Common loon was selected as a representative species for the Designing Sustainable Landscapes project of the North Atlantic LCC (https://scholarworks.umass.edu/designing_sustainable_landscapes/). The habitat clusters (ecological systems) and associated wildlife species that it represents are northern New England lakes. The Landscape Capability (LC) index integrates habitat capability, prevalence and climate suitability into a single index that reflects the relative capacity of a site to support the species.
