The Corncrake colonizes usually mountain grasslands used for hay-cutting. The goal of this work is to characterize effect of three landscape elements – constructions, forest, and roads – on localization of calling corncrake males. From 2011 to 2015 I studied the distance of calling males (n = 192) from nearest forest edge, building and nearest road. ANOVA model containing type of landscape element and year in interaction explained 21.1% of the variability of observed males’distances from the three landscape elements. The results showed that calling males were statistically significantly located closer to forests or roads but further from constructions. The year of observation did not affect the results. Thus as the largest risk for the occurrence of species we may consider the development of new constructions in an agricultural landscape. For that reason, it can be important to consider carefully every construction in Special Protection Areas designed for Corncrake as the fragmentation of favourable areas and habitats can cause irreversible damage to local population.
