Abstract

Mortality of fir (Abies pindrow) and spruce (Picea smithiana) in Chakrata Forest Division (U.P.) has taken plnce following the heavy fellings carried out during 1941 to 1950. Mention has been made of some of the important observations made by the previous workers. The different geological formations occurring under these forests have been described. An attempt has been made to correlate the mortality of these species with the nature, type and structural features of the underlying rock formations.

Abstract

Quantitative and qualitative mineralogical studies were carried out on soil samples collected from North Bihar afforestation areas, especially those of Champaran District. The data on mineralogical composition of fine sand fractions of the soils bearing poor as well as good stands of forest plantations have been presented and discussed in order to gain more complete knowledge of the mineral reserves and to correlate the same with the growth status. In general, the light minerals form the bulk of the suite. The proportion of garnet is the highest among the heavy, minerals. From the general assemblage the minerals appear to be mosty, characteristic of the metamorphic rocks. Apparently, no direct correlation between the mineral content and the growth status was observed.
