Why "Herps of Texas"?
Herpetology is the study of reptiles and amphibians. "Herps" is a nickname for reptiles and amphibians; herpers are people interested in "herps". Since you are visiting this site, maybe you're a herper too!
County distribution maps were based on James Dixon's 1987 "Amphibians and Reptiles of Texas" (Texas A&M Press). Current distributions are based on Dixon's 2000 2nd edition and 2013 3rd edition of "Amphibians and Reptiles of Texas," as well as published range extensions through Dec 2012. In most cases, county records are based on actual museum voucher specimens; occasionally, in cases of sensitive species or protected areas, high quality photos are submitted and cataloged into museum collections as documentation of a given species' presence at a site.
The original Herps of Texas site was designed in 1993 by David Cannatella and Lori Bockstanz. Initial funding came from curriculum enhancement funds from the College of Natural Sciences of the University of Texas. Later, funds were provided by the Texas Memorial Museum; current funding is via the Biodiversity Collections within the Department of Integrative Biology. The re-design was done by Travis LaDuc and David Cannatella in 2009-2010.
