Based on catch data from an open population of animal exposed to a grid of traps for several days, we can accurately & precisely estimate the population density (abundance). We assume animals are terrestrial (not water or air), individual (not herd), and mobile but not too mobile (e.g., mice not snails or leopard). Selecting an appropriate trap spacing is important. The appropriate trap spacing depends on intrinsic animal behavior. If it’s bad, it is clear and clear how to change it.
