Sustainable Harvest Flashcards
3 general categories of folks who are pro hunting/trapping
- Meat hunters
- Sport hunters
- Naturalistic hunters
Characteristics of meat hunters
- Practical view of animals
- Primary goal is for meat
- 44% of hunters
Characteristics of sport hunters
- View hunting similar to an athletic contest
- Take pride in owning impressive specimens
- “Thrill of the hunt”
- More interested in size/status of individual
Characteristics of Naturalistic hunters
- 18% of hunters
- Exhibit more knowledge of animals and ecology
- Link hunting with fundamental contact with nature
- More interested in the experience
2 general categories of anti-hunting/trapping groups
- Humanistic attitudes
- Moralistic antihunter
Characteristics of humanistic attitudes
- Strongly identify with the feelings of individual animals
- Hunting inflicts unnecessary pain/death
- Objection to hunting occurs from loving animals
- Feelings heightened with attractive animals
Characteristics of moralistic antihunter
- Objections to hunting for more subtle reasons
- Hunting is contrary to human social values
- Identify with ethical and social aspects rather than the individual
General support for/against hunting
- 90% support sustenance hunting (1st nations)
- 70% supported hunting for meat
- 40% supported hunting for recreation and sport
- 4.4% oppose all three types of hunting
Define Compensatory mortality
- Hunting removes the same number of individuals from a population that natural mortality would
Define additive mortality
- Hunting removes more individuals from a population than natural mortality would
- Increases rate of mortality
When are populations growing at their fastest rate?
When the negative feedback from the environment is delayed
What are the major concerns about MSY?
- MSY assumes population size, population growth, the relationship between size and growth, and harvest levels are known exactly
- Assumes carrying capacity is relatively stable and predictable
- Assumes quantity of “allowable surplus” is stable from one year to the next
Why is OSY a better approach than MSY?
OSY is a better approach because it balances:
• Current harvest
• Long-term persistence of the population
• Social/economic factors
How does BC harvest rates compare to that suggested by MSY?
BC Harvest rates: 6%-15%
OSY Suggestion: 25%
What are the key supporting points against trapping?
- Traps cause animals undue suffering
- Taking an animals life for the sake of fashion is immoral
- Trapping kills or maims many non-target species
What are the key supporting points in favour of trapping (5)?
- Harvest data from trappers help managers keep track of fur-bearing populations
- That trapping provides an annual crop of furs that would otherwise be lost to other forms of mortality
- That fur sales help the economic welfare of individuals
- That rabies, distemper, and other diseases are suppressed by trapping
- That the inevitable death of an animal is less painful for a trapped animal than it would be from starvation, predation, or other natural causes
Class 1 species trapping regulation
• Class 1 Species. Species can be managed on individual trap lines. This class includes beaver, fox, marten, mink, muskrat, raccoon, skunk, and weasel
Class 2 species trapping regulations
• Class 2 Species: are those species that move between traplines, and thus are not managed on individual trap lines. Harvest is regulated regionally, in consultation with local trappers. This class includes lynx, bob-cat, wolverine, fisher, and otter.
Class 3 trapping species guidelines
• Class 3 Species: are those species that also move between and among traplines, but generally are not vulnerable to over-trapping. This class includes the wolf and coyote. Trappers are encouraged to trap these
