Herping is the act of searching for amphibians or reptiles. The term, often used by professional and amateur herpetologists, comes from the word herp, which comes from the same Greek root as herpetology, herpet-, meaning creeping.
Field herping (looking for reptiles and amphibians in the wild) is an enjoyable activity that should give you a broader understanding how these species live and interact with their environment. In most cases, herping involves watching, photographing or catch and release. I'm not averse to occasionally keeping specimens for native breeding projects, but be aware of your local laws and don't overcollect.
