Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2013
Date Assessed: 2011-10-20
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P. & Mill, R.
Podocarpus grayae is very widespread and in many places common, with abundant regeneration. An unquantified decline in the past (mostly more than three generations ago) has now virtually ceased, due to protection of remaining forests and altered forest management. Consequently it is assessed as Least Concern.
Previously published Red List assessments:
1998 Lower Risk/least concern (LR/lc)

Geographic Range [top]

Range Description: Endemic to Australia occurring in northern Queensland and in the Northern Territory (Arnhem Land).

Population [top]

Population: The population can be divided into three subpopulations: the largest on the coast of Queensland between Cooktown and Townsville, a second along the eastern coast of the York Peninsula, and a third in Arnhem Land. The area of occupancy is presumed to be in excess of the threshold for a threatened category and the species is common in many forests.
Current Population Trend: Stable
Additional data:
Continuing decline of mature individuals: No
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Podocarpus grayae is widespread in the subcoastal warm subtropical to tropical rainforests of N Queensland, where it occurs from near sea level to ca. 750 m a.s.l. It can occur on coastal flats directly behind the mangroves, along streams, and on low mountain ridges. In Arnhem Land, Northern Territory, a few small, relict populations occur in patches of rainforest along streams.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: No
Generation Length (years): 40

Use and Trade [top]

Use and Trade: Large trees are a valuable source of timber but data on its exploitation are lacking, primarily due to the fact that it has been described as a new species only relatively recently. It has been erroneouly misidentified as P. neriifolius in the past and its uses may therefore have been similar to those of that widespread (but not Australian) species. It is reported to be in cultivation in some botanic gardens.

Threats [top]

Major Threat(s): Logging and deforestation have reduced the historical area of occupancy of this species, but data are lacking to estimate by how much. This decline has largely ceased and most remaining rainforest is now either in protected areas or managed more sustainably if state owned. What proportion of the population of this species occurs on private land is unknown. In Arnhem Land it is on Aboriginal land and in Kakadu National Park.

Conservation Actions [top]

Conservation Actions: This species is present in several protected areas in much of its range and encompassing all three subpopulations.
