INSPECTION AND MAINTENANCE:
This consists primarily of two components, stream stabilization
structures (J-Hooks, Cross vanes, etc.) and planting of the stream
banks and riparian areas. In the event that the stream structures
shift, wash away, settle, or otherwise physically cannot function as
designed, contact the area NRCS Agent. If the new plantings
experience a mortality rate of greater than 25%, the dead/dying
plants will need to be replaced.
PERMANENT SEED MIX:
APPLY AT 15 LBS PER ACRE OF DISTURBANCE (per specifications of
seed supplier):
ERNST CONSERVATION SEED MIX ERNMX-178 (FLOODPLAIN MIX)
WHICH INCLUDES THE FOLLOWING SPECIES:
Fox Sedge, Partridge Pea, Dear Tongue, Little Bluestem, Virginia Wild
Rye, Riverbank Wild Rye, Swamp Sunflower, Ox Eye Sunflower, Arrow
Wood, Big Bluestem, Silky Dogwood, Switchgrass, Indiangrass,
Staghorn Sumac, Showy Tick Trefoil, Purple Bergamot, Black Eyed
Susan, Joe Pye Weed , Soft Rush, Giant Ironweed, Tall White Beard
Tongue, Spotted Joe Pye Weed, Bone Set, and Blue False Indigo.

Common Name Scientific Name Rate per Acre Optimal
Planting Dates
Rye grain Secale cereale 30 Ibs Aug 15
- May 15
Browntop millet Urochloa ramosa 10 Ibs May 15

Seedbed Preparation:
Disturbed soils within riparian areas will be amended to provide an
optimum environment for seed germination and seedling growth.
Surface soils will be loose enough for water infiltration and root
penetration. Lime will be added to the soil to ensure a pH level
between 5.5 - 7. Fertilizer (18-46-0) will be added to nutrient deficient
areas. All riparian areas will be raked to loosen compacted soil prior to
seeding.

GREATER THAN 6" (15 CM) MAYBE
NECESSARY TO PROPERLY SECURE
THE BLANKETS.
SLOPE INSTALLATION INSTRUCTIONS:
1. PREPARE SOIL BEFORE INSTALLING BLANKETS, INCLUDING ANY NECESSARY APPLICATION OF LIME,
FERTILIZER, AND SEED. NOTE: WHEN USING CELL-O-SEED DO NOT SEED PREPARED AREA. CELL-O-SEED
MUST BE INSTALLED WITH PAPER SIDE DOWN.
2. BEGIN AT THE TOP OF THE SLOPE BY ANCHORING THE BLANKET IN A 6" (15 CM) DEEP X 6" (15 CM)
WIDE TRENCH WITH APPROXIMATELY 12" (30cm) OF BLANKET EXTENDED BEYOND THE UP -SLOPE
PORTION OF THE TRENCH. ANCHOR THE BLANKET WITH A ROW OF STAPLES/STAKES APPROXIMATELY 12"
(30 CM) APART IN THE BOTTOM OF THE TRENCH. BACKFILL AND COMPACT THE TRENCH AFTER STAPLING.
APPLY SEED TO COMPACTED SOIL AND FOLD REMAINING 12" (30 CM) PORTION OF BLANKET BACK OVER
SEED AND COMPACTED SOIL. SECURE BLANKET OVER COMPACTED SOIL WITH A ROW OF
STAPLES/STAKES SPACED APPROXIMATELY 12" (30 CM) APART ACROSS THE WIDTH OF THE BLANKET.
3. ROLL THE BLANKETS (A.) DOWN OR (B.) HORIZONTALLY ACROSS THE SLOPE. BLANKETS WILL UNROLL
WITH APPROPRIATE SIDE AGAINST THE SOIL SURFACE. ALL BLANKETS MUST BE SECURELY FASTENED TO
SOIL SURFACE BY PLACING STAPLES STAKES IN APPROPRIATE LOCATIONS AS SHOWN IN THE STAPLE
PATTERN GUIDE. WHEN USING THE DOT SYSTEM STAPLES STAKES SHOULD BE PLACED THROUGH
EACH OF THE COLORED DOTS CORRESPONDING TO THE APPROPRIATE STAPLE PATTERN.
4. THE EDGES OF PARALLEL BLANKETS MUST BE STAPLED WITH APPROXIMATELY 2L' - 5" (5 CM - 12.5 CM)
OVERLAP DEPENDING ON BLANKET TYPE. 5. CONSECUTIVE BLANKETS SPLICED DOWN THE SLOPE MUST BE
PLACED END OVER END (SHINGLE STYLE) WITH AN APPROXIMATE 3" (7.5 CM) OVERLAP. STAPLE

INSPECTION AND MAINTENANCE:
This consists primarily of two components, stream stabilization
structures (J-Hooks, Cross vanes, etc.) and planting of the stream
banks and riparian areas. In the event that the stream structures
shift, wash away, settle, or otherwise physically cannot function as
designed, contact the area NRCS Agent. If the new plantings
experience a mortality rate of greater than 25%, the dead/dying
plants will need to be replaced.
PERMANENT SEED MIX:
APPLY AT 15 LBS PER ACRE OF DISTURBANCE (per specifications of
seed supplier):
ERNST CONSERVATION SEED MIX ERNMX-178 (FLOODPLAIN MIX)
WHICH INCLUDES THE FOLLOWING SPECIES:
Fox Sedge, Partridge Pea, Dear Tongue, Little Bluestem, Virginia Wild
Rye, Riverbank Wild Rye, Swamp Sunflower, Ox Eye Sunflower, Arrow
Wood, Big Bluestem, Silky Dogwood, Switchgrass, Indiangrass,
Staghorn Sumac, Showy Tick Trefoil, Purple Bergamot, Black Eyed
Susan, Joe Pye Weed , Soft Rush, Giant Ironweed, Tall White Beard
Tongue, Spotted Joe Pye Weed, Bone Set, and Blue False Indigo.
TEMPORARY SEED MIX AND SPECIFICATIONS:
Common Name Scientific Name Rate per Acre Optimal
Planting Dates
Rye grain Secale cereale 30 Ibs Aug 15
- May 15
Browntop millet Urochloa ramosa 10 Ibs May 15
- Aug 15
Seedbed Preparation:
Disturbed soils within riparian areas will be amended to provide an
optimum environment for seed germination and seedling growth.
Surface soils will be loose enough for water infiltration and root
penetration. Lime will be added to the soil to ensure a pH level
between 5.5 - 7. Fertilizer (18-46-0) will be added to nutrient deficient
areas. All riparian areas will be raked to loosen compacted soil prior to
seeding.
