||Alien species can have major ecological and socioec- onomic impacts and so effective management are needed. In this perspective, one increasingly seeks to involve end users, such a recreational users (Shackle- ton, Adriaens et al. 2019). Recreational users may share valuable knowledge about the ecological eco- systems at stake. They have time, materials and money to afford. In the literature, several studies have looked at factors that increase user involve- ment highlighting the effect of variables such as e.g. perceptions, information, or education. Neverthe- less, these behaviors are often studied separately or, conversely, grouped into a single category called “pro-environmental behaviors” (Halpenny 2010). Without excluding the possibility of common factors affecting these behaviors, we consider that behav- iors are not necessarily homogeneous. In particular, the nature of the operations to be carried out may be very important (Niemiec, Ardoin et al. 2017, Pa- gès, Fischer et al. 2019). This is what we study in de- tail in this paper.
