The Obedska Bara Special Nature Reserve is one of the oldest protected areas in the world, also enlisted as an Important Bird Area, Ramsar and UNESCO world heritage site. False indigo bush (Amorpha fruticosa L.) represents an invasive alien species which is significantly deteriorating the biodiversity of the Obedska Bara Special Nature Reserve in Serbia. Mapping of A. fruticosa, using an unmanned aerial vehicle and GIS tools, showed that in meadows, pastures, ponds and wetland areas, A. fruticosa covered 85 ha or 11% of the area. However, coverage was uneven, and the most overgrown areas were some meadows (up to 35%), while flooded areas and areas where human impact is significant, as on pastures, were not so affected (1-3%). The most susceptible parts were forest edges. Active management practices, such as cattle grazing and topsoil tarping, and occasional moving, gave positive effects in A. fruticosa, but also other invasive terrestrial plant species spreading control in the reserve. This has also been confirmed by the UAV survey and mapping, which has proven to be an effective method for A. fruticosa monitoring over large areas.
奥贝德斯卡巴拉特殊自然保护区是世界上最古老的保护区之一，也是重要鸟类区、拉姆萨尔湿地和联合国教科文组织世界遗产地。假靛 Bush（Amorpha fruticosa L.）是一种入侵的外来物种，它严重恶化了塞尔维亚奥贝德斯卡巴拉特殊自然保护区的生物多样性。利用无人机和 GIS 工具对 A. fruticosa 进行测绘显示，在草地、牧场、池塘和湿地地区，A. fruticosa 覆盖了 85 公顷，占该地区的 11%。然而，覆盖情况不均匀，过度生长的地区主要是一些草地（高达 35%），而受洪水影响和人类活动影响较大的地区（如牧场）则没有受到那么大的影响（1-3%）。最易受影响的地区是森林边缘。积极的管理措施，如牛放牧和表土覆盖，以及偶尔的移动，对 A. fruticosa 以及保护区内其他入侵的陆生植物物种的扩散控制都产生了积极的影响。这也得到了无人机调查和测绘的证实，证明了这是一种对大面积 A. fruticosa 进行监测的有效方法。
