Species such as the golden apple snail are putting the agricultural sector in the Ebro river basin in quite a predicament. Meanwhile, in the southern part of the Iberian Peninsula, water hyacinths are threatening to destroy the natural ecosystem of the Guadiana River. Invasive species change not only the habitat of many other species but they also directly impact the region's economy. Some of these species are already wreaking havoc on certain areas but others could do so in the future and have a huge impact, both environmentally and financially.
