Abstract

Aim of this research was an evaluation of renovation of mid-forest meadows, on which different renovation methods were applied, based on yielding and sward ttractiveness measured by red deer biomass intake.Studies on ethology of red deer wild-living population on renovated mid-forest meadows has been started in epartment of Grassland and Natural Landscape Sciences of PULS in 2013. For this purpose, two experiments on mid-forest meadows located on Polanów Forestry District (RDSF Szczecinek) territory was established. Experiment includes different methods of renovation – overdrilling and full tillage, combined with sowing of three types of meadow mixtures suitable for red deer – two available on the market (Blühende Wildäsung – M1 and Weidgreen Hochwildweide – M2) and one author’s Mixture (M3). As reference for each experiment the control surface without renovation was used. To estimate sward yielding and red deer sward intake, caged grazing exclosures made of wire mesh, with size of 2 m x 2 m, were placed on every experimental plots. Sward yielding assessment was based on samples manually harvested from area 0.5 x 0.5 m inside the cages. The same procedure was conducted in reference point at the distance of 3–4 meters from the cages. Research was carried out in three terms. To determinate dry matter content, collected samples were dried in laboratory conditions. Yield of every experimental treatment was given regarding to dry matter content for samples from inside of caged grazing exclosures. Sward attractiveness for red deers was expressed as sward intake given in percent, calculated as difference between yield from cages and from grazing areas.Highest average dry matter yield of sward for three investigation terms was notice on experimental treatment including full tillage sown with mixture M1 – (Blühende Wildäsung) – 4940 kg ha –1 DM, followed by M2 (Weidgreen Hochwildweide) – 2986 kg ha –1 DM and author’s mixture M3 – 2295 kg ha –1 DM. Average yield on overdrilled areas was 2078 kg ha–1 DM and on control surface – 2037 kg ha –1 DM. Highest average sward intake was also recorded on mixture M1 – 59.1%, subsequently on author’s mixture (M3) – 42.3% and M2 mixture – 37.7%. Relatively low sward intake was afforded on overdrilled areas – 17.9% and the lowest on control surface – only 8.6%.
