A five year project (2005-10) funded by DBT (Govt. of India) enumerated, identified and analyzed forest vegetation, its diversity, distribution and composition across 444 sample plots spread over 222 hacters in the district of Angul, Boudh, Bolangir, Cuttack, Ganjam, Kalahandi, Kandhamal, Khurda, Nayagarh and Rayagada districts. The simple plots were laid in dry deciduous, moist deciduous and semi evergreen forest zones occurring in the Eastern Ghat region of India (between 19062′ N – 21074′ N Lat.). In total 78,356 trees was measured along with collection of data of 257 tree species. There has been no earlier record of floristic diversity and population studies at landscape level in Odisha until the present one.
In total of 884 plant species (263 species of trees, 78 species of shrubs, 138 species of climbers/ twinners and 405 herb species) were recorded from the Eastern Ghat region. They belong to 532 genera under 129 plant families and constitute 32.6% of plant species recorded over the whole of Odisha, which is estimated as 2,700 species (Saxena&Brahmam, 1994).
Out of 256 tree species enumerated from the study area in Eastern Ghat of Odisha, the 10 major species are Shorearobusta (IVI=17.36), Lanneacoromandelica (IVI=6.76), Madhucaindica (IVI=6.72), Diospyrosmelanoxylon (IVI=6.68), Terminaliaalata (IVI=6.02), Anogeissuslatifolia (IVI=5.96), Buchananialanzan (IVI=5.86), Schleicheraoleosa (IVI=5.85), Brideliaretusa (IVI=5.76) and Syzygiumcumini (IVI=5.71) in term of frequency of occurrence, density and dominance (IVI= Importance Value Index).
- Quantitative assessment of the geographic distribution and population’s status of the plant resources of the Odisha portion of Eastern Ghats.
- Identifying the threats on the plant resources and enlisting the threatened species.
- Analyzing the spatial and temporal patterns of change in specific plant resources along the Eastern Ghats.
