2002年、2003年和2004年对英国赫里福德郡的两片芒草和两片芦苇金丝雀草田进行了野生动物监测，以调查多年生生物量草类作物对地面植物、小型哺乳动物和鸟类的生态影响。样方用于记录每种作物内部和周围的地面植被覆盖百分比。使用朗沃斯诱捕器通过活体诱捕的方式对小型哺乳动物进行取样。常见的鸟类普查技术用于监测鸟类数量。芒草田比芦苇、金丝雀草或耕田的杂草植被更丰富。鸟类对生物质作物田的利用因物种而异。芒草丛中的云雀 (Alauda arvensis)、田凫 (Vanellus vanelliits) 和草甸鹨 (Anthus pratensis) 等露天鸟类种类比芦苇金丝雀草田中的数量要多得多。小型哺乳动物物种没有特别的作物类型偏好，而是偏好良好的地面覆盖和很少的土地干扰，这是由两种生物质作物提供的。在田地边缘和边界内发现的地面植物群、小型哺乳动物和大多数鸟类（露天鸟类除外）比在农田中更为丰富，这表明在种植生物质作物时保持田地结构的重要性。芒草工作完全涉及青苗作物，如果大面积种植根茎，这些作物可能代表全国农作物的一部分。当前项目的研究结果表明，由于农业管理系统的低强度和未经处理的岬角，多年生生物质禾本科作物可以为多种形式的本土野生动物提供显着改善的栖息地。 (c) 2006 Elsevier Ltd. 保留所有权利。
Wildlife monitoring of two miscanthus and two reed canary-grass fields in Herefordshire, England was carried out in 2002, 2003 and 2004 to investigate the ecological impact of perennial biomass grass crops on ground flora, small mammals and birds. Quadrats were used to record percentage ground vegetation cover within and around the periphery of each crop. Small mammals were sampled by live trapping using Longworth traps. The common bird census technique was used to monitor populations of birds. Miscanthus fields were richer in weed vegetation than reed canary-grass or arable fields. Bird use of the biomass crop fields varied depending on species. There were considerably more open-ground bird species such as skylarks (Alauda arvensis), lapwings (Vanellus vanellits) and meadow pipits (Anthus pratensis) within miscanthus than within reed canary-grass fields. There was no particular crop-type preference by the small mammal species, but rather a preference for good ground cover and little land disturbance, which was provided by both biomass crops. Ground flora, small mammals and most of the bird species (except open-ground birds) were found more abundantly within field margins and boundaries than in crop fields indicating the importance of retaining field structure when planting biomass crops. The miscanthus work relates entirely to young crops, which may be representative of part of the national crop if large areas are cultivated for rhizomes. The findings from the current project indicate that perennial biomass grass crops can provide substantially improved habitat for many forms of native wildlife, due to the low intensity of the agricultural management system and the untreated headlands.
