Threats

Major Threats
On Mount Kilimanjaro and the Ngorongoro crater, this species is threatened by habitat loss resulting from small-holder farming and possibly disturbance from tourism. It is also probable that it is threatened by agricultural expansion in other parts of its range. It is suspected that global warming may become a threat in the near future to the mountain habitats of this species. The glacier on Kilimanjaro has significantly already significantly retreated.

Management

Conservation Actions

Conservation Actions
This species occurs in protected areas on Kilimanjaro and Meru. There are current plans to survey the Kenyan populations in near future (Nick Oguge pers. comm.). Further studies are needed into the distribution, abundance, breeding biology and general ecology of this species. Further information is also required on the status of its habitat to monitor the potential impacts of climate change.
