Effects of canopy gap on soil macrofauna in mixed beech stand (case study in shast- kalate forest)

The soil macrofauna are the most important terriocolous (invertebrates) section in small and micro and trummage in the them، on the other hand، the creation of pores and increases soils، porosity are a very important role it، also change method tending of north forests to single selection system، individual trees is done، that result creation canopy gap. Also throught the trees to mark، trees breeding stand and regeneration will be created، so the most important stage، interference human in the forest stand. This study was conducted wether soil macrofaunabiodaiversity under canopy with canopy gap in soil layers. Diversity soil macrofauna including earthworm، diplopoda and chilopoda were extracted 10×10×10 cm soil by hand-sorting procedure. Diversity (shanon H index) and evenes (smith-willson) were analyzed using. Results show that there are significant differences between groups under canopy with groups’ canopy gap hence biodiversity indicators in 99% level
