dissapear. Many of the shrubs
have small runaways that
radiate from the litter or grasses
at their base.
The vegetation was as follows. The
flats were dominated by Ephedra +
low grasses. All of the grass
cover appeared to have been
mowed (only leaves + flower stalks
remained), not one seed head could
be found on a grass plant. All
of the grass had been clipped
at a uniform height. This is due
to the seed harvesting by D. ingens.
Ro The soil was a loosely compacted
clay of fine texture. It would hold
together firmly but once crushed
was a fine powder. Ravines were
dominated by Ephedra, Hymenoxys,
and a Bapplopeppus as well as 2+
compositas. Ballana ravines
had gradually sloped banks +
sandy to pebbly soil. Deeper
ravines (>4 ft) had steep sides
+ rockier, coarser soil. Some
scouring must occur along the
bottoms of steep ravines
