The four National Park Authority rangers have three main functions:
- They are a visible presence in National Park and surrounding areas acting as a first point of contact
- They work to increase the understanding of visitors and local people of the things that make the National Park special, including its culture, landscape and wildlife
- They help to develop local community projects that conserve or enhance the special qualities of the National Park and improve access to it.
There are many other rangers and volunteer rangers in the New Forest National Park including those working for the Forestry Commission, National Trust and Hampshire County Council.
