Question
Here is the full question. I need help on the 2nd half about taking measures to reach a stable a stable population.
Deer have become increasingly apparent in a rural county. Last year it was estimated that there were 40 breeding pairs (a deer must reach the age of 1 to breed). A pair of deer produce an average of 1 fawn per year, and 80% of these fawns grow to reach 1 year of age. 10% of adult deer die of natural causes each year. An average of 5 adult deer are killed annually in highway accidents, and 2 per year in illegal hunting. Use difference equations to estimate the population of deer. Do you think it is likely that the deer population in the county is increasing? Will the deer population eventually reach equilibrium?
You are asked to take measures reach a stable (non-zero) population of deer. These could include: doing nothing; making hunting legal up to 10 deer permits per year; measures to reduce deer kills by cars (which can be 60% effective); birth control for deer (which can be 80% effective); or importing deer into the county. What would you do (you can use a combination of actions if you like)?
Explanation / Answer
The important measure to be taken for reaching a stable population is by making hunting legal upto 10 deer permits and also measures to reduce deer kills by cars per year, which will make the population stable. Apart from this, there are natural ways like 10% of adult deers die of natural causes, an average of 5 deer are killed in highway accidents, and 2 in illegal hunting per year.
