Environmentally Sensitive Areas
Any larval food or host plants found within 300 feet of the project footprint will be clearly marked.
a. For projects where Smith’s blue butterfly species are present or assumed to be present, larval food or host plants will be avoided to the maximum extent practicable (see Table 10).
b. For all projects where Smith’s blue butterfly are present or assumed to be present, prior to any ground-disturbing or vegetation removal activities, the edge of the work area near any larval food or host plants will be clearly marked in coordination with a USFWSApproved Biologist to prevent workers and vehicles from entering this area.
c. A Qualified Biologist will supervise the installation of fencing/flagging around stands of known Smith’s blue butterfly host/food plants. The fencing/flagging will be placed the maximum distance from the plants possible (up to 100 feet), while still allowing work to occur in the adjacent area. The location of the fencing/flagging will be field-adjusted by the Qualified Biologist, as necessary. The temporary fencing/flagging will be furnished, constructed, maintained, and later removed on completion of the project. Temporary fencing/flagging will be at least 4 feet high and constructed of high-visibility material (e.g., orange, commercial-quality woven polypropylene or similar material). No heavy equipment will be permitted in the fenced/flagged area. Warning signs indicating the sensitivity of the area will be attached to the fencing/flagging.
d. Not to exceed the self-imposed take limit of no more than 25 host plants lost annually.
