The present communication deals with the morpho-taxonomic enumeration of 28 species of Comarium from Mani Pokhar Pond of Jashpur District in Chhattisgarh. All these species have been recorded for the first time from this part of the state.

A study was conducted in different forests of districts of Rudraprayag and Pauri (Uttarakhand) in the Central Himalayas for determining the physical and chemical features of soil. The findings indicated that there was more accumulation of minerals in the undisturbed forests irrespective of disturbed forest type.

The changes undergone by physico-chemical properties of soil, profile morphology and the productivity index, as a result of bringing the barren land under Poplar plantation, were evaluated in Yamuna Nagar District of Haryana, where large chunks of land have been raised as block plantation with Poplar. The soils supporting Poplar plantations were enriched with organic carbon and nutrients.
