The Lahontan uplands are restricted to the highest elevations of the mountains ranges within the Lahontan salt dortmund jersey shrub basin. However, continuous woodland is not as prevalent on the mountains of central Nevada as in other woodland ecoregions, such as ecoregions 13d and 13q. Pinyon-juniper grows only sparsely through the shrub layer due to combined effects of past fire, logging, and local climate factors, including lack of summer rain and the pattern of winter cold air inversions. Less shadscale and fewer associated shrubs surround these playas than in other, lower more arid ecoregions in the west, including the Lahontan salt shrub ecoregion and the Tonopah Basin ecoregion. As a result, shrub cover is sparse in contrast to other sagebrush-covered ecoregions in Nevada. Similar to basins further north, shadscale and associated arid land shrubs cover broad rolling valleys, hills, and alluvial fans. In addition to shadscale, other salt-tolerant shrubs, such as Shockley’s desert-thorn and Bailey greasewood, cover the lower basin slopes. Slopes vary in elevation from 6,400 to 8,800 feet (2,000 to 2,700 m) and are covered in sagebrush, grasses, and scattered Utah juniper. Hills, alluvial fans, and low mountains comprise the Lahontan sagebrush slopes ecoregion.
Areas of black and Wyoming big sagebrush grade upward into mountain big sagebrush and curlleaf mountain-mahogany, which straddles the transition between this mid-elevation brushland and the mountain brush zone of the higher Central Nevada Bald Mountains. These barren-looking mountains are covered instead by dense mountain brush that is dominated by mountain big sagebrush, serviceberry, snowberry, and low sagebrush. The Upper Humboldt Plains ecoregion is an area of rolling plains punctuated by occasional buttes and low mountains. Grazing is the major land use, though there is some agriculture near the Humboldt River. Although there is a direct connection to the south to the Mojave Desert, winters are cold enough in this ecoregion to discourage the northward dispersal of Mojavean species into the Lahontan Basin. As with so many colorful characters who lived during the heyday of the American Wild West, there are a lot of uncertainties about the life of Tom Horn.
Suicide can be a risk, such as with singer Kurt Cobain (1967-1994), who took his life while dealing with biploar disorder. This could have been the true six string adjusting referred to by Tommy Johnson, the real person who claimed he had sold his soul to the devil, as told by his brother LeDell. This ecoregion tends to have lower species diversity than other sagebrush ecoregions, because of its aridity and isolation from more species-rich areas. Where extensive woodlands do exist, understory diversity tends to be very low, especially in closed canopy areas. Low sagebrush is common in extensive areas of shallow, stony soil, as are cool season grasses, such as bluebunch wheatgrass, Idaho fescue, and Sandberg bluegrass. Wyoming big sagebrush and associated grasses are common on the flatter areas, and black sagebrush dominates on the volcanic hills and alluvial fans. However, as in the warmer Lahontan Basin to the west, lightning fires are common and a post-fire monoculture of cheatgrass tends to replace the native grasses and shrubs. However, unlike the Lahontan salt shrub basin and Upper Lahontan basin, the shrubs often co-dominate in highly diverse mosaics. Scattered groves of curlleaf mountain-mahogany and aspen in moister microsites grow above the shrub layer.
Even in alluvial soils, root growth may be limited by a hardpan or caliche layer formed by carbonates leaching through the soil and accumulating. Tsunamis can be dozens of feet tall, but in deep water, the waves may not be apparent on the surface. A few scattered limber or bristlecone pines grow on ranges that exceed 10,000 feet (3,000 m). The basins and semi-arid uplands of the Carbonate Sagebrush Valleys surround the carbonate ranges of eastern Nevada. Alluvial fans spilling from the surrounding mountain ranges fill the valleys, often leaving little intervening flat ground. They contrast with the High-elevation Carbonate Mountains to the east, where the mountain brush zone is too narrow to be mapped as a separate ecoregion. The Central Nevada Bald Mountains are dry and mostly treeless. The low hills and mountains of the Lahontan Basin experience frequent summer lightning and fire. The combination of summer moisture and a limestone or dolomite substrate affects regional vegetation, particularly in terms of species dominance and elevational distribution. The grass understory grades from a dominance of cool season grasses, such as bluebunch wheatgrass, in the north, to warm season grasses, such as blue grama (an indicator of summer rainfall) in the south.
