This species is threatened by habitat loss due to fire (uncontrolled fire, fire for grazing, fire for slash and burn), artisanal mining (Itremo Massif) and grazing. It is also threatened by drought as the habitat of this species in wetland.

Habitats préférentiels (classification IUCN)

  • 1_9Forest - Subtropical/Tropical Moist Montane
  • 2_1Savanna - Dry
  • 3_5Shrubland - Subtropical/Tropical Dry
  • 5_3Wetlands (inland) - Shrub Dominated Wetlands
