Commonwealth status: Not listed

Gazetted date: 01 Dec 2017

Description

Erect shrub to 20 cm tall.Branches with a sparse indumentum of simple, bifid and stellatehairs. Leaves have a few simple hairs on midvein and/or margin;petioles 1–1.5 mm long, weakly glandular verrucose; terminal leaflets narrowelliptic to narrow oblanceolate to oblanceolate, 5–8.5 x 1.5–3.5 mm, margins entire to slightly glandular dentate, adaxial surface not glandular verrucose.

Inflorescence usuallyabout equal to subtending leaves, 1–3, sometimes up to 7-flowered, peduncle 3–7mm long, with simple and bifid hairs concentrated between decurrent bractbases; pedicels1.5–3.5 mm long, with a sparse to moderately dense stellateindumentum. Sepals 1–1.5 x 1– 1.3 mm, abaxial surfaces glabrous or with fewstellate hairs towards base. Petals c. 3.5 x 1.7 mm, adaxial surface glabrousor glabrescent, abaxial surface glabrous or with a few hairs near margins.Gynoecium glabrous. Cocci smooth, glabrous. (PlantNet 2016, Duretto MF, Forster 2008).

Distribution

Zieria odorifera subsp. copelandii is endemic to New South Wales. Its distribution is very highly restricted, known only from a single population in Mount Kaputar National Park near Narrabri. The number of mature individuals is estimated to be extremely low with surveys for Zieria odorifera subsp. copelandii in 2012 and 2014 locating 15 individuals over an area of 1 hectare.

Regional distribution and habitat

Threats

Habitat degradation due to grazing by feral goats
Inappropriate fire regimes
The population’s small size and limited distribution make it highly susceptible to weed invasion.
The small population size and limited distribution make it highly susceptible to localised clearing and disturbance.
The only known population is located near a road and road works could have a major negative impact on the population.
With only 15 plants known, ongoing monitoring and threat assessments during a range of environment conditions is required.
Small population size and highly restricted distribution
Impacts to the species, and its habitat, from stochastic events due to highly restricted distribution
Water stress due to prolonger dry periods (e.g. El Niño; drought) Climate change
Known distribution is highly restricted.

Activities to assist this species

Survey potential habitat for additional populations of the species.
Undertake survey to determine entire populations size and demographics
Develop a monitoring plan that aims to determine population health during different environmental conditions and identify known and potential threats.
Ensure this species is considered in NPWS regional pest strategies that aim to control goats.
Ensure land managers are aware of known populations when planning road maintenance and other infrastructure works.
