A forest ranger is a professional who is responsible for the protection and conservation of forests. They are also responsible for managing recreational activities in the forest. The term 'forest ranger' can be broken down into three parts: ELK (3 letters), DEER (4 letters), and WAPITI (6 letters). ELK refers to the large DEER species, DEER is a type of hoofed mammal, and WAPITI is another name for ELK. All three of these animals are commonly found in forests and are managed by forest rangers.
