Abstract:

The aim of the study was to determine the relation between landscape structure, point counts number and the number of breeding bird species occuring in different types of farmland. Species number was evaluated using point counts on six plots localised in Polish and German farmland (from 30-52 points/plot, 10 min/point, radius - 100 or 150 m). The equation: S = cAz, where S - species number, A - sample size (number of points), c, z - parameters, was used to test the relation between point counts number and species numbers. The coefficients of determination amounted to 0.95-0.99. Among the parameters of equation, c was more strongly correlated with landscape parameters (e.g. wood cover). The analysis revealed, that unified farmland requires bigger representative sample size compared to other, more diversified types of farmland. At least 50 points are needed for proper comparing bird species number between farmlands or periods.
