Asch. & Graebn., 1900 Résumé : Cortaderia selloana (Schult. & Schult. f.) Asch. & Graebn. (Pampas grass) is a perennial grass native to temperate and subtropical regions of South America. The species was introduced to western Europe for ornamental purposes during the nineteenth century, where it has become naturalized in anthropogenic and natural habitats, especially in sandy, open, and disturbed areas. Female plants of C. selloana produce thousands of seeds that are dispersed over long distances by wind and germinate readily. Its invasive success is also attributed to its ability to adapt and tolerate a wide range of environmental conditions, such as high salinity levels, long droughts, and soil chemical pollution. Cortaderia selloana usually invades human-disturbed habitats where it encounters little competition with other plants and high resource availability. However, the species can invade natural habitats, especially those with high light availability, causing biodiversity loss and changes in ecosystem functioning (e.g. alteration of succession and nutrient dynamics). The species may cause negative socio-economic impacts by reducing productivity of tree plantations, causing respiratory allergies, and decreasing the recreational value of invaded areas. Control costs are high due to the extensive root system that C. selloana develops and the high resprouting ability following physical damage. Although herbicides are effective control measures, their use is not allowed or is undesirable in all situations where the plant occurs (e.g. near riverbanks, natural protected sites). No biological control agents have been released on C. selloana to date, but the planthopper Sacchasydne subandina and the gall midge Spanolepis selloanae are promising targets.

Preemptive and proactive application of biological control for weeds: An argument for swifter action to aid conservation efforts / Melissa C. Smith in Biological control, 202 (2025)

Smith ; Kim Canavan ; Carey R. Minteer ; Deah Lieurance Année de publication : 2025 Article en page(s) : 105725 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Résumé : Invasive alien plants (IAPs) are a frequent consequence of global connectivity and present significant threats to biodiversity, amplifying impacts from global climate change and habitat loss. Integrated management efforts for landscape-level plant invasions often include some combination of mechanical, cultural, chemical, and biological control. The former three have well established protocols and development pipelines for rapid responses to new invasions. Biological control of IAPs, however, is often employed only after the invaded region has reached some arbitrary but intolerable level of negative impact that triggers efforts to develop agents to provide control. Despite mounting evidence that investments in prevention and proactive approaches to IAPs are the most cost effective, most expenditures, including those for biological control development, continue to be in the post-invasion reactive phase. We build a rationale for earlier investigation and implementation of biological control for IAPs. A potential framework for this approach would pair prioritization methods (e.g., risk assessments and horizon scanning) to identify targets with extensive literature searches for known herbivores or foreign range surveys and early host range tests. In addition, resource sharing among regions and nations with similar climates and risks would alleviate the onus of investment from any one party. Finally, investments into conservation and training opportunities between nations further incentivizes maintaining natural resources for potential biological control. By developing and implementing biological control earlier in or before the invasion process, countless impacts and costs are lessened.
