S. aUtilization of Collembola in the avaliation of two recovery models of degraded areas. c2008 aThe objective of this study was to evaluate the difference between two recovery models of degraded areas proposed by Aumond (2007). The evaluation was performed by examining the invertebrate?s fauna composition since the efficiency of the recovery projects is almost not evaluated and the use of wildlife for that is neither considered. The study area is located in the municipality of Doctor Pedrinho in Santa Catarina state, Brazil located at 300 m elevation in the basin of the river Benedito at the Medium Itajaí Valley. The area was divided in four plots. Two regular where the ground was plain and two irregular with wells made approximately 1 m wide, 1.5 m long and 0.5 m depth. For each kind of plot there were two different sizes: 820 m2 planted with 392 seedlings of bracatinga - Mimosa scabrella Benth (Mimosaceae) and 1110 m2 planted with 477 seedlings of bracatinga. The collection of invertebrates was done using Möericke traps, - white and yellow trays, containing a solution of 1,000 ml of water, 500 ml of 70% alcohol and drops of detergent. Traps glue panel type, blue and yellow placed inside the plots at one meter high were also utilized. The samples were collected monthly, totalizing 10 samples. Four zoological Classes, 23 Orders and 1 Sub-order were identified. The Order Collembola was 100% present in all samples at the different plots types. This order was also found in the Möericke traps and glue panels. The Collembola frequency was 9.21% in yellow Möericke traps, being the fifth most frequent order in this trap type. In the white trays the frequency was 14.61% being the fourth most frequent order. For the glue panel traps, the Collembola did not appeared among the most frequent orders, presenting a frequency of only 2.78% and 4.49% respectively for yellow and blue panels. Greater number of individuals was collected in the regular plots than in the irregular in the white traps compared with the yellow ones; and in the yellow cards in relation to the blue cards. The higher humidity and lower soil temperature recorded in the regular plots (Aumond, 2007), associated with greater quantity and diversity of growing vegetation may suggest the presence of a climate more suitable to the establishment of Collembola. Results indicated that the presence of a greater number of individuals in the regular plot was related to the increased soil moisture and that the smaller number of Collembola found in the irregular plots indicated a relationship with a more advanced vegetative stage when compared to the regular plots.1 aVITORINO, M.
