The Healthcare Center currently provides for five distinct Functional zones: administration, treatment, research, convalescent holding (including isolation) and quarantine; all of which were grossly undersized due to the growth of the zoo over the past 25 years.

​

​In order to maintain the simple and direct circulation since many of the patients are quite large and must be tranquilized to be moved, the addition of a large treatment room, CT room, imaging zone, intensive care suite and convalescent holding had to be carefully thought out, all while the hospital remained active.

​

As a wide variety of species are treated, each of a different size, temperament and biology, both the convalescent holding and quarantine functions are subdivided into three separate holding zones.  Each zone has a separate ventilation system, durable wall and floor finishes and specialized caging to match the characteristics of the particular animal housed.
