Abstract: Connectivity modeling has been a tool available to the conservation community since the 1980s that guides our responses to habitat fragmentation. While the sophistication of computer modeling continues to grow, on-the-ground delivery remains challenging and lacks urgency. We present an approach to scale up delivery and do so within effective timeframes. The approach, termed ANCHOR (Areawide Networks to Connect Habitat and Optimize Resiliency), is grounded in connectivity science but executed in a manner that is flexible, expandable, and measurable. ANCHOR goes beyond the traditional protected area focus for establishing connected biomes to maximize the contributions of existing public lands and expand private landowner participation. The approach is applied using an umbrella species to represent a faunal group and/or multiple taxa to deliver co-benefits of landscape connectivity. Public lands receive connectivity rankings that are then used to engage potential connectivity partners who commit land units and collectively monitor improvements in habitat quality and landscape resiliency. The ANCHOR approach can guide unprecedented participation across agencies and departments to create public lands networks, while private and corporate lands establish landscape connections. To illustrate the approach, we present an example of native grasslands conservation in the central and eastern U.S. and an emerging partnership with the Department of Defense.
