Airport; Human Factors
We landed normally on Runway 13 and cleared at the departure end onto the sole taxiway.  We began a slow taxi northwest toward the ramp  area for parking.  Approximately 1;200 feet north of the departure end; the PIC slowed the aircraft to a stop to evaluate a small reflective marker on a short metal post positioned just left/west of the taxiway.  The PIC maneuvered the aircraft with caution and vigilance so as to avoid the marker.  Once clear the obstacle; the PIC resumed his attention to our forward progress to the ramp; still very mindful of the rising terrain to the left of  the taxiway.  Within moments of clearing the marker; we felt a slight bump along our taxi path and concluded we had passed across an unseen object on the taxiway itself.  We determined it was appropriate to continue our taxi to the ramp for parking.  Upon post-flight inspection; damage was discovered to an approximate four inch area along the leading edge of the outboard left wing.  Brown scuff marks were observed along either side of this indentation. We coordinated with the sole individual on duty at the airport; the facility operations manager; to go out to inspect the area around the reflective marker.  We discovered damage to a dead scrub bush located approximately 20 feet north of the marker that was consistent with the scuffing and small indentation along our left wingtip area.  Of significance is the fact that there is not any notation on the airport diagram of taxiway restrictions; nor any mention of obstructions/ obstacles within the airport property stated in our Flight Release information.  NOTAM/Regulate HBV for taxiway restrictions: aircraft with wingspans greater than XX feet landing Runway 13 will back-taxi on runway and vacate to the ramp from the north end.  Aircraft vacating Runway 13 at the departure end shall have wingspans less than XX feet.  Remove scrub bush and overgrowth along southwest side of taxiway.
G-V First Officer reports damage to the left wing tip during taxi in after landing on Runway 13 at HBV.  Damage was caused by a dead bush along the taxiway.
