Justification
A population reduction of at least 50% is estimated based on a 74% reduction in range and loss of 55% of this species' habitat in the past 60 years (generation length 20 years). It is currently threatened by urban expansion, afforestation, inappropriate fire management, alien plant invasion, habitat fragmentation an susceptibility to root fungal infections. Habitat loss models indicate that the population may decline by >80% by 2025 (Bomhard et al. 2005). However, given that this charismatic species is intensively managed, such drastic declines are unlikely.
