Sažetak
Silvicultural activities such as thinning are crucial for development of quality and healthy high forests, but in coppices of Lika region they are neglected due to high cost, lack of manpower and other limitations linked to terrain features (e.g. high slopes, rocky terrain), low number of forest roads, etc. Extent of expert knowledge and available research results on influence of thinning regimes on coppices have been limited so far, but there are initial results pointing into direction of significant benefits of thinnings on composition, quality and growts of Lika coppices. Paper presents results of comparative research on the influence of thinning in three different types of coppices (typical coppice, coppice with standards, coppice in transition phase – beech and sessile oak dominated stands). A set of trial plots was established in previously thinned vs. unthinned coppices (research initiated already in 2002) on three localities (FA Gospić, forest administration Perušić). Activities are initiated under the project funded by Croatian Forests Ltd. and led by Croatian Forest Research Institute under the title “Issues of coppice management in FA Gospić”. Trial plots and trees have been permanently marked with unique plot/tree numbers, first measurements have been done (tree species, d1, 3, total tree heights, tree/stem origin, number of stems per stump) as well as assessment of tree/stem quality (6 features). A total of 1.404 trees (have been marked and measured, while a total of 5 trial plots (50 x 50 m) established on the area of 1, 25 ha. Descriptive statistics and ANOVA have been done with STATISTICA 8.2, StatSoft Inc. 2007. Preliminary statistical analysis reveals clear difference between treatments (thinning, control) and underline beneficial influence of thinnings on tree growth on all trial plots, which supports inicial results aquired in this area. In the course of the project repeated measures will be conducted to analyse DBH, tree heights increment per tree and treatment, but further research and monitoring will be needed.
