Claim:
An erosion control netting assembly comprising: a first extruded plastic net; a second extruded plastic net secured to the first net; and a fiber matrix disposed between the nets, wherein each of the first and second nets comprises: a plurality of generally first direction members spaced apart from each other and a plurality of generally second direction members spaced apart from each other and attached to the generally first direction members to form joints at the intersections of the generally first direction members and the generally second direction members, the first direction members having a first strand count/inch (FDSC) and the second direction members having a second strand count/inch (SDSC), greater than or substantially equal to the first strand count/inch, with adjacent generally first direction members and intersecting adjacent generally second direction members cooperating to form openings in the first net that are engineered, or sufficiently sized, to enable small animals to traverse or weave through the erosion control netting assembly without getting trapped in the openings, the (FDSC)/(SDSC) being no more than 0.4.
