About our curriculum

Rhizome Restoration's science curriculum was developed in partnership with the EcoRestoration Alliance and draws on peer-reviewed ecological research, published books, and trusted conservation resources. The following sources informed our lesson content, quiz questions, and ecological claims. We are grateful to the researchers, scientists, and organizations whose work forms the foundation of what we teach.

  • EcoRestoration Alliance. Cooling Climate Quickly: The Case for Ecosystem Restoration as Climate Strategy. ERA Whitepaper. Note: This document represents ERA's scientific perspective and advocacy position. Some claims within it reflect emerging or contested science and are presented in our curriculum as ERA's view rather than settled consensus.

National Wildlife Federation

  • National Wildlife Federation. Native Plant Finder: Keystone Plants by Ecoregion. nwf.org/NativePlantFinder. The NWF Native Plant Finder tool, which Rhizome Restoration members use to identify appropriate species for their ecoregion, incorporates Tallamy's keystone plant research into a publicly accessible database organized by zip code.
  • National Wildlife Federation. Why Native Plants Matter. nwf.org. Source for statistics on native plant wildlife support and the ecological value of native landscaping.

Homegrown National Park

  • Tallamy, Douglas W. Homegrown National Park Initiative. homegrownnationalpark.org. The Homegrown National Park concept, which calls for converting half of America's lawn area to native plant communities, is referenced throughout our curriculum as a framework for understanding the scale of the restoration opportunity.

Scientific Studies

Peer-reviewed research

  • Hallmann, Caspar A., et al. More Than 75 Percent Decline Over 27 Years in Total Flying Insect Biomass in Protected Areas. PLOS ONE, 2017. This landmark study documenting dramatic insect decline in protected natural areas is referenced in our Sprout Level curriculum.
