Abstrakt: Abstract: a_1Abundance of ten species of Collembola was studied in spruce forests in the High Tatra Mts. damaged by severe wind in November 2004, viz. Anurophorus cuspidatus Stach, 1922, Anurophorus laricis Nicolet, 1842, Desoria duodecemoculata (Denis, 1927), Folsomia penicula Bagnall, 1939, Friesea mirabilis (Tullberg, 1871), Isotomiella minor (Schäffer, 1896), Parisotoma notabilis (Schäffer, 1896), Protaphorura armata (Tullberg, 1869), Protaphorura aurantiaca (Ridley, 1880) and Tetracanthella fjellbergi Deharveng, 1987. The aim of this study was to compare the abundance of dominant species at the different sites and assess the possible reasons for the differences. The study was carried out in three differently managed stands: an undamaged forest stand (control site, REF), windthrow forest stand with harvested fallen wood (EXT), and unmanaged windthrow forest stand left to natural succession (NEX). Soil samples were taken in spring and autumn in 2005, 2006 and 2007. At each locality 3 different plots were sampled. Material comprised a total of 5,434 specimens. Based on the effect of different management treatments the species may be sorted into four groups: (1) species that were most abundant at REF stands and less abundant at both NEX and EXT stands (D. duodecemoculata, F mirabilis); (2) species that were most abundant at REF and NEX stands, and significantly less abundant in EXT stands (F. penicula, T. fjellbergi); (3) species that were most abundant at EXT stands and very much less abundant at both REF and NEX stands (A. cuspidatus, P. aurantiaca); (4) species that did not differ in abundance in the three treatments (I. minor).
