Abstract

A summary is provided of the natural geographic
distributions of the 29 Tasmanian Eucalyptus
species. The work is based on over 60 000
observations from numerous data sources. A map
on a 10 km x 10 km grid-cell scale is presented for
each species and is accompanied by graphs of the
altitudinal range and flowering times, as well as
descriptive notes on distribution and ecology,
supplemented with a list of key references. The
geographic pattern of species richness is examined
at generic, subgeneric and series levels. Total
species richness is greater in the drier, eastern
regions compared to the wet, western regions of
Tasmania, with highest concentrations of species
occurring mainly in the central east coast and
south-eastern regions. Monocalyptus species
occur in 8% more grid cells than Symphyomyrtus
species but are absent from King Island.
At the series level, greatest species richness is
reached by the Obliquae in the north-east, the
Piperitae in the south-east, the Ovatae on the
central east coast, and the Viminales in highland
areas of the south-east and Central Plateau. Series
Obliquae species are absent from Flinders Island
and are poorly represented in the south-west.
The general patterns of eucalypt distribution and
ecology are reviewed. Species are classified into nine
categories based on the grid cells they occupy within
their geographic range. The most widespread
species are E. delegatensis, E. obliqua, E. ovata,
E. viminalis and the endemic E. amygdalina.
Most species with localised distributions have
been nationally recognised as rare (i.e. E. barberi,
E. morrisbyi, E. perriniana and E. risdonii).
Rare species with regional distributions have either
dispersed (E. cordata) or disjunct (E. archeri)
occurrences. Most species that are rare in
Tasmania are endemics, with the exception of
E. perriniana and E. aff. radiata, although
the taxonomic status of the latter requires
investigation. Unresolved issues relating to the
natural distribution and taxonomic affinities of
the Tasmanian eucalypt species are summarised.
