Erosion Control Blankets (size: 8 ½ x 112ft, 952 sq ft, 105 sq yards)
Erosion Control Blankets are used to cover bare or newly planted soil, and are effective in minimizing the erosive effect of rainfall. Their use stabilizes the soil to protect new seed and plantings and reduces sediment during storm water run-off events.
Erosion Control Blankets are effective for soil stabilization on steep to moderate slopes, new landscaped areas, and drainage swales and ditches that are to be planted or seeded. Additionally:
- They increase water infiltration into the soil.
- When used with a seed mix, they protect the mix from being eroded during heavy rainfall or wind.
- They increase the retention of soil moisture to promote seed germination.
- Most importantly, they reduce soil erosion.
When properly installed and maintained Erosion Control Blankets provide excellent short and long-term erosion control. Proper soil surface preparation is critical to the effectiveness of the installation:
- All rocks, clods, debris, and vegetation should be removed to ensure full contact between the blanket and the soil surface.
- The blanket should be anchored to the soil using 6” or 8” metal wire staples. The staples should be driven through the blanket and into the soil, flush with the soil surface.
- Erosion Control Blankets should not be used where final vegetation will be mowed, because material and staples may be caught in the mowers. Native Seed Mixes should be sown before blanket installation.

Blankets are available with either a 100% biodegradable weave jute net or photo-degradable polypropylene netting We recommend biodegradable weave jute net blankets in all wetland and adjacent areas, or any environmentally sensitive area because animals can get tangled and trapped in the plastic (polypropylene) netting, which has fixed joints at the 4 corners of each net opening, whereas the biodegradable top & bottom weave jute net is more flexible and forgiving.
|ECS-1B — 100% agricultural straw fibers sewn to a biodegradable weaved jute net on one side. Suitable for slopes 3:1 or less, for low-flow to moderate-flow runoff conditions. Also available with a polyethylene photo-degradable net (ECS1). The ECS-1B has a functional longevity of approximately 12 months, but will vary depending on soil and climatic conditions.|
|ECS-2B — 100% agricultural straw fibers sewn to a biodegradable weave jute net on both top and bottom. Suitable for slopes 2:1 or less and low to medium flow channels. The ECS-2B has a functional longevity of approximately 12 months, but will vary depending on soil and climatic conditions.|
|ECS-2 is made with uniformly distributed 100% agricultural straw and two polypropylene nets securely sewn together with photo-degradable thread. The ECS-2 has functional longevity of approximately 12 months, but will vary depending on soil and climatic conditions, and is suitable for slopes 2:1 or less and low to medium flow channels.|
|ECSC-2B — 70% agricultural straw, 30% coconut fiber blanket sewn to a biodegradable weaved jute net on both top and bottom. For use on 2:1 — 1:1 slopes with moderate-heavy runoff conditions. Handles steep slope rehabilitation, drought area re-vegetation, long slope, cut and fill, mine land, landfill reclamation, bridge abutments, ski runs, and channel shoulders. Functional longevity 18 months, but will vary depending on soil and climatic conditions.

|The ECSC-2 is made with uniformly distributed 70% agricultural straw, 30% coconut fiber and two polypropylene nets securely sewn together with degradable thread. The ECSC-2 has functional longevity of approximately 24 months, but will vary depending on soil and climatic conditions, and is suitable for slopes 2:1 to 1:1 and low to medium flow channels.|
|ECC-2B — 100% coconut fiber with biodegradable weaved jute net on both sides. For use on 1:1 slopes. For use as a liner in channels with high velocity, intermittent flows; at the bottom of center runs on grassed waterways; in drainage ditches; and on stream banks on steep slopes and other harsh sites. Functional longevity 24 months, but will vary depending on soil and climatic conditions.|
|The ECC-2 is made with uniformly distributed 100% coconut fiber and two polypropylene nets securely sewn together with UV stabilized thread. The ECC-2 has functional longevity of approximately 36 months, but will vary depending on soil and climatic conditions, and is suitable for slopes 1:1 and medium to high flow channels.|
Coir Mats (size: 6 ½ x 167ft, 1085 sq ft, 120 sq yards)
Long-lived, high-strength, 100% coconut fiber mats have numerous bio-engineering and erosion control applications. Coir fiber is a natural, organic fiber made from the outer layer of the fruit of the coconut tree. The fiber is spun into twine which is used to produce these mats. They have high tensile strength and can last from 2-4 years depending on the site. Coir mats are particularly effective on steep slopes that are susceptible to slumping or frost shear. 100% biodegradable leaving no plastic residue behind. Available in three weights: 400 grams/sq.m. (loose weave), 700 grams/sq.m. (medium weave), and 900 grams/sq.m. (tight weave).

Coir (Coconut) Fiber Logs
10′-12′ long, 100% coconut fiber “logs” with biodegradable netting. Coir fiber logs combined with appropriate plant installation have proven to be one of the most efficient and cost-effective methods to stabilize the banks of ponds, streams, rivers, and along the coast. Installation is easily accomplished with either earth anchors or wooden stakes and suitable plant material. Functional longevity 2-4 years depending upon site conditions. Available in 9”, 12″ and 16″ diameters, both regular/standard and dense/premium fill.
These logs work because they fill with soil deposited from up-slope which provides a suitable medium for plant root growth. Roots then fill the coir/soil medium as the coir begins to degrade, and ultimately the roots provide the stability to hold the soil in place and stop erosion. Plant installation is an integral part of the efficacy of coir logs.

Jute Netting (size-4 X 112ft, 448 sq ft, 50 sq yards)
Jute netting is made of 100% organic jute twine, is completely biodegradable and is used for short-term erosion control on slopes of 3:1 or less. Functional longevity is 6-8 months but will vary depending upon soil and climatic conditions.
Constructed of 100% weed-free straw inside a polyethylene net sock. Wattles are 9 inches in diameter x 25 feet long, or 12 inches in diameter x 10 feet long. A cost-effective, sediment-control alternative to hay bales. Wattles should be placed along the contours of recently constructed or disturbed slopes.
Dormant Live Material for Bioengineering
New England Wetland Plants, Inc offers dormant woody Willow (Salix spp.) and Dogwood (Cornus spp.) for use as brush layers, brush fascines, and stakes. Brush layers are 3-5 feet long. Fascines are usually 5-7 feet long and 4-8 inches in diameter. Dormant live stakes are typically 2-3 feet long. Dormant material is only available from mid-November to mid-March.

Tubelings for Bank Stabilization and Soil Bioengineering
- Are easier to install
- Produce soil-stabilizing roots more quickly
- Have a greater chance at survival than dormant live stakes
Tubelings typically measure between 8 inches and 24 inches in height depending upon the time of year. Please be sure to place your order in advance for large quantities. Tubelings are sold in trays of 38.
