Biosecurity New Zealand's manager of pest management, John Sanson, says water hyacinth is a rapidly growing water weed that if left, can form dense mats that reduce water quality, crowd out native water plants and animals, block irrigation systems and alter ecosystems. It also form micro habitat for some aquatic animals, birds and disease vectors. Water hyacinth has some uses, however.
