Fallow management increases habitat suitability for endangered steppe bird species through changes in vegetation structure

In the face of the dramatic worldwide decline of farmland bird populations, the preservation of fallow fields is a conservation measure encouraged through subsidies (e.g. agri‐environmental schemes, AES). Beyond the general benefits of increasing fallow availability for endangered steppe bird populations, there is a lack of knowledge on how fallow management can contribute to meeting species‐specific habitat requirements. We used occurrence data from three steppe bird species protected at the EU level (Stone Curlew Burhinus oedicnemus, Little Bustard Tetrax tetrax, and Calandra Lark Melanocorypha calandra), framed in a quasi‐experimental approach covering an unprecedented spatio‐temporal scale that included 612 fallow fields over a three‐year study period in an agricultural Mediterranean landscape (Spain). We used path analysis to explore the mechanisms by which common agricultural practices affected species‐specific occurrence. We examined partial effects of agricultural practices o...
