Fig. 1 . View from the crest of a strike ridge over the savannah country just east of, but similar to, 
that in which the transects were laid out. The foothill in the foreground rises fairly abruptly from the foot 
slopes, which end against a forested narrow flood-plain. In the farther distance is another strike ridge 
shadowed by clouds and backed by Bootless Inlet. 
belt of 50 m width parallel with the creek at 
transect 1, but extending over 300 m from the 
gully at transect 2. The soil of the flood-plain 
is an organic black clay. 
THE VEGETATION 
The Themeda australis-Eucalyptus savannah 
has a tree stratum of one or more of the 
Eucalyptus species E. alha, E. conferti flora , and 
E. papuana , and some scattered Alhizia procera; 
and a grass cover dominated by Themeda 
australis, with Heteropogon contortus and 
Sehima nervosum commonly associated, the 
latter especially on stonier soils. A shrub layer 
is only locally developed; Albizia procera and 
Cycas media are the more important species. 
This type of savannah occurs on both transects, 
except for a fringe of forest and tall grass on 
the narrow flood-plain.
