The National version of the RCN follows consistent methods across the United States as described in Anderson et al. 2023 A Resilient and Connected Network of Sites to Sustain Biodiversity under a Changing Climate published in the Proceedings of the National Academy of Science.

The augmentations reflect local site knowledge, field checking of connectivity linkages, and restoration work to restore resilience.

Additions to the customized RCN include:
