This data does not supercede the responsibility to make referrals regarding your planned work to tenure holders who may potentially be affected.  

The NRB layer is a starting point for the timber planners to meet with the Ranchers to discuss the actual on-the-ground NRBs and mitigation strategies required. As such, operates as a flag.

Natural Range Barriers defined in the MoF “Definition of Forestry Terms” as:

	A river, rock face, dense timber or any other naturally occurring that stops or significantly impedes livestock movement to or from an adjacent area.

Vegetation barriers (and water, to a degree) are mapped with variable accuracy and precision. Their locations and effectiveness are subjective based on client experience and herd characteristics (eg. A rancher who gets a new animals (bull) or even a new herd each year might see the same NRB provide a varying level of effectiveness). In the above definition, the words “significantly impedes” acknowledges that variability. 

NRBs, both in the actual world and also as mapped features are very much in flux. We likely don’t have up-to-date or complete data for each District, and there is much change with treed barriers because of MPB harvesting.


Note: Legacy data included in this shapefile may not have a Risk rating attached to it.
