The translocation of orchids (Orchidaceae) cannot be successful if one is unaware of their effective pollinators and plant-pollinator interactions. is a generalized food-deceptive orchid, which is highly threatened in the Republic of Korea, thus, requiring immediate translocation actions. Although effective pollinators of the orchid are well known in China, little is known about the pollinators in the Republic of Korea and the ecological context in which the orchid can be successfully pollinated. To briefly assess the pollination of prior to translocation, we conducted a one-month survey of general pollination and the community-wide plant-pollinator network properties. Over 21 h of observation, we found that an effective pollinator of the orchid was the sweat bee . The network was significantly specialized and modular, but not significantly nested. (pollinator) and (plant) were determined to be keystone species, based on network metrics. A total of six network modules were identified and the flower colors of the plant species belonging to the module were purple, white, and yellow. After comparing the daily network patterns, we found that pollination of the orchid was accomplished when various flowering plant species bloom, and the nestedness value was high. This study revealed that high plant and pollinator richness could increase the chance that the deceptive orchid would be pollinated. Our study suggests that the network properties of this food-deceptive orchid community could provide useful insight into understanding the ecologically suitable habitat for the translocation of the highly threatened orchid species .
如果不了解兰花（兰科）的有效传粉者以及植物与传粉者之间的相互作用，兰花的迁地保护就不可能成功。[具体兰花名称未给出]是一种广义的食源性欺骗性兰花，在韩国面临高度威胁，因此需要立即采取迁地保护行动。虽然这种兰花在中国的有效传粉者已为人熟知，但在韩国，关于其传粉者以及兰花能够成功授粉的生态环境却知之甚少。为了在迁地保护之前简要评估[具体兰花名称未给出]的授粉情况，我们对一般授粉情况以及整个群落范围内的植物 - 传粉者网络特性进行了为期一个月的调查。经过超过21小时的观察，我们发现这种兰花的有效传粉者是汗蜂[具体汗蜂名称未给出]。该网络具有显著的特异性和模块性，但嵌套性不显著。根据网络指标，[传粉者名称未给出]（传粉者）和[植物名称未给出]（植物）被确定为关键物种。总共识别出六个网络模块，属于[模块名称未给出]模块的植物物种的花色为紫色、白色和黄色。在比较了每日的网络模式后，我们发现当各种开花植物物种开花时，这种兰花的授粉得以完成，并且嵌套性值很高。这项研究表明，高植物和传粉者丰富度可以增加这种欺骗性兰花授粉的机会。我们的研究表明，这种食源性欺骗性兰花群落的网络特性可以为理解高度濒危兰花物种[具体兰花名称未给出]迁地保护的生态适宜栖息地提供有用的见解。
