Erosion Blanket & Straw Mat
Erosion and straw blankets are used on dunes that have no vegetation or any type of foliage.
BENEFIT OF SERVICE
Erosion control blankets (or straw mats) are installed in order to prevent sand and soil shift and to promote vegetation establishment from plugs or seeds planted into the blankets.
Erosion control blankets can be used on a variety of terrains, from flat surfaces to steep dunes. They are a natural solution to both erosion control and vegetation growth, holding dune sand in place while the seeds and plugs take root.
HAZARD IF NOT APPLIED
If erosion control blankets are not applied to the face of the dune, the sand is viable to movement and will not be able to root any foliage. Dunes without a stabilization technique in place are susceptible to further erosion, which also harms your vegetation establishment efforts.
The site is prepared for straw mat installation. All debris, rocks, and roots are removed.
Where the site is steep, trenching is dug to anchor the matting and prevent any movement down the slope.
Straw blankets are then rolled from the top of the dune down to the bottom and staked into the sand/soil with wooden stakes. Straw wattles may also be installed in conjunction with erosion control blankets.
There are many different types of blankets: some are temporary and some can be permanent until removal is desired.
