SURVEILLANCE IS ESSENTIAL TO PREVENT THE SPREAD OF WATER HYACINTH
In the sections considered to be clean of water hyacinth, the work of vigilance is being fundamental to avoid the propagation since in these sections small masses of this plant have been found festering in the river and nearby pools, proceeding to its immediate withdrawal. In this work ACECA collaborates with the surveillance in the section B avoiding the massive regrowth of plant and its introduction in Portugal.
The section affected by water hyacinth is reduced to just over seven kilometres, from downstream of the Zarza Bridge to Tijeras. The Guadiana Hydrographic Confederation is continuing the extraction work with a daily extraction team made up of 27 boats, 4 backhoes, 4 lorries and a tractor with a shovel as mechanical means and a team of around 100 workers.
Over the next few months it is planned to reinforce surveillance and extraction work on the stretches of residual presence on the banks or islands, paying special attention to possible seed sources that have been found in recent months.
