About this layer

Surface management areas show the agency or organisation recorded as managing the land surface. Start here to identify whose guidance to check. Surface management can differ from mineral ownership and does not settle access by itself.

What it is for

Turn on the relevant layers together and read their legends and notes. Check current conditions with the land manager before planning a visit.

Limits

An unshaded area is not automatically available for detecting. Different permissions and restrictions can overlap.
