Working Trees: Living Snow Fence. An Agrogorestry Practice.

摘要

Winter winds and blowing and drifting snow have the power to disrupt lives. Almost every year local radio stations announce school and road closures because of blowing and drifting snow. Sometimes miles of road will be closed when only a small segment has been drifted over. Blowing and drifting snow jeopardizes public safety and emergency services, interrupts businesses, increases road maintenance costs and causes livestock and wildlife mortality. Structural barriers, such as horizontal or vertical slatted snow fences, are a proven technique for reducing the impact of blowing and drifting snow. With an action similar to scattered rocks in a flowing stream, these barriers create eddy effects that alter wind speed and direction, causing snow to settle out. When roads are subject to recurring snow blockage, a more permanent, cost-effective solution is often desirable and needed.
