This paper deals with the first results of two sycamore group planting experiments established in the training forest enterprise Křtiny (South Moravia, Czech Republic). The Soběšice II plot, established in 2013, compares group planting (17 seedlings; patches of 7.1 m2) to whole-area planting. The Tipeček experiment, established in 2015, compares the whole area sycamore planting to sycamore group planting created by sixteen sycamores (spacing 1,4 m × 1,4 m) introduced into the gaps of young birch stands. Treatment of whole-area planting on Tipeček was fenced, and the sycamore group planting was protected partly by a repellent and partly by a treeshelter. For the same plot, modeling of regeneration costs was performed differing in method of planting and in game prove protection. Results from the Soběšice II plot were ambiguous. Sycamore in the Tipeček plot grew the best in the whole-area plating treatment; the slowest growth and the highest number of forked trees was observed in groups where planting was protected by repellent. Modeling of regeneration costs supports hypothesis that group planting is considered a low costs regeneration method. The present use of group planting method is also restricted as a consequence of damage caused by game population.
