STREAM -BUFFER MITIGATION GENERAL PLANTING NOTES
1. IF IT IS NECESSARY TO KILL OFF ANY INVASIVE UNDESIRED SPECIES WITH HERBICIDES,
SITE PREPARATION SHOULD BEGIN IN THE FALL PRIOR TO THE TREE PLANTING AND
SEEDING. UNDESIRED SPECIES MAY INCLUDE MULTIFLORA ROSE, HONEYSUCKLE AND
OTHER SPECIES DEEMED TO BE INVASIVE BY THE VIRGINIA DEPARTMENT OF
CONSERVATION AND RECREATION. THE HERBICIDE SHOULD BE APPLIED BY A LICENSED
SPRAY TECHNICIAN USING A NON -TOXIC, BIODEGRADABLE HERBICIDE TO CONTROL
UNDESIRABLE VEGETATION.
2. FOR AREAS THAT ARE STABILIZED WITH EXISTING GRASS COVER, MOW AND AERATE AREA
PRIOR TO PLANTING.
3. FOR AREAS THAT ARE DISTURBED AND NOT STABILIZED WITH EXISTING GRASS COVER,
AREA SHALL BE PREPARED AND ORDERED BY TILLING OR SCARIFYING TO A MINIMUM
DEPTH OF 2". TEST SOIL PH; THE PH LEVEL WITHIN THE GENERALIZED ROOT ZONE OF
STREAM BUFFER MITIGATION PLANTINGS SHOULD BE TESTED AND BROUGHT TO WITHIN A
RANGE OF 6.0 TO 7.0. THE PH ADJUSTMENTS CAN BE MADE USING POWDERED LIME.
4. VEGETATION SHOULD BE PLANTED AS SOON AS THE AMBIENT SOIL TEMPERATURE IS
ABOVE 41 ° F THROUGH MAY.
5. PLANTS SHALL REMAIN UPRIGHT DURING TRANSPORT/STORAGE. PLANTS STORED ONSITE
MUST BE PLANTED WITHIN THREE DAYS OF DELIVERY. IN ADDITION, THE PLANTS SHOULD
BE STORED IN A PROTECTED AREA UPON ARRIVAL IN ORDER TO SHADE THEM FROM
EXPOSURE TO THE SUN AND DRYING WIND. TREES AND/OR SHRUBS THAT CANNOT BE
PLANTED IMMEDIATELY UPON DELIVERY SHALL BE KEPT WELL SHADED, PROTECTED, AND
WATERED. ALL DAMAGED PLANTS SHALL BE REMOVED FROM STORAGE WHEREUPON THEY
MAY BE USED AS MULCH UNLESS THEY ARE DISEASED.
6. ALL PLANTING PATTERNS SHALL BE RANDOM AND MIXED TO MIMIC NATURAL
LANDSCAPES.
7. HOLES EXCAVATED FOR THE TREES SHALL BE 3-TIMES THE CONTAINER DIAMETER OR AT
LEAST 6" WIDER THAN THE BARE ROOT DIAMETER. THE HOLES MAY BE EXCAVATED
EITHER BY HAND SHOVEL OR BY POWER AUGER. EXCESS SOIL GENERATED FROM THE
EXCAVATIONS SHALL BE DISPOSED OF RANDOMLY OVER THE SITE.
8. THE PLANTS SHALL BE SET AT THE SAME DEPTH THAT THEY WERE GROWN IN AND THE
TRUNK SHOULD BE SITUATED NEARLY PLUMB.
9. AVOID PLANTING SEEDLINGS IN EXTREMELY DRY, HOT OR WINDY CONDITIONS. HEAT AND
WIND CAN QUICKLY DRY OUT LEAVES AND ROOTS.
10. WATER THE SOIL AROUND THE SEEDLINGS IMMEDIATELY AFTER PLANTING.
11. AREAS COMPACTED BY FOOT OR VEHICLE TRAFFIC SHALL BE TILLED OR AERATED PRIOR
TO RESEEDING AREA AFTER TREES AND/OR SHRUBS HAVE BEEN PLANTED.
12. BROADCAST THE SUGGESTED SEED MIX BY HAND OR MACHINE EVENLY OVER THE
PLANTING AREA AND FOLLOW WITH A LIGHT RAKING OR ROLLING TO ACHIEVE GOOD
SEED -TO -SOIL CONTACT. COVER WITH A LIGHT LAYER OF STRAW MULCH.
13. NO STORAGE OF HERBICIDES OR OTHER AGRICULTURAL CHEMICALS SHALL BE PERMITTED
NEAR THE PLANT STORAGE OR MITIGATION AREAS.
14. ALL WOODY PLANTS AND SEED MIXES SPECIFIED ARE NATIVE SPECIES. ANY AND ALL
PLANT OR SEEDING SUBSTITUTIONS MUST BE NATIVE. CONTRACTOR TO VERIFY THAT ANY
SUBSTITUTION IS A NATIVE EQUIVALENT AND NOT ON THE VIRGINIA DEPARTMENT OF
CONSERVATION AND RECREATION INVASIVE SPECIES PLANT LIST.
STREAM -BUFFER MITIGATION MAINTENANCE NOTES
WOODY VEGETATION AREAS
1. VISUALLY INSPECT PLANTING AREAS ON AN ANNUAL BASIS.
A. RESEED BARE SPOTS WITH A MIXTURE OF GRASS, PERENNIAL AND/OR WOODY
VEGETATION SEEDS. USE NATIVE SPECIES ONLY.
B. IDENTIFY WEED PROBLEMS WITHIN THE PLANTING AREA.
a. CONTROL WEEDS AS SOON AS POSSIBLE BEFORE THEY GROW OUT OF CONTROL.
WEED CONTROL METHODS WILL VARY, BUT MAY INCLUDE REMOVAL BY HAND,
MOWING, SELECTIVE USE OF HERBICIDES, MULCHING, AND OTHER INTEGRATED
VEGETATION MANAGEMENT (IVM) TECHNIQUES.
b. CONTINUE WEED CONTROL UNTIL WOODY PLANTS ARE FULLY ESTABLISHED IN THE
PLANTING AREA, NORMALLY 2 TO 3 YEARS AFTER PLANTING.
C. INSPECT AREA FOR EVIDENCE OF HIGH DEER BROWSE PRESSURE OR RODENT
POPULATIONS.
a. IF THERE IS EVIDENCE OF HIGH MORTALITY RATE, CONSIDER AVAILABLE OPTIONS
FOR CONTROLLING PEST PROBLEM SUCH AS FENCING, TREE SHELTERS, AND TREE
CAGES TO REPELLENTS, INCLUDING IN -SOIL SYSTEMIC TABLETS, FOLI+AR SPRAYS
OF MANY TYPES AND ACTIVE INGREDIENTS.
D. CHECK SURVIVAL IN LATE FALL AFTER SECOND YEAR TO ESTABLISH SURVIVAL RATE.
MINIMAL SURVIVAL IS 490 PLANTS/ACRE OR A 70% SURVIVAL RATE.
a. IF THE SURVIVAL RATE IS NOT AT THE SPECIFIED MINIMUM AND REPLACEMENT
PLANTINGS ARE WARRANTED, PLANTING AREAS SHOULD BE SURVEYED TO TRY TO
IDENTIFY THE LIKELY CAUSE OF THE PLANT MORTALITY. SOURCES OF THE
MORTALITY SHOULD BE CONTROLLED AND MITIGATED FOR PRIOR PLANTINGS
REPLACEMENTS.
E. CHECK FOR NATURAL REGENERATION. WHERE ABUNDANT, LIMIT FURTHER MOWING
UNLESS SITE IS PRONE TO VOLES OR INVASIVE PLANTS.
F. IF TREE TUBES ARE USED, REGULARLY INSPECT THEM TO MAKE SURE THEY ARE NOT
TOO TIGHT ON THE TREE, THAT SMALL ANIMALS OR INSECTS HAVE NOT BUILT NESTS
INSIDE THE TUBES, AND THAT THE TREE IS GROWING PROPERLY. REPLACE OR
REMOVE THE TUBES AS NEEDED.
G. IN YEARS 3-5, PRUNE AND THIN TREES AND SHRUBS TO ENSURE ADEQUATE
GROWING SPACE AND OPTIMAL GROWTH RATES.
2. VISUALLY INSPECT PLANTING AREAS AFTER MAJOR STORM EVENTS.
A. IF STORM DAMAGE IS PRESENT, FIX EROSION DAMAGE THEN REPLANT AREA AT THE
MINIMUM PLANTING RATE FROM THE ORIGINAL PLANTING PLAN OR RESEED
MANUFACTURES' RECOMMENDED APPLICATION RATE
3. IF POSSIBLE, AVOID WORKING IN THE RIPARIAN AREA BETWEEN APRIL 15 AND AUGUST
15. DURING THIS TIME PERIOD, DISTURBANCE CAN BE DETRIMENTAL TO A VARIETY OF
WILDLIFE, BECAUSE OF MATING AND NEWLY BORN WILDLIFE.
GRASS AND PERENNIAL PLANTING AREAS
1. VISUALLY INSPECT PLANTING AREAS ON AN ANNUAL BASIS.
A. RESEED BARE SPOTS WITH A MIXTURE OF GRASS AND/OR PERENNIAL SEEDS. USE
NATIVE SPECIES ONLY.
B. IDENTIFY WEED PROBLEMS WITHIN THE PLANTING AREA.
a. CONTROL WEEDS AS SOON AS POSSIBLE BEFORE THEY GROW OUT OF CONTROL.
WEED CONTROL METHODS WILL VARY, BUT MAY INCLUDE REMOVAL BY HAND,
MOWING, SELECTIVE USE OF HERBICIDES, MULCHING, AND OTHER INTEGRATED
VEGETATION MANAGEMENT (IVM) TECHNIQUES.
2. MOW ON AN ANNUAL BASIS TO CONTROL WOODY VEGETATION GROWTH.
3. VISUALLY INSPECT PLANTING AREAS AFTER MAJOR STORM EVENTS.
A. IF STORM DAMAGE IS PRESENT, FIX EROSION DAMAGE THEN REPLANT AREA AT THE
MINIMUM PLANTING RATE FROM THE ORIGINAL PLANTING PLAN OR RESEED
MANUFACTURES' RECOMMENDED APPLICATION RATE
4. IF POSSIBLE, AVOID WORKING IN THE RIPARIAN AREA BETWEEN APRIL 15 AND AUGUST
15. DURING THIS TIME PERIOD, DISTURBANCE CAN BE DETRIMENTAL TO A VARIETY OF
WILDLIFE, BECAUSE OF MATING AND NEWLY BORN WILDLIFE.
