Designing Sustainable Landscapes (DSL) is a landscape conservation project applied to 13 states in the Northeastern United States. The purpose is to provide guidance for strategic habitat conservation by assessing ecological integrity and landscape capability for a suite of focal species across the landscape. Assessments are done for both the current landscape and potential future landscapes, as modified by models of urban growth, climate change, and sea level rise.
Designing Sustainable Landscapes is a project of the Landscape Ecology Lab at the University of Massachusetts (Bradley Compton, Ethan Plunkett, Joanna Grand, William DeLuca, and Scott Jackson, with significant contributions from Kevin McGarigal, Liz Willey, Andrew Milliken, and Scott Schwenk). It is supported primarily by U.S. Fish and Wildlife Service, North Atlantic-Appalachian Region, with additional support from the Northeast Climate Adaptation Science Center (NECASC) and the University of Massachusetts, Amherst.
Highlights of this update include:
We are happy to announce a new version (version 5) of many of the DSL data products, as of March 2020. This update concentrates on improving source data, bringing in the latest versions and correcting a large number of errors. We have updated the landcover and many of the ecological settings variables, and rerun the integrity metrics, the Index of Ecological Integrity, and the focal species models, and updated most elements of the Landscape Conservation Design (Nature’s Network). We have not yet updated the SPRAWL urban growth model, climate data, the sea level rise model, future species projections, ecological impact metrics, aquatic cores, and future elements of the Landscape Conservation Design. We plan to update these in the next few years. For now, the elements that have not been updated (version 3) are still valid, but data will not necessarily match the updated elements. Highlights include:
- A new species model for the spotted turtle (Clemmys guttata) and species-specific landscape conservation tools, including conservation cores, connectivity, and road-crossing vulnerability.
- The representation of development has been vastly improved with the inclusion of Microsoft’s building footprints.
- The Nature’s Network landscape conservation design cores now use the second edition of The Nature Conservancy’s Resilience, which includes the new coastal resilience.
- New data for roads, road-stream crossings, and dams.
- Significant improvements in the NHD stream linework, with several thousand errors fixed.
