مستخلص: The study aimed to determine the above-ground biomass (AGB) of tropical deciduous forests in Central India using field-based techniques and spaceborne quad-pol ALOS PALSAR-2 L-band and dual-pol Sentinel 1A C-band synthetic aperture radar (SAR). Field sampling based on 73 forested grids exhibited a diverse forest composition in the Satpura Tiger Reserve (STR) with a total of 54 tree species of which 31.48% species were IUCN Red-Listed. The forests were highly diverse (H′=3.22) with a low concentration of dominance (CD = 0.06) and a quite high species evenness (E = 0.81). The sensitivity and correlation between field-based AGB and SAR backscatter in STR were highest in cross-polarization due to its higher sensitivity to the vegetation structure in both L- and C-band SAR, where L-VH based AGB estimates were found more accurate (RMSE:5.17%). The study provided vital information for setting up strategies for biodiversity conservation, enhancing forest productivity, and restoring wildlife habitats. [ABSTRACT FROM AUTHOR]

مستخلص: The article presents a study which examines the microenvironmental characteristics of Arundinaria maling's natural habitat in Arunachal Pradesh, India. A. maling, which is a rare and endemic bamboo species in Arunachal Pradesh, is used for house construction, handicrafts, fencing, and support for agricultural and vegetable crops. The climatic and edaphic characteristics of this species are determined. Results of the study show the need to develop conservational strategies for the use of A. maling.
