Forest range
A forest range is a term used to define administrative regions containing one or more (usually) demarcated and (usually) protected or resource-managed forests. The term was in use in British India, and hence India, Pakistan and Bangladesh use this term for administrative purposes.
In India
In India, the combined forests in a forest division are completely divided into non-overlapping forest ranges for the purpose of administration and coordination, in an analogous form of dividing the political area of a subdivision into blocks. Alignment of the ranges to political boundaries is not necessary, as forests often overlap political boundaries - but one range cannot span more than one state.
A forest range may be broken up into one or more beats or sections, under Forest Beat Officers or Forest Section Officers respectively.
Each range controls the protected areas and managed resources under its jurisdiction, and is presided over by a Forest Range Officer, appointed from the corresponding State Forest Service.
