Abstract The aim of this study was to determine the enzymatic activity (dehydrogenase and urease) in trophically diverse Brunic Arenosols and Cambisols. Efforts to establish the relationship between enzymatic activity and physico-chemical properties of various subtypes of Brunic Arenosols and Cambisols were attempted. Another aim was to determine the effect of vegetation on the properties of soil surface levels. The study was conducted on 94 plots located in nature reserves and national parks in the Polish lowland area. Dehydrogenase activity and urease showed large variations in the subtypes of the distinguished Brunic Arenosols and Cambisols. Dehydrogenases and urease activity in surface layers of fresh humus of Cambisols and Brunic Arenosols was strongly associated with the plants. This is confirmed by the relationship between the enzymatic activity and the type of accumulated humus substances, the ratio of carbon to nitrogen and humus horizons reaction.

Mangrove Degradation

The coast of Henry's island, extending from Saptamukhi River in the east to Bakkhali River in the West. In the hot and humid climate of the Sundarban, a negligible input of fresh water through tidal creeks, high evaporation rate at the surface area are the probable reasons behind the evolution of Hypersaline patches of Henry's and Patibunia Island. The dense salt patches develop in the abandoned portion of the surface then sinks and move out of the tidal estuaries as subterranean flow or a bottom current to make the environment more saline. Development of Saltpan is one of the major hindrances for the growth of mangroves and hampers the ecological balance of Sundarban. Present paper attempts to highlight- I) To study and identification of Geomorphological settings of both island. ii) Analysis of Physico-chemical properties of hyper saline soil. iii) Identification of hyper-saline patches and their impact on mangrove degradation. Application of remote sensing technique and GIS analysis help to find out the relationship between mangrove degradation and salinity within the islands area in the last few decades. Development of hyper saline patches and changing environmental parameters are how much responsible for the mangrove degeneration process are major issues of this paper. The Forest Department has attempted to restore the growth of mangrove and improve fragile ecosystem but without understanding the geomorphology and environmental condition, it is not possible to implement proper managemental strategies for wetland restoration process.
