Free Admission Sunday from 10:00am - 5pm at Lincoln Park Zoo - see INFO below. Animal Welfare refers to an individual animals overall quality of life as experienced by the animal.

We study how different demographic, genetic, and management strategies affect long-term population health and viability, and assist managers across the zoo community with applying those principles to manage populations.
