4.1 AVAILABLE INFORMATION
4.1.1 Sources of data
Plant species records from the DRP have been extracted from the databases of the Royal
Botanic Gardens (NSW), National Herbarium, NPWS Wildlife Atlas and other vegetation
surveys within the DRP. Other herbaria may also have plant records from the DRP but this
information will be obtained as part of the DRP vegetation mapping, biodiversity survey and
conservation assessment projects.
Threatened species under the TSC Act, Schedule 13 species listed under the National Parks
and Wildlife Act, 1974 (NSW), and ROTAP (Rare and Threatened Australian Plants) species
were taken from the complete list. The provenance, distribution of the remaining plant species
and most recent common names were determined from Harden (1990-94) and exotic species
were then removed from this list and placed in a separate database. Records of questionable
accuracy or those species not described by Harden were further investigated using the Royal
Botanic Gardens Plants of NSW Database. Distribution and current common names were
checked. Species still considered or a questionable reliability were deleted from the list.
Separate lists of historical records (pre-1970) and extinct flora were also created.
Systematic surveys
Only a limited number of systematic floristic surveys have been conducted in the DRP and
these are listed in Table 4.1 Not all of these surveys have full floristic sampling or precise
location information (such as AMG reference) and some of the studies included sites from
outside the DRP.
