A scientist is studying the population of a rare species of tree in a remote region. They model the population, $P(t)$, at time $t$ (in years since the start of the study) using a combination of exponential and logarithmic functions:
$$P(t) = 500e^{0.02t} - 100\ln(t+1)$$
Analyse the long-term behaviour of this population model. Specifically, discuss whether the population will continue to grow indefinitely, level off, or decline to extinction. Justify your answer by considering the properties of the exponential and logarithmic components of the model as $t$ approaches infinity.
