Indigofera baileyi (a perennial herb) - endangered species listing
The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the perennial herb Indigofera baileyi F. Muell. as an ENDANGERED SPECIES in Part 1 of Schedule 1 of the Act. Listing of endangered species is provided for by Part 2 of the Act.
NSW Scientific Committee - final determination
The Scientific Committee has found that:
1. Indigofera baileyi (family Fabaceae; subfamily Faboideae)is described by P.G. Wilson (in Harden, G., 2002, Flora of New South Wales. Vol. 2 (2nd edition), UNSW Press, Kensington, page 569) as: an erect perennial herb, to 0.4 m high, with woody rootstock; young stems green to brown with fine appressed hairs. Leaves 2.5 - 7.5 cm long; leaflets mostly 7 - 15, elliptic to obovate, 4 - 19 mm long, 2 - 10 mm wide, obtuse with a small mucro; stipules triangular, up to 2 mm long. Inflorescences mostly 11 - 17 cm long, longer than leaves. Calyx sparsely white-hairy, the teeth shorter than the tube. Petals pink to purple. Pods terete, 14 - 29 mm long, glabrous; seeds several, endocarp not, or obscurely spotted. Grows in open woodlands on granite or basalt soils.
2. The species occurs in Queensland and reaches its southern limit in New South Wales. It is restricted to the far north-east corner of the State, north of Wylie Creek.
3. In New South Wales, Indigofera baileyi is known from only four locations across a limited area. None of the known locations are within conservation reserves.
4. Roadside populations are threatened by maintenance works, weed spraying or grazing. Clearing and high frequency fires also threaten existing populations.
In view of the above the Scientific Committee is of the opinion that Indigofera baileyi F. Muell. 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.
