Eucalyptus parramattensis subsp. parramattensis population, Wyong and Lake Macquarie Local Government Areas - endangered population listing

The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the population of Eucalyptus parramattensis C. Hall subsp. parramattensis in Wyong and Lake Macquarie local government areas as an ENDANGERED POPULATION in Part 2 of Schedule 1 of the Act. Listing of endangered populations is provided for by Part 2 of the Act.

NSW Scientific Committee - final determination

The Scientific Committee has found that:

1. Eucalyptus parramattensis subsp.  parramattensis (family Myrtaceae) is a small tree described by K.D. Hill (2002) in  Flora of New South Wales. page 118, Volume 2, Revised Edition, Harden G.J. (ed.). UNSW Press, Sydney.

2. Eucalyptus parramattensis subsp.  parramattensis is not currently listed as an endangered species in Part 1 of Schedule 1 and as a consequence populations of this species are eligible to be listed as endangered populations. (A different subspecies,  E. parramattensis subsp.  decadens is listed as a vulnerable species in Schedule 2 of the Threatened Species Conservation Act).

3. The population of Eucalyptus parramattensis subsp.  parramattensis in Wyong and Lake Macquarie local government areas is at the north eastern limit of the range of the species and is disjunct from other known populations of the subspecies.

4. The current population of the subspecies is estimated to be about 1300 trees in Wyong local government area and about 10 trees in Lake Macquarie local government area.

5. The population is threatened by grazing (which may affect regeneration), localised clearing and effects of septic overflow. Planned road construction and future development may substantially reduce the population and its habitat.

6. In view of the above the Scientific Committee is of the opinion that the population of Eucalyptus parramattensis C. Hall subsp.  parramattensis in Wyong and Lake Macquarie local government areas is facing a high risk of becoming extinct in nature in New South Wales and it is of conservation value at the State or regional level for the following reason: it is disjunct or near the limit of its geographic range.
