尽管生物入侵是一个世界性的现象，造成重大的生态，经济和人类福利的影响，有有限的了解环境管理人员如何看待这个问题，并随后管理外来物种。西班牙的环境管理人员进行了调查问卷，以（1）分析在何种程度上，他们认为植物入侵作为一个问题;（2）确定的地位，发生，和有害外来植物物种的影响;（3）评估目前的努力和支出针对外来植物管理;和，最后，（4）确定他们使用的标准，以确定管理的优先事项。与其他环境问题相比，植物入侵被认为是只有适度的问题和机械控制是最有价值的和经常使用的策略，以科普在西班牙的植物入侵。根据收到的70份调查问卷，193个物种被认为是有毒的，其中109个是管理活动的对象。超过90%的物种在至少一个保护区内被发现。据答复者称，最经常管理的物种在各行政区域分布最广，被认为造成的影响最大。影响的感知似乎与它们的入侵状态无关，因为只有一半被确定为有害的物种被认为是西班牙的入侵物种，而43%的物种被认为只是偶然的外来物种正在造成高影响。管理费用的记录很差，少数数据表明，实际支出总额为50 492 437 a，在过去十年中没有迹象。大多数答复者指出，由于经济资源有限、缺乏公众意识和支持以及不同公共行政部门之间缺乏协调，管理措施不足以控制外来植物。管理人员还表示关切的是，许多科学研究关注的是外来植物的生态，而不是管理外来物种的具体成本效益战略。
Despite biological invasions being a worldwide phenomenon causing significant ecological, economic, and human welfare impacts, there is limited understanding regarding how environmental managers perceive the problem and subsequently manage alien species. Spanish environmental managers were surveyed using questionnaires to (1) analyze the extent to which they perceive plant invasions as a problem; (2) identify the status, occurrence, and impacts of noxious alien plant species; (3) assess current effort and expenditure targeting alien plant management; and, finally, (4) identify the criteria they use to set priorities for management. In comparison to other environmental concerns, plant invasions are perceived as only moderately problematic and mechanical control is the most valued and frequently used strategy to cope with plant invasions in Spain. Based on 70 questionnaires received, 193 species are considered noxious, 109 of which have been the subject of management activities. More than 90% of species are found in at least one protected area. According to respondents, the most frequently managed species are the most widespread across administrative regions and the ones perceived as causing the highest impacts. The perception of impact seems to be independent of their invasion status, since only half of the species identified as noxious are believed to be invasive in Spain, while 43% of species thought to only be casual aliens are causing a high impact. Records of management costs are poor and the few data indicate that the total actual expenditure amounted to 50,492,437 a,not sign in the last decade. The majority of respondents stated that management measures are insufficient to control alien plants due to limited economic resources, lack of public awareness and support, and an absence of coordination among different public administrations. Managers also expressed their concern about the fact that much scientific research is concerned with the ecology of alien plants rather than with specific cost-efficient strategies to manage alien species.
