Originally published on May 15, 1996, by the Colorado Herpetological Society, these tables contain the most current updates of the county record tables. (Material originally compiled, and periodic updates furnished, by Lauren J. Livo. 1999 revision published by the Colorado Division of Wildlife, Denver, Colorado.)


The tables in this document indicate whether a county record exists for any native reptile or amphibian in Colorado, and a bibliographic entry for any records that do exist. You can search the tables by County, or by the scientific or common name for any species.

If an asterisk ( '*' ) appears in the references column, this indicates that, while the species has not been documented for the county, it may occur there (Reichard et al. 1996).

If a pound sign ( '#' ) appears in the references column, this indicates that, while at least one of the subspecies has not been documented for the county, two possible subscpecies of the same species may occur in the county.

If the reference is surrounded by parentheses, the record may represent introduced individuals.

The tables also normally omit records for non-native (introduced) amphibians and reptiles except for those of the bullfrog, Rana catesbeiana, which has populations established in many localities in the state.


Included in this document are the following pages:
Four indexes and a map of all the Colorado Counties.
The native species pages are indexed alphabetically by scientific and by common name, and indexed taxonomically by families. The County pages are indexed alphabetically.
One page for each of the 67 species of reptiles and amphibians known to be native to Colorado.
Each of these pages contain a brief description of the species, any recognized subspecies, and a table of all the Counties of Colorado, indicating whether that species has been documented as occurring in the County, or is expected to occur there. Where a published County record exists, a link is provided to the bibliography page. Expected but undocumented occurrence is indicated by an asterisk (*). A pound sign (#) indicates that more than one subspecies is known or expected for the county.
One page for each of the 63 Counties in the State of Colorado.
Each of these pages contains tables of all the species of Amphibians (18), Turtles (5), Lizards (18), and Snakes (25) known to be native to Colorado. Documented occurrence of a species is indicated by a reference code, while expected but undocumented occurrence is indicated by an asterisk (*). A pound sign (#) indicates that more than one subspecies is known or expected for the county.
A separate page contains references for all County documentation records.

In addition to cited references, these tables indicate where native amphibians and reptiles may be found, but which are not currently documented. This information is based on the paper "Herpetological Microbiogeography of Colorado I: Numerical Summary" (Duncan, et al, 1996), also included here.
