Head of the National Wildlife Federation’s Garden for Wildlife™ program and Certified Wildlife Habitat®
Mary leads the National Wildlife Federation’s Garden for Wildlife™ program and Certified Wildlife Habitat® as an ambassador for native plants and the wildlife they support. Her work ensures all habitat programs and resources are rooted in sustainable practices and the latest science. Since 1973, the Garden for Wildlife™ program has been the nation’s oldest and largest Backyard Habitat program generating and supporting millions of wildlife gardeners in North America. Since Mary arrived in 2014, the Certified Wildlife Habitat® program has grown by 64% and has tripled its email subscriptions.
Mary’s strategic leadership aligns the native plant habitat mission across National Wildlife Federation’s, community initiatives, partner networks and external messaging. She collaborates with leading entomologists, pollinator conservationists, federal agencies, the organization’s science team and trend researchers to provide substantive content, to the Native Plant Finder™, Garden for Wildlife resources, and Spanish-language resources. This cross functional strategy has fostered public participation among millions of wildlife gardeners, more than doubled certifications, increased science and civic partnerships and created a Garden for Wildlife state network of 26 affiliate partners.
In 2020, inspired by the work native plants do to restore habitat, and based on consumer demand research conducted with the National Gardening Association Research and input from a survey of four hundred native plant growers nationwide, Mary created the Garden for Wildlife Native Plant Collections™. Curation of these collections was based on the development of ecoregional Keystone Plant lists in collaboration with Dr. Doug Tallamy and his University of Delaware research team. The goal of the social enterprise incubator was to engage everyday people in solutions for critical wildlife loss and climate impact and, connect local native plant growers to consumers through ecommerce. In the two years of the pilot launch (2021-2022), sales grew by 300%, distribution expanded from twenty-one to thirty-eight states and from two to five regional growers.
In coordination with the White House Office of Science and Policy, Mary co-founded the National Pollinator Garden Network in 2015 to launch the Million Pollinator Garden Challenge which created over a million pollinator gardens in three years. This partnership involved more than 50 national organizations with a third from the commercial garden trade, such as growers and independent garden centers. During this same time period, Mary launched the Butterfly Heroes™ Pledge which resulted in close to 500,000 participants receiving native milkweed seed to create monarch gardens nationwide.
