5.3.2. Species Distribution Pattern at
Bhirandiyara
The percentage frequency of various plant species
indicated that Cyperus haspan (81.5 per cent) and
Cressa cretica fall under class E and thus showed
a more uniform distribution while Aeluropus
logopoides and Scirpus sp. exercised a random
distribution (class B). The rest of the species fall
under class A and thereby showed aggregation in
nature. Looking at the variation in the distribution

pattern between October and December, species
like Cyperus haspan and Scirpus sp. showed a
reverse trend. The former had shifted from E to D
and the latter from C to A. Thus the distribution of
the latter was very much narrowed during the course
of the post monsoon while Cressa cretica is the
only species which showed a positive trend from
high random (class C) to high uniform (class E)
distribution.
The species such as Cenchrus sp., Eragrostis sp.
and Dichanthium annulatum were totally absent
during the initiation of the study (October).
However, they appeared in the restoration site
during the course of post monsoon while
Sporobolus sp. and Echinocloa sp., showed no
changes in their distribution pattern during the
study period (Table 11). The frequency relationship
showed that, (class A-3, B-0, C-1.D-0 and E-1)
