Design Tips for Soil Bioengineering
Soil bioengineering is an interdisciplinary approach to environmental restoration which involves the incorporation of biological systems with engineering principles in order to restore soil and thereby protect water resources. It is the only environmentally sound technique for restoration of degrading water edges (streambanks, shorelines, wetlands etc.). These techniques believe in the ability of mature vegetation to resist erosion forces. Natural biodegradable products are used to provide the needed protection until establishment of mature vegetation. These methods not only provide strong, sustainable, aesthetically pleasing water edges, but also provide habitats for aquatic & terrestrial wildlife and filter run off water.

Advantages of Soil Bioengineering ?
- Sustain a balanced ecosystem. Nourish naturally strong, healthy environment.
- Reduce heat reflection. Provide aesthetically pleasing applications.
- Increase infiltration. Filter sediment and improve water quality.
- Support recreational activities. Accommodate quality habitats for wildlife and fish.
- Convey peace of mind for all of us. Create environment to rest and reduce human stress.
Disadvantages of hard armor methods
- Do not support plant growth.
- No shade, increase water temperatures.
- Fish kills during summer due to low Dissolved Oxygen.
- Do not create habitats for wildlife.
- No litter for primary production.
- Results in unbalanced ecosystem.
- No evidence of significant life
Proper Bioengineering
Economical, strong, durable yet biodegradable coir (coconut fiber) products play a significant role in these techniques. Coir products not only provide strong support, but also provide mulch (upon biodegradation) that improve soil conditions for healthy plant growth.
Use coir products to improve hard armor method
Use coir products such coir pillows, coir plant beds, coir wattles, over rocks and rock gabions to provide a medium for plant growth.
