As used in this chapter:
"Board" means the board of land and natural resources.
"Cave" means any naturally occurring void, cavity, recess, or system of interconnected passages large enough for human entry, occurring beneath the surface of the earth or within a cliff or ledge, including the cave resources therein, whether or not an entrance exists or is natural or artificial, and that is of archaeological, geological, biological, or cultural significance. The term includes such forms as a lava tube, natural pit, sinkhole, underwater cave, or other feature that is an extension of the entrance.
"Cave life" means any living native plant, animal, fungus, or microorganism occurring naturally in caves or in cave entrances or entrance pits.
"Cave resource" means any material or substance occurring in caves, such as native animal life, native plant life, evidence of past human use over fifty years old, and tangible and intangible attributes associated with cultural traditions over fifty years old, paleontological deposits, sediments, minerals, speleogens, and speleothems. This includes historic properties as defined in chapter 6E.
"Commercial entry" means an activity undertaken to exhibit a cave for which compensation is received by any person for goods, services, or both, rendered to customers or participants in that use or activity. Commercial entry includes activities whose base of operations are outside the boundaries of the premises, or provide transportation to or from the premises. Any person receiving compensation in conjunction with a use or activity who seeks to qualify as noncommercial shall have the burden of establishing to the satisfaction of the department that the fee or charge is strictly a sharing of actual expenses of the use or activity. A not-for-profit organization that charges only a nominal fee to cover administrative costs and conducts a use or activity at a frequency or magnitude that does not significantly contribute to the degradation of the cave and its resources is not conducting a commercial entry.
