Exotic plants brought to the Netherlands by people are rapidly spreading through the country, according to Statistics Netherlands on Friday. Water plants in particular are causing problems in Dutch waterways. According to calculations by the statistics office, these so-called invasive alien plant species are present in 160 "kilometer grid squares" - areas of one kilometer by one kilometer. Before 1997 there were only invasive plants in 25 grid squares.
