The paper reports the results of the analysis of floral composition and similarity index of six recovering dry tropical forest stands, protected by the local community, for 4-, 6-, 8-, 10-, 12- and 20-year periods in the Koraput region of Odisha, India. A minimum of 67 plant species was recorded in 6-year recovering forest stand, while 4-year stand exhibited 72 plant species. Total number of plant species increased from 6- to 20-year stand exhibiting the highest number of 91 species in 20-year stand. The pooled number of all plant species in all the stands was 173 under 151 genera and 57 families. Totalnumber of herbaceous species declined from 34 in 2-year standto 24 in 20-year stand.Keywords

The paper presents the assessment of the impact of local protection of degraded forest stands for 4, 6, 8, 10, 12 and 20 year periods in the Koraput region of Odisha, India on the structural characters of the herbaceous vegetation. The pooled number of all plant species in all the stands was 173 under 151 genera and 57 families. Total individuals of all herbaceous species recorded were 84, 62, 65, 66, 58, and 53 plants m-2 in 4, 6, 8, 10, 12 and 20 year stands, respectively. Herbaceous stand basal area was 3.4, 1.83, 1.83, 1.86, 1.62, and 1.45 cm2 m-2 in 4, 6, 8, 10, 12 and 20 year stands, respectively. Importance value index (IVI) revealed that Chrysopogon aciculatus, Desmodium triflorum, Vicoa indica, Capillipedium assimile, Jasminum arborescens and Ageratum conyzoidis predominated in 4, 6, 8, 10, 12 and 20 year stands, respectively. Dominance-diversity curve for the six herbaceous stands showed lognormal distribution. Shannon's diversity index (H') and Simpson's dominance index (C) for the six herbaceous stands were almost same in all the six stands. The shift in dominance of herbaceous species with longer protection age suggests the initiation of stabilization process and establishment of shade tolerant species.Keywords
