Description 14 IS UTAH SAHARA BOUND? or meadow lands were spread out before us like a green carpet richly clothed with a variety of grasses, and possessing a soil both black, rich and quickâ€" being a mixture of sand, gravel and clayey loam, and the decayed vegetation of ages. It is everywhere moistened with springs and would produce potatoes, vegetables and small grains in abundance without watering. "The surrounding hills are abrupt, but rounded off, presenting a variety of beauteous landscapes, and everywhere richly clothed with the choicest kind of bunch grass and bordered in their higher eminences with cedar and nut pine sufficient for fuel." Contrast now Pratt's21 account of the Mountain Meadows of 1851 with Bancroft's3 vivid description of the same spot as it appeared March 23, 1877, when Lee was executed at the scene of his terrible crime. "Over that spot," says Bancroft, "the curse of the Almighty seemed to have fallen. The luxuriant herbage that clothed it twenty years before had disappeared; the springs were dry and wasted, and now there was neither grass nor any green thing save here and there a copse of sagebrush or scrub oak that served but to make its desolation still more desolate." Critical research methods applied to this area have shown that the hillside grasslands as well as the meadow bottoms have in one generation of man seen a complete succession from grassy to shrubby types, and that the latter in turn are now rapidly being invaded by juniper. Population studies show that junipers, once confined to the "higher eminences," have in four score years increased their domain more than six times. The most disturbing fact of the juniper succession is that grass can never again assume dominance on these slopes unless man removes the junipers. Precipitation is not sufficient here to support both junipers'and grass and competition certainly would favor the junipers. Unfortunately, the situation at the Mountain Meadows does not represent an isolated case of alarming juniper invasion of former grassland types; on the contrary, this phenomenon is generally widespread over the foothills throughout the entire Basin. The study of trends26 of succession in the lowland valley types of the desert has involved careful consideration of the following pertinent facts for each of the important plant communities; 1. Age classes of the population. 2. Reproduction status. 3. Palatability of each major species to livestock. 4. Vigor. 5. Mortality. 6. Root habits and soil preferences. Only summary statements of these results as they point to the cause of the amazing succession in desert plant types are possible: (1) Grass, white sage, spiny hop sage and other highly palatable vegetation show serious depletion and high mortality and have little or no reproduction. The state of their vitality is low. Their population age groups are predominantly oldâ€"above 30 years. %
