Mitigation Site Soil Characteristics And The Effects Of Inoculation, Nursery Fertilizer Practices And Irrigation On Survival And Growth Of Mesquite (Prosopis Glandulosa) In The Coachella Valley, California, David A. Bainbridge, Marcelle M. Darby
David A Bainbridge
Prosopis glandulosa var. torreyana (mesquite, honey mesquite) is a small to medium sized leguminous tree that was once common in the low desert of California. Widespread destruction of mesquite woodlands in the Coachella Valley of southern California for fuel wood, agricultural and urban development, and urbanization has reduced once vast stands to isolated remnants. The rerouting and widening of Highway 86 in the Coachella Valley was a typical example of ongoing mesquite woodland removal. Despite the recognized need for mitigation, relatively little information on mesquite establishment in California is available. This research explored mesquite establishment by replanting on an abandoned …

Recreating Mesquite Mounds (Nebkas) In The Colorado Desert, David A. Bainbridge
David A Bainbridge
Accretion dunes or mounds (also known as nebkas or nebkhas) are formed when plants capture and then are partially buried in wind-blown sand. In the San Felipe drainage in the western Colorado Desert, mesquite (Prosopis glandulosa Torrey var. torreyana (L. D. Benson) M. C. Johnston)) forms dunes up to 5 m high. These are ecologically important for both ecosystem structure (primarily habitat) and function (soil accumulation, moisture retention and nutrient cycling). The widening of California state highway 86 damaged and removed several mesquite mounds and the California Department of Transportation asked us to explore techniques for recreating them to reduce …

The Hudson’S Bay Company Brigades Of 1832-33 And The Malaria Epidemic In California, David A. Bainbridge
David A Bainbridge
The ecological and cultural impacts of the Hudson’s Bay Company fur brigades to California were long term and important, but the expedition of 1832-33 caused a catastrophe by introducing the intermittent fever. The “intermittent fever” led to mortality rates from 50-90 percent or more, and it is likely more than 30,000 people died from the fever in the affected areas of California.
Buried Clay Pipe Irrigation, David A. Bainbridge
Buried Clay Pipe Irrigation, David A. Bainbridge
David A Bainbridge
The buried clay pipe method of irrigation is one of the most efficient systems known and is ideal for gardeners and small farmers. Buried clay pipe irrigation uses a buried, unglazed clay pipe filled with water to provide controlled irrigation to plants as the water seeps out through the clay wall at a rate that is influenced by the plant's water use. It has been used for more than one hundred years.This auto-regulation leads to very high efficiency--considerably better than drip irrigation and many times better than conventional surface irrigation. This also reduces weeds, increases yields, and can speed maturity …

Acorn Use As Food, David A. Bainbridge
Acorn Use As Food, David A. Bainbridge
David A Bainbridge
The acorns from oaks (Quercus) and tan oaks (Lithocarpus) have been used as food for many thousands of years. They occur in the archaeological record of the early town sites in the Zagros Mountains, at Catal Hüyük (6000 BC), and oak trees were carefully inventoried by the Assyrians during the reign of Sargon II. In Europe, Asia, North Africa, the Mid-East, and North America, acorns were once a staple food. They are still a commercial food crop in several countries. Acorns are still harvested and used in several areas of the United States, most notably Southern Arizona and California. There …
