Ponderosa pine stands are fairly open with well-developed understories dominated by shrubs such as ninebark and bitterbrush (Purshia tridentata), and by Idaho fescue and bluebunch wheatgrass (Agropyron spicatum) (Elytrigia spicata of some authors). Less extensive coniferous series include one dominated by limber pine (Pinus flex//is). This type occurs on dry sites scattered across the east central and southeastern parts of the state and intermingles with the Douglas-fir series, with the pine occurringon the rockier, drier sites. It often occu- pies the loweredge ofthe forest zone and may border on the sagebrush-grass types as seen in Craters of the Moon National Monument.

This type is most extensive in thewestern and central partsof the sagebrushregion, where it alternates with big sagebrush, in a pattern determined by differences in effective soil depth. The understory grasses are similar to those in the big sagebrushtypes. The blacksagebrush ( nova) series is confined to the driest part of the sagebrush region, usually on shallow calcareous soils derived from limestone. The type is most extensive in the eastern partof the sagebrush region, where it borders thesalt-desert shrub. Bluebunch wheatgrassis the principal associated species. Theearly sagebrush(Artemisia Iongiloba) series is another low-growing type, occurringon shallow soils with strongly developedclaypans.
