Excelsior erosion mat is an invaluable tool for reseeding an area with any type of slope.  Excelsior erosion mat will help hold soil, will hold seed in place, and will provide protection for seed and seedlings from birds and the hot sun.  Excelsior mat is made from shredded aspen trees so it is organic and is biodegradable.  Just roll the matting out over a prepared seed bed and leave it in place.  Once the seed has germinated, the excelsior mat will hold the soil in place for several months then decompose and become mulch.
