National Forest Inventory Continental Database; BRR, Australia

National Forest Inventory Continental Database is a database of forest
resource attributes covering all land tenures for Australia and
Territories. Forest is defined as woody vegetation in excess of 5
metres in height, with a projective foliage cover of >30%. The NFI is
also collecting information outside this definition. The data is
collected by aerial photo interpretation, field measurements, field
Specimens, field notes, maps, and remote sensing data from
satellite. The database is made up of separate State wide databases
that have been normalised and collated into a single database. Scales
and levels of completeness vary between state and within states.
These gaps are being addressed by NFI funded regional and local scale
projects.

The data base includes gf (Growth form of the vegetation), g1/s1 (the
most abundant or physically predominant species in the tallest
stratum), g2/s2 (another species that is always present and
conspicuous in the tallest stratum), g3/s3 (species selected from any
stratum, usually a lower stratum as an indicator species or to
destinguish between associations), minh (minimum height in metres),
maxh (maximum height in metres), medh (median height derived through
consultation with the suppliers of the data), h_class (height class as
per Walker and Hopkins (1990)), minpfc (minimum projective foliage
cover), maxpfc (maximum projective foliage cover), medpfc (median
projective foliage cover), mincc (minimum crown cover), maxcc (maximum
crown cover), minc (minimum crown separation ratio), maxc (maximum
crown separation ratio), c_class (cover classes as per Walker and
Hopkins (1990)), plant_code (equivalent to frq_code for plantations),
and description (description of the type of plantation). The data is
available in ArcInfo EXPORT format (the interchange format for this
Geographic Information System). The data set is about 500 megabytes.
