Species differentiation of Carabidae communities in Scots pine monocultures after using the complex-centre forest protection method
A three-year researches were conducted to assess the similarity of Carabidae communities on 3 plots differentiated in age, planned in „remises” of complex-centre forest protection method which are the patches of 5–12 ares with fell and broadleaved trees and shrubs, and in Scots pine stands as control. In remises as well as in control stand the most numerous species were: Pterostichus oblongopunctatus, P. niger, Carabus arvensis. Participation of forest species and large zoophags in remises increased with age. Margalef’s species richness indicator decreased with the age of plots. Distinct increase of mean individual biomass (MIB) was observed with the age increase of forest plots. Quick formation and development of the Carabidae communities depended on succession process of plants. Quicker growth of vegetation influenced quicker colonization by carabids species – typical for old stands. MIB value showed upward tendency and it was higher in forest plots, than in remises in the oldest variant of plots. Intensive fall of leaves in remises, and thus better fertilization of soil creates more appropriate living conditions for various animals.
