Description

This study seeks evidence of benefits to farmland birds of reversing land use intensification on and among arable fields and to what extent benefits are moderated by presence of more natural habitats (semi-natural pastures and field borders). The study compares bird numbers for a set of farmland bird species in landscapes/sites differing in agricultural land use and amount of semi-natural habitats. The dataset is comprised of bird counts and agricultural habitat characteristics from a set of 1km radius circular landscapes distributed in the most to medium productive regions in Scania (southern-most province of Sweden). Study sites (landscapes) where selected to maximise orthogonality in the habitat characteristics. Bird counts in each landscape where made for 5 min. at 11 – 16 points distributed in a 4 by 4 grid (approx. 400 m between points; half the points, “columns” 1 and 3, where moved to nearest field border; points more than 50 m outside farmland where discarded; points that could not be accessed (gardens etc.) where moved to nearest access point). Landscapes were visited twice (>= 1 wee
