The erosion mats and wattles that Western Excelsior manufactures in Mancos are used around the West to stabilize the soil around road projects and new developments.
This summer, they've been used for an less typical purpose: to help restore a riparian area on Taylor Creek, between Dolores and Rico.
The popular but unauthorized camping spot had been badly eroded by vehicle traffic, turning the valley where the Taylor and the Little Taylor converge into a rutted marsh and leaving it susceptible to further erosion.
Because Little Taylor Creek is home to a pure strain of cutthroat trout, the restoration project was a natural for a partnership between the U.S. Forest Service and Dolores River Anglers, which is the local chapter of Trout Unlimited.
The Forest Service provided the expertise for the project, designed by hydrologist Shauna Jensen. A hydrology crew based in Durango brought both experience and muscle, as did District Ranger Derek Padilla.
Dolores River Anglers contributed more muscle and rounded up the materials needed for the project: two truckloads of rock that T&M Dirtworks sold the organization at a good rate; rebar contributed by Saulsbury Enterprises, a firm working on energy exploration in Doe Canyon, and cut and bent by Mike Rosso; grass seed from Southwest Seed, and the mats and wattles donated by Western Excelsior. Not quite three months later, revegetation at the site proves the project was a success.
"People don't realize how fast things will grow once the soil is stabilized," said Fred Christiansen, who is in charge of wattles, Wonderwood and byproduct utilization for Western Excelsior.
KEEPING SOIL IN PLACE
Western Excelsior manufactures a wide variety of rolled erosion control and sediment control products.
Erosion mats are biodegradable netting interwoven with fiber - in the case of the Taylor Creek project, wheat straw that is certified weed-free. The blankets hold the dirt in place while vegetation grows through. Some are colored with vegetable dye for aesthetic reasons.
The mats degrade at various rates, depending on the project. Straw mats with jute netting break down quickly. Long-term mats for use in waterways are made of plastic that will provide years of stability. Western Excelsior also manufactures a mat out of coconut fiber.
"The great thing about aspen is that it's almost like a sponge," Christian said. "It stays wet, holds moisture and lets vegetation grow."
It's also pH neutral, an important attribute in restoration projects.
Staked onto slopes or streambanks, the wattles - bundles of fiber encased in netting - trap sediment while letting water drain through.
On the TU project, they were positioned to prevent erosion until vegetation grew up to stabilize the banks, at which point they will compost into the soil.
Two and a half months after the mats were rolled out and the wattles were staked along Taylor Creek, they are proving their worth. Grass is growing up through the erosion mats, and the streambanks have been stabilized, even though some large animal - perhaps an elk - has done its best to pull some of them apart.
In the Taylor, now protected from motorized traffic and collapsing streambanks, the cutthroats seem at home, wandering at leisure from shadow to sunlight and back. Trout Unlimited and the Forest Service are satisfied as well.
