Abstract
The paper deals with the biomass and productivity of sal (SF) and miscellaneous forests (MF) of Satpura plateau (Madhya Pradesh) India. These forest types were divided into four sites namely open miscellaneous (OMF, site-I), closed miscellaneous (CMF, site-II), open sal (OSF, site-III) and closed sal (CSF, site-IV). The degree of disturbance followed the order: III (0.70) 109 (III) > 79.80 (I) > 52.69 (II), while for NPPherb, the order of importance was, 109.50 (IV) > 73.27 (I) > (II), 71.75 (III) > 55.71 (II). NPPtotal was highest for closed forest stands than of the open ones. NPPteak was lower for high-disturbed site than of the less disturbed site. Photosynthetic/ non - photosynthetic ratio follows the order: 0.067 (II) > 0.030 (III) > 0.026 (IV) > 0.018 (I). Open forests showed lower values for this ratio. NEP was higher for SF than of the MF. Further closed forests showed higher values of NEP. OSF showed lower values of NEPsal than of the CSF. Disturbances in open forests not only reduced stand biomass of tree species, dominant species in particular, but also declined the tree productivity. So, gap filling plantation in side the forest is suggested to improve the productivity of open forests.
Highlights
Satpura plateau is a wide table land stretching from Maikal range in the east to Nimar in the west
The higher above ground tree biomass was produced by MF than of sal forests (SF)
The study area is located in Chhindwara district of Madhya Pradesh (India)
Summary
Satpura plateau is a wide table land stretching from Maikal range in the east to Nimar in the west. It covers Chhindwara, Betul, Seoni, Hosngabad and Balaghat district of Madhya Pradesh (India). The tribals are mostly Jharias and Gond They mostly depend on these forest for their livelihood. Most of the studies have been carried out on biomass estimation and productivity in different types of forest ecosystems [2,3,4,5,6,7,8].
