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