Which of the following is a type of park ranger specialization?

Law enforcement ranger is a recognized specialization within park ranger roles. This specialization focuses on ensuring the safety and security of park visitors, protecting park resources, and enforcing laws and regulations within park boundaries. Law enforcement rangers undergo specific training to handle situations that require law enforcement skills, such as responding to emergencies, investigating crimes, and working in collaboration with local and federal law enforcement agencies.

The other specializations mentioned do not have the same established function within the park ranger profession. Wildlife photography may be a hobby or additional skill for some park rangers, but it is not an official specialization associated with park management or visitor safety. Environmental economics is relevant to park management but typically falls under administrative or policy-making roles rather than on-the-ground ranger duties. Marketing does not align with the core responsibilities of park rangers, which center on conservation, visitor services, and law enforcement.
