Ecorestoration of Banni Grassland Species October (n = 40) 34 Table 11: Frequency and Relative Frequency of Species in Bhirandiyara % Frequency / Distribution Class December (n = 40) % Frequency/ Overall Average Distribution class N=200 % Frequency / Distribution Class C. haspan 36 90.0 / E 27 67.5 / D 163 81.5/E Sporobolus sp. 4 10.0 /A 6 15.0/A 34 17.0/A Cressa sp. 24 60.0 / C 39 97.5 / E 164 82.0 / E Aeluropus sp. 6 15.0/A 12 30.0 / B 62 31.0/B Eragrostis sp. 0 0.0 1 2.5 /A 1 0.5/A Echinocloa sp. 4 10.0/A 6 15.0/A 27 13.5/A Cenchrus sp. 0 0.0 1 2.5/A 3 1.5/A Dichanthium sp. 0 0.0 0 0.0 3 1.5/A Scirpus sp. 18 45.0 / C 8 20.0 / A 55 22.5 / B Species in all the three categories of slopes and unploughed area, while it showed aggregation in other areas. Sporobolus sp. aggregations were found in all the amendments and outside except in vertical slopes where it showed class B while Cenchrus sp. showed aggregation in all the slopes (Table 12). The frequency relationship established for unploughed area was (class A-2, B-2, C-0, D-0 and E-2) A=B>C=DB>C=DB>CE in narrow vertical slopes and (class A-3, B-1, C-1, D-2 and E- 0) A>B=CE in narrow horizontal slopes. The former three amendments highlight higher values of E than D while the latter two amendments showed a reverse trend, lower E value than D. The unprotected area showed (class A-2, B-0, C-0, D-0 and E- 2) A>B=C=D
S. No Species 5.4 SPECIES DOMINANCE The species, which exert major controlling influence on the community by virtue of their size, numbers, production are called dominant. Simpson (1949) has devised a formula for estimating the Index of Dominance (C = E (ni / N) 2 ) based on the biomass value of species, that highlights the importance of each species in relation to the community as a whole. 5.4.1 Species Dominance at Dhordo Table 13: Dominance Index of Plant Species at Dhordo Restoration Site Unploughed Ploughed Area 1 Cyperus rotundus 0.004 0.01 0.08 0.05 Sporobolus sp. forms the dominant species in both ploughed and unploughed areas of the Dhordo restoration site while at site B and C, Cyperus rotundus was the dominant. The dominance index of seven species; Cyperus rotundus, Chloris barbata, Aeluropus logopoides, Gandhiro, Echinocloa sp., Cenchrus sp. and Tetrapogan tenellus was comparatively higher in the ploughed Ecorestoration of Banni Grassland Unprotected Area Prosopis juliflora 2 Chloris barbata 0.006 0.04 0.03 0.04 3 Sporobolus sp. 0.114 0.07 0.02 0.001 4 Setaria sp. 0.006 0.003 0.004 0.02 5 Aeluropus logopoides 0.001 0.002 0.05 0.02 6 Eragrostis sp. 0.008 0.002 0.003 0.02 7 Gandhiro* 0.001 0.0007 0.0004 0.01 8 Echinocloa sp. 0.002 0.0009 0.0003 0 9 Cenchrus sp. 0.009 0.02 0 0.00002 10 Dactyloctenium aegyptium 0.0002 0.0001 0 0.000985 11 Tetrapogan tenellus 0.0002 0.0003 0 0.00013 12 Dichanthium annulatum 0.013 0.005 0.002 0.00001 Unidentified area than the unploughed area. At site B, Aeluropus logopoides forms the second dominant and was followed by Chloris barbata and Sporobolus sp. At site C, the second dominant species was Chloris barbata while Sporobolus sp. and Cenchrus sp. forms the less and least dominant’ species respectively (Table 13). 5.4.2 Species Dominance at Bhirandiyara Table 14: Dominance Index of Plant Species at Bhirandiyara S. No Species Unploughed Ploughed Slope Broad In Bhirandiyara, Cyperus haspan forms the dominant species in all the amendments and unprotected area except in narrow vertical slopes where Aeluropus logopoides exerted domination. Sporobolus sp. was found to be second dominant in ploughed and broad slopes whereas it was third dominant in narrow vertical and horizontal slopes (Table 14). Cenchrus sp. was least dominant in unploughed and narrow horizontal slopes but, totally absent in ploughed and unprotected area.
