* The former Category 1, 2, & 3 classifications no longer exist. ^a SC1 definition - Native species whose status is questioned due to suspected problems with abundance or distribution. Many of these species occupy habitats that were once fairly common. ^b SC2 definition - Native species whose status is questioned due to limited and/or inconclusive historical citations. ^c Peripheral - Native species with small or unknown populations whose breeding distribution or reproduction ability within the state is often severely limited by lack of suitable habitat and/or climate. These species have not had an appreciably more widespread distribution in the recent past.
