The SCC225 has the features of the SC150 as well as coming pre-seeded. A layer of seeds sets on top of biodegradable tissue which is sewn into the bottom of the blanket. The tissue protects and contains the seeds but disintegrates with rainfall. North American Green's C125 is recommended for channel linings, high runoff and extreme slopes. It is made of coconut fiber that is degradable, but it will not disintegrate for several years.

The P300 is made of 100% nylon fibers with heavy netting on one side, and light weight netting on the other. It is a ditch liner and a nondegradable alternative to rip-rap along shorelines.

Arlington, Texas-based American Excelsior Company has also developed a number of blankets that deal with slope and channel erosion problems as well. Its Curlex® I is a wood machined mat of curled wood excelsior with a fiber length of six-inches or longer. The top of each blanket is covered with a photodegradable, extruded plastic mesh. It is best recommended for slopes to 1.5:1 and channels to 5 fps. It is also available with a short 30-60 day life-cycle netting.

The Curlex® QuickGRASS blanket is a dyed green Aspen wood fiber mat made from curled excelsior, with 80% being six-inches or longer in length. It too is for slopes to 1.5:1 and channels to 5 fps and weighs 1.06 lbs./sq. yd. It also has the same 30-60 life cycle netting option as the Curlex® I.

Another blanket that is available from American Excelsior is the Curlex ® II (Double Sided). Is has the same make-up of the Curlex® I and can be used on slopes to 1.5:1 and channels to 7 fps and is good on sandy soils.

The Curlex® III is an excelsior blanket that is constructed of a machined, curled wood fiber, produced in a mat form. Each side is covered with black, heavy-duty, extruded plastic mesh to reinforce the root system after the mat has decomposed. It is recommended for channels to 10 fps and slopes that may need long term protection. It is a heavy mat that weighs 1.62 lbs./sq. yd.

Steep slopes require an erosion control blankets that are both strong and able to biodegrade in time. Coconut fiber adds strength and durability to the blankets ability to withstand heavy runoff while retaining soil particles. Depending on the type of netting used, a blanket can disintegrate in a few weeks or a few years.

Rolanka in Stockridge, Georgia has three types of coir erosion control blankets. The first is the BioD-OCF 30 which is composed of a layer of mattress coir stitched between two organic nets. The blanket has a functional longevity of 24 months. It works well in sandy soil as well as providing support for revegetation in beach and sand dune restoration.

The BioD-SCF blanket is composed like the BioD-OCF 30 but in stitched between polypropylene threads. The nets and threads are photodegradable and deteriorate with time. This is recommended for erosion control in sandy soils with less environmental sensitivity.

Rolanka's BioD-Mat® blankets are woven from machine spun bristle coir twines and are 100 percent biodegradable. They have a field functional longevity of 4-6 years. The blankets are available in three types: BioD-Mat 40, BioD-Mat 70 and BioD Mat 90. The recommended usage on slopes is up to 1:1 for the BioD-Mat 40 and anything greater than 1:1 for the other two.

Nedia of Jamaica, New York features the KoirMat 400, 700 and 900. KoirMat is made from white coir fiber which is extracted from coconut husks which are submerged in fresh water streams for a period of eight to 10 months. During this process known as "retting" the water flowing through the fiber removes many of the impurities. Depending on its application and exposure, Koirmat will last four to eight years. It eventually decomposes and joins the natural ecological cycle, providing soil nutrients in the process.

The right erosion control blanket will establish adequate ground cover and at the same time reduce run off, keeping slopes intact.
