Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract Full Text

A review of the invasive alien species role in biodiversity loss and how to manage them coordinately at the national and international level.


In this article, we have tried to introduce "invasive alien species" and explain their environmental importance. Because of the similarity between plant pests, pathogens and weeds and invasive alien species, in terms of damage to plants, and environment, so the fight against these factors has been included in plant protection and quarantine duties, and "protection of the environment, forests and biodiversity against plant pests" has become one of the four main tasks of plant quarantine services. "Invasive alien species" (considered "Plant quarantine pests" under the International Plant Protection Convention, IPPC), invasive alien species have been identified as the second most important threat to biodiversity after "natural habitats destruction and loss ". Therefore, the Convention on Biological Diversity and IPPC, each consider themselves obliged to deal with "invasive alien species". Other mechanisms, such as Sanitary and Phytosanitary Measures, SPS, the Codex Alimentarius, and the Cartagena Protocol on Biosafety, are also effective one in strengthening plant quarantine and facilitating the invasive alien species management. In addition to these institutions, more than eight other international organizations, in the form of the Biodiversity Liaison Group (BLG), contribute to the protection of biodiversity resources. Finally, while explaining the role of BLG members, in the management of invasive alien species and environmental protection, we will discuss managerial interference and their effective synergy in achieving this important and vital purpose.
