Seed Mix - ERNMX-154 Floodplain Mix or Equivalent 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 ANON -TOXIC, BIODEGRADABLE HERBICIDE TO CONTROL UNDESIRABLE VEGETATION. 2. FOR AREAS THAT ARE STABILIZED WITH EXISTING GRASS COVER, MOW AND AERATE AREA PRIOR TO PLANTING AND/OR OVERSEEDING. 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 9.0 TO 7.0. THE PH ADJUSTMENTS CAN BE MADE USING POWDERED LIME. 4. ALL PLANTING PATTERNS SHALL BE RANDOM AND MIXED TO MIMIC NATURAL LANDSCAPES. • CONTAINER GROWN SEEDLINGS -- AVERAGE OF 8' ON -CENTER 5. VEGETATION SHOULD BE PLANTED AS SOON AS THE AMBIENT SOIL TEMPERATURE IS ABOVE 41' F THROUGH MAY.P 6. 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.. 7. HOLES EXCAVATED FOR THE SEEDLINGS 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/WHIPS 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. FOR DISTURBED AND UN -STABILIZED AREA, THE AREAS COMPACTED BY FOOT OR VEHICLE TRAFFIC SHALL BE AERATED PRIOR TO RESEEDING AREA AFTER TREES AND/OR SHRUBS HAVE BEEN PLANTED. 12. FOR DISTURBED AREAS, BROADCAST THE SUGGESTED SEED MIX BY HAND OR MACHINE EVENLY OVER THE PLANTING AREA AND FOLLOW WITH ALIGHT RAKING OR ROLLING TO ACHIEVE GOOD SEED -TO -SOIL CONTACT. COVER WITH A LIGHT LAYER OF STRAW MULCH. 13. FOR OVERSEEDING AREAS, THE SEED CAN BE BROADCAST BY HAND OR MACHINE DIRECTLY AFTER AERATION OF SOIL. 14. NO STORAGE OF HERBICIDES OR OTHER AGRICULTURAL CHEMICALS SHALL BE PERMITTED NEAR THE PLANT STORAGE OR MITIGATION AREAS. 15. 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. I j' •f ; /MATCHLINE SHEET 4 .

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 IMMORTALITY RATE, CONSIDER AVAILABLE OPTIONS FOR CONTROLLING PEST PROBLEM SUCH AS FENCING TREE SHELTERS AND TREE CAGES TO REPELLENTS INCLUDING IN -SOIL SYSTEMIC TABLETS FOLIAR 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 FOR SEEDLINGS. 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.
