taking one thing out will reduce one and allow another to flourish
Decision-makers must understand the relationships to deal effectively
