今天，欧洲生物多样性的很大一部分依赖于低强度农业实践提供的栖息地，然而，随着欧洲农业的集约化，这种资源正在减少。在欧盟内部，特别是中部和东部的新成员国保留了相对大面积的物种丰富的农田，但尽管近年来在自然保护方面的投资有所增加，农田生物多样性的趋势似乎正在恶化。尽管中欧和东欧农田的高生物多样性价值早已被报道，但国际文献中关注该地区农田生物多样性的研究数量相对较少，欧盟共同农业政策内的措施也相对较差。在本意见研究中，我们认为，在欧盟首批东部新成员国加入10年后，中欧和东欧低密度农田在国际文献和欧盟政策中的持续代表性不足，阻碍了以证据为基础的合理保护干预措施的发展。现有的低密度农田对欧洲生物多样性的好处，特别是在中部和东部各州，应该在它们消失之前加以利用。现在需要的不是等待物种丰富的农田进一步减少，而是有针对性的研究和监测，为这些栖息地制定适合当地的保护策略。
A large proportion of European biodiversity today depends on habitat provided by low-intensity farming practices, yet this resource is declining as European agriculture intensifies. Within the European Union, particularly the central and eastern new member states have retained relatively large areas of species-rich farmland, but despite increased investment in nature conservation here in recent years, farmland biodiversity trends appear to be worsening. Although the high biodiversity value of Central and Eastern European farmland has long been reported, the amount of research in the international literature focused on farmland biodiversity in this region remains comparatively tiny, and measures within the EU Common Agricultural Policy are relatively poorly adapted to support it. In this opinion study, we argue that, 10years after the accession of the first eastern EU new member states, the continued under-representation of the low-intensity farmland in Central and Eastern Europe in the international literature and EU policy is impeding the development of sound, evidence-based conservation interventions. The biodiversity benefits for Europe of existing low-intensity farmland, particularly in the central and eastern states, should be harnessed before they are lost. Instead of waiting for species-rich farmland to further decline, targeted research and monitoring to create locally appropriate conservation strategies for these habitats is needed now.
