not transplanted at the beginning of construction operations. Prior to
construction operations, Contractor shall tag plants to be transplanted
with plastic or vinyl tape tied to the plant caliper. Plants to be
transplanted shall be protected from root compaction and any other damage
(with barrier of metal poles a maximum of 2.5 meters8 feet on center with
plastic fluorescent netting) at a minimum of 6 meter20 foot diameter from
outside of the plant's trunk prior to the start of any construction
operations. Where tree drip lines are greater than 3 meter10 feet from the
tree's trunk, locate barrier fencing at the drip line of the tree. Plastic
tape and barrier fencing shall not be removed until transplanting
operations are ready to begin and or instructed by the Contracting Officer.
Contractor shall water and prune plant material as necessary to keep
healthy and vigorous, particularly when water is shut off. Contractor

in working order. Outside storage locations shall be continually shaded
and protected from the wind. Bare root plants shall be heeled in. Plants
stored on the project shall be protected from any drying at all times
covering the balls or roots with moist sawdust, wood chips, shredded bark,
peat moss, or other similar mulching material.
