Definitions


Term	Definition	Comments
Present in Park	Species occurrence in park is documented and assumed to be extant.	Extremely high confidence that the species occurs in the park for all or part of the year. Evidence, in the form of a current, verifiable reference, voucher or observation, readily available.
Probably Present	Documented occurrences of the species in the park and/or in the adjoining region of the park give reason to suspect that it probably occurs within the park.	Very high confidence that the species occurs in the park. Evidence may exist in NPSpecies, but may not be considered current or reliable enough to elevate the status to Present in Park. Efforts should be made to obtain current, verifiable evidence to elevate the status to “Present in Park.” If reasonable efforts to obtain current, verifiable evidence are unsuccessful, then the Occurrence should be changed to Unconfirmed or Not in Park, as applicable.
Unconfirmed	Attributed to the park based on weak ("unconfirmed record") or no evidence, giving minimal indication of the species' occurrence in the park.	Verifiable evidence is not considered sufficient enough to elevate the status to “Probably Present,” nor current enough to elevate the status to “Present in Park.” Efforts should be made to obtain current, verifiable evidence in NPSpecies to elevate the occurrence value to “Present in Park.” If reasonable efforts to obtain current, verifiable evidence are unsuccessful, status should be changed to Not Present.
Not Present	Species is not known to occur in park. Species may have occurred in the park historically, is currently known to occur in areas adjacent to the park, or is a potential long-distance invader (e.g., zebra mussels, other invasive exotics). Designation can also be used for T&E or other high-interest species whose identified range encompasses the park, but that are confirmed not present in the park.
Species in Review	These species records are provisional and are undergoing additional review.
