1. A vegetation growth-enhancing erosion control blanket having a first surface and a second surface opposite thereto, said blanket consisting of:
a single layer, net-free flexible mat constructed of a multiplicity of elongated excelsior fibers disposed in a randomly intertwined relationship, the outer exposed areas of said multiplicity of fibers defining said first and second surfaces of said blanket;
said multiplicity of elongated excelsior fibers collectively defining in said net-free mat a multiplicity of interstitial regions and defining said blanket through which portions of growing vegetation may pass generally transversely, at least a major portion of said elongated excelsior fibers being held in place with a thread stitched therefrom in a manner providing said net-free mat with structural integrity;
said first and second surface of said net-free flexible mat being net-free and consisting solely of said multiplicity of elongated excelsior fibers and said thread; and
and said first and second surfaces forming the top and bottom, respectively, of said net-free mat.
