Conservation and threats

Four subpopulations have been recorded. The overall population and population trends are not well understood. The population in Andohahela National Park is thought to be well protected. Those outside the park are subject to habitat loss and degradation, including deforestation for timber and fuel wood, and human-set fires to clear land for livestock grazing, shifting agriculture. The species is assessed as
