Rhamphicarpa fistulosa, widespread specie of wetlands, is a hemiparasitic weed occurring in lowland rice production. It was distributed in Africa, Madagascar, Australia and India. To know more about the habitat of Rhamphicarpa fistulosa in Senegal, we addressed two questions: (1) which plant species are indicators of the presence of R. fistulosa? (2) What are the ecological variables which predict the presence of R. fistulosa? Three agroecological areas were identified following the main lowland rice production. The results showed that Althernanthera sessilis, Echinocloa colona, Aeschynomene indica and Cyperus haspan combined with the ecological variables such as the pH the presence of the host (rice crops) and the bare soil are indicators of the presence of R. fistulosa. It was also appeared that Rhamphicarpa fistulosa is following rice production in the colonization of new habitat. Habitat occupied by R. fistulosa should be recognized as relict and critically endangered sites where special protection measures must be used. They should be included in the environmental monitoring program with local active protection.
