     Bird Banding Lab at Patuxent Wildlife Research Center—Laurel, MD

          Jennifer Malpass, Biologist,, 301-497-5804
I am passionate about increasing capacity for wildlife conservation by broadening the ranks of wildlife professionals as well as conservation stakeholders. Valuing diversity is the foundation of the business model for the wildlife profession. In the field, wildlife professionals manage landscapes for biological diversity. We work to maintain diverse habits and species, recognizing that diversity provides capacity to adapt to changing conditions. In interactions with stakeholders, we strive to uphold the public trust doctrine: all people share in the ownership of wildlife and all have a responsibility for it. In our workplaces, we collaborate in recognition that no single person or organization has all of the necessary resources- knowledge, personnel, or material- to effectively manage wildlife. I joined PSW in 2020 and have been a DOI Diversity Change Agent since 2018.
