In this classification it is presumed that the class E
and D reflects high to moderate uniform distribution,
class C and B showed high to moderate random
distribution while class A reflects aggregation
of species.
5.3.1. Species Distribution Pattern at Dhordo
At Dhordo restoration site, of the 12 important
selected species (Table 8), Cyperus rotundas and
Cressa cretica fall under class D and surprisingly
no species were recorded under Class E. The species
such as Chloris barbata, Sporobolus sp. and
Eragrostis sp. fall under class B while a maximum
of 8 species (67 per cent); Setaria sp., Aeluropus
logopoides; Gandhiro, Echinocloa sp., Cenchrus
sp., Dactyloctenium aegyptium, Tetrapogan
tenellus and Dichanthium annulatum were
registered under class A.
Table 8 also highlights that, there was a slight
variation in the distribution of certain species
during the period between September (beginning
of study) and November (end of study). During the
course of the post monsoon, the distribution of
species such as Chloris barbata shifted from class
A to B, Sporobolus sp. from A to C, Cressa cretica
from C to D, Aeluropus logopoides from A to B
and Cenchrus sp. from A to B while only one

species, Cyperus rotundas showed a reverse trend
from D to C (Table 8). However, among all,
Sporobolus sp. showed a maximum increase in its
distribution range during the study period while
there was not much variation in the distribution of
other species. The relationship between different
frequency classes (class A- 9, B-1, C-1, D-1 and E-
0) enunciated during September are A>B=C=D>E
and, in November the trend was (class A-6, B-4, C-
2, D-1 and E-0) A>B>C>D>E. Thus, at the beginning
and at the end of the study period, the value of E
was lower than D in the Dhordo restoration site.
From the Table 9 it is clear that, certain species
have distributional variation under different soil
amendments in Dhordo. The species such as
Cyperus rotundus, Chloris barbata, Cressa erotica
and Cenchrus sp. showed more distribution in the
ploughed area than in unploughed area. Eragrostis
sp. is the only species which had healthier distribution
in unploughed area while species like
Sporobolus sp., Setaria sp., Aeluropus logopoides,
Gandhiro, Echinocloa sp., Dichanthium
annulatum, Dactyloctenium aegyptium and
Tetrapogan tenellus registered no changes in their
distribution class under ploughed and unploughed
conditions. The frequency relationship established
shows that, (class A-9, B-2, C-1, D-1 and E-0)
