Floristic status of tropical deciduous forests in Odisha, Eastern India
Floristic analyses of tropical deciduous forests were carried out in four randomly selected forest ranges (Palhara sub-division of Angul, Gandhamardan hills of Bargarh, Telkoi forests range of Keonjhar, and Similipal Biosphere Reserve of Mayurbhanj districts) of Odisha, Eastern India by laying 32 belt transects each of 0.10 ha size. A total of 65 plant species belonging to 56 genera and 32 families were recorded in the present study, of which Euphorbiaceae was the most dominant family with eight species (12.31%). Species diversity (Shannon–Wiener's Index) and concentration of dominance (Simpson’s Index) were 3.08 and 0.09 for trees, 2.72 and 0.12 for shrubs, and 2.83 and 0.08 for herbs, respectively. On the other hand, Margalef’s index of species richness (Dmg) was 8.08 for trees, 4.48 for shrubs, and 4.69 for herbs while, Menhinick’s index of species richness (Dmn) was 1.17 for trees, 0.23 for shrubs, and 1.17 for herbs in the studied forests of Eastern India. The total tree density was 1241 individuals per hectare, and Shorea robusta was the most dominant tree species that shared 40.12% of the total tree density. The total basal cover of the studied forests was quite low (18.93 m 2 ha −1), and S. robusta contributed the most (33.54%). Most of the species (89%) were distributed contagiously, while 11% were distributed randomly in the studied forests. No regeneration of most documented tree species (47.83%) and the low family richness is a matter of concern that signifies ...
Name the forests that are commercially most exploited in India.
Most exploited forest in India: • Tropical deciduous forests are India's most commercially exploited forests. • Tropical Deciduous Forests, also known as monsoon Forests, are the most common forests in India. • Hardwood trees such as sal, teak, neem, and shisha have been extensively utilised in tropical deciduous forests. • The wood harvested from the trees is used to make furniture, transportation, and building components. • Tropical deciduous woods are a prime location for extraction due to the existence of these resources. • Compared to other forests with comparable resources, transporting these resources through tropical deciduous woods is simpler. • Tropical deciduous woods are the best location for obtaining timber because of how easily it can be transported there.
These forests are commercially most exploited in India.
Q. With reference to Indian forests, consider the following pairs ___________. 1. tropical Moist Deciduous Forests Sandalwood: (Santalum album) 2. tropical Dry Deciduous Forests: (Shorea robusta) 3. tropical Thorn Forests: Shisham (Dalbergia sissoo) Which of the pairs given is/are correctly matched?
Which forests are most exploited? (2023)
Logging - tropical rainforests are cut down so that valuable trees like mahogany can be accessed and sold for timber to make furniture. Other trees are cut down for making paper products. Mining - the Amazon Basin is rich in natural resources such as iron ore, copper, tin, aluminium, manganese and gold. Humans have converted forest to agricultural and urban uses, exploited species, fragmented wildlands, changed the demographic structure of forests, altered habitat, degraded the environment with atmospheric and soil pollutants, introduced exotic pests and competitors, and domesticated favored species. Canopy is formed by the mass of intertwined branches, twigs and leaves of the mature trees. The crowns of the dominant trees receive most of the sunlight. This is the most productive part of the trees where maximum food is produced. The canopy forms a shady, protective “umbrella” over the rest of the forest. Burning fossil fuels also leads to air pollution, which kills an estimated 6.5 million people each year. Extracting oil can cause devastating spills in marine environments; extracting coal can destroy forests and other landscapes; and extracting natural gas can pollute waterways and cause earthquakes. The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines a...
