A great number of farmland wildlife species has shown a sharp population decline in European countries, mainly caused by changes in agricultural practices leading to habitat alterations. Within this scenario, the identification of agricultural practices providing economic benefits to farmers and, at the same time, favoring higher biodiversity levels is a key challenge. This is especially interesting in Mediterranean livestock farming environments where bird numbers decrease due to intensification. Aiming at assessing the benefit to biological diversity of certain types of management practices in grasslands, we experimentally planted enriched pastures. Through a monitoring program of the bird and arthropod communities performed in Extremadura (W Spain) during 2 years (2016–2018), we compared relative richness of birds, abundance, and density values of birds and arthropods between treatment (three plots with enriched pastures) and control areas (six plots of natural grasslands). We found that enriched pastures had higher levels of relative abundance and density of wildlife with respect to natural grasslands and provided a greater variability and availability of trophic resources to birds. Habitat use by birds and arthropods not only depended on the type of pastures but also on the season, the study area, the presence of livestock and the vegetation height. Sowing enriched pastures constitutes a proactive measure stimulating biodiversity in Mediterranean extensive livestock farms that is also beneficial at the socioeconomic level. Therefore, co-financing this measure within the framework of subsidies from the Common Agricultural Policy of the European Union, as well as its inclusion in the future operational programs approved by the authorities, are essential.

在欧洲国家，许多农田野生动植物物种显示出人口急剧下降，这主要是由于农业生产方式的改变导致栖息地的改变。在这种情况下，确定可为农民带来经济利益并同时有利于提高生物多样性水平的农业做法是一项关键挑战。这在地中海牲畜养殖环境中特别有趣，在这种环境中，鸟类的数量因集约化而减少。为了评估草地上某些管理方式对生物多样性的益处，我们通过实验种植了丰富的牧场。通过对埃斯特雷马杜拉（西班牙西部）在2年（2016-2018）进行的鸟类和节肢动物群落的监测计划，我们比较了鸟类的相对丰富度，丰富度，处理（三个拥有丰富牧场的地块）和控制区域（六个天然草原的地块）之间的鸟类和节肢动物的密度和密度值。我们发现，相对于天然草原，富裕的牧场具有相对较高的野生生物相对丰度和密度，并为鸟类提供了更大的变异性和营养资源。鸟类和节肢动物的生境利用不仅取决于牧场的类型，还取决于季节，研究区域，牲畜的存在和植被高度。播种丰富的草场是一种积极措施，可以刺激地中海广泛的牲畜养殖场的生物多样性，这在社会经济层面上也是有益的。因此，在欧盟共同农业政策的补贴框架内共同资助这项措施，
