STRAW BLANKET

​

DEFINITION AND PURPOSE: A straw blanket is a protective blanket of straw designed to protect soil from the impact of precipitation and overland flow, and retain moisture to facilitate establishment of vegetation. Erosion control blankets are sometimes referred to as Rolled Erosion Control Products (RECPs).

 

APPROPRIATE APPLICATIONS: Typically installed on seeded areas for temporary use, and in landscaped areas for permanent use.

 

 

CONDITIONS FOR EFFECTIVE USE: Several factors, such as soil conditions, steepness and length of slope, depth of flow, runoff velocities, and time required to establish desired vegetation influence the choice of product. Different products are available for a variety of uses: Netting-synthetic or natural fiber mesh installed over disturbed areas to hold organic mulch and/or seed in place, biodegradable erosion control blanket-natural fiber blanket held together by netting to provide temporary erosion protection on slopes and channels, and permanent erosion control blanket-synthetic blanket material which provides permanent erosion control on slopes and channels with increased water flow velocities.
