Justification of Red List category
A total dependence on one or few species of bamboo whose reproduction is followed by massive die-off events, coupled with a substantial reduction in suitable habitat, suggests that this species's current population is small, fragmented and rapidly declining. It consequently qualifies as Vulnerable.
