“Primary Distinguishing Characteristics of Level III Ecoregions of the Continental United States
The level III ecoregions used in CropMAP were revised March 1999. They were obtained from the National Health and Environmental Effects Research Laboratory U.S. Environmental Protection Agency. For a map of the level III ecosystems of the counterminous United States visit the EPA’s site at www.epa.gov/wed/pages/ecoregions/level_iii.htm”
there’s a 120!
6. SOUTHERN AND CENTRAL CALIFORNIA CHAPARRAL AND OAK WOODLANDS
The primary distinguishing characteristic of this ecoregion is its Mediterranean climate of hot dry summers and cool moist winters, and associated vegetative cover comprising mainly chaparral and oak woodlands; grasslands occur in some lower elevations and patches of pine are found at higher elevations. Most of the region consists of open low mountains or foothills, but there are areas of irregular plains in the south and near the border of the adjacent Central California Valley ecoregion. Much of this region is grazed by domestic livestock; very little land has been cultivated.
14. MOJAVE BASIN AND RANGE
This ecoregion contains scattered mountains which are generally lower than those of the Central Basin and Range. Potential natural vegetation in this region is predominantly creosote bush, as compared to the mostly saltbush-greasewood and Great Basin sagebrush of the ecoregion to the north, and creosote bush-bur sage with large patches of palo verde-cactus shrub and saguaro cactus in the Sonoran Basin and Range to the south. Most of this region is federally owned and there is relatively little grazing activity because of the lack of water and forage for livestock. Heavy use of off-road vehicles and motorcycles in some areas has caused severe wind and water erosion problems.
from Education of a Wandering Man, by Louis L’Amour
Over the years the terms applied to Wanderers have been confused until all meaning has been lost. To begin with, a bum was a local man who did not want to work. A tramp was a wanderer of the same kind, but a hobo was a wandering worker and essential to the nation’s economy.
In the days before the big combines it was the hobo who “shocked” the grain, picking up the bundles dropped by a binder and stacking them to be picked up by men on hayracks.
Many hoboes would start working the harvest in Texas and follow the ripening grain north through Oklahoma, Kansas, and Nebraska into the Dakotas. During harvest season, when the demand for farm labor was great, the freight trains permitted the hoboes to ride, as the railroads were to ship the harvested grain and it was in their interest to see that labor was provided.
