Thymelaeaceae

The ANHAT database has 45371 records for 112 species and subspecies of 

Thymelaeaceae.  One species of Thymelaeaceae is considered extinct and therefore 

excluded from analysis. This species is presented in Table 161.

Six species account for approximately 50% of the total species records in ANHAT 



(Table 162). These species have over 1500 records each.  Pimelea glauca has over 

7000 records.

Fourteen species had 30 or fewer individual site records in the ANHAT database 

(Table 163). This is a relatively low percentage of species with few records.  Three of 

these species are classified as threatened (including one species classified as 

endangered). There are few species on this list and none of the species appear to be 

located in northern Australia.  The range areas are all smaller than 2000 km

.  



Exclusion of these poorly recorded species eliminates 229 records.

Removal of extinct and poorly recorded species leaves 45137 records in ANHAT for 

97 species (and subspecies). The mean number of records per species for species with 

greater than 30 records was 465, with a mean % of records in NRS.

Twenty-one species of Thymelaeaceae had 45% or greater of individual site records 

located within PAs (



Table 164). This is just under one-quarter of the species with more than 30 records.  

One species is classified as vulnerable. These species are scattered across Australia 

and have varying sizes of ranges.  There are no species listed as occurring in inland 

Australia.  Four species have over 90% of their available record sites falling within 

PAs.

Eleven species had less than 10% of ANHAT records located within PAs (Table



165), which is a relatively lower proportion of species. Four are classified as 

threatened, including one critically endangered and one endangered species. Three 

species have no records within PAs.  There is not much data to indicate patterns in 

these species.  Perhaps species in this category tend to come from eastern Australia.

over one-quarter of the species with more than 30 records. Four species were listed as 

threatened, including one species classified as endangered. Again, three species are 

not known from any PAs in the NRS.  The majority of species in this list had fewer

Anthericaceae

The ANHAT database has 36803 records for 105 species and subspecies of 

Anthericaceae. No species of Anthericaceae are considered extinct.

Six species account for approximately 50% of the total species records in ANHAT 

(Table 169). These species have over 1000 records each.  Arthropodium strictum is 

represented by over 5400 records.

Twenty-six species, about 25%, had 30 or fewer individual site records in the 

ANHAT database (Table 170). Three species are classified as threatened (including 

one species classified as endangered).  The majority of these species come from 

Western Australia and all ranges are under 2000 km

. Information on vegetation 



associations is not available for this report. Exclusion of these poorly recorded species 

eliminates 360 records.

Removal of extinct and poorly recorded species leaves 36443 records in ANHAT for 

79 species (and subspecies). The mean number of records per species for species with 

greater than 30 records was 461 (mean 32% records in the NRS).

Twelve species of Anthericaceae had 45% or greater of individual record sites located 

within PAs (Table 171). None are classified as threatened. The highest level of 

reservation was just under 80%.  The locations of these few species are distributed 

across Australia and show no pattern.  The size of the ranges varies greatly.
