o NC Steep Slope Mix [ERNMX-310] is a steep slope mix for the Piedmont and Coastal Plain regions of NC. This pollinator -
friendly mix provides food and cover for wildlife. This seed mix can be purchased from ERNST Seeds.
o Native Habitat for Strip Mines Mix [ERNMX-1111 is an erosion control and revegetation mix. It's a permanent meadow mix
for wildlife cover and pollinator habitat on disturbed sites. This seed mix can be purchased from ERNST Seeds.
o Native Steep Slope Mix with Grain Rye [ERNMX-181] is a steep slope mix. The native grass and forb species tolerate poor
soils typically found on steep slopes in the eastern United States. Includes ticktrefoils (Desmodium spp.) and partridge peas
(Chamaecrista spp.), both of which are leguminous species. This seed mix can be purchased from ERNST Seeds.

o Native Steep Slope Mix with Grain Rye [ERNMX-181-21 is a steep slope mix. Use this seed mix with grain rye as a cover
crop. Includes ticktrefoils (Desmodium spp.) and partridge peas (Chamaecrista spp.), both of which are leguminous species.
This seed mix can be purchased from ERNST Seeds.
MULCH - TYPE AND RATE OF APPLICATION (pounds/acre) AND METHOD OF ANCHORING:
Application rates of wheat straw shall be 4,000 lbs/acre. On less than 3:1 slopes, tack is not required. On slopes 3:1 or greater, tack
anchoring is required. Rate of application recommended by the NCDEQ NC Erosion and Sediment Control Planning and Design
Manual — Chapter 6.
OTHER VEGETATIVE COVERS — TYPE (S) AND RATE (S) OF APPLICATION INCLUDING
