Abstract: Precise and unbiased estimates of survival and mortality patterns are needed to
understand population dynamics of bobcats (Lynx rufus). Bobcat pelts were at a high
demand 20 years ago. As a result, bobcat populations had to be monitored, even now, to
make sure that the decline of bobcat populations would not decrease again as it did in the
past. By using the Pop-2 computer model, we are able to predict what percentage of an
increase in harvest will effect the population and if it will crash. A 10% increase in harvest
will decrease the population at a stable rate while a 30% increase will crash the

Such as furs from other wild cats, the bobcat's fur contains beauty. As a result,
bobcat pelts have been demanded by people in the past which caused an increase in
harvest of the bobcat. The hunters searching for this creature saw this as an opportunity
to make lots of money. But since then, in recent years, bobcat pelts have decreased in
price. This caused a decrease in the hunting of the bobcats. But during those times of
high harvest, wildlife agencies had to keep up to date on their population. Even now,
agencies have kept monitoring bobcat populations. They know that a harvest increase
greater than 20% can cause the bobcat population to seriously decline to very low levels;
even cause a crash (Knick 1990). What if the demand of pelts occurs again? The purpose
of this paper will illustrate what an increase in harvest (10% and 30%) will do to the
bobcat population if the pelt situation occurred again in the future.
For a sensitivity analysis, I ran the Pop-2 computer model. I used the bobcat
model twice to determine the outcome of an increase in harvest on the population. I
printed out the original population numbers labeled table 1 and table 1A before any
changes to the database had been made. This wa...
