Biography

Heather Tallis is Global Managing Director, Lead Scientist for Strategy Innovation for The Nature Conservancy, the world’s largest environmental organization. She is a recognized scientific leader in bringing human well-being considerations into conservation. Previously, Tallis served as the first female lead scientist in the history of the Conservancy. She directed the Human Dimensions Program, an initiative that incorporates ecological, social and economic sciences so that human well-being is integrated into conservation practice from the planning stage forward.

Heather has developed, planned and executed many innovative research programs at the Conservancy. Her recent initiatives include:

  • Using data and publicly available test scores to explore the connection between nature views and elementary school test scores.
  • Analyzing available data in the United States to identify which individual choices can have the biggest impact on water scarcity in drought-prone regions.
  • Expanding the definition of poverty beyond income, and moving beyond arbitrary poverty lines in the US and developing countries, to better inform economic and conservation programs.
  • Exploring landscape-level connections between wildlife, livestock, tourism, income, nutrition and tick-borne disease in Northern Kenya.
  • Incorporating ecosystem services in national planning.

Before joining the Conservancy in 2013, Heather was lead scientist at the Natural Capital Project, where she led the development of a pioneering software application (InVEST) that reveals the ecosystem service costs and benefits of land and water use decisions. At the Natural Capital Project, Heather also helped develop a new free software tool — RIOS — which uses biophysical, ecological and social data to help policymakers and others maximize the feasibility and effectiveness of watershed investments. RIOS will be used to design 40 new water funds in Latin America and Africa. 

Tallis has worked with governments, corporations and non-governmental organizations to use science about nature’s benefits to inform a host of policy and planning decisions. She has guided research with diverse stakeholders across the globe and holds leadership and has held expert advisory roles with the World Bank and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services. 

She holds a Ph.D. in zoology from the University of Washington and Master’s degrees from the University of Otago and University of California, Santa Cruz, where she is now adjunct faculty. She is co-editor of the book Natural Capital: The Theory and Practice of Mapping Ecosystem Services, released by Oxford University Press in 2011.
