The influence of enclosed fallow deer’s on soil chemical properties

Abstract

Introduction of new species could have risk for stability of ecosystems, populations and communities. Herbivores can have important direct and indirect effects on belowground properties and processes that govern ecosystem structure and productivity. A few studies about influence of fallow deer on soil chemical properties were performed. In this study, we examined the effects of fallow deer kept in enclosures on soil chemical properties. The study was carried out in enclosures of Anyksciai, Panevezys, Kaisiadorys and Raseiniai State Forest Enterprises. Spruce, mixed spruce and birch stands dominated in enclosures. The significant effect of fallow deer on soil nitrogen has the potential to reduce ecosystem productivity. We collected soil samples (0-20 cm soil layer) in enclosures and in near-by stands outside enclosures as control. We measured pH, total nitrogen, mineral N-NH4+, N-NO3- and mobile phosporu. The aim of the study was to examine influence on soil chemical properties
