Threats [top]

Major Threat(s): The main threats are the disturbance of sensitive areas, fires and landslides. Several unfavourable intrinsic factors such as a low regeneration rate further reduce the survival chances of this species (Fernandes et al. in: Martín et al. 2008).

Conservation Actions [top]

Conservation Actions: Pittosporum coriaceum is listed as priority species on Annex II of the Habitats Directive and under Appendix I of the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention).
The entire range is contained within the National Park of Madeira. Efforts are being made to propagate the species, with limited success. Species recovery and reintroduction programmes should continue, together with campaigns to raise public awareness. Biology and ecology, population dynamics, threats and impacts of conservation actions should be studied further (Fernandes et al. in: Martín et al. 2008).
