Framework / Assessment Criteria and Indicators of Sustainable Rangeland Management Summary This indicator measures changes in ownership, ownership stability, and how the land is being used (e.g., ranging from public to private ownership, production agriculture to residential lots). It will measure how quickly rangelands are turning over (i.e., converting from one owner to another or from one use to another). It is important to sustainability because conversion of open rangeland to housing developments, for example, have an effect on many aspects of rangelands (e.g., loss of open space, habitat fragmentation, noxious weeds) as well as diminishing future options for the land.
