As suburbs developed in New England, the forest habitat became more patchy, resulting in the disappearance of some species and the proliferation of mice - which are the reservoir for the Lyme spirochete -- and ticks, which carry the disease to humans. This increased the proportion of infected ticks, and led to an increase in human disease. Video Ref: www.learner.org
