The list may be missing species that have been documented in the park, and some species may be removed if no voucher specimens are located. National Park Service staff are still rectifying nomenclature and ensuring that all recent collections are included in the list. There will be additional changes over time to this list as we continue to document voucher specimens and collect plants in the field. This metadata field will be updated as changes in the list occur.
