But, it doesn't seem like there should be anything special about the number 1000 when $b=r$.

What's wrong with the model that makes it give such stupid answers? This idea seems reasonable. This requirement reflects the reality that you cannot determine $r$ and $p_0$ exactly, so you cannot propose to adjust the strategy based on these unknown values. Your task is to determine if this control strategy is a viable approach for maintaining a stable population of around a thousand rabbits. Calculate the equilibrium of this model.

You can use the mathematical model to test out the proposed strategy using different assumptions regarding the parameters, without risking embarrassment if they fail. Mathematically, the rabbit population growth rate is proportional to the number of rabits. The applet you created to simulate model \eqref{fixedremoval} is below. Start with the case $a=0$, focusing on the proportional model \eqref{proportionalremoval}.

You are glad you decided to test the model before trying to implement this rabbit control strategy. In order to fix the problem, you decide you should allow the removal rate to depend on the population size, replacing the fixed rate $a$ with a function $h(p_t)$ of the population size $p_t$. For starters, you calculate the equilibria.
