Abstract

A general ecological description of Chaco Canyon National monument is presented. Plant associations are named and specific ecological factors limiting the distribution of the herpetozoa are described.

Field work at Chaco Canyon was carried out from 17 June to 1 September 1968. Data were gathered on the composition and distribution of plat association, reptiles, and amphibians. Field data gathered include plant and herpesian associates, physiographic areas, exposure, and substrata.

Distribution of plant associations was found to be correlated with the physiography. Distribution of lizards and amphibians was found to be correlated with substrate. Ecological factors which dictate the distribution of snakes were not found, but are suggested to be behavioral and temporal. Distribution of plant and herpesian species was found to be independent.

Relative abundance and dominance of lizards was considered, and data on breeding activity in lizards is presented.
