Logs and downed trees embedded in stream banks deflect and slow currents, collect sediments and sort gravels, encourage healthy stream meandering within the floodplain, stabilize banks and create critical fish and insect habitat along stream edges.
A variety of native trees and shrubs planted along naturally contoured banks stabilizes soils, shades and cools water, catches debris during high flows and improves habitat for fish, birds and animals.
"Bio logs," "coir logs," "vegetated soil lifts" and other bank-stabilizing tools made of organic materials can be used to protect banks without hardening them with rock. These "soft" banks slow the force of floodwaters down instead of speeding it up and causing more problems downstream.
Large wood and rocks placed within the floodplain create "roughness" that slows flow velocities, collects sediments for healthy soils, and provides habitat for fish and insects.
