The Wilderness is being monitored for clean air, with special  concern for visibility, water quality and vegetation. Sulfur compounds produce a haze reducing visibility, an acidification of streams and a leaching of nutrients from the soil, and ozone creates visible injury to plant leaves reducing plant growth. Pollutants are created by many sources over a large geographic region.
