Scientific Name: Macrozamia macdonnellii (F.Muell. ex Miq.) A.DC.

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2009-10-31
Assessor(s): Hill, K.D.
Reviewer(s): Donaldson, J.S. & Bösenberg, J.D.
Justification:
Not regarded as threatened at present due to large numbers and relatively little threat from land use. This species is listed as Least Concern, however, monitoring is required to see if the decline in the Black-footed Rock Wallaby has a significant negative impact.

Population [top]

Population:A locally abundant and stable species.
Current Population Trend:Stable
Additional data:
Number of mature individuals:10000-20000
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found widely scattered on thin soils on rocky slopes, in Triodia grassland or open woodland. They usually occur in shaded gullies or sheltered gorges and also grow on hills of both metamorphic and sedimentary rock.
Systems:Terrestrial
Generation Length (years):60

Threats [top]

Major Threat(s): There is concern about an apparent decline in the Black-Footed Rock-wallaby, Petrogale lateralis, populations (see http://www.iucnredlist.org/apps/redlist/details/16751/0). If Rock-wallabies undergo a decline this may have an adverse effect on seed dispersal. Plants are also poached by collectors.

Conservation Actions [top]

Conservation Actions: This species is listed on Appendix II of the CITES Appendices. Plants occur in the Alice Springs Telegraph Station Historic Reserve, Arltunga Historic Reserve, Finke Gorge National Park, Ruby Gap Nature Park, Watarrka National Park and the West MacDonnell National Park.
