Doug Tallamy's journey into the realm of conservation began with a profound fascination for insects. As a renowned entomologist and professor at the University of Delaware, Tallamy has dedicated decades to unraveling the intricate relationships between plants and insects. His research has illuminated the critical role of native plants in sustaining diverse ecosystems, providing essential food and habitat for countless insect species. Through his work, including the influential book "Bringing Nature Home," Tallamy has effectively communicated the urgency of preserving native biodiversity in the face of habitat loss and ecological degradation.
Our own native plant collections rely on the research of Doug. His University of Delaware research team have identified the keystone plants that support 90% of butterfly and moth species. This work is also core to National Wildlife Federation’s Native Plant Finder, which provides zip-code-based lists of Keystone trees, shrubs and flowering plant species.
Homegrown National Park™ represents Tallamy's vision to mobilize communities in the conservation effort. At its core, the initiative encourages individuals to rewild their own properties by replacing non-native ornamental plants with native species. By creating interconnected networks of native habitats across residential landscapes, Tallamy envisions the emergence of a decentralized "national park" that spans the country. This grassroots approach not only fosters biodiversity but also fosters a sense of stewardship and connection to nature among homeowners.
Central to the Homegrown National Park movement is the concept of the "Homegrown National Park Biodiversity Map™." This interactive tool empowers participants to chart their progress in transforming their properties into native plant sanctuaries. By visualizing the collective impact of thousands of small-scale interventions, the map serves as a testament to the power of community-driven conservation.
To join, simply enter your native plantings (from one square foot up to multiple acres) on the HNP Biodiversity Map
The Biodiversity Map consolidates and amplifies ALL the extraordinary work being done by individuals and organizations across the US and Canada. It provides a dynamic visual that pinpoints where actions are thriving and where they are desperately needed. We invite you to make your contributions known by getting on the Biodiversity Map!
The benefits of Tallamy's initiative extend far beyond the boundaries of individual properties. By restoring native habitats on a widespread scale, Homegrown National Park™ helps combat biodiversity loss, support pollinators, and enhance ecosystem resilience. Native plants not only provide food and shelter for insects but also serve as the foundation of healthy ecosystems, sustaining birds, mammals, and other wildlife. Don't forget: by reducing the reliance on water, pesticides, and fertilizers associated with traditional landscaping practices, the initiative promotes sustainability and environmental stewardship.
Tallamy's movement has garnered widespread acclaim and inspired countless individuals to take action in their own communities. From suburban yards to urban rooftops, people from all walks of life have embraced the ethos of ecological restoration. By cultivating native plant gardens, creating wildlife habitats, and sharing their experiences with others, participants are collectively reshaping the landscape and reimagining our relationship with the natural world.
