4. Geocache placements do not damage, deface or destroy public or private property. Caches are placed so that the surrounding environment, whether natural or human-made, is safe from intentional or unintentional harm. Property must not be damaged or altered to provide a hiding place, clue, or means of logging a find.
5. Wildlife and the natural environment are not harmed in the pursuit of geocaching. Geocaches are placed so that plant and animal life are safe from both intentional and unintentional harm. In some regions geocaching activity may need to cease for portions of the year due to sensitivity of some species.
