Has anyone ever used an Alternative Compliance Path to earn SSc5.1? The LEED Definition of 'Native or Adapted' Plantings seems very narrow in the Credit Requirements page (pg 77), and less narrow in the definition section (Section 13 in the Credit Language). Our project is following a state-wide definition of native or adapted plantings called 'Florida Friendly Landscapes' (developed by University of Florida, local Water Management Districts, etc.) which certifies plantings as adapted or native, and plants that create habitat, etc. The LEED language from pg 77 'Native or adapted plants are plants indigenous to a locality or cultivars of native plants that are adapted to local climates" seems to remove the true definition of 'adapted (or introduced) plantings' listed in Section 13.

There does appear to be a slight difference in language between the definition on page 77 and the one you mentioned in section 13 on page 84. I don't think any addenda have made any changes to these two definitions (though you'll want to check for sure) so it seems reasonable to follow the more detailed definition of "adaptive" on page 84. You'll want to make sure any species considered are not on any of USDA Natural Resources Conservation Service lists for invasive or noxious species. See LEED Interpretation inquiries number 1898 and 414 for similar cases.

Thanks for the LI numbers (easiest way to navigate it). In researching I found LI 185 which states: "A landscape architect can determine if a specific plant species qualifies as 'native or adaptive' for a project location."
And here is an interesting take on turfgrass in the calculations, which goes against reference guide language:
"....If you can demonstrate that the lawn selection, as part of your mixed landscape, meets the intent of the credit, then the lawn area can count towards this credit."
