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.

J. Keys to Successful Streambank Soil Bioengineering

  • Inventory: Characterizing existing conditions
  • Establishing objectives to drive your project planning
  • Selecting appropriate species for the site
  • Season of planting: Finding optimum conditions for best establishment
  • Proper handling to survive transplanting and planting materials
