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 Unidentified species Unprotected Area 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)
