The classification of habitats allows conservationists to  \nfocus on important habitats with defined risks that can be addressed by a suite of conservation measures. Atthe present time we have two mapping products that can provide insight for directing conservation efforts. First, we have a breed bird density map often referred to as the “Thunderstorm map”. The other products or series of products are derivatives ofthe thunderstorm map and use species experts’ identification of important habitats as they relate to seasonal or yearlong needs of populations.  \nFraming the geographical parameters, this primer will display the historic and current range of sage-grouse (Figure 1) Sage-grouse Management Zones (Figure 2), and the breeding bird density map (Figure 3) . Priority habitat maps are state and BLM products and we have provided links to those maps that are cut on state boundaries. At the present time state and federal biologists are beginning the process of edge matching priority habitat across state boundaries. This exercise is expected to be completed by mid-summer, 2012.  \nDistribution: Pre-settlement and Current  \nThe current and pre-settlement map of Greater sage-grouse was developed by state and federal sage-grouse experts in 2005 (Schroeder, et al., 2005) . The pre-settlement distribution of Greater sage-grouse is estimated to be 463,509 miles2. The estimate of current distribution is 258,075 miles2 or about 56% of the pre-settlement number.  \nFigure 1 Pre-settlement Potential Habitat and Current distribution (Greater Sage-grouse Comprehensive Conservation Strategy)  \nSAGE-GROUSE MAPPING AND PRIORITY HABITATS  \nNotes from the Lek  \nGreater Sage-grouse Conservation Primer Series Primer \\# 3  \nSage-grouse Management Zones  \nThe Greater Sage-grouse Comprehensive Conservation Strategy developed sage-grouse management zones determined by sage-grouse populations and sub-populations identified within seven floristic provinces. Floristic provinces (identified by Connelly et al. 2004) were used to delineate Management Zones because they reflect ecological and biological issues and similarities, not political boundaries. In addition, the vegetation communities found in the floristic provinces, as well as the management challenges, within a Management Zones are similar and sage-grouse and their habitats are likely responding similarly to environmental factors and management actions.  \nFigure 2. Sage-grouse Management Zones with Populations and sub-populations.  \nBreeding Sage-grouse Density Map  \nThe BLM funded and coordinated the project and worked with the Western Association of Fish and Wildlife Agencies, the U.S. Fish and Wildlife Service, the University of Montana and The Nature Conservancy to make it happen.  \nThe range-wide breeding sage-grouse density map was developed by Doherty, et al. in 2010. The data used to generate the map were collected in the states during lek counts. Lek counts are conducted to measure trends in populations.  \nSAGE-GROUSE MAPPING AND PRIORITY HABITATS  \nNotes from the Lek  \nGreater Sage-grouse Conservation Primer Series Primer \\# 3  \nFigure 3.
