Orchidaceae
The ANHAT database has 159594 records for 1203 species and subspecies of
Orchidaceae. Three species of Orchidaceae are considered extinct and therefore
excluded from analysis. These species are presented in Table 29.

Four hundred and sixty-eight species of the Orchidaceae are represented by 30 or
fewer record sites in the ANHAT database (Table 31). Of those species, 101 are
categorised as threatened, including 12 species classified as critically endangered and
60 listed as endangered. There are indications that a relatively large number of the
species on this list come from north-east Australia and, to a lesser degree, the south-
west of Western Australia, and there are few inland species on the list. However,
there are species on the list from all over Australia. There are no obvious patterns in
the types of vegetation types with which these species of Orchidaceae are associated,
but the very large numbers of species in the table may be masking some relationships.
These species have been excluded from analysis but are included here for reference.
Exclusion of these poorly recorded species eliminates 6195 records.
