The following
tables should not be considered a definitive list of the
vertebrate species occurring on the INL.
Although all of the abundant and common species should be
included, some of the less commonly occurring species may have
been missed. Not all habitats on the INL have been
surveyed with the same intensity. Therefore, the number
of vertebrate species observed on the INL is likely to
increase as field efforts in some of the lesser studied
habitats intensify.
