Streambank & Gully Erosion Control

Riparian Management for Hill Country farms

An option is poplar and willow tree planting on outer bends of river channels and at the foot of erosion prone slopes and up hillslope watercourses.
Wide spacings along straight river reaches will also protect scarce valley faults from collapse into river channels.

Tunnel Gully Erosion

Tunnel gully erosion is a farm management problem creating hazards for both farm staff and stock.
It is best controlled by planting poplar or willow poles into or beside tunnel gully holes.
Poles may need additional length to keep shoot growth out of reach of stock.
