Forests Types in New South Wales: Research Note 17 (Forestry Commission of NSW 1989)<br />

The New South Wales forest types study was based on a floristic classification of over-storey<br />

species and describes a total of 184 native vegetation types as well as six non-native and three<br />

non-vegetated units. The study has limitations for use in the present study as it was developed<br />

primarily for timber production and focuses mainly on forest communities and less on shrublands<br />

and non-woody communities. However, the forest types scheme has been widely used and forms<br />

the basis for many of the communities identified through the New South Wales Comprehensive<br />

Regional Assessment (see below). That scheme has been used in the current study to assist in the<br />

interpretation of woody communities and the relationships between them.<br />

New South Wales Comprehensive Regional assessment: Forest ecosystem<br />

classification and mapping for Upper and Lower North east CRa regions (NPWS CRa<br />

Unit 1999a)<br />

A classification of forest ecosystems was carried out by the NPWS CRA Unit in 1999 as a part<br />

of the Comprehensive Regional Assessment study. The study identified a total of 157 forest<br />

ecosystems, 141 of which were eucalypt dominated. Many of these eucalypt-dominated<br />

communities were identified by splitting or amalgamating forest types; 43 forest types were<br />

included without modification (NPWS 1999a). As the methodology of the study relied heavily<br />

on the data and classification of forest types, the forest ecosystem classification has limited<br />

application for non-commercial forest types and non-woody ecosystems in general. However,<br />

as with forest types, many subsequent, finer scale studies have used the forest ecosystems<br />

classification as a basis for further division of vegetation communities; therefore, the current<br />

study had to take forest ecosystems classification into account when analysing relationships<br />

with communities identified through other studies.<br />

a Compliation Map of Native Vegetation for New South Wales (Keith 2002)<br />

The compilation map of native vegetation is developing a consistent vegetation classification<br />

for New South Wales based on a compilation of numerous regional studies and is periodically<br />

updated. It lists 16 vegetation formations, which are further divided into 99 classes. The work<br />

is described in detail in Ocean shores to desert dunes: the native vegetation of New South Wales and<br />

the ACT (Keith 2004). The vegetation classification is currently the most widely used state-wide<br />

and, therefore, has been used as a broad-scale basis for the current vegetation classification<br />

and mapping project. Where possible communities described in the current study have been<br />

equated to formations and classes described in the compilation map, however, in some cases<br />

this has not been possible and some suggested equivalencies are more precise than others.<br />

New South Wales Vegetation Classification and assessment (Benson 2006)<br />

New South Wales Vegetation Classification and Assessment (NSWVCA) is an ongoing project,<br />

being carried out by staff at the Botanic Gardens Trust, which aims to develop a comprehensive<br />

classification of native vegetation across the state as well as an assessment of the conservation<br />

significance of vegetation communities. The project also aims to compile this state-wide<br />

classification into a database to allow the information to be conveniently accessed and analysed<br />

(Benson 2000). Work on this large project has been divided into four parts:<br />

part 1 (largely completed): covers the New South Wales Western Plains<br />

part 2 (currently in early stages of development): to cover the New South Wales Western<br />
