Claim:
A visually-attenuated erosion control medium formed from hydraulic-application on a ground surface of a slurry comprising a blended mulch product and water, the blended mulch product comprising: ligno-cellulosic fibers; a tackifier; a visual attenuation composition including a colorant selected from the group consisting of a pigment, a dye, and combinations thereof to visually attenuate or camouflage the erosion control medium to approximate color characteristics of natural surrounding terrain; and substantially straight synthetic fibers each having a straight ratio(D not :D max )of at least about 3:5 to about 1:1; wherein D max represents a maximum potential distance of a particular synthetic fiber having a first end point and a second end point, with the first and second end points located at opposing ends of an elongated portion of the particular synthetic fiber, the maximum potential distance being measured along the elongated portion of the particular synthetic fiber when the particular synthetic fiber is completely straight; and wherein D not represents a notional shortest distance between the end points; wherein the erosion control medium forms a substantially homogenous open weave matrix on the ground surface.
