The invasive potential of Elaeagnus angusti folia in the natural pastures of the Rio Negro Valley,Argentina
Elaeagnus angusti f olia L.(Russian olive, Narrow leaved oleaster) is a deciduous tree that grows mainly in the summer.It was introduced as an ornamental into the Middle Valley of the Rio Negro, Argentina (39°30′ S ; 65°30′W), and has become naturalized in extensive regions along the river margins.This invasive species is threatening the biodiversity, structure and function of the ecosystem in areas fully occupied by natural vegetation.When the first small plant patches appeared in 1970, they were left unnoticed or not considered as an invasive, harmful species by land managers.Therefore, no control methods were applied.The land surrounding the river is utilized for livestock breeding using the natural grassland as the main food source for animals.In the invaded areas, changes of species composition seriously impaired the meat industry.
