Slotted Drainage Pipe For Sub-Irrigation, David A. Bainbridge
Slotted Drainage Pipe For Sub-Irrigation, David A. Bainbridge
David A Bainbridge
Subirrigation with drainage pipe was effective for planting a windbreak in the Mojave Desert. The pipe was refilled periodically with a water truck. Survival was very good.
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
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
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 …
Infiltrometers For Restoration Site Evaluation, David A. Bainbridge
Infiltrometers For Restoration Site Evaluation, David A. Bainbridge
David A Bainbridge
Infiltration is a key factor in site disturbance and recovery as it determines soil moisture into the soil. Field evaluation can be done with an infiltrometer or sprinkling infiltrometer. Low cost field tested methods include: double ring, single ring and microsprinkler infiltrometers.
Site Assessment For Environmental Restoration, David A. Bainbridge
Site Assessment For Environmental Restoration, David A. Bainbridge
David A Bainbridge
Restoring degraded desert ecosystems is challenging but it can be done. The first key step is understanding the site history and understanding the disturbance and current site conditions. With this information the appropriate steps can be taken to improve the site ecosystem function and structure.
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 …
Anatomy, Physiology And Psychology Of Desert Destruction, David A. Bainbridge
Anatomy, Physiology And Psychology Of Desert Destruction, David A. Bainbridge
David A Bainbridge
Off road vehicle damage continues to expand in the California deserts. This 2004 presentation explores the causes and possible methods for reducing destruction. Protecting and restoring the desert is not a technical problem but an economic/accounting problem.
Self Reliant Agriculture For Arid Lands, David A. Bainbridge
Self Reliant Agriculture For Arid Lands, David A. Bainbridge
David A Bainbridge
More than a billion people face the challenge of supporting themselves in the world's arid lands. Much can be improved by refining and adopting the best traditional practices and crops from around the world. The lessons learned can also help develop new and improved agronomic practices and crops.
Revegetating Desert Plant Communities, David A. Bainbridge
Revegetating Desert Plant Communities, David A. Bainbridge
David A Bainbridge
Desert revegetation is possible but not easy. Careful attention to plant production (root:shoot), site prep, planting, irrigation and aftercare can lead to good survival even under extreme desert conditions. Cost per survivor is a critical consideration.
Soil Pitting For Revegetation, David A. Bainbridge
Soil Pitting For Revegetation, David A. Bainbridge
David A Bainbridge
Soil pitting provides many benefits in ecological restoration of degraded lands. The pits capture rainwater, trap seeds and soil symbionts and protect seedlings from windblast.
Soil Treatment For Restoration Projects, David A. Bainbridge
Soil Treatment For Restoration Projects, David A. Bainbridge
David A Bainbridge
Soil treatment is a critical step in restoration projects. When soil problems are ignored restoration projects fail. Erosion, compaction, limited infiltration and other problems can make a site very different from its historic function and structure. Treatment can be done with equipment or by hand and will greatly improve chances for success.
