ABSTRACT

The state of Andhra Pradesh is located between latitudes 12°41' and 22°N and longitudes 77° and 84°40'E. The state's geographical area is 1,62,440.1 km², accounting for 5.13% of the country's landmass, and it has 974 km of coastline. The Nandyal Forest Division is in the south-eastern part of the Kurnool district. It is between140 53'58.56" and 150 40'58.08" N and 780 20'27.6" and 780 46'40.08" E in terms of latitude and longitude. The Division covers 2,600 km2, which is 14.73 percent of the total area of the district. Climate the average annual rainfall in this Division is around 914 millimeters, with most of the precipitation coming from the South-west monsoons, and the climate is typically dry, with temperatures ranging from 20⁰ C to 40⁰ C. Black cotton soil, alluvial soil, brown loamy soil, and red soil are the most common soil types Frequency, Abundance, Basal area of woody species, Relative Density, Relative Frequency, Relative Dominance and IVI. Phyto sociological structure of Tree Species The total number of each individual species, namely Trees (26), Shrubs (16), Herbs (23), and Climber (15) species, is found in Phyto sociological Analysis of the Nandyal Forest Division. Frequency of Tree Species 100.00, Density of Tree Species (8.3), Abundance of Tree Species (8.25),  Basal Area of Tree Species (cm²)  (283.53)  Relative Density of Tree Species (10.71) (9.09), Relative Frequency of Tree Species (6.45), Relative Dominance of Tree Species: (8.53),  Importance Value Index (IVI) of Tree species: (22.13) (22.59) and Shrub Species Division contains the total number of each individual species, particularly Shrubs (16) species. Frequency of Shrub Species 100.00, Density of Shrub Species (100m²): (7.5), Abundance of Shrub Species (7.5), Basal Area of Shrub Species (cm²) (122.72), Relative Density of Shrub Species (10.10), Relative Frequency of Shrub Species (6.15), Relative Dominance of Shrub Species: (10.63), Importance Value Index (IVI) of Shrub species: (28.48) . Herb Species- Division contains the total number of each individual species, particularly herbs (23) species. Frequency of Herb Species 100.00, Density of Herb Species (4.0), Abundance of Herb Species: (6.67), Basal Area of Herb Species (cm²) (31.17), Relative Density of Herb Species (12.50 m²) Relative Frequency of Herb Species (7.69),  Relative Dominance of Herb Species (25.20), Importance Value Index (IVI) of Herb species (38.05) and (28.16). Climbers Division: physiology: The total number of each individual species, namely Climber (15) species, are found. Frequency of Climbers: 100.00, Density of Climbers (3.5). Abundance of Climbers (5.0), Basal Area of Climbers: (59.45), Relative Density of Climbers (15.38), Relative Frequency of Climbers: (9.52), Relative Dominance of Climbers, Importance Value Index (IVI) (51.93)(34.12)
