|8:30||Greetings and scope of workshop
A. Principles of Streambank Bioengineering• Basic principles of using plants as the main structural component to reduce erosion on streambanks • Limitations to vegetation thru streambank characteristics, bank geometry, site preparation, and vegetative types • Advantages of streambank bioengineering
B. General Riparian Vegetation Concepts for Stabilization, Shade, Water Quality and Fish/Wildlife Habitat • Vegetation and moisture gradients affect plant species composition • Structure of plant communities • Plant succession within the riparian area • Planting zones: toe, bank, overbank, transitional and upland.
C. Riparian Plant Propagation
• Propagation of herbaceous and woody riparian plants: planting stock types, hardwood propagation, planting recommendations, planting methods, containerized plants, establishment success and planting herbaceous wetland plants.
G. Using Streambank Erosion Control Treatments in Riparian Planting Zones
1. Toe Zone Bioengineering Treatments • Fascine• Coir log• Brush revetment
• Brush box
• Root wads
2. Bank Zone Bioengineering Treatments
• Brush mattress
• Brush layer
• Vertical bundles
• Vegetated geogrid
3. Overbank Zone Bioengineering Treatments
• Clump plantings
• Erosion control fabric
• Brush trench
• Containerized plants
4. Bioengineering Treatments and Rock
• Brush spurs
• Vertical bundles behind rock
• Brush mattress with rock toe
• Brush layer with rock toe
