Exotic plant takes over dunes of Southern Spain
Date:3/29/2010

Introduced more than 40 years ago, Galenia pubescens, an exotic plant from South Africa is found in great numbers in altered coastal environments in the south of Spain. Since its impacts on the ecosystem are unknown, a Spanish research team has studied its invasive capacity. The conclusions of this study show that, although populations of this plant are still at incipient levels, effective control is needed to prevent this "potentially" invasive plant from having more serious impacts.

In order to be able to predict the invasive success of this plant and identify coastal areas at greatest risk, the scientists evaluated its capacity to invade the coasts of Andalusia, in southern Spain. The results were clear: "Galenia pubescens is a potentially invasive plant and should be included in the national catalogues of invasive plants", Juan Garca-de-Lomas, lead author of the study and a researcher in the Biology Department at the University of Cadiz, tells SINC.

The research team, which has published its conclusions in Acta Oecologica, also points out that dunes are more vulnerable than marsh areas, since the plant produces more seeds in grows better on dunes.

"The impacts of this plant show a clear decline in the wealth and diversity of other plants in the invaded sites compared with control sites (not invaded), as well as a change in functional types (increase in wasteland plants, which develop and live in areas of human habitation or along communication lines) and a loss of perennial plant types", says Garca-de-Lomas. The scientist says these impacts will mean "a longer recovery period for ecosystems once this plant has been eliminated".

The researchers also found that the dense carpets of Galenia generate "very significant shade covering". This limits the ability of native seeds and young plants to germinate and develop, and causes changes in the features of the soil, for example acting as a brake on
