A ranger is someone whose job involves protecting and managing wilderness areas like forests, parks, or nature preserves. Park rangers patrol trails, teach visitors about wildlife and plants, help people who get lost or injured, and make sure campers follow safety rules. They might also fight wildfires, track animal populations, or rescue hikers in trouble.

Rangers range across their territory, covering miles of wilderness on foot, horseback, or in trucks. They need to know their land intimately: which trails lead where, where animals gather, and how weather patterns change through the seasons.

In history, rangers were soldiers skilled at wilderness fighting and scouting. The Texas Rangers were a law enforcement group formed in 1823, while Rogers' Rangers fought in the French and Indian War. These rangers moved quickly through rough country and knew how to survive in the wild.

The term also appears in fiction. The Lone Ranger was a masked hero of old radio shows and TV westerns. In The Lord of the Rings, Aragorn is a ranger who protects travelers in the wilderness.

Whether modern or historical, rangers share common traits: toughness, knowledge of the outdoors, and dedication to protecting something valuable, whether it's people, land, or both.
