The species listed here are assumed to be 'present in park' and have been reviewed. Evidence, in the form of a current, verifiable reference, voucher or observation, is included in the NPSpecies data system or is readily available. Those species marked with an asterisk have the designation of 'probably present,' and efforts are underway to obtain current, verifiable evidence to elevate the status to 'present in park.'
