Bioengineering materials installed in a riparian site
Soil Bioengineering is the term used to describe the use of plant material to arrest and prevent slope and stream bank failure and erosion. The roots and stems serve as structural and mechanical elements in a slope protection system. Live cuttings and rooted plants are embedded in the ground in various arrays to serve as soil reinforcements, hydraulic drains and barriers to earth movement. Once established, this living material effectively controls a number of stabilization and erosion control problems by binding the soil with its root system and creating a natural, vegetative cover. Bioengineered sites are self-repairing and have the advantage of blending with natural surroundings.
Ernst Conservation Seeds is an experienced producer of common and specialized live, soil bioengineering materials. We understand the unique needs of bioengineering site construction. Our material is grown, processed and delivered to minimize on-site installation labor and maximize survival and quick establishment.
LIVE MATERIAL NOTICE:
Bioengineering materials cut and ready for shipment to customers
The bioengineering material in the following paragraphs is dormant, live material. If the material cannot be installed immediately when it arrives at the job site, it must be properly stored. Place material out of direct sunlight in a cool, wet place, such as under straw or burlap. If packaged, open the pallets, boxes and plastic bags so the material can be thoroughly watered. Do not allow the material to dry out. Soaking before planting significantly increases survival and growth rate. Planting is best done during dormancy.
Note: For best survivability, the material should be planted during the dormant season, November 1st--April 30th. We do not guarantee any of our bioengineering material from May 1st--October 31st.
