Wilderness character is a holistic concept based on the interaction of (1) biophysical environments primarily primarily free from modern human manipulation and impact, (2) personal experiences in natural environments relatively free from the encumbrances and signs of modern society, and (3) symbolic meanings of humility, restraint, and interdependence that inspire human connection with nature. Because personal experiences and symbolic meanings are intangible and may differ from person-to-person, further defining these components of wilderness character has not occured.
The agencies that manage wilderness, including the NPS, have defined the 5 tangible qualities of wilderness character:
- NATURAL - Ecological systems are substantially free from the effects of modern civilization.
- UNTRAMMELED - Wilderness is essentially unhindered and free from the intentional actions of modern human control or manipulation.
- UNDEVELOPED - Wilderness is essentially without permanent improvements or the sights and sounds of modern human occupation.
- OPPORTUNITIES FOR SOLITUDE OR PRIMITIVE & UNCONFINED RECREATION - Wilderness provides opportunities for solitude or a primitive and unconfined type of recreation.
- OTHER FEATURES OF VALUE* - Wilderness may also contain ecological, geological, or other features of scientific, educational, scenic, or historical value.
