For the amature herpetologist, there are many Herpetology Societies around the country. Such as the San Diego Herpetological Society, Phoenix Herpetological Society, Texas Herpetological Society, East Texas Herpetological Society and the Austin Herpetological Society.

As reptiles become more popular, the field moves from a "catch your own wild reptile pets" to a "buy captive bred reptiles" policy. Most states now have laws regulating herping, for example many require some sort of a hunting or fishing license if you want to collect herps. They may also have rules on time of the year and number of herps that can be collected.
