Given that most vangas are tied closely to primary forest, and that Malagasy primary forests are under considerable threat, the future of many members of the family is uncertain. The most threatened species are Van Dam's vanga, which is found only in two widely separated populations in highly threatened western deciduous forest, and the lowland rainforest specialists helmet and Bernier's vangas. The latter two species are also only found in the northern half of the rainforest, in which zone lowland forest is fast disappearing due to slash-and-burn cultivation. Bernier's vanga in particular seems to have rather a patchy distribution, being absent from some areas of apparently suitable habitat. The newly described red-shouldered vanga is limited to dense Euphorbia scrub in the south-west of the country, and while this forest occurs on poor soils that are difficult to cultivate, pressure for land from a rising human population has led to recent significant clearance, putting this species under threat in its limited range. There are also some species that have regionally distinct populations that are much more threatened. The Comoros populations of blue vangas are very rare, in particular Cyanolanius madagascarinus bensoni, known from very few sightings and a single specimen from Grande Comore (Ngazidja) and Moheli (Mweli). The western form of the Ty-las vanga, Tylas eduardi albigularis, seems very rare and sparsely distributed, being apparently most common in or near mangroves.
