Evaluating immunocontraception for managing suburban white-tailed deer in Irondequoit, New York Evaluating immunocontraception for managing suburban white-tailed deer in Irondequoit, New York
Immunocontraception is frequently proposed as an alternative to lethal removal of females for deer management. However, little information is available for evaluating the potential of applying immunocontraceptives to free-ranging populations.
