As of the 2025-2 update, six Lambertia species are on the IUCN Red List of Threatened Species, with five of them being threatened with extinction. Two species (L. ilicifolia and L. inermis) are listed as vulnerable, two more (L. echinata and L. multiflora) are listed as endangered and one, L. fairallii is listed as critically endangered.[3] The Environment Protection and Biodiversity Conservation Act 1999 also lists L. echinata subspecies citrina and occidentalis and L. orbifolia as endangered and L. fairallii as critically endangered.[4]
Habitat destruction, increased bushfire frequencies and the pathogen which causes dieback disease, Phytophthora cinnamomi are the greatest threats to these species.[3]
