A prior process-based model of the <i>Ixodes scapularis</i> (Say 1821) life cycle and the transmission of <i>Borrelia burgdorferi</i> (Burgdorfer 1982) between this tick and its various hosts was used to predict the dynamics of disease introduction into a new area.

The results of those samples were analyzed to determine the time to near-equilibrium. Eight locations in New Hampshire were chosen for high/low temperature, high/low mouse, and high/low deer values. Mammal abundance was estimated by relating the known mammal density from previous studies to a MaxEnt analysis output.
