What is the difference between a forest ranger and a park ranger?

The job titles of a forest ranger and a park ranger are sometimes interchangeable. Both work to maintain safety for park guests and preserve the natural ecosystems of the park. In some places, park rangers are law enforcement officials who ensure that visitors follow conservation laws. In other areas, park rangers work as guides and provide educational services for park guests. While park ranger jobs are usually specific to state or national parks, forest rangers may operate in a broader range of settings, performing conservation duties in remote places for agencies not directly associated with parks or forests.
