Sustainable Harvest - Midterm Flashcards
What are the three categories of hunters?
- Meat hunters (40%)
- Sport hunters (38%)
- Nature hunters (18%)
What are the two categories of anti-hunting/trapping groups?
- Humanistic attitudes
- Moralistic attitudes
What is the general support for hunting?
- 80% to 90% support for hunting
- Less than 15% support trophy hunting
What is “doomed” or “allowable surplus”?
- Number of species that are allowed to be hunted to meet carrying capacity
Describe compensatory mortality.
- Hunting removes the same number of individuals from the population than natural mortality would
Describe additive mortality.
- Hunting removes more individuals from the population than natural mortality
When are populations growing at their fastest rate?
- Half carrying capacity!
Describe the concept of Maximum Sustainable Yield (MSY). Draw graph
- The largest average yield that can be continuously taken from a population without threatening the population, keeping the population at a sustainable
- MSY is half carrying capacity (k/2)
What are the concerns with MSY? (3 points)
- Assumes certain factors (population size, population growth rate, harvest levels) are known exactly
- Assumes carrying capacity is relatively stable and predictable (winter is the most limiting time and hunting is concentrated in the fall which may add pressure to populations if winter is harsh and a large number was harvested)
- Unsure of “allowable surplus” remains relatively stable from year to year, are subject to fluctuation over short periods of time.
What is Optimum Sustainable Yield, and why is it a better approach?
- OSY suggests that 25% of the population can be harvested yearly, permitting another 25% to natural mortality.
- This approach allows for uncertainties like habitat quality, weather patterns, and future conditions
How are BC harvest rates compared to MSY?
- Only 6% - 15% of population are harvested
What is the BC resident hunter number (now the FWID)?
- card required to purchase hunting and species licences in BC
What is CORE?
- Conservation Outdoor Recreation Education course required to get your BC hunter number (FWID)
What is Limited Entry Hunting? Where do you find information on LEH?
- Region specific, only a specific number, must pay to have your chance to be selected, only those selected can hunt
- Information is found on the LEH synopsis
What is General Open Season?
- Open to anyone with a valid hunting licence for that year
