not recorded in the sampling quadrates.

of Chrysopogan fulvus and Setaria sp. were
restricted only to the unploughed area (Table 7) of
the restoration site.
5.3. SPECIES DISTRIBUTION PATTERN
Plant distribution in an area is not homogenous. In
nature, species that produce large number of wind
dispersed seeds get scattered uniformly all over
the area and on germination the plants grow
throughout, while seeds of those species which do
not have such dispersal mechanism, are generally
shed near the plants or they are dispersed by animals
or by other means. Such species are not scattered
uniformly all over the area and their occur-
rence is restricted to aggregation or in patches. The
distribution pattern of species in an area can be
obtained through percentage frequency estimation.
Raunkaier (1934) classified five broad categories of
distribution based on the percentage frequency of
species. This classification was used to evaluate
the distribution pattern of different grass species
present in and around the study sites. Raunkaier’s
frequency classes are as follows:
Class A: Species with frequency from 1-20 per cent
Class B: Species with frequency from 21- 40 per
cent Class C: Species with frequency from 41- 60
per cent Class D: Species with frequency from 61-
80 per cent Class E: Species with frequency from
81-100 per cent.
