Here are just a few thoughts , so please feel free to add yours:

--- minimize impact the environment. Let`s respect nature by trying not to intentionally destroy habitat in the quest to find herps, such as prying rocks apart, debarking trees, tearing apart rotting logs, etc. ALLWAYS return rocks, logs, artificial cover (AC) and other forms of shelter as close as possible to their original positions after checking them . Do it for the herps and other critters that need their homes, and also for the fieldherpers that will later visit the place.

--- reduce the time and severity of handling wild herps. Try to minimize stress and diversion from their normal behavior.

--- pack out everything you brought in; don’t leave trash. Exept when creating board-lines of course; cause that`s habitat enhancement.

--- seek landowners’ permission prior to entering private property. Do not risk your life!

--- obey wildlife laws.

--- be an ambasador for fieldherping. Respond positively to questions from interested passers-by. They may not be herpers yet, but a good view of an interesting beast or a helpful answer may light a spark of interest. Your enthusiasm could start a lifetime's interest in reptiles and amphibians and a greater appreciation of wildlife and its conservation.

That`s all I have for know.
Happy herping!
