Maundia triglochinoides (a herb) - vulnerable species listing

NSW Scientific Committee - final determination



The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list Maundia triglochinoides F. Muell., a herb as a VULNERABLE SPECIES on Schedule 2 of the Threatened Species Conservation Act. The listing of Vulnerable Species is provided for by Part 2 of the Act.

The Scientific Committee has found that:

1. Maundia triglochinoides F. Muell. (Juncaginaceae), is an erect rhizomatous perennial herb. It is described by Jacobs 1993 (in Harden, G.(ed). Flora of New South Wales. Vol. 4. page 19. UNSW Press, Sydney) as: Perennial with rhizomes c.5mm thick and emergent tufts of leaves arising along their length. Leaves triangular in cross section, to 80cm long, 5-10mm wide. Inflorescence to 10cm long and 2.5cm wide. Carpels 6-8mm long, sessile, each with a spreading beak. Flowers during warmer months. Grows in swamps or shallow fresh water on heavy clay.

2. Maundia triglochinoides is a monotypic genus. Maundia triglochinoides is almost restricted in its distribution to coastal New South Wales, extending into southern Queensland.

3. There are historic records of Maundia triglochinoides in the Sydney region, but the current southern limit is near Wyong. Former sites in Sydney are either no longer wetlands or have been greatly disturbed.

4. Maundia triglochinoides occurs in permanent swamps and wetlands on the central and north coasts of New South Wales; although locally common at individual sites the number of known locations is small and these are highly scattered. The habitats in which it grows are vulnerable to filling, changes in hydrology, water quality and weed invasion.

5. In view of the historic contraction in range, and the vulnerability of the remaining habitat to change the Scientific Committee is of the opinion that Maundia triglochinoides is likely to become endangered unless the circumstances and factors threatening its survival or evolutionary development cease to operate and therefore is eligible to be listed as a Vulnerable Species.
