The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list Diuris sp. aff.chrysantha (Byron Bay) (D.L. Jones ORG 2761), an orchid, as an ENDANGERED SPECIES on Part 1 of Schedule 1 of the Threatened Species Conservation Act. Listing is provided for by Part 2 of the Act. Diuris sp. aff.chrysantha (Byron Bay) (D.L. Jones ORG 2761) was provisionally listed as an endangered species on Part 1 of Schedule 1 of the Act.

NSW Scientific Committee - final determination

The Scientific Committee has found that:

1. Diuris sp. aff.  chrysantha (Byron Bay) (D.L. Jones ORG 2761), a donkey orchid, is a distinct taxon, distinguishable from  Diuris chrysantha on the basis of labellum shape and smaller flowers. It is possible that early records of Diuris abbreviata from the Byron Bay area are Diuris sp. aff. chrysantha.

2. The species is currently known in New South Wales from a single population of less than 100 plants.

3. The species has been reduced in extent of geographical distribution by loss or modification of habitat. The single known population is threatened by loss of habitat from residential subdivision.

4. In view of 2 and 3 above the Scientific Committee is of the opinion that the species is likely to become extinct in nature in New South Wales unless the circumstances and factors threatening its survival or evolutionary development cease to operate.
